1 Clutter 1.11.4 2012-06-05
2 ===============================================================================
4 • List of changes since Clutter 1.11.2
6 - Multi-touch support fixes
7 The clutter_event_copy() code was copying the wrong axis data; the correct
8 touch device was not used when translating axis data from XInput2 to the
9 ClutterInputDevice; touch events were not delivered to the correct actors.
11 - Add ClutterDropAction::drop-cancel signal
12 The ::drop-cancel does what it says on the tin: it allows handling a
13 cancelled drop action, instead of relying on the drag end signal on
14 the ClutterDragAction.
16 - Add examples in the repository
17 Clutter has been using some interactive tests as examples of idiomatic
18 usage, both as standalone code and for inclusion inside the API reference
19 documentation; this is sub-optimal, as the interactive tests are meant to
20 exercise the API and its behaviour, not as an example of how to write
21 proper Clutter code. For this reason, we now have an examples/ directory
22 that contains example code that can be used to learn Clutter.
24 - Allow disabling the tests and examples when building Clutter
25 This should help cross-compilation and testing.
27 - Fix the preferred size to always include the actor's margin
29 - Fix picking of the ClutterScrollActor
31 - Add implicit animations for the color properties of ClutterText
32 Changing any color-related properties of a ClutterText actor will result
33 in a transition, if the easing state has a non-zero duration.
35 - Layout managers should respect the child expand and align properties
36 ClutterBinLayout, ClutterBoxLayout, and ClutterTableLayout should use the
37 ClutterActor [xy]-expand and [xy]-align properties, and deprecate their
40 - Make all layout managers respect the child easing state when allocating
41 ClutterLayoutManager also has properties that can be set to control all
42 the children's default easing state.
44 - Add ClutterTimeline::stopped signal
45 The ::stopped signal is emitted either when a Timeline reaches full
46 completion, including eventual repeats; or when the Timeline has been
47 stopped through clutter_timeline_stop(). A boolean argument passed to
48 the signal handlers should be used to distinguish the two cases.
50 - Add ClutterGridLayout
51 This layout manager implements the same layout policy of GtkGrid.
53 - Fixes for ClutterKeyframeTransition
57 - Fixes for building Clutter with Visual Studio
58 Including the GDK backend.
60 - Fixes for the Mac backend
61 Chain up to get a Cogl context after creating a GL context; this seems
62 to be enough to make the interactive tests run.

101 Clutter 1.11.2 2012-04-30
102 ===============================================================================
104 • List of changes since Clutter 1.10
106 - Add ClutterScrollActor
107 An actor that can display a portion of its children, as well as
108 transitioning between visible regions.
110 - Make clutter_actor_allocate() respect the easing state of the actor
111 This allows animating allocations in layout managers.
113 - Add automatic expansion flags for ClutterActor
114 Actors can be marked to by allocated extra space by their parent, or
115 by the layout manager used by their parent; the expansion flags are also
116 recursive, so they can be set on a leaf node of the actor tree, and
117 propagate further up automatically.
119 - Add ClutterTransitionGroup and ClutterKeyframeTransition
120 Two ClutterTransition implementation that allow creating complex
123 - Provide more C convenience API to ClutterTransition
124 Instead of dealing with ClutterInterval instances, it's possible to
125 define the starting and final values of a transition.
127 - Provide base geometric types: point, size, rectangle
128 Along with commodity API.
130 - New round of deprecations
131 ClutterMedia, ClutterCairoTexture, clutter_actor_animate(),
132 ClutterAnimation, ClutterAnimator, ClutterState, ClutterLayoutManager's
135 - Return a valid default PaintVolume in more cases
136 For actors not overriding paint() or get_paint_volume() we can already
137 infer enough information on the area thatis going to be painted, and return
138 a valid paint volume. We specifically ignore any painting going on inside
139 a ClutterActor::paint signal handler, as that is considered legacy and on
140 its way to deprecation. People overriding the paint sequence of an actor
141 from within a paint signal handler, and painting outside the allocation,
144 - Depend on Pango 1.30
146 - Report distance as an axis on X11 with XInput 2 support enabled
147 Proximity information with XInput 2+ is reported as axis data on devices
148 with valuator classes.

172 Clutter 1.9.16 2012-03-19
173 ===============================================================================
175 • Clutter 1.10.0, release-candidate 1
177 • List of changes since Clutter 1.9.14
179 - Support implicit animatable properties
180 Various properties of ClutterActor can now be implicitly animated when
181 using the public setters, instead of going through the animation API;
182 this is an opt-in mechanism for the 1.x API series.
184 - Introduce paint nodes
185 ClutterPaintNode is an element of the render tree; it is used to store
186 the pipeline state and the geometry to be drawn. Actors have the ability
187 to be painted using the paint nodes by overriding the paint_node() virtual
188 function instead of the paint() virtual function. For the 1.x API series
189 the render tree will be consumed per-actor, but the plan is to build a
190 full tree as the authoritative source for the 2.x API series.
192 - Support Content delegates
193 ClutterContent is an interface that allows creating classes that will
194 painted in place of an actor's paint() virtual function. Clutter provides
195 two content types: Canvas, a Cairo-based immediate canvas for drawing the
196 contents of an actor; and Image, a content that will paint image data.
198 - ClutterText improvements
199 The caret of editable text actors is now centered, and the background
200 color will be respected when painting the actor.
202 - Support for the XInput 2.2 extension
203 Clutter will now relay touch events coming from the X server, as well
204 as precise scrolling delta, for devices with those two capabilities.
205 The support is still experimental, and limited to the X11 platform for
208 - Translation updates

236 Clutter 1.9.14 2012-03-05
237 ===============================================================================
239 • List of changes since Clutter 1.9.12
241 - Support custom versioning boundaries for the API
242 Now that GLib provides macros for changing the minimum required and
243 maximum allowed version of a library, Clutter can respect the
244 boundaries expressed using CLUTTER_VERSION_MIN_REQUIRED and
245 CLUTTER_VERSION_MAX_ALLOWED.
247 - Add version information to deprecations
249 - Move all deprecated symbols to separate header files
251 - Documentation and annotation fixes.
253 - Accessibility fixes in Cally
254 Do not use ClutterActor:name as the accessible name, and do not
255 provide the extents of an accessible object if the actor to which
256 it refers is not on screen.
258 - Updates to the Wayland compositor and client support
259 Clutter now allows being used for creating hybrid Wayland/X11
260 compositors, working with KMS and evdev directly.
262 - Translation updates: Bulgarian, Ukranian, Galician, Uyghur, Belarusian,
263 Brazilian Portuguese, Telugu, Slovenian, Assamese, Serbian.

278 Clutter 1.9.12 2012-02-23
279 ===============================================================================
281 • List of changes since Clutter 1.9.10
283 - Add ClutterTimeline:repeat-count and deprecate :loop
284 The :repeat-count property supercedes the :loop property, and it
285 provides a way to specify the number of repeats that a timeline
286 should perform - with the option of specifying an "infinity" value.
288 - Add a progress mode for ClutterTimeline
289 This begins the "soft deprecation" of ClutterAlpha. Instead of
290 requiring a full object to compute an easing function out of a
291 linear progress coming from ClutterTimeline, we should have this
292 functionality on ClutterTimeline itself. Since ClutterAlpha is
293 still exposed in API that we cannot deprecate (such as virtual
294 functions) we cannot deprecate it fully, and we'll have to wait
295 until the 2.0 API bump to get rid of it.
297 - Fix ClutterBoxLayout allocation
298 Since the update of the box layout algorithm there have been a
299 bunch of regressions; now the layout works as intended.
301 - Improve the performance of the shader-based effect in Clutter
302 The effects shipped with Clutter now use the CoglSnippet API
303 internally, which allows efficient generation of the shader code;
304 they also ensure that the shader is generated once per class, and
305 shared across instances. These changes should improve performance
306 when using effects provided by Clutter.
308 - Update the internal usage of Cogl API
309 Clutter should strive to use the Cogl 2.0 API internally and not
310 mix the 1.0 and 2.0 API.
312 - Allow accessing Wayland input devices
313 This is a change that allows Clutter-based toolkits to interact
314 with Wayland in a meaningful way for operations like resize and
317 - Add a convenience CLUTTER_BIND_ALL enumeration
318 This allows binding both position and size of an actor when using
319 a ClutterBindConstraint.
322 Use the newly added API to reimplement focus tracking.
324 - Visual Studio project updates
326 - Add clutter_text_coords_to_position()
327 This method roundtrips the position_to_coords() one, and allows
328 retrieving the index of the character at the given actor-relative
331 - Documentation updates.
333 - Introspection annotation fixes.
335 • List of bugs fixed since Clutter 1.9.10
338 #669730 - actor: Fix and improve add_child_at_index()

349 ===============================================================================
351 • List of changes since Clutter 1.9.8
353 - Provide symbolic names for pointer buttons
354 The primary, middle, and secondary pointer buttons now have simple and
355 easy to remember constants that can be used in place of the "magic"
358 - Add ClutterActorIter
359 A simple API, using a stack allocated opaque structure, for safely and
360 efficiently traverse the children of a ClutterActor.
362 - Fix regression introduced by the default FixedLayout layout manager
363 Existing ClutterActor subclasses using their own layout management should
364 now work exactly like in Clutter 1.8.
366 - Documentation fixes
367 Including introspection annotations fixes.
369 - Updates to the Wayland backend
370 The Wayland client backend is now up to date with the 0.85 release of
371 the Wayland protocol.
373 • Bugs fixed since Clutter 1.9.8

387 Clutter 1.9.8 2012-01-24
388 ===============================================================================
390 • List of changes since Clutter 1.9.6
392 - Fix regressions in users of deprecated API
393 Also, allow to mix the new Actor API with the old Container API without
396 - Add GResource support in ClutterScript
397 GResource is a new infrastructure in GIO that allows to compile resources
398 like UI builder files and image data into a shared library or an
399 executable. A newly added method to ClutterScript makes it possible to
400 load a UI definition from a resource, like it's done for files and
403 - Update the Wayland client backend
404 The SHM transport API has changed upstream, and the Clutter backend has
405 been updated to reflect it.
409 Rob Bradford, Fran Diéguez
411 Clutter 1.9.6 2012-01-19
412 ===============================================================================
414 • List of changes since Clutter 1.9.4
416 - Deprecate clutter_actor_show_all() and clutter_actor_hide_all()
417 The latter never did make a lot of sense: hiding the parent will
418 effectively hide the children as well; the former was there only for
419 convenience, but Actors are visible by default.
421 - Gracefully handle existing code
422 The changes in ClutterActor introduced regressions in existing code
423 because of the new functionaly that was introduced to replace deprecated
424 classes like Box and Group. These regressions have hopefully been fixed;
425 Clutter 1.9.6 has been tested with a project as complex as the GNOME
428 - Fix build with binutils-gold
429 The private dependencies were not used when building Clutter, and this
430 made the Gold linker angry.
432 - Allow tracking of an actor's first and last child
433 ClutterActor has two new properties, :first-child and :last-child; these
434 are read-only properties that can be used by toolkits based on Clutter
435 to track the first and last child whenever they change.
437 - Bump the Cogl dependency
438 The 1.9.4 release depended on Cogl ≥ 1.9.4, but the minimum required
439 version was not bumped along with the changes.
441 • List of bugs fixed since Clutter 1.9.4
444 #668137 - FTBFS: pangoft2 check seems to be broken
446 Clutter 1.9.4 2012-01-17
447 ===============================================================================
449 • List of changes since Clutter 1.9.2
451 - New scene graph API in ClutterActor
452 ClutterActor now provides the API for adding, removing, and iterating
453 over the list of children; this deprecates most of the ClutterContainer
454 API. ClutterActor implements ClutterContainer as well, which means that
455 all actors can be containers.
457 - Layout management updates
458 ClutterActor now have an horizontal and vertical alignment properties
459 that will be used when added to a parent; a margin has also been added
460 to the ClutterActor class. Both margin and alignment will be automatically
461 managed during the allocation, so they will work out of the box. It is
462 also possible to set a ClutterLayoutManager delegate object on any
463 ClutterActor instance: the LayoutManager will take care of the layout
464 policy for the children of an actor.
466 - Add ClutterTextBuffer
467 The ClutterTextBuffer class provides a storage for the contents of
468 a ClutterText actor; the same instance can be shared across different
469 actors as well. The main use for ClutterTextBuffer is implementing
470 secure memory storage for the contents of a ClutterText in password
474 ClutterGroup, ClutterBox, and ClutterRectangle have been deprecated; their
475 functionality is now available directly in ClutterActor. The old child
476 actor management API in ClutterActor and ClutterContainer has been
477 deprecated as well. Other deprecations include the ClutterStage
478 fog-related properties and API; the ClutterContainer.sort_depth_order(),
479 raise(), and lower() virtual functions; the internal child push and
480 pop methods on ClutterActor.
482 - ClutterTimeline can parse markers from ClutterScript
483 Markers can now be defined inside ClutterScript, and a ClutterTimeline
484 will be able to automatically add them from a UI definition.
486 - Add a diagnostic mode
487 Similar to the GLib diagnostic mode, Clutter now supports an environment
488 variable that will print out diagnostic messages for deprecations and
489 warnings that can only be detected at run-time.
491 - Wayland backend updates
492 The wayland backend now tracks the latest API changes in the client API,
493 and Clutter now provides a Wayland surface actor that allows to write
494 Wayland compositors, similarly to the X11TexturePixmap actor for the
497 • List of bugs fixed since Clutter 1.9.2
500 #665040 - The offscreen effect always recreates the texture if
501 create_texture() is overridden to change the size

520 Clutter 1.9.2 2011-11-22
521 ===============================================================================
523 • List of changes since Clutter 1.8
525 - Multi-backend build, and run-time backend selection
526 Clutter can be built with support for multiple backends in the same
527 shared library; the backend singleton is determined at run-time,
528 either with the default backend for the platform, or using the value
529 of the CLUTTER_BACKEND environment variable.
531 - GDK windowing system backend
532 A new backend has been added, which uses the GDK API for creating the
533 drawing surface, as well as receiving the windowing system and input
536 - Show a hint when ClutterText is in password mode
537 If the password-hint-time ClutterSettings property is set to a non
538 zero value, the last character entered inside a ClutterText actor when
539 in password mode will be shown in plain for the duration of the timeout,
540 before being replaced by the glyph chosen as the password character.
542 - Improve Windows build support
543 Clutter now provides project files to build the library using Visual
544 Studio 9 and Visual Studio 10. Also, the scripts to build Clutter using
545 MinGW have been improved.
547 - Remove the requirement for using clutter_threads_init()
548 Threads are initialized by default (depending on the platform), so there
549 is no need to call clutter_threads_init().
551 - Deprecate the default ClutterStage
552 The semantics of the default Stage were not obvious, and had the tendency
555 - Move the deprecated headers into their own directory
556 This should help developers identify the deprecated API.
558 - Change deprecation policy
559 Deprecated functions are now marked using compiler annotations, instead
560 of being forcibly disabled through pre-processor directives from the
561 headers. Deprecations will cause compiler warnings, and thus are enabled
562 by default. If you're building your project with compiler flags that
563 consider every warning a fatal error, you can use the symbol
564 CLUTTER_DISABLE_DEPRECATION_WARNINGS to disable the deprecation warnings.
566 - Translation updates
567 Portuguese, Assamese, Punjabi, Tamil, Oriya, Telugu, French, German,
568 Danish, Traditional Chinese (Hong Kong and Taiwan), Catalan, Esperanto,
569 Lithuanian, Galician, Norwegian bokmål, Slovenian, Hebrew, Bulgarian.

616 Clutter 1.7.90 2011-09-12
617 ===============================================================================
619 • List of changes since Clutter 1.7.14
621 - Make sure that setting :use-markup does not depend on the order
622 Setting the :use-markup property should yield the same results regardless
623 of whether the :text property is also set before or after. This applies to
624 ClutterText defined using ClutterScript as well.
626 - Protect against multiple unrealize call on ClutterStage
627 This should fix a segmentation fault in clutter-gtk when unrealize() is
628 called multiple times on an already unrealized stage.
630 - Fortify ATK event listener
631 Make sure that we subscribe only to the events we want to, and avoid
632 warnings caused by AT-SPI, as well as a leak.
634 - Documentation fixes
636 - Translation updates

659 Clutter 1.7.14 2011-09-05
660 ===============================================================================
662 • List of changes since Clutter 1.7.12
664 - Use newer version of ATK
665 Cally now depends on the latest version of ATK, to reduce the amount of
666 ad hoc code needed and to use newer features that simplify the
667 implementation of accessible objects in Clutter.
669 - Allow using Layout Managers with generic containers
670 Layout managers should not assume that they are allocating the whole
671 area available from the Actor using them; this allows actors that
672 support concepts like padding or margin to use a LayoutManager internally
676 Add a recipe on how to bind a ClutterState to the signals of objects
677 defined in ClutterScript. We also install the cookbook examples inside
678 the $datadir/clutter-1.0/cookbook/examples directory.
680 - Improve examples in the API reference
681 Some of the interactive test suite units are actually good examples of
682 how to use the Clutter API; we can use the XInclude tags to include the
683 source code inside the API reference.
685 - Ensure thread safety of the repaint functions add/removal
686 Fix a long standing issue where adding or removing repaint functions
687 was not acquiring a lock; now it's safe to manipulate the repaint
688 functions list from different threads.
690 - Make the ClutterText:line-wrap property work again
691 In 1.2 the :line-wrap property was broken, and ClutterText would paint
692 a PangoLayout wrapping until it fit the height of the allocation
693 regardless of whether the :line-wrap property was set to FALSE or
694 TRUE. Now we clip the PangoLayout before rendering it, if the :line-wrap
695 property is set to FALSE and there is no ellipsization policy set.
697 - Disable redirection to offscreen buffer by default
698 Whenever a ClutterActor with children was not fully opaque, the actor
699 was redirected to an FBO, to perform correct opacity computations.
700 Sadly, this can lead to 3x slowdowns, given the amount of framebuffer
701 objects created and the state changes that have to be performed. We
702 decided to turn off this feature by default, to avoid the performance
703 hit. It is still possible to enable this feature on a per-actor basis,
704 though, and will work to reduce the hit in future versions of Cogl,
705 Clutter and the drivers.

711 #657681 - Crash when destroying an actor while dragging it

723 Clutter 1.7.12 2011-08-29
724 ===============================================================================
726 • List of changes since Clutter 1.7.10
728 - Reload the font caches on X11 when the user installs a new font
729 Whenever the user installs a new font inside one of the directories that
730 ware being watched by a session daemon, or changes the fontconfig
731 configuration, the toolkits using FontConfig (either directly or indirectly
732 e.g. through Pango, like Clutter) should listen to the Fontconfig/Timestamp
733 XSETTINGS key and release all the font configuration caches. This allows
734 selecting the newly installed fonts without requiring the user to restart
737 - Allow using "font-description" as a ClutterScript alias for "font-name"
738 ClutterText:font-description allows passing a PangoFontDescription
739 directly to a ClutterText; when defining a ClutterText instance inside a
740 ClutterScript file, :font-description should be an alias for :font-name,
741 which takes a string and converts it to a PangoFontDescription.
743 - Make sure that LayoutManager subclasses take the allocation origin
744 into account when allocating the children
745 A LayoutManager should be resilient against allocations with an origin
746 not positioned at (0, 0); this allows actors using a layout manager
747 instance to munge the box and implement things like margin and padding
748 without the layout manager having knowledge of those concepts.
751 Always link against libm when building Clutter (and its tests); don't
752 rely on libraries lower on the stack to do so.
754 - Documentation fixes

767 ===============================================================================
769 • List of changes since Clutter 1.7.8
771 - Do not update the last paint volume when picking
772 Last minute fix for an issue that was most prominently manifesting itself
773 when using GNOME Shell with Clutter 1.7; this should resolve the issue
774 that dragging icons from the dash left around some stale pixels.
776 - Fix building the tests
777 The performance and micro-benchmark tests did not pick up changes in
778 local dependencies, e.g. under a JHBuild root.

790 Clutter 1.7.8 2011-08-15
791 ===============================================================================
793 • List of changes since Clutter 1.7.6
795 - Various fixes in Cally
796 Make sure to use Clutter's API and remove old workarounds that were put
797 into place when Cally was a separate project and targeting pre-1.0 API
800 - Add ClutterCairoTexture:auto-resize
801 This property makes it easier to create 2D canvas surfaces by tracking
802 the actor's allocation in a backward compatible way.
804 - Add ClutterAnimatable.interpolate_value()
805 This new virtual function deprecates the animate_property() virtual of the
806 Animatable interface, which was sub-optimal in different ways.
808 - Allow using Animatable implementations with ClutterState
809 Thanks to the new interpolate_value() virtual it is now possible to use
810 the Animatable interface with ClutterState; this allows animating
811 action, constraint and effect properties using the same "@" syntax also
812 used by ClutterAnimation and clutter_actor_animate().
814 - Improve ClutterModel's implementation
815 Avoid a bunch of needless checks, and make sure that the ::row-changed
816 signal is emitted in all cases when a row has been changed through the
817 ClutterModelIter API. The conformance test unit for ClutterModel has
818 also been improved to avoid future regressions.
820 - Improve ClutterStage behaviour on OS X
821 Make sure that the fullscreen, multi-screen and key focusing are
822 well-behaved on OS X, by implementing the correct delegate methods.
824 • List of bugs fixed since Clutter 1.7.6
828 #655387 - Missing GObject introspection annotations

844 Clutter 1.7.6 2011-07-26
845 ===============================================================================
847 • List of changes since Clutter 1.7.4
849 - Accessibility fixes in Cally
850 Fix the implementation of the AtkText interface for ClutterText.
852 - Depend on the new Cogl windowing system API.
854 - Add functions for retrieving the clip boundaries on the Stage
855 The clutter_stage_get_redraw_clip_bounds() function is useful for
856 window managers (like Mutter) that need to retrieve the clipped
857 region used on the Stage.
859 - Auto-detect the default flavour when building
860 The default flavour used when building should be set depending
863 - Mark the OSX backend as non-experimental
864 The OSX backend is being developed, and maintained, so it should
865 not be considered experimental.
867 - Make sure that Gestures are cancelled when missing release events
869 - Correct the rounding for paint volumes
870 Try to provide stable results against potential floating point rounding
871 margins when projecting 3D paint volumes into screen bounding boxes;
872 this should avoid re-creating FBOs and always correctly handle clipped
875 - Do not clobber XI2 events data
876 This allows to play along with other toolkits using XI2.
878 - Fix ClutterSnapConstraint's right edge snapping
881 ClutterScore, clutter_texture_new_from_actor(),

915 Clutter 1.7.4 2011-07-04
916 ===============================================================================
918 • List of changes since Clutter 1.7.2
920 - Unify the GLX and EGL backends to be a single code base
921 The GLX and EGL backends shared most of their code, and with the split
922 out Cogl, we can unify the code base into a single backend. The API as
923 well as the ABI are preserved.
925 - Restore a wider range of Z values for actors
926 The computation for the near and far planes given the perspective
927 transformation used to set up the viewport was broken in 1.7.2, and
928 the distance from the focal point was greatly reduced. This has now
931 - Bump up the dependency of Cogl
932 New windowing system API in Cogl required bumping the minimum version
933 to the latest development snapshot, 1.7.2.
935 - Add ClutterDropAction
936 The ClutterDropAction is an action for allowing ClutterActors to react
937 when an actor being dragged through ClutterDragAction crosses, or is
940 - Add a performance test suite
941 This suite is an addition to our conformance and interactive test
942 suites; the infrastructure can be used by buildbots and report tools
943 to track performance regressions across various commits.
945 - Documentation and annotation fixes

977 Clutter 1.7.2 2011-06-13
978 ===============================================================================
980 • List of changes since Clutter 1.6.0
982 - Cogl moved out of tree
983 The Clutter OpenGL abstraction library has been moved to a separate
984 repository and can be used as a stand-alone shared library. Clutter
985 has been modified to depend on Cogl's experimental API.
987 - Correctly composite non fully opaque children
988 Non fully opauqe actors with non fully opaque children will automatically
989 redirect children paint operations to offscreen buffers, which allow
990 correct composition taking into account the overall opacity of the scene's
991 sub-graph. The same mechanism can be used to create a paint cache, and
992 paint that cache when the actor or its children do not change, instead of
993 painting the whole sub-graph again.
995 - Allow connecting signals to ClutterState states in ClutterScript
996 When defining a scene using ClutterScript it's possible to directly
997 connect a state inside a ClutterState object (both defined in
998 ClutterScript or in code) to an object's signal, without using an
999 explicit signal handler in the code.
1001 - Long-press handling in ClutterClickAction
1002 ClutterClickAction will detect a long-press gesture and emit signals
1003 to query, activation and cancellation.
1005 - Added ClutterGestureAction and ClutterSwipeAction
1006 ClutterGestureAction is a generic "pointer gesture" action; it doesn't
1007 provide an implementation: it's up to the developer to add the gesture
1008 recognition code. ClutterSwipeAction is a GestureAction sub-class that
1009 implement the "swipe" gesture. The GestureAction API is already future
1010 proof for multi-device/multi-touch, even though the multi-touch isn't
1011 currently implemented.
1013 - Allow Effects to influence picking
1014 Effects that change the geometry of a ClutterActor should also be
1015 allowed to change the picking code to make sure that event handling
1016 keeps working. ClutterEffect has a new pick() virtual function for

1237 Clutter 1.5.14 2011-01-24
1238 ===============================================================================
1240 • List of changes since Clutter 1.5.12
1242 » Allow getting the state modifiers from a ClutterClickAction.
1244 » Fix ClutterDragAction to never leave the event delivery in
1247 » Optimize state changes for texture and data states.
1249 » Enable VBO support in Cogl for GLES2.
1251 » Fix compilation on GLES1.1.
1253 » Documentation fixes.
1255 » ClutterGLXTexturePixmap has been deprecated; its parent class
1256 ClutterX11TexturePixmap and the low level CoglTexturePixmapX11
1257 API provide access to the same features.
1259 » Be more resilient against timelines controlling the state of
1260 other timelines during the clock tick.
1262 » Provide defines for the windowing platforms, to allow portable
1263 applications to include the correct header and select the
1264 correct API depending on the target.
1266 » Introduce a fast path for cogl_read_pixels() that uses the journal
1267 to determine the position of a single pixel on the stage; this
1268 fast path gracefully degrades to the usual render-based approach,
1269 and should speed up picking considerably in the case of opaque
1270 quads batched together.
1272 » Support XInput axis data on valuator devices, and introduce XInput2
1273 support for event translation and device hotplugging. The support
1274 for XI and XI2 must still be explicitly enabled by the developer,
1275 but it is now compiled in by default. It can be disabled at compile
1276 time by passing --disable-xinput to the configure script.
1278 » Clean up the unintentionally leaked internal symbols in the X11
1281 » Allow defining the contents of the rows of a ListModel using
1282 ClutterScript. This completes the ability to fully define a
1283 ClutterListModel inside a UI definition file.

1338 » Fix the core device list creation on X11.
1340 » Avoid enabling blending in the Cogl journal, if possible.
1342 » Documentation fixes.
1344 » Build fixes for mixed autotools version environment.
1346 » Improve the performance of getting the number of rows of a

1368 » Update the build scripts for compiling the Windows backend.
1370 » Updates for the Cookbook and the API references.
1372 » Fix ClutterModel::get_iter_at_row() for filtered ClutterListModels.

1377 up batches of primitives.
1379 » Keep a cache of ARBfp programs indexed by the pipeline state that
1380 led to their generation.
1382 » Accept G_TYPE_DOUBLE values in ClutterShaderEffect uniforms.
1384 » Update the Wayland client backend.
1386 » Update the build for Windows.

1402 • List of changes since Clutter 1.5.6
1404 » Add a migration guide for code using Behaviours.
1406 » Allow parsing rgb(), rgba(), hls() and hlsa() color definitions.

1410 » For caching purposes, do not discard the Material or the compiled
1411 shaders for Offscreen and Shader effects.
1413 » Fix image height in 3D Cogl textures.
1415 » Create a GLSL generation backend for materials, similar to the
1416 ARBfp one; this backend is the default for GLES2.
1418 » Use FBOs and cogl_read_pixels() to efficiently read back partial
1421 » Various fixes in paint volumes computation and caching.

1442 Clutter 1.5.6 2010-11-19
1443 ===============================================================================
1445 • List of changes since Clutter 1.5.4
1447 » Deprecate ClutterBehaviour and its sub-classes: the same functionality
1448 is available using the animation framework.
1450 » Add ClutterSnapConstraint, a constraint implementation that snaps
1451 together the edges of two actors.
1453 » Add ClutterPathConstraint::node-reached.
1455 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
1456 not used internally any more, and since it's not integrated with
1457 the master clock it's of relative use.
1459 » Add a named, global color palette.
1461 » Add the ClutterTimeline:reverse property, for automatically
1462 reversing the direction of a timeline after the emission of
1463 the ::completed signal.
1465 » Performance improvements in the clip stack.
1467 » Do not use pointer grabs in ClutterClickAction.
1469 » Improve the internally used Cogl API for primitives, paths and
1470 buffers; this is the first step towards Cogl 2.0.
1472 » Allow using the COGL_DEBUG environment variable to disable the
1475 » Plug a nasty infinite loop in the XSETTINGS implementation.
1477 » Internally rename CoglMaterial to CoglPipeline; this should make
1478 it clearer that the API refers to the state of the GPU pipeline.
1480 » Add support for clipped redraws on EGL using the NOK_swap_region
1485 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
1487 » Update examples in the Cookbook.

1547 Clutter 1.5.2 (04/10/2010)
1548 ===============================================================================
1550 • List of changes since Clutter 1.4.0
1552 » Add API to ClutterActor to allow any actor to define its 3D paint
1553 volume and its stage-relative 2D bounding box; the paint volume is
1554 the 3D space occupied by an actor during the paint sequence. This
1555 allows better sizing of the FBOs, and opens the door to scenegraph
1556 culling and accurate clipped redraws. The mechanism is opt-in: actors
1557 have to implement the get_paint_volume() virtual function. Callbacks
1558 attached to the ::paint signal will also disable any culling and
1559 clipped redraw in place internally.
1561 » Plug a leak in ClutterActor by disposing all constraints.
1563 » Rework the build system to be as non-recursive as possible; this should
1564 speed up the build of Clutter, and makes the build layout easier to
1565 understand and update.
1567 » Remove the internal copy of JSON-GLib; the internal copy was falling
1568 behind at a spectacular level, and it was actually making the build
1569 rather complicated - also by adding an unwanted, but needed,
1570 introspection data generation. The required JSON-GLib has also been
1571 bumped to the new stable release, 0.12.0.
1573 » Use g_object_install_properties() with GLib 2.26.
1575 » Implement ClutterContainer::child-notify, which slipped through the
1576 cracks of many development cycles without anyone noticing.
1578 » Document and test clutter_actor_contains(), especially the corner
1581 » Plug a leak in CoglTexture2DSliced.
1583 » Plug a leak in ClutterAnimator's handling of timelines.
1585 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
1586 errors when the GLX pixmap is destroyed behind Cogl's back.
1599 Clutter 1.4.0 (24/09/2010)

1647 - reusing complex animations
1649 » Add methods to retrieve the clicked button and to force a release
1652 » Documentation fixes in the API reference.
1654 » Cache a full pick buffer and re-use it in case the scene does not change
1657 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
1659 » Allow detaching animations created with clutter_actor_animate().
1661 » Depend on GObject-Introspection >= 0.9.5.
1663 » Provide introspection data for the X11-specific API, like
1664 ClutterX11TexturePixmap
1666 » Use a template material for ClutterTexture to minimize the creation of
1669 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
1670 :x-drag-threshold and :y-drag-threshold.
1672 » Allow disabling the -Bsymbolic flag when linking.
1674 » Use gettext >= 0.17 to handle the localization.
1676 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
1677 a crash when dealing with clip stacks.
1679 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
1680 freeing the X11 Pixmap to avoid an error.
1682 » Avoid regenerating the CoglMaterial programs too many times.
1703 Clutter 1.3.12 (16/08/2010)

1727 » Re-use the Cogl texture atlas for the CoglPango glyphs cache,
1728 and improve the performance with large font sizes.
1730 » Various fixes in the Materials comparison and inheritance.

1752 keys to key symbols.
1754 » Documentation fixes in the API reference.

1805 » Add missing public functions from COGL headers.
1807 » Fix GLES build after the Cogl material changes.
1809 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
1811 » Split the clutter_state_change() method into two:
1812 clutter_state_set_state(), for animated state changes; and
1813 clutter_state_warp_to_state() for immediate state changes.
1815 » Documentation and introspection fixes.
1829 Clutter 1.3.6 (30/06/2010)
1830 ===============================================================================
1832 • List of changes since Clutter 1.3.4
1834 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
1835 available, by using EXT_framebuffer_blit. Both mechanisms are also
1836 throttled to avoid taking all resources when using them in a compositor
1839 » Use (and cache) fragment shaders instead of texture combiners inside
1840 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
1841 to fixed functions depending on the level of support of the underlying
1844 » Implement a new design for materials; this allows scaling up the
1845 number of materials in a scene, and also makes copying materials
1848 » Make Cogl materials responsible for depth testing, and add new
1851 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
1852 object instead of using the stencil buffer, or the scanline rasterizer
1853 on platforms without a stencil buffer.
1855 » Add ClutterDeformEffect, a base class for effects that deform an
1856 actor's geometry when painting it; ClutterPageTurnEffect is an
1857 implementation of a "page curl" deformation using the DeformEffect
1860 » Always use scissoring when clipping, to reduce the amount of buffer
1861 that has to be cleared.
1863 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
1864 a constructor property; the default remains fragment shader.
1866 » Remove the button of the press event from the DragAction::drag-begin
1867 and DragAction::drag-end signals. This is an API break from 1.3.4.
1869 » Do not promote clipped redraws to full redraws.
1871 » Improve the consistency of the default state name in ClutterState,
1872 both in the API and in the serialization format.
1874 » Fix a rounding error with the Text layout size.
1876 » Add utility functions for CoglMatrix and CoglColor.
1878 » Avoid a re-allocation cycle warning when resizing the surface of
1879 a CairoTexture actor from within the allocate() implementation.
1881 » Do not add the GL libraries for the EGL X11 backend.
1883 » Add more checks for size of data passed to the shader types GValue
1886 » Add width and height to the BindConstraint.
1888 » Parse actions, constraints and effects inside an actor definition
1891 » Merge the code of native and x11 backends for EGL into a single
1892 backend; also allow creating GL context with the EGL backend.
1894 » Use XSETTINGS to set up the backend configuration options, like
1895 the font name, resolution, font options and double click options,
1896 on X11; this also allows ClutterText actors created using the
1897 default font name to be updated when the font name and options
1898 change; similarly, this allows ClutterUnits to be updated when
1899 the screen resolution changes.
1901 » Implement the texture_from_pixmap extension support inside Cogl
1902 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
1904 » Documentation improvements in the API reference and in the cookbook.
1906 » Use the -Bsymbolic-functions linker option on supported platforms
1907 to avoid intra-library PLT jumps.
1909 » Fix painting transparent stages on X11 using the :use-alpha property
1912 » Fix emission of scroll events on Windows.
1931 Clutter 1.3.4 (07/06/2010)
1932 ===============================================================================
1934 • List of changes since Clutter 1.3.2
1936 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
1937 way an actor paints itself.
1939 » Clutter provides a base class for effects painting to an
1940 offscreen buffer, and a base class for effects using the
1941 GL programmable pipeline (through the GLSL shader language).
1943 » Clutter also provides some simple, shader-based effects:
1944 ClutterBlurEffect, ClutterColorizeEffect and
1945 ClutterDesaturateEffect.
1947 » Effects can be applied to any actor, and can also be stacked.
1949 » Add ClutterClickAction, an action that provides "button-like"
1950 semantics for any ClutterActor.
1952 » ClutterDragAction now moves the actor to which it has been applied
1953 by default, using a class handler for the ::drag-motion signal.
1955 » Add the :pick-with-alpha property to ClutterTexture; this property
1956 allows using the alpha channel of a texture when picking it.
1958 » Regenerate the mipmaps on COGL textures when a texture is modified.
1960 » Documentation and build fixes.
1969 Clutter 1.3.2 (24/05/2010)

1978 related to event handling.
1980 » Add ClutterConstraint, a class for implementing business
1981 logic related to sizing and positioning.
1983 » ClutterDragAction is an Action sub-class that implements
1984 signals and properties for dragging actors.
1986 » ClutterAlignConstraint and ClutterBindConstraint are two
1987 Constraint sub-classes that allow relative positioning
1988 with fixed layout managers.
1990 » Add ClutterState, an object for defining state transitions.
1992 » Add ClutterBoxLayout:homogeneous property.
1994 » Implement retained clip stacks.

2005 an AtkObject from a ClutterActor.
2007 » Improve ClutterText's Pango layout caching mechanism.
2009 » Fix set up of the GLX_SGI_swap_control extension.

2055 of JSON-GLib to which we fall back in the absence of the system
2058 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
2068 Clutter 1.2.0 (02/03/2010)

2089 ClutterScript definitions
2091 » Add support for unsigned integer indices in the VertexBuffer API
2093 » Documentation fixes for Clutter: the coverage is now 100%
2095 » Fixes for the EGL native backend
2097 » Require libtool >= 2.2.6
2099 » Improve tests coverage
2110 Clutter 1.1.14 (24/02/2010)
2111 ===============================================================================
2113 • List of changes since Clutter 1.1.12
2115 » Fix interaction between user resizable Stages and fullscreen on X11
2117 » Define the semantics of ENTER and LEAVE events when actors are on the
2118 border of the Stage window
2120 » Take the InputDevice of an event into consideration when throttling
2123 » Round the coordinates when clipping to a rectangle in window coordinates
2125 » Always trust the user-provided coordinates when creating a CoglTexture
2126 from a foreign GL texture
2128 » Split Clutter's debug annotations from the pick and paint mode
2129 behavioural modifiers
2131 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
2132 actor using a ClutterFixedLayout manager will automatically benefit
2135 » Fix the packing order of ClutterBox so that the convention of
2136 first-in-first-painted is maintained
2138 » Documentation fixes
2146 Clutter 1.1.12 (16/02/2010)
2147 ===============================================================================
2149 • List of changes since Clutter 1.1.10
2151 » Fix compilation on 64bit platforms
2153 » Fix some races of the Stage resizing on X11
2155 » Documentation fixes for Cogl: the coverage is now 100%
2157 » Fix rounding errors in the preferred height of the ClutterText
2160 » Remove redundant type checks in clutter_actor_get_paint_opacity()
2162 » Add support for the GLX_INTEL_swap_event extension; when using this
2163 extension on GLX the glXSwapBuffers() call becomes non-blocking and
2164 Clutter will use an event to control the master clock.
2166 » Improve consistency between ClutterBox and ClutterGroup.
2168 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
2169 Stage X window if the window was not created by Clutter itself
2171 » Improve caching of GL constant values
2173 » Optimize creating sub-textures of sub-textures
2175 » Various fixes for the atlas and the journal
2177 » Disable the atlas if FBOs are not supported
2187 Clutter 1.1.10 (09/02/2010)
2188 ===============================================================================
2190 • List of changes since Clutter 1.1.8
2192 » Fixed a regression in textures that caused all the textures to be
2193 drawn as white rectangles.
2195 » Fixed compilation with the Sun C compiler.
2197 » Use SSE2 instructions to premultiply RGBA images, if available.
2199 » Improve readability of ClutterActor::raise/::lower warnings.
2206 Clutter 1.1.8 (08/02/2010)
2207 ===============================================================================
2209 • List of changes since Clutter 1.1.6
2211 » Added ClutterAnimator, a class that allows defining complex
2212 implicit animations involving multiple actors and states; this
2213 class is mostly meant to be used through the ClutterScript
2214 definition format, but it provides a convenience C API for
2215 easily building animations.
2217 » New experimental COGL API to expose "hardware" buffers such as PBOs or
2218 drm surfaces. This API can be used, for instance, to make texture
2221 » Fixed the issues with resizable stages getting a 1x1 window with
2224 » Expose input devices for every event; by default, X11 and Windows
2225 backends expose the core devices only.
2227 » Add the ClutterStage:key-focus property, for key focus tracking.
2229 » Allow setting transformable value types in ClutterAnimation when
2230 calling clutter_animation_bind() and clutter_animation_update().
2232 » Delay the creation of the default Stage until clutter_stage_get_default()
2233 is actually called; this reduces the work of clutter_init().
2235 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
2237 » Improve the extendability of CoglTexture with internal backends.
2239 » Add implicit texture atlasing; Cogl will try to put every texture
2240 inside the same texture atlas by default, to avoid state changes
2241 in the driver and (hopefully) improve performance.
2243 » Fix notification of the cursor and selection changes in ClutterText;
2244 this improves the usage of Clutter from A11Y toolkits.
2246 » Do not wait for a frame if the system clock goes backwards.
2248 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
2250 » Documentation and build fixes.
2263 Clutter 1.1.6 (18/01/2010)
2264 ===============================================================================
2266 • List of changes since Clutter 1.1.4
2268 » Some fixes for the Win32 backend (bug #1905).
2270 » Profiling support via the UProf library. Configure with
2271 --enable-profile to get a report after each Clutter application is
2274 » Improved conformance tests with coverage reports via gcov.
2276 » ClutterTexture no longer tries to read back texture data into
2277 g_malloc'd memory on unrealize (bug #1842).
2279 » The CGL_• defines from cogl-defines.h have been removed. These
2280 should not have been used by any applications, but if they were
2281 being used then please replace them either with the Cogl enums or
2282 with the appropriate GL_• enum if you are using GL directly.
2284 » Added a delete-event signal to the stage.
2286 » Fix for using cogl_rectangle with different texture coordinates
2287 for multiple layers (bug #1937).
2289 » Fix for using stencil and depth buffers in FBOs on Intel drivers
2290 in Mesa (bug #1873).
2292 » Support for subtitles in ClutterMedia.
2294 » ClutterGLX will now use an RGB visual by default. For
2295 applications (and toolkit integration libraries) that want to
2296 enable the ClutterStage:use-alpha property there is a new
2297 function: clutter_x11_set_use_argb_visual().
2299 » Fix ClutterText to allow using Pango markup and attributes in
2300 the same actor (bug #1940).
2312 Clutter 1.1.4 (03/01/2010)
2313 ===============================================================================
2315 • List of changes since Clutter 1.1.2
2317 » Update the ClutterScript parser to be more resilient, and support
2318 constructor and ChildMeta properties. The parser also respects the
2319 order of the properties in the UI definitions when applying them,
2320 and will apply the properties of an Actor after building the scene
2323 » Simplified the implementation of LayoutManager sub-classes, and added
2324 support for animating a layout manager.
2326 » Allow short-circuiting some layout operations by setting a specific
2327 flag on ClutterActor.
2329 » Improve caching of the preferred size of a ClutterActor.
2331 » Allow declaring "internal children" for a ClutterContainer
2332 implementation: the memory management of these actors will be deferred
2333 entirely to the Container.
2335 » Let the ClutterStage honour the :opacity property and the alpha component
2336 of the stage color. This requires support in the Clutter backend used.
2338 » Improve Windows and OSX backends.
2340 » Simplify the feature detection code for OpenGL; this also reduced the
2341 required OpenGL version to 1.2.
2343 » Improve the matrix stack handling code. The matrices can be debugged by
2344 using the COGL_DEBUG environment variable, assuming that Clutter was
2345 compiled with the right configure-time switch.
2347 » Improve COGL API for draw buffers, and for offscreen buffer support.
2349 » Add support for text direction to ClutterActor.
2351 » Documentation, introspection and build fixes.
2368 Clutter 1.1.2 (23/10/2009)
2369 ===============================================================================
2371 • List of changes since Clutter 1.0
2373 » Add ClutterLayoutManager, an abstract proxy class for easily
2374 writing layout management policies; also add ClutterLayoutMeta,
2375 a class for storing layout properties.
2377 » Add ClutterBox, a generic container actor that relies on a
2378 ClutterLayoutManager instance to manage the layout of its
2381 » Add the following layout managers:
2383 - ClutterFixedLayout - a layout manager implementing the
2384 policy used by ClutterGroup
2386 - ClutterBinLayout - a layout manager for packing actors
2387 as layers inside the same area, with per-actor alignment
2389 - ClutterFlowLayout - a layout manager arranging actors as
2392 - ClutterBoxLayout - a layout manager arranging actors as
2395 » Remove the requirement for the backend-specific implementation
2396 of ClutterStage to be a ClutterActor: a Stage implementation must
2397 only implement the ClutterStageWindow interface. This cleans up
2400 » COGL source tree clean up and rationalization; COGL now
2401 knows the platform, and not only the driver (GL or GLES) so
2402 we can migrate part of the low-level backend code from Clutter
2403 to COGL where it makes sense.
2405 » Remove code duplication across whole COGL.
2407 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
2408 have been fixed and confirmed working.
2410 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
2411 dumps the contents of each pick() buffer into a PNG file, for
2414 » Allow interpolating intervals of ClutterUnits for animating
2415 unit-based properties.
2417 » Increase strictness and correctness of the ClutterUnits
2420 » Add GValue transformation functions for ClutterPath to and
2423 » Fix word movement in ClutterText; implement GObject getter for
2424 :use-markup; emit notification for :position; decouple the
2425 :text property from the :use-markup property.
2427 » Do not queue redraws or relayouts on actors currently being
2430 » Support #rrggbb and #rgb notations for ClutterColor.
2432 » Multiple bug fixes.
2434 » Provide _NET_WM_PID on the X11 stage implementation.
2436 » Documentation and Introspection annotation fixes.
2438 » Add test units for the ClutterActor size requesition.
2442 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
2443 back to Shave on older Automake versions.
2463 Clutter 1.0.0 (28/07/2009)
2464 ===============================================================================
2466 • List of changes since 0.9.8
2468 » Allow per-stage disabling of motion event throttling; this should allow
2469 platforms or applications that require all the motion events not for
2470 drawing purposes to get them exactly like Clutter gets them from the
2473 » Various documentation fixes.
2475 » Add per-word key navigation inside ClutterText.
2477 » Fix the RGB<->HLS conversion.
2479 » Various fixes for the OSX backend.
2481 » Various build-related fixes.
2489 Clutter 0.9.8 (17/07/2009)
2490 ===============================================================================
2492 • List of changes since 0.9.6
2494 » Add more introspection annotations for language bindings.
2496 » Fix a bug in clutter_animation_set_alpha(), which also broke the
2497 clutter_actor_animate_with_alpha() function.
2499 » Check if the stage requires a relayout before showing it; this fixes
2500 a bug in the X11-based backends, especially under compositing window
2501 managers, where a 640x480 window would flicker before the default
2502 stage was shown for the first time.
2504 » Performance fixes for Cogl.
2506 » Sliced textures were broken by the COGL journalling.
2508 » Use the redraw cycle when asynchronously loading textures from
2511 » Miscellaneous compilation fixes for the OS X and Windows backends.
2513 » Allow querying from within the paint function of an Actor whether
2514 the actor is currently being directly painted or by a Clone actor.
2516 » In the GLX backend, when using the non-implicit sync-to-vblank inside
2517 glXSwapBuffers(), call glFinish() to avoid potential tearing.
2527 Clutter 0.9.6 (01/07/2009)
2528 ===============================================================================
2530 • List of changes since 0.9.4:
2532 » Allow the manipulation of the actor's transformation matrix, so that is
2533 is possible to apply additional transformations in a way that is
2534 compatible with the transformations already applied by the scene graph.
2536 » Fix a race in the X11 backend that happened between resizing the stage
2537 drawable and the call to glViewport().
2539 » Merge the cogl-journal-batching branch; this branch implements batching
2540 the geometry of the elements of the scene graph before sending it to
2541 OpenGL, thus minimizing the number of state changes and improving the
2542 overall performance of Clutter-based applications.
2544 » Add more debugging states for Clutter and COGL, which allow the developer
2545 to track the state of the journal; to check the VBO fallback paths; to
2546 disable picking for reliable profiling; to disable software-side matrix
2547 transformations in favour of the driver/GPU ones.
2549 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
2550 semantics; applications that drop into raw GL are, though, ignoring all
2551 the caching performed by COGL and might incur in performance issues.
2553 » Fixed the :load-async and :load-data-async properties of Texture by
2554 removing the unneeded G_PARAM_CONSTRUCT flag.
2556 » Added an initial migration guide that shows the porting process from
2557 older releases of Clutter to the 1.0 API; the first chapter deals with
2558 the migration from ClutterEffect to the new implicit animations API.
2560 » Fixed MT-safety for the master clock.
2564 Ole André Vadla Ravnås
2567 Clutter 0.9.4 (19/06/2009)
2568 ===============================================================================
2570 • List of changes since 0.9.2:
2572 » Set the layout height in ClutterText, so that wrapping and ellipsization
2573 work correctly to fill all the allocated area.
2575 » Remove all the units-based API, and migrate all the positional and
2576 dimensional accessors to use floating point values when dealing with
2577 pixels. All the properties dealing with pixels now that a floating
2578 point value as well.
2580 » Add the ability to track wether an actor is going to be painted or not,
2581 using the "mapped" flag. This also allows Clutter to be more strict
2582 in the handling of the scenegraph, ensuring correctness and avoiding
2583 wasting resources on nodes that won't be painted.
2585 » Add debugging facilities for COGL, similar to those of Clutter; through
2586 them is also possible to have an on screen debugging mode that shows the
2587 boundaries of each rectangle sent to the GPU.
2589 » Rework "units" into real logical distance units that can be converted
2590 between millimeters, typographic points and ems into pixels.
2592 » Simplify the Animation class to avoid redundancy and the possibility
2593 of it going out of sync with the Timeline and Alpha instances it uses.
2595 » Move every operation into a single "master clock" source that advances
2596 the timelines, dispatches events and redraws the stages in a predictable
2597 sequence, thus avoiding unneeded redraws. The default is to follow the
2598 sync-to-vblank cycle, if it is supported by the drivers.
2600 » Cache the glyphs geometry into a vertex buffer object to avoid
2601 resubmitting too much information to the GPU.
2603 » Rework the behaviour of ClutterModel when a filter is applied.
2605 » Allow submitting premultiplied texture data; this removes the need
2606 for unpremultiplying data in CairoTexture.
2608 » Add a simple API for submitting blending and texture combining modes
2609 through a string description.
2611 » Move Timelines to pure time-based objects.
2613 » Lots of performance improvements.
2615 » Removal of all the deprecated API.
2617 » Removal of all the fixed point entry points.
2619 » Lots of documentation fixes - the coverage is now 99% of the exported
2620 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
2622 » Generate the GObject Introspection data for both Clutter and COGL
2625 » Build environment fixes.

2904 Clutter 0.9.0 (30/01/2009)
2905 ===============================================================================
2907 • List of changes between 0.8.6 and 0.9.0
2909 » ClutterText is a new actor allowing text display, text editing
2910 both in multi-line and single-line modes, and text selection using
2911 the pointer devices and the keyboard. ClutterText supercedes both
2912 ClutterLabel and ClutterEntry.
2913 » ClutterClone is a new actor that allows cloning of other actors,
2914 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
2915 » ClutterBindingPool is a new API that allows to easily add key bindings
2917 » ClutterAnimation is a new API for implicit animations, similar to
2918 the tweening API used in toolkits like jQuery, Tween and Flash. This
2919 new API supercedes the ClutterEffect API.
2920 » ClutterAlpha uses "animation modes" instead of raw function
2921 pointers; it is still possible to pass alpha functions. The alpha
2922 functions provided by Clutter have been removed from the public
2923 API. It is possible to register global alpha functions and use
2924 them though a logical id.
2925 » The interval of the ClutterAlpha:alpha property has been changed
2926 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
2927 the addition of "overshooting" easing modes.
2928 » COGL now supports backface culling.
2929 » The COGL-based Pango renderer is public API and it is accessible
2930 to developers. It is also possible to access the PangoContext used
2931 by Clutter in order to create PangoLayouts to render text.
2932 » The ClutterFixed API has been moved to COGL.
2933 » COGL does not depend on Clutter data types anymore.
2934 » The ClutterMedia interface has been overhauled: implementations
2935 now must only override the interface properties. The ranges of
2936 some properties have been changed to normalized values.
2937 » COGL now exposes only floating point entry points, and reserves
2938 the eventual conversion to fixed point only when needed. The
2939 fixed point type and macros are publicly available for developers
2940 concerned about floating point operations.
2941 » COGL has a new Vertex Attribues API that allows submitting an
2942 extensible number of vertex attributes to OpenGL in a way that
2943 does not require format conversions and allows fast re-use.
2944 » COGL has a new Material API that decouples paths from fills; it
2945 is possible to create an arbitrary path and fill it with a COGL
2946 texture. The Material API also allows setting multiple texture
2947 layers and defining the blend modes and colors.
2948 » ClutterTexture has the ability to use a worker thread to asynchronously
2949 load an image from a file, as long as the GLib threading support has
2950 been enabled prior to calling clutter_init().
2951 » Clutter now supports localization of the help output, and it
2952 also supports globally setting the text direction for non left to
2954 » ClutterCairoTexture is a new actor that allows using Cairo
2955 to draw on a ClutterTexture; since Cairo does not have an OpenGL
2956 backend, the drawing is not hardware accelerated.
2957 » Clutter has a unit testing suite, based on the GLib unit test
2958 framework, which can be used to track regressions.
2959 » A ClutterPath object has been added, and it is used by the
2960 BehaviourPath. The Path object allows defining paths using a set
2961 of coordinates and operations. A Path can be "painted" either using
2962 COGL primitives or using Cairo primitives, allowing an easier way
2963 to paint non-rectangular shaped actors.
2964 » ClutterInterval is a simple object, used by ClutterAnimation, that
2965 describes an interval between two values, and interpolates between
2966 the initial and final values of the interval.

3201 Clutter 0.7.2 (23/06/2008), "Kedoke"
3202 ===============================================================================
3204 • List of changes between 0.7.0 and 0.7.2
3206 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
3207 to TRUE the texture will return a preferred width maintaining the
3208 aspect ratio with the given height and a preferred height maintaining
3209 the aspect ratio with the given width. This allows to set the width or
3210 the height and have the texture automatically request the height or the
3211 width respectively while maintaining the aspect ratio of the original
3214 » Added XINPUT support on the X11 backends; this provides an initial
3215 support for multiple input devices. The API is X11-specific, and
3216 provides support for querying at run-time support for XINPUT, for
3217 getting a list of input devices and for getting the type of each
3220 » The 'fruity' backend also features multiple device support.

3238 Clutter 0.7.0 (13/06/2008), "Booska"
3239 ===============================================================================
3241 • List of changes between 0.6 and 0.7.0
3243 » COGL, the underlying GL abstraction layer in Clutter, has been
3244 completely rewritten from the ground up. Its no longer a conceptual
3245 hack but a documented, fully featured library pretty much in its
3246 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
3247 OpenGL ES 2.0, providing a smart uniform API over these libraries
3248 with various utility features such as texture tiling abstractions,
3249 paths and primitive rendering, FBO, shaders, etc.
3251 » Clutter now provides an experimental backend for the Apple(tm)
3252 iPhone and iPod Touch families of products.
3254 » The Windows platform is now natively supported instead of
3255 relying on the SDL libraries. The win32 backend is still
3258 » The X11 based backends now feature support for Actors that wrap
3259 external X drawables (i.e the texture-from-pixmap extension and
3262 » Clutter now seamlessly supports multiple stages on the backends
3263 that allow this feature.
3265 » The custom Pango renderer has been completely rewritten, now using
3266 the more modern and maintained PangoCairo (instead of FT2), and avoids
3267 nasty subclassing hacks, supports smooth fast scaling of text, has
3268 many edge case issues fixed and it still is very efficient (using
3269 a texture glyph cache). It is even a little bit faster.
3271 » Better texture support, timeline improvements, ClutterLabel and
3272 ClutterEntry improvements, and container child properties are among
3273 the new features - too many to fit in the NEWS file.
3277 » #358 - "window resizing doesn't show scaled stage"

3349 Clutter 0.6.0 (18/02/2008)
3350 ==========================
3352 • List of changes between 0.5.6 and 0.6.0
3354 » New documentation sections inside the API reference, describing
3355 the animation framework.

3368 Clutter 0.5.6 (11/02/2008)
3369 ==========================
3371 • List of changes between 0.5.4 and 0.5.6
3373 » Reverted a last minute change in the depth sorting function of
3376 » Added the clutter_actor_move_anchor_point() family of functions,
3377 which will set the anchor point at the given coordinates while
3378 adjusting the actor postion so that the relative position of the
3379 actor toward its parent remains the same.
3381 » Provide a fallback for finding the Clutter alpha functions inside
3382 a UI definition for ClutterScript in case g_module_open() fails.
3384 » Add initial Frame Buffer Objects support in ClutterTexture; using
3385 FBOs, where supported by the hardware and drivers, it's possible to
3386 create a ClutterTexture from any actor.
3388 • List of bugs fixed

3418 Clutter 0.5.4 (25/01/2008)
3419 ==========================
3421 • List of changes between 0.5.2 and 0.5.4
3423 » A clutter-x11-<major>.<minor> pkg-config file is installed along
3424 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
3425 ones, for libraries and applications depending on the X11-based
3426 backends (GLX and EGLX).
3428 » Textures are correctly unrealized before changing and freeing the
3431 » It is now possible to block the automatic call to clutter_main_quit()
3432 when closing the stage window using the frame controls by connecting
3433 an handler for the ::event signal on the Clutter stage and checking
3434 for the CLUTTER_DELETE event type and returning TRUE. This allows
3435 the usage of other main loops with GLib reactors (like Python's twisted)
3436 with Clutter without triggering assertions by closing the stage window.
3438 • List of bugs fixed
3440 » #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]

3457 Clutter 0.5.2 (14/01/2008)
3458 ==========================
3460 • List of changes between 0.5.0 and 0.5.2
3462 » ClutterModelDefault has been renamed to ClutterListModel
3464 » ClutterModel now has vector-based variants for append, prepend and
3465 insert methods; these methods are useful for bindings
3467 » Add units-based variant for clutter_actor_move_by()
3469 • List of bugs fixed
3471 » #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
3472 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
3474 Clutter 0.5.0 (02/01/2008)
3475 ==========================
3477 • List of changes between 0.4.2 and 0.5.0
3479 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
3480 flag set will receive events from the underlying backend; the event
3481 propagation chain will be walked in two directions (from the actor to
3482 the top-level container and back) with the ability to block it in
3485 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
3487 » ClutterScore, an object for controlling timelines; using a score
3488 instance is possible to start multiple timelines at once, or start
3489 a timeline after another has emitted the ::complete signal.
3491 » ClutterScript, an object for parsing a scene from an external file or
3492 a buffer; the scene is described using JSON (JavaScript Object Notation):
3493 every object is defined using its class and properties, and container
3494 objects can have their children defined as well. It is also possible
3495 do describe top-level objects such as timelines and behaviours, and to
3496 automatically connect signal handlers to signal names.
3498 » ClutterTimelines duration can now be set in milliseconds using the
3499 :duration property; the default framerate will be used to compute the
3500 actual duration in frames. The default framerate will be set by the
3501 backend, and can be overridden by the application.
3503 » ClutterTimelines direction can now be set using the :direction
3504 property; a timeline can be set to proceed forward or backward,
3505 and the direction can also be change while the timeline is still
3508 » New, experimental OSX backend.
3510 » Build environment for MS VisualStudio 2005.
3512 » ClutterModel, a generic list-based model object that can be used to
3513 implement actors following the Model-Viewer-Controller design pattern.
3514 Clutter provides a default implementation of ClutterModel, called
3515 ClutterModelDefault and using the GSequence data structure from GLib
3516 to optimize insertion and look up.
3518 » Add the ability to grab pointer and keyboard events: if an actor
3519 is set to have a grab it'll be the only one receiving events until
3520 it releases the grab.
3522 » Add the ability for an actor to receive the key focus; an actor
3523 with key focus will always receive the key events, even if it did
3524 not acquire the keyboard grab.
3526 » It is now possible to set the GL "fog" (also known as "depth cueing")
3527 effect on the ClutterStage; if the fog is enabled, actors farther
3528 away from the view point will fade into the stage background color.
3530 » Each actor now has an "anchor point", a point defined in the actor's
3531 coordinate space that will be used as the origin when scaling and
3532 rotation transformations.
3534 » Every pixel-based API has been doubled with a corresponding
3535 ClutterUnits-based function (postfixed with a '-u'), for instance:
3537 clutter_actor_set_position() - clutter_actor_set_positionu()
3538 clutter_actor_set_size() - clutter_actor_set_sizeu()
3539 clutter_actor_set_depth() - clutter_actor_set_depthu()
3541 This allows sub-pixel precision and device independence.
3543 » The ClutterLabel actor now tries very hard to provide a sane
3544 default size, if no bounding box has been requested; this fixes
3545 the :alignment property and allows the addition of the :justify
3548 » The SDL backend can now be compiled under win32 with MingW; this
3549 backend is still marked as experimental.
3551 » The OSX backend allows the compilation of Clutter under OS X; this
3552 backend is experimental.

3700 Clutter 0.3 (29/06/2007)
3701 ========================
3703 • List of changes between 0.2.3 and 0.3
3704 » Clutter now supports both switchable windowing system and GL backends.
3705 Window systems supported include GLX, EGL and SDL.
3707 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
3708 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
3709 yet documented - usage external to Clutter is not yet advised.
3711 Backends may provide specific command line options.
3717 The GLX backend is built by default and is currently the most
3718 developed, supported and featured windowing system backend. Only
3719 OpenGL is supported via GLX.
3723 Clutter has experimental support for using SDL. Open GL is supported as
3724 is OpenGL ES via Dogles (very experimental).
3728 Clutter has experimental support for using EGL. Only Open GL ES
3729 is supported by EGL.
3731 EGL support assumes an EGL implementation running atop X Windows.
3736 Clutter now has experimental support for Open GL ES.
3737 Current known issues;
3739 + Unrealising a ClutterTexture will not move pixel data from video
3740 into system memory but simply destroy it.
3741 + BGRA, YUV Texture data not currently supported.
3743 (Use the clutter_feature API to probe for above at runtime)
3745 Open Source ES implementations this has been tested against
3746 include `Vincent' and `dgles'. Support for commerical
3747 implementations may require modifications to the configure.ac

3813 » #215 - macro CLUTTER_MARK() not disabled for non-debug builds
3815 Clutter 0.2 (18-01-2007)
3816 ========================
3818 • List of changes between 0.2 and 0.1
3819 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
3820 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
3821 » Actors now have an initial floating reference; this means you
3822 don't have to explicitely unref them: every memory an actor
3823 allocates will be freed when the group containing the actor will
3825 » Add basic run-time detection of GL features.
3826 + Use GL_TEXTURE_RECTANGLE_ARB if available.
3827 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
3828 » Add API for behaviours. A ClutterBehaviour is an object which
3829 drives a set of actors using one or more properties depending
3830 on the value of an "alpha" function.
3831 + Provide simple behaviours: ClutterBehaviourOpacity,
3832 ClutterBehaviourPath and ClutterBehaviourScale.
3833 + Provide simple alpha functions for ramps and sine waveforms.
3834 » Add fixed point API for embedded platforms with no FPU.
3835 » Add support for command line switches to Clutter, like debug
3836 flags and abort on warnings; also allow application to hook up
3837 into the initialisation sequence to add their own command line
3839 » Add Pango GL renderer for Clutter, and use it to render text
3840 inside the ClutterLabel actor; this decrease texture memory
3842 » Redo Clutter Label widget, using the new Pango renderer.
3843 » Clutter Textures do not store local pixbuf copy (of texture).
3844 » Redo group and actor scale/sizing API and functionality.
3845 » Add memory management API for ClutterColor, and string parsing.
3847 » #199 - Little group handling fix?
3848 » #198 - Detect NPOT support on more systems
3849 » #197 - Tiled textures are broken
3850 » #196 - Rebuild the examples when the library changes
3851 » #156 - clutter_actor_set_position not using the absolute size
3852 » #155 - Don't test for XInitThreads [Bastien Nocera]
3853 » #154 - Key presses not working in super-oh example [Bastien Nocera]
3854 » #152 - Misc fixes [Bastien Nocera]
3855 » #143 - Faulty ref-counting in clutter_group_remove [Frederic Riss]
3856 » #141 - Copy-pasto in clutter_media_set_volume [Frederic Riss]
3857 » #101 - No package 'x11' found -- wrong configure [Tomasz Torcz]
3858 » #98 - Enabling trails in super-oh crashes
3860 Clutter 0.1 (22/06/2006)
3861 ========================
3863 • First 'official' release, expect bugs aplenty.
3865 » Hopefully enough functionality to build things.
3866 » Basic gstreamer 0.10 video playback support.
3867 » Fairly stable API, though in no way totally stable.
3868 Expect CHANGES in future versions.
3869 » Some simple examples ( also see OPT ).
3870 » An experimental GTK-Clutter widget.
3871 » Fairly complete Python bindings.
3872 » Non complete but hopefully useful API documentation.
