29 • List of changes since Clutter 1.10.0
31 - Fix expansion of actors inside a TableLayout
32 For actors that span more than one column, the wrong flag was being
33 used to compute the expansion.
35 - Fix text length passed to ClutterTextBuffer
36 This should fix crashers happening when changing the contents of a
37 TextBuffer with non-ASCII characters.
39 - Clean up handling of in-flight changes during implicit transitions
40 The transitions are updated using the new value, as well as the
41 current easing state. The documentation has been updated to define
42 the behaviour of the implicit animations.

58 Clutter 1.10.0 2012-03-22
59 ===============================================================================
61 • Clutter 1.10.0, new stable release
63 • List of changes since Clutter 1.9.16
65 - Fix ClutterTimeline:current-repeat accessor
66 The :current-repeat value was being incremented prior to emitting the
67 completed signal, which meant that signal handlers would not be able
68 to retrieve the correct value.
70 - Improve the memory management of Transitions
71 ClutterActor now takes a reference on the Transitions that have been
72 added to it, and releases the reference when the Transition is removed;
73 this means that it's safe to release the reference of a transition after
74 adding it, to let ClutterActor own it.
76 - Remove the Animatable argument for PropertyTransition constructor
77 The animatable was not meant to be there in the first place; the
78 PropertyTransition will perform validation on the property lazily, once
79 it's been attached to the actor.
81 - Clean up documentation and examples
82 Ensure that the API reference is using the correct API and best
85 - Fix TableLayout policy for actors spanning multiple rows or columns
86 The ClutterTableLayout inherited some small bug from MxTable that got
87 fixed in the meantime; the layout policy has been re-synchronized.
89 - Build fixes for the Wayland backend.
91 - Updated VisualStudio project files.

103 Clutter 1.9.16 2012-03-19
104 ===============================================================================
106 • Clutter 1.10.0, release-candidate 1
108 • List of changes since Clutter 1.9.14
110 - Support implicit animatable properties
111 Various properties of ClutterActor can now be implicitly animated when
112 using the public setters, instead of going through the animation API;
113 this is an opt-in mechanism for the 1.x API series.
115 - Introduce paint nodes
116 ClutterPaintNode is an element of the render tree; it is used to store
117 the pipeline state and the geometry to be drawn. Actors have the ability
118 to be painted using the paint nodes by overriding the paint_node() virtual
119 function instead of the paint() virtual function. For the 1.x API series
120 the render tree will be consumed per-actor, but the plan is to build a
121 full tree as the authoritative source for the 2.x API series.
123 - Support Content delegates
124 ClutterContent is an interface that allows creating classes that will
125 painted in place of an actor's paint() virtual function. Clutter provides
126 two content types: Canvas, a Cairo-based immediate canvas for drawing the
127 contents of an actor; and Image, a content that will paint image data.
129 - ClutterText improvements
130 The caret of editable text actors is now centered, and the background
131 color will be respected when painting the actor.
133 - Support for the XInput 2.2 extension
134 Clutter will now relay touch events coming from the X server, as well
135 as precise scrolling delta, for devices with those two capabilities.
136 The support is still experimental, and limited to the X11 platform for

167 Clutter 1.9.14 2012-03-05
168 ===============================================================================
170 • List of changes since Clutter 1.9.12
172 - Support custom versioning boundaries for the API
173 Now that GLib provides macros for changing the minimum required and
174 maximum allowed version of a library, Clutter can respect the
175 boundaries expressed using CLUTTER_VERSION_MIN_REQUIRED and
176 CLUTTER_VERSION_MAX_ALLOWED.
178 - Add version information to deprecations
180 - Move all deprecated symbols to separate header files
182 - Documentation and annotation fixes.
184 - Accessibility fixes in Cally
185 Do not use ClutterActor:name as the accessible name, and do not
186 provide the extents of an accessible object if the actor to which
187 it refers is not on screen.
189 - Updates to the Wayland compositor and client support
190 Clutter now allows being used for creating hybrid Wayland/X11
191 compositors, working with KMS and evdev directly.
193 - Translation updates: Bulgarian, Ukranian, Galician, Uyghur, Belarusian,

209 Clutter 1.9.12 2012-02-23
210 ===============================================================================
212 • List of changes since Clutter 1.9.10
214 - Add ClutterTimeline:repeat-count and deprecate :loop
215 The :repeat-count property supercedes the :loop property, and it
216 provides a way to specify the number of repeats that a timeline
217 should perform - with the option of specifying an "infinity" value.
219 - Add a progress mode for ClutterTimeline
220 This begins the "soft deprecation" of ClutterAlpha. Instead of
221 requiring a full object to compute an easing function out of a
222 linear progress coming from ClutterTimeline, we should have this
223 functionality on ClutterTimeline itself. Since ClutterAlpha is
224 still exposed in API that we cannot deprecate (such as virtual
225 functions) we cannot deprecate it fully, and we'll have to wait
226 until the 2.0 API bump to get rid of it.
228 - Fix ClutterBoxLayout allocation
229 Since the update of the box layout algorithm there have been a
230 bunch of regressions; now the layout works as intended.
232 - Improve the performance of the shader-based effect in Clutter
233 The effects shipped with Clutter now use the CoglSnippet API
234 internally, which allows efficient generation of the shader code;
235 they also ensure that the shader is generated once per class, and
236 shared across instances. These changes should improve performance
237 when using effects provided by Clutter.
239 - Update the internal usage of Cogl API
240 Clutter should strive to use the Cogl 2.0 API internally and not
241 mix the 1.0 and 2.0 API.
243 - Allow accessing Wayland input devices
244 This is a change that allows Clutter-based toolkits to interact
245 with Wayland in a meaningful way for operations like resize and
248 - Add a convenience CLUTTER_BIND_ALL enumeration
249 This allows binding both position and size of an actor when using
250 a ClutterBindConstraint.
253 Use the newly added API to reimplement focus tracking.
255 - Visual Studio project updates
257 - Add clutter_text_coords_to_position()
258 This method roundtrips the position_to_coords() one, and allows
259 retrieving the index of the character at the given actor-relative
262 - Documentation updates.
264 - Introspection annotation fixes.

280 ===============================================================================
282 • List of changes since Clutter 1.9.8
284 - Provide symbolic names for pointer buttons
285 The primary, middle, and secondary pointer buttons now have simple and
286 easy to remember constants that can be used in place of the "magic"
289 - Add ClutterActorIter
290 A simple API, using a stack allocated opaque structure, for safely and
291 efficiently traverse the children of a ClutterActor.
293 - Fix regression introduced by the default FixedLayout layout manager
294 Existing ClutterActor subclasses using their own layout management should
295 now work exactly like in Clutter 1.8.
297 - Documentation fixes
298 Including introspection annotations fixes.
300 - Updates to the Wayland backend
301 The Wayland client backend is now up to date with the 0.85 release of
302 the Wayland protocol.
304 • Bugs fixed since Clutter 1.9.8

321 • List of changes since Clutter 1.9.6
323 - Fix regressions in users of deprecated API
324 Also, allow to mix the new Actor API with the old Container API without
327 - Add GResource support in ClutterScript
328 GResource is a new infrastructure in GIO that allows to compile resources
329 like UI builder files and image data into a shared library or an
330 executable. A newly added method to ClutterScript makes it possible to
331 load a UI definition from a resource, like it's done for files and
334 - Update the Wayland client backend
335 The SHM transport API has changed upstream, and the Clutter backend has
336 been updated to reflect it.

342 Clutter 1.9.6 2012-01-19
343 ===============================================================================
345 • List of changes since Clutter 1.9.4
347 - Deprecate clutter_actor_show_all() and clutter_actor_hide_all()
348 The latter never did make a lot of sense: hiding the parent will
349 effectively hide the children as well; the former was there only for
350 convenience, but Actors are visible by default.
352 - Gracefully handle existing code
353 The changes in ClutterActor introduced regressions in existing code
354 because of the new functionaly that was introduced to replace deprecated
355 classes like Box and Group. These regressions have hopefully been fixed;
356 Clutter 1.9.6 has been tested with a project as complex as the GNOME
359 - Fix build with binutils-gold
360 The private dependencies were not used when building Clutter, and this
361 made the Gold linker angry.
363 - Allow tracking of an actor's first and last child
364 ClutterActor has two new properties, :first-child and :last-child; these
365 are read-only properties that can be used by toolkits based on Clutter
366 to track the first and last child whenever they change.
368 - Bump the Cogl dependency
369 The 1.9.4 release depended on Cogl ≥ 1.9.4, but the minimum required
370 version was not bumped along with the changes.
372 • List of bugs fixed since Clutter 1.9.4
375 #668137 - FTBFS: pangoft2 check seems to be broken
377 Clutter 1.9.4 2012-01-17
378 ===============================================================================
380 • List of changes since Clutter 1.9.2
382 - New scene graph API in ClutterActor
383 ClutterActor now provides the API for adding, removing, and iterating
384 over the list of children; this deprecates most of the ClutterContainer
385 API. ClutterActor implements ClutterContainer as well, which means that
386 all actors can be containers.
388 - Layout management updates
389 ClutterActor now have an horizontal and vertical alignment properties
390 that will be used when added to a parent; a margin has also been added
391 to the ClutterActor class. Both margin and alignment will be automatically
392 managed during the allocation, so they will work out of the box. It is
393 also possible to set a ClutterLayoutManager delegate object on any
394 ClutterActor instance: the LayoutManager will take care of the layout
395 policy for the children of an actor.
397 - Add ClutterTextBuffer
398 The ClutterTextBuffer class provides a storage for the contents of
399 a ClutterText actor; the same instance can be shared across different
400 actors as well. The main use for ClutterTextBuffer is implementing
401 secure memory storage for the contents of a ClutterText in password
405 ClutterGroup, ClutterBox, and ClutterRectangle have been deprecated; their
406 functionality is now available directly in ClutterActor. The old child
407 actor management API in ClutterActor and ClutterContainer has been
408 deprecated as well. Other deprecations include the ClutterStage
409 fog-related properties and API; the ClutterContainer.sort_depth_order(),
410 raise(), and lower() virtual functions; the internal child push and
411 pop methods on ClutterActor.
413 - ClutterTimeline can parse markers from ClutterScript
414 Markers can now be defined inside ClutterScript, and a ClutterTimeline
415 will be able to automatically add them from a UI definition.
417 - Add a diagnostic mode
418 Similar to the GLib diagnostic mode, Clutter now supports an environment
419 variable that will print out diagnostic messages for deprecations and
420 warnings that can only be detected at run-time.
422 - Wayland backend updates
423 The wayland backend now tracks the latest API changes in the client API,
424 and Clutter now provides a Wayland surface actor that allows to write
425 Wayland compositors, similarly to the X11TexturePixmap actor for the
428 • List of bugs fixed since Clutter 1.9.2
431 #665040 - The offscreen effect always recreates the texture if
432 create_texture() is overridden to change the size
433 #665052 - The internal effects should queue a repaint on the effect not
434 on the actor when a property changes

451 Clutter 1.9.2 2011-11-22
452 ===============================================================================
454 • List of changes since Clutter 1.8
456 - Multi-backend build, and run-time backend selection
457 Clutter can be built with support for multiple backends in the same
458 shared library; the backend singleton is determined at run-time,
459 either with the default backend for the platform, or using the value
460 of the CLUTTER_BACKEND environment variable.
462 - GDK windowing system backend
463 A new backend has been added, which uses the GDK API for creating the
464 drawing surface, as well as receiving the windowing system and input
467 - Show a hint when ClutterText is in password mode
468 If the password-hint-time ClutterSettings property is set to a non
469 zero value, the last character entered inside a ClutterText actor when
470 in password mode will be shown in plain for the duration of the timeout,
471 before being replaced by the glyph chosen as the password character.
473 - Improve Windows build support
474 Clutter now provides project files to build the library using Visual
475 Studio 9 and Visual Studio 10. Also, the scripts to build Clutter using
476 MinGW have been improved.
478 - Remove the requirement for using clutter_threads_init()
479 Threads are initialized by default (depending on the platform), so there
480 is no need to call clutter_threads_init().
482 - Deprecate the default ClutterStage
483 The semantics of the default Stage were not obvious, and had the tendency
486 - Move the deprecated headers into their own directory
487 This should help developers identify the deprecated API.
489 - Change deprecation policy
490 Deprecated functions are now marked using compiler annotations, instead
491 of being forcibly disabled through pre-processor directives from the
492 headers. Deprecations will cause compiler warnings, and thus are enabled
493 by default. If you're building your project with compiler flags that
494 consider every warning a fatal error, you can use the symbol
495 CLUTTER_DISABLE_DEPRECATION_WARNINGS to disable the deprecation warnings.
497 - Translation updates

548 ===============================================================================
550 • List of changes since Clutter 1.7.14
552 - Make sure that setting :use-markup does not depend on the order
553 Setting the :use-markup property should yield the same results regardless
554 of whether the :text property is also set before or after. This applies to
555 ClutterText defined using ClutterScript as well.
557 - Protect against multiple unrealize call on ClutterStage
558 This should fix a segmentation fault in clutter-gtk when unrealize() is
559 called multiple times on an already unrealized stage.
561 - Fortify ATK event listener
562 Make sure that we subscribe only to the events we want to, and avoid
563 warnings caused by AT-SPI, as well as a leak.

590 Clutter 1.7.14 2011-09-05
591 ===============================================================================
593 • List of changes since Clutter 1.7.12
595 - Use newer version of ATK
596 Cally now depends on the latest version of ATK, to reduce the amount of
597 ad hoc code needed and to use newer features that simplify the
598 implementation of accessible objects in Clutter.
600 - Allow using Layout Managers with generic containers
601 Layout managers should not assume that they are allocating the whole
602 area available from the Actor using them; this allows actors that
603 support concepts like padding or margin to use a LayoutManager internally
607 Add a recipe on how to bind a ClutterState to the signals of objects
608 defined in ClutterScript. We also install the cookbook examples inside
609 the $datadir/clutter-1.0/cookbook/examples directory.
611 - Improve examples in the API reference
612 Some of the interactive test suite units are actually good examples of
613 how to use the Clutter API; we can use the XInclude tags to include the
614 source code inside the API reference.
616 - Ensure thread safety of the repaint functions add/removal
617 Fix a long standing issue where adding or removing repaint functions
618 was not acquiring a lock; now it's safe to manipulate the repaint

621 - Make the ClutterText:line-wrap property work again
622 In 1.2 the :line-wrap property was broken, and ClutterText would paint
623 a PangoLayout wrapping until it fit the height of the allocation
624 regardless of whether the :line-wrap property was set to FALSE or
625 TRUE. Now we clip the PangoLayout before rendering it, if the :line-wrap
626 property is set to FALSE and there is no ellipsization policy set.
628 - Disable redirection to offscreen buffer by default
629 Whenever a ClutterActor with children was not fully opaque, the actor
630 was redirected to an FBO, to perform correct opacity computations.
631 Sadly, this can lead to 3x slowdowns, given the amount of framebuffer
632 objects created and the state changes that have to be performed. We
633 decided to turn off this feature by default, to avoid the performance
634 hit. It is still possible to enable this feature on a per-actor basis,
635 though, and will work to reduce the hit in future versions of Cogl,
636 Clutter and the drivers.

659 - Reload the font caches on X11 when the user installs a new font
660 Whenever the user installs a new font inside one of the directories that
661 ware being watched by a session daemon, or changes the fontconfig
662 configuration, the toolkits using FontConfig (either directly or indirectly
663 e.g. through Pango, like Clutter) should listen to the Fontconfig/Timestamp
664 XSETTINGS key and release all the font configuration caches. This allows
665 selecting the newly installed fonts without requiring the user to restart
668 - Allow using "font-description" as a ClutterScript alias for "font-name"
669 ClutterText:font-description allows passing a PangoFontDescription
670 directly to a ClutterText; when defining a ClutterText instance inside a
671 ClutterScript file, :font-description should be an alias for :font-name,
672 which takes a string and converts it to a PangoFontDescription.
674 - Make sure that LayoutManager subclasses take the allocation origin
675 into account when allocating the children
676 A LayoutManager should be resilient against allocations with an origin
677 not positioned at (0, 0); this allows actors using a layout manager
678 instance to munge the box and implement things like margin and padding
679 without the layout manager having knowledge of those concepts.
682 Always link against libm when building Clutter (and its tests); don't
683 rely on libraries lower on the stack to do so.

724 • List of changes since Clutter 1.7.6
726 - Various fixes in Cally
727 Make sure to use Clutter's API and remove old workarounds that were put
728 into place when Cally was a separate project and targeting pre-1.0 API
731 - Add ClutterCairoTexture:auto-resize
732 This property makes it easier to create 2D canvas surfaces by tracking
733 the actor's allocation in a backward compatible way.
735 - Add ClutterAnimatable.interpolate_value()
736 This new virtual function deprecates the animate_property() virtual of the
737 Animatable interface, which was sub-optimal in different ways.
739 - Allow using Animatable implementations with ClutterState
740 Thanks to the new interpolate_value() virtual it is now possible to use
741 the Animatable interface with ClutterState; this allows animating
742 action, constraint and effect properties using the same "@" syntax also
743 used by ClutterAnimation and clutter_actor_animate().
745 - Improve ClutterModel's implementation
746 Avoid a bunch of needless checks, and make sure that the ::row-changed
747 signal is emitted in all cases when a row has been changed through the
748 ClutterModelIter API. The conformance test unit for ClutterModel has
749 also been improved to avoid future regressions.
751 - Improve ClutterStage behaviour on OS X
752 Make sure that the fullscreen, multi-screen and key focusing are
753 well-behaved on OS X, by implementing the correct delegate methods.

783 - Depend on the new Cogl windowing system API.
785 - Add functions for retrieving the clip boundaries on the Stage
786 The clutter_stage_get_redraw_clip_bounds() function is useful for
787 window managers (like Mutter) that need to retrieve the clipped
788 region used on the Stage.
790 - Auto-detect the default flavour when building
791 The default flavour used when building should be set depending
794 - Mark the OSX backend as non-experimental
795 The OSX backend is being developed, and maintained, so it should
796 not be considered experimental.
798 - Make sure that Gestures are cancelled when missing release events
800 - Correct the rounding for paint volumes
801 Try to provide stable results against potential floating point rounding
802 margins when projecting 3D paint volumes into screen bounding boxes;
803 this should avoid re-creating FBOs and always correctly handle clipped
806 - Do not clobber XI2 events data

851 - Unify the GLX and EGL backends to be a single code base
852 The GLX and EGL backends shared most of their code, and with the split
853 out Cogl, we can unify the code base into a single backend. The API as
854 well as the ABI are preserved.
856 - Restore a wider range of Z values for actors
857 The computation for the near and far planes given the perspective
858 transformation used to set up the viewport was broken in 1.7.2, and
859 the distance from the focal point was greatly reduced. This has now
862 - Bump up the dependency of Cogl
863 New windowing system API in Cogl required bumping the minimum version
864 to the latest development snapshot, 1.7.2.
866 - Add ClutterDropAction
867 The ClutterDropAction is an action for allowing ClutterActors to react
868 when an actor being dragged through ClutterDragAction crosses, or is
871 - Add a performance test suite
872 This suite is an addition to our conformance and interactive test
873 suites; the infrastructure can be used by buildbots and report tools
874 to track performance regressions across various commits.

908 Clutter 1.7.2 2011-06-13
909 ===============================================================================
911 • List of changes since Clutter 1.6.0
913 - Cogl moved out of tree
914 The Clutter OpenGL abstraction library has been moved to a separate
915 repository and can be used as a stand-alone shared library. Clutter
916 has been modified to depend on Cogl's experimental API.
918 - Correctly composite non fully opaque children
919 Non fully opauqe actors with non fully opaque children will automatically
920 redirect children paint operations to offscreen buffers, which allow
921 correct composition taking into account the overall opacity of the scene's
922 sub-graph. The same mechanism can be used to create a paint cache, and
923 paint that cache when the actor or its children do not change, instead of
924 painting the whole sub-graph again.
926 - Allow connecting signals to ClutterState states in ClutterScript
927 When defining a scene using ClutterScript it's possible to directly
928 connect a state inside a ClutterState object (both defined in
929 ClutterScript or in code) to an object's signal, without using an
930 explicit signal handler in the code.
932 - Long-press handling in ClutterClickAction
933 ClutterClickAction will detect a long-press gesture and emit signals
934 to query, activation and cancellation.
936 - Added ClutterGestureAction and ClutterSwipeAction
937 ClutterGestureAction is a generic "pointer gesture" action; it doesn't
938 provide an implementation: it's up to the developer to add the gesture
939 recognition code. ClutterSwipeAction is a GestureAction sub-class that
940 implement the "swipe" gesture. The GestureAction API is already future
941 proof for multi-device/multi-touch, even though the multi-touch isn't
942 currently implemented.
944 - Allow Effects to influence picking
945 Effects that change the geometry of a ClutterActor should also be
946 allowed to change the picking code to make sure that event handling
947 keeps working. ClutterEffect has a new pick() virtual function for

1188 API provide access to the same features.
1190 » Be more resilient against timelines controlling the state of
1191 other timelines during the clock tick.
1193 » Provide defines for the windowing platforms, to allow portable
1194 applications to include the correct header and select the
1195 correct API depending on the target.
1197 » Introduce a fast path for cogl_read_pixels() that uses the journal
1198 to determine the position of a single pixel on the stage; this
1199 fast path gracefully degrades to the usual render-based approach,
1200 and should speed up picking considerably in the case of opaque
1201 quads batched together.
1203 » Support XInput axis data on valuator devices, and introduce XInput2
1204 support for event translation and device hotplugging. The support
1205 for XI and XI2 must still be explicitly enabled by the developer,
1206 but it is now compiled in by default. It can be disabled at compile
1207 time by passing --disable-xinput to the configure script.

1373 Clutter 1.5.6 2010-11-19
1374 ===============================================================================
1376 • List of changes since Clutter 1.5.4
1378 » Deprecate ClutterBehaviour and its sub-classes: the same functionality
1379 is available using the animation framework.
1381 » Add ClutterSnapConstraint, a constraint implementation that snaps
1382 together the edges of two actors.
1384 » Add ClutterPathConstraint::node-reached.
1386 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
1387 not used internally any more, and since it's not integrated with
1388 the master clock it's of relative use.
1390 » Add a named, global color palette.
1392 » Add the ClutterTimeline:reverse property, for automatically
1393 reversing the direction of a timeline after the emission of
1394 the ::completed signal.
1396 » Performance improvements in the clip stack.
1398 » Do not use pointer grabs in ClutterClickAction.
1400 » Improve the internally used Cogl API for primitives, paths and

1403 » Allow using the COGL_DEBUG environment variable to disable the
1406 » Plug a nasty infinite loop in the XSETTINGS implementation.
1408 » Internally rename CoglMaterial to CoglPipeline; this should make
1409 it clearer that the API refers to the state of the GPU pipeline.
1411 » Add support for clipped redraws on EGL using the NOK_swap_region
1416 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.

1478 Clutter 1.5.2 (04/10/2010)
1479 ===============================================================================
1481 • List of changes since Clutter 1.4.0
1483 » Add API to ClutterActor to allow any actor to define its 3D paint
1484 volume and its stage-relative 2D bounding box; the paint volume is
1485 the 3D space occupied by an actor during the paint sequence. This
1486 allows better sizing of the FBOs, and opens the door to scenegraph
1487 culling and accurate clipped redraws. The mechanism is opt-in: actors
1488 have to implement the get_paint_volume() virtual function. Callbacks
1489 attached to the ::paint signal will also disable any culling and
1490 clipped redraw in place internally.
1492 » Plug a leak in ClutterActor by disposing all constraints.
1494 » Rework the build system to be as non-recursive as possible; this should
1495 speed up the build of Clutter, and makes the build layout easier to
1496 understand and update.
1498 » Remove the internal copy of JSON-GLib; the internal copy was falling
1499 behind at a spectacular level, and it was actually making the build
1500 rather complicated - also by adding an unwanted, but needed,
1501 introspection data generation. The required JSON-GLib has also been
1502 bumped to the new stable release, 0.12.0.
1504 » Use g_object_install_properties() with GLib 2.26.
1506 » Implement ClutterContainer::child-notify, which slipped through the
1507 cracks of many development cycles without anyone noticing.
1509 » Document and test clutter_actor_contains(), especially the corner
1512 » Plug a leak in CoglTexture2DSliced.
1514 » Plug a leak in ClutterAnimator's handling of timelines.
1516 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
1517 errors when the GLX pixmap is destroyed behind Cogl's back.
1530 Clutter 1.4.0 (24/09/2010)

1578 - reusing complex animations
1580 » Add methods to retrieve the clicked button and to force a release
1583 » Documentation fixes in the API reference.
1585 » Cache a full pick buffer and re-use it in case the scene does not change
1588 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
1590 » Allow detaching animations created with clutter_actor_animate().
1592 » Depend on GObject-Introspection >= 0.9.5.
1594 » Provide introspection data for the X11-specific API, like
1595 ClutterX11TexturePixmap
1597 » Use a template material for ClutterTexture to minimize the creation of

1601 :x-drag-threshold and :y-drag-threshold.
1603 » Allow disabling the -Bsymbolic flag when linking.
1605 » Use gettext >= 0.17 to handle the localization.
1607 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
1608 a crash when dealing with clip stacks.
1610 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
1611 freeing the X11 Pixmap to avoid an error.
1613 » Avoid regenerating the CoglMaterial programs too many times.

1738 » Fix GLES build after the Cogl material changes.
1740 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
1742 » Split the clutter_state_change() method into two:
1743 clutter_state_set_state(), for animated state changes; and
1744 clutter_state_warp_to_state() for immediate state changes.
1746 » Documentation and introspection fixes.
1760 Clutter 1.3.6 (30/06/2010)
1761 ===============================================================================
1763 • List of changes since Clutter 1.3.4
1765 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
1766 available, by using EXT_framebuffer_blit. Both mechanisms are also
1767 throttled to avoid taking all resources when using them in a compositor
1770 » Use (and cache) fragment shaders instead of texture combiners inside
1771 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
1772 to fixed functions depending on the level of support of the underlying
1775 » Implement a new design for materials; this allows scaling up the
1776 number of materials in a scene, and also makes copying materials
1779 » Make Cogl materials responsible for depth testing, and add new
1782 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
1783 object instead of using the stencil buffer, or the scanline rasterizer
1784 on platforms without a stencil buffer.
1786 » Add ClutterDeformEffect, a base class for effects that deform an
1787 actor's geometry when painting it; ClutterPageTurnEffect is an
1788 implementation of a "page curl" deformation using the DeformEffect
1791 » Always use scissoring when clipping, to reduce the amount of buffer
1792 that has to be cleared.
1794 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
1795 a constructor property; the default remains fragment shader.
1797 » Remove the button of the press event from the DragAction::drag-begin
1798 and DragAction::drag-end signals. This is an API break from 1.3.4.
1800 » Do not promote clipped redraws to full redraws.
1802 » Improve the consistency of the default state name in ClutterState,
1803 both in the API and in the serialization format.
1805 » Fix a rounding error with the Text layout size.
1807 » Add utility functions for CoglMatrix and CoglColor.
1809 » Avoid a re-allocation cycle warning when resizing the surface of
1810 a CairoTexture actor from within the allocate() implementation.
1812 » Do not add the GL libraries for the EGL X11 backend.
1814 » Add more checks for size of data passed to the shader types GValue
1817 » Add width and height to the BindConstraint.
1819 » Parse actions, constraints and effects inside an actor definition
1822 » Merge the code of native and x11 backends for EGL into a single
1823 backend; also allow creating GL context with the EGL backend.
1825 » Use XSETTINGS to set up the backend configuration options, like
1826 the font name, resolution, font options and double click options,
1827 on X11; this also allows ClutterText actors created using the
1828 default font name to be updated when the font name and options
1829 change; similarly, this allows ClutterUnits to be updated when
1830 the screen resolution changes.
1832 » Implement the texture_from_pixmap extension support inside Cogl
1833 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
1835 » Documentation improvements in the API reference and in the cookbook.
1837 » Use the -Bsymbolic-functions linker option on supported platforms
1838 to avoid intra-library PLT jumps.
1840 » Fix painting transparent stages on X11 using the :use-alpha property
1843 » Fix emission of scroll events on Windows.
1862 Clutter 1.3.4 (07/06/2010)
1863 ===============================================================================
1865 • List of changes since Clutter 1.3.2
1867 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
1868 way an actor paints itself.
1870 » Clutter provides a base class for effects painting to an
1871 offscreen buffer, and a base class for effects using the
1872 GL programmable pipeline (through the GLSL shader language).
1874 » Clutter also provides some simple, shader-based effects:
1875 ClutterBlurEffect, ClutterColorizeEffect and
1876 ClutterDesaturateEffect.
1878 » Effects can be applied to any actor, and can also be stacked.
1880 » Add ClutterClickAction, an action that provides "button-like"
1881 semantics for any ClutterActor.
1883 » ClutterDragAction now moves the actor to which it has been applied
1884 by default, using a class handler for the ::drag-motion signal.
1886 » Add the :pick-with-alpha property to ClutterTexture; this property
1887 allows using the alpha channel of a texture when picking it.
1889 » Regenerate the mipmaps on COGL textures when a texture is modified.
1891 » Documentation and build fixes.

1912 logic related to sizing and positioning.
1914 » ClutterDragAction is an Action sub-class that implements
1915 signals and properties for dragging actors.
1917 » ClutterAlignConstraint and ClutterBindConstraint are two
1918 Constraint sub-classes that allow relative positioning
1919 with fixed layout managers.
1921 » Add ClutterState, an object for defining state transitions.
1923 » Add ClutterBoxLayout:homogeneous property.

1936 an AtkObject from a ClutterActor.
1938 » Improve ClutterText's Pango layout caching mechanism.
1940 » Fix set up of the GLX_SGI_swap_control extension.

1986 of JSON-GLib to which we fall back in the absence of the system
1989 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
1999 Clutter 1.2.0 (02/03/2010)

2130 » Improve readability of ClutterActor::raise/::lower warnings.
2137 Clutter 1.1.8 (08/02/2010)
2138 ===============================================================================
2140 • List of changes since Clutter 1.1.6
2142 » Added ClutterAnimator, a class that allows defining complex
2143 implicit animations involving multiple actors and states; this
2144 class is mostly meant to be used through the ClutterScript
2145 definition format, but it provides a convenience C API for
2146 easily building animations.
2148 » New experimental COGL API to expose "hardware" buffers such as PBOs or
2149 drm surfaces. This API can be used, for instance, to make texture
2152 » Fixed the issues with resizable stages getting a 1x1 window with

2166 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
2168 » Improve the extendability of CoglTexture with internal backends.
2170 » Add implicit texture atlasing; Cogl will try to put every texture
2171 inside the same texture atlas by default, to avoid state changes
2172 in the driver and (hopefully) improve performance.
2174 » Fix notification of the cursor and selection changes in ClutterText;
2175 this improves the usage of Clutter from A11Y toolkits.
2177 » Do not wait for a frame if the system clock goes backwards.
2179 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
2181 » Documentation and build fixes.
2194 Clutter 1.1.6 (18/01/2010)
2195 ===============================================================================
2197 • List of changes since Clutter 1.1.4
2199 » Some fixes for the Win32 backend (bug #1905).
2201 » Profiling support via the UProf library. Configure with
2202 --enable-profile to get a report after each Clutter application is
2205 » Improved conformance tests with coverage reports via gcov.
2207 » ClutterTexture no longer tries to read back texture data into
2208 g_malloc'd memory on unrealize (bug #1842).
2210 » The CGL_• defines from cogl-defines.h have been removed. These
2211 should not have been used by any applications, but if they were
2212 being used then please replace them either with the Cogl enums or
2213 with the appropriate GL_• enum if you are using GL directly.
2215 » Added a delete-event signal to the stage.
2217 » Fix for using cogl_rectangle with different texture coordinates
2218 for multiple layers (bug #1937).
2220 » Fix for using stencil and depth buffers in FBOs on Intel drivers
2221 in Mesa (bug #1873).
2223 » Support for subtitles in ClutterMedia.
2225 » ClutterGLX will now use an RGB visual by default. For
2226 applications (and toolkit integration libraries) that want to
2227 enable the ClutterStage:use-alpha property there is a new
2228 function: clutter_x11_set_use_argb_visual().
2230 » Fix ClutterText to allow using Pango markup and attributes in
2231 the same actor (bug #1940).
2243 Clutter 1.1.4 (03/01/2010)
2244 ===============================================================================
2246 • List of changes since Clutter 1.1.2
2248 » Update the ClutterScript parser to be more resilient, and support
2249 constructor and ChildMeta properties. The parser also respects the
2250 order of the properties in the UI definitions when applying them,
2251 and will apply the properties of an Actor after building the scene
2254 » Simplified the implementation of LayoutManager sub-classes, and added
2255 support for animating a layout manager.
2257 » Allow short-circuiting some layout operations by setting a specific
2258 flag on ClutterActor.
2260 » Improve caching of the preferred size of a ClutterActor.
2262 » Allow declaring "internal children" for a ClutterContainer
2263 implementation: the memory management of these actors will be deferred
2264 entirely to the Container.
2266 » Let the ClutterStage honour the :opacity property and the alpha component
2267 of the stage color. This requires support in the Clutter backend used.
2269 » Improve Windows and OSX backends.
2271 » Simplify the feature detection code for OpenGL; this also reduced the
2272 required OpenGL version to 1.2.
2274 » Improve the matrix stack handling code. The matrices can be debugged by
2275 using the COGL_DEBUG environment variable, assuming that Clutter was
2276 compiled with the right configure-time switch.
2278 » Improve COGL API for draw buffers, and for offscreen buffer support.
2280 » Add support for text direction to ClutterActor.
2282 » Documentation, introspection and build fixes.
2299 Clutter 1.1.2 (23/10/2009)
2300 ===============================================================================
2302 • List of changes since Clutter 1.0
2304 » Add ClutterLayoutManager, an abstract proxy class for easily
2305 writing layout management policies; also add ClutterLayoutMeta,
2306 a class for storing layout properties.
2308 » Add ClutterBox, a generic container actor that relies on a
2309 ClutterLayoutManager instance to manage the layout of its
2312 » Add the following layout managers:
2314 - ClutterFixedLayout - a layout manager implementing the
2315 policy used by ClutterGroup
2317 - ClutterBinLayout - a layout manager for packing actors
2318 as layers inside the same area, with per-actor alignment
2320 - ClutterFlowLayout - a layout manager arranging actors as
2323 - ClutterBoxLayout - a layout manager arranging actors as
2326 » Remove the requirement for the backend-specific implementation
2327 of ClutterStage to be a ClutterActor: a Stage implementation must
2328 only implement the ClutterStageWindow interface. This cleans up
2331 » COGL source tree clean up and rationalization; COGL now
2332 knows the platform, and not only the driver (GL or GLES) so
2333 we can migrate part of the low-level backend code from Clutter
2334 to COGL where it makes sense.
2336 » Remove code duplication across whole COGL.
2338 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
2339 have been fixed and confirmed working.
2341 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
2342 dumps the contents of each pick() buffer into a PNG file, for
2345 » Allow interpolating intervals of ClutterUnits for animating
2346 unit-based properties.
2348 » Increase strictness and correctness of the ClutterUnits
2351 » Add GValue transformation functions for ClutterPath to and
2354 » Fix word movement in ClutterText; implement GObject getter for
2355 :use-markup; emit notification for :position; decouple the
2356 :text property from the :use-markup property.
2358 » Do not queue redraws or relayouts on actors currently being
2361 » Support #rrggbb and #rgb notations for ClutterColor.
2363 » Multiple bug fixes.
2365 » Provide _NET_WM_PID on the X11 stage implementation.
2367 » Documentation and Introspection annotation fixes.
2369 » Add test units for the ClutterActor size requesition.
2373 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
2374 back to Shave on older Automake versions.
2394 Clutter 1.0.0 (28/07/2009)
2395 ===============================================================================
2397 • List of changes since 0.9.8
2399 » Allow per-stage disabling of motion event throttling; this should allow
2400 platforms or applications that require all the motion events not for
2401 drawing purposes to get them exactly like Clutter gets them from the
2404 » Various documentation fixes.
2406 » Add per-word key navigation inside ClutterText.
2408 » Fix the RGB<->HLS conversion.
2410 » Various fixes for the OSX backend.
2412 » Various build-related fixes.
2420 Clutter 0.9.8 (17/07/2009)
2421 ===============================================================================
2423 • List of changes since 0.9.6
2425 » Add more introspection annotations for language bindings.
2427 » Fix a bug in clutter_animation_set_alpha(), which also broke the
2428 clutter_actor_animate_with_alpha() function.
2430 » Check if the stage requires a relayout before showing it; this fixes
2431 a bug in the X11-based backends, especially under compositing window
2432 managers, where a 640x480 window would flicker before the default
2433 stage was shown for the first time.
2435 » Performance fixes for Cogl.
2437 » Sliced textures were broken by the COGL journalling.
2439 » Use the redraw cycle when asynchronously loading textures from
2442 » Miscellaneous compilation fixes for the OS X and Windows backends.
2444 » Allow querying from within the paint function of an Actor whether
2445 the actor is currently being directly painted or by a Clone actor.
2447 » In the GLX backend, when using the non-implicit sync-to-vblank inside
2448 glXSwapBuffers(), call glFinish() to avoid potential tearing.
2458 Clutter 0.9.6 (01/07/2009)
2459 ===============================================================================
2461 • List of changes since 0.9.4:
2463 » Allow the manipulation of the actor's transformation matrix, so that is
2464 is possible to apply additional transformations in a way that is
2465 compatible with the transformations already applied by the scene graph.
2467 » Fix a race in the X11 backend that happened between resizing the stage
2468 drawable and the call to glViewport().
2470 » Merge the cogl-journal-batching branch; this branch implements batching
2471 the geometry of the elements of the scene graph before sending it to
2472 OpenGL, thus minimizing the number of state changes and improving the
2473 overall performance of Clutter-based applications.
2475 » Add more debugging states for Clutter and COGL, which allow the developer
2476 to track the state of the journal; to check the VBO fallback paths; to
2477 disable picking for reliable profiling; to disable software-side matrix
2478 transformations in favour of the driver/GPU ones.
2480 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
2481 semantics; applications that drop into raw GL are, though, ignoring all
2482 the caching performed by COGL and might incur in performance issues.
2484 » Fixed the :load-async and :load-data-async properties of Texture by
2485 removing the unneeded G_PARAM_CONSTRUCT flag.
2487 » Added an initial migration guide that shows the porting process from
2488 older releases of Clutter to the 1.0 API; the first chapter deals with
2489 the migration from ClutterEffect to the new implicit animations API.
2491 » Fixed MT-safety for the master clock.
2495 Ole André Vadla Ravnås
2498 Clutter 0.9.4 (19/06/2009)
2499 ===============================================================================
2501 • List of changes since 0.9.2:
2503 » Set the layout height in ClutterText, so that wrapping and ellipsization
2504 work correctly to fill all the allocated area.
2506 » Remove all the units-based API, and migrate all the positional and
2507 dimensional accessors to use floating point values when dealing with
2508 pixels. All the properties dealing with pixels now that a floating
2509 point value as well.
2511 » Add the ability to track wether an actor is going to be painted or not,
2512 using the "mapped" flag. This also allows Clutter to be more strict
2513 in the handling of the scenegraph, ensuring correctness and avoiding
2514 wasting resources on nodes that won't be painted.
2516 » Add debugging facilities for COGL, similar to those of Clutter; through
2517 them is also possible to have an on screen debugging mode that shows the
2518 boundaries of each rectangle sent to the GPU.
2520 » Rework "units" into real logical distance units that can be converted
2521 between millimeters, typographic points and ems into pixels.
2523 » Simplify the Animation class to avoid redundancy and the possibility
2524 of it going out of sync with the Timeline and Alpha instances it uses.
2526 » Move every operation into a single "master clock" source that advances
2527 the timelines, dispatches events and redraws the stages in a predictable
2528 sequence, thus avoiding unneeded redraws. The default is to follow the
2529 sync-to-vblank cycle, if it is supported by the drivers.
2531 » Cache the glyphs geometry into a vertex buffer object to avoid
2532 resubmitting too much information to the GPU.
2534 » Rework the behaviour of ClutterModel when a filter is applied.
2536 » Allow submitting premultiplied texture data; this removes the need
2537 for unpremultiplying data in CairoTexture.
2539 » Add a simple API for submitting blending and texture combining modes
2540 through a string description.
2542 » Move Timelines to pure time-based objects.
2544 » Lots of performance improvements.
2546 » Removal of all the deprecated API.
2548 » Removal of all the fixed point entry points.
2550 » Lots of documentation fixes - the coverage is now 99% of the exported
2551 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
2553 » Generate the GObject Introspection data for both Clutter and COGL
2556 » Build environment fixes.

2835 Clutter 0.9.0 (30/01/2009)
2836 ===============================================================================
2838 • List of changes between 0.8.6 and 0.9.0
2840 » ClutterText is a new actor allowing text display, text editing
2841 both in multi-line and single-line modes, and text selection using
2842 the pointer devices and the keyboard. ClutterText supercedes both
2843 ClutterLabel and ClutterEntry.
2844 » ClutterClone is a new actor that allows cloning of other actors,
2845 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
2846 » ClutterBindingPool is a new API that allows to easily add key bindings
2848 » ClutterAnimation is a new API for implicit animations, similar to
2849 the tweening API used in toolkits like jQuery, Tween and Flash. This
2850 new API supercedes the ClutterEffect API.
2851 » ClutterAlpha uses "animation modes" instead of raw function
2852 pointers; it is still possible to pass alpha functions. The alpha
2853 functions provided by Clutter have been removed from the public
2854 API. It is possible to register global alpha functions and use
2855 them though a logical id.
2856 » The interval of the ClutterAlpha:alpha property has been changed
2857 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
2858 the addition of "overshooting" easing modes.
2859 » COGL now supports backface culling.
2860 » The COGL-based Pango renderer is public API and it is accessible
2861 to developers. It is also possible to access the PangoContext used
2862 by Clutter in order to create PangoLayouts to render text.
2863 » The ClutterFixed API has been moved to COGL.
2864 » COGL does not depend on Clutter data types anymore.
2865 » The ClutterMedia interface has been overhauled: implementations
2866 now must only override the interface properties. The ranges of
2867 some properties have been changed to normalized values.
2868 » COGL now exposes only floating point entry points, and reserves
2869 the eventual conversion to fixed point only when needed. The
2870 fixed point type and macros are publicly available for developers
2871 concerned about floating point operations.
2872 » COGL has a new Vertex Attribues API that allows submitting an
2873 extensible number of vertex attributes to OpenGL in a way that
2874 does not require format conversions and allows fast re-use.
2875 » COGL has a new Material API that decouples paths from fills; it
2876 is possible to create an arbitrary path and fill it with a COGL
2877 texture. The Material API also allows setting multiple texture
2878 layers and defining the blend modes and colors.
2879 » ClutterTexture has the ability to use a worker thread to asynchronously
2880 load an image from a file, as long as the GLib threading support has
2881 been enabled prior to calling clutter_init().
2882 » Clutter now supports localization of the help output, and it
2883 also supports globally setting the text direction for non left to
2885 » ClutterCairoTexture is a new actor that allows using Cairo
2886 to draw on a ClutterTexture; since Cairo does not have an OpenGL
2887 backend, the drawing is not hardware accelerated.
2888 » Clutter has a unit testing suite, based on the GLib unit test
2889 framework, which can be used to track regressions.
2890 » A ClutterPath object has been added, and it is used by the
2891 BehaviourPath. The Path object allows defining paths using a set
2892 of coordinates and operations. A Path can be "painted" either using
2893 COGL primitives or using Cairo primitives, allowing an easier way
2894 to paint non-rectangular shaped actors.
2895 » ClutterInterval is a simple object, used by ClutterAnimation, that
2896 describes an interval between two values, and interpolates between
2897 the initial and final values of the interval.

3133 ===============================================================================
3135 • List of changes between 0.7.0 and 0.7.2
3137 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
3138 to TRUE the texture will return a preferred width maintaining the
3139 aspect ratio with the given height and a preferred height maintaining
3140 the aspect ratio with the given width. This allows to set the width or
3141 the height and have the texture automatically request the height or the
3142 width respectively while maintaining the aspect ratio of the original
3145 » Added XINPUT support on the X11 backends; this provides an initial
3146 support for multiple input devices. The API is X11-specific, and
3147 provides support for querying at run-time support for XINPUT, for
3148 getting a list of input devices and for getting the type of each
3151 » The 'fruity' backend also features multiple device support.

3169 Clutter 0.7.0 (13/06/2008), "Booska"
3170 ===============================================================================
3172 • List of changes between 0.6 and 0.7.0
3174 » COGL, the underlying GL abstraction layer in Clutter, has been
3175 completely rewritten from the ground up. Its no longer a conceptual
3176 hack but a documented, fully featured library pretty much in its
3177 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
3178 OpenGL ES 2.0, providing a smart uniform API over these libraries
3179 with various utility features such as texture tiling abstractions,
3180 paths and primitive rendering, FBO, shaders, etc.
3182 » Clutter now provides an experimental backend for the Apple(tm)
3183 iPhone and iPod Touch families of products.
3185 » The Windows platform is now natively supported instead of
3186 relying on the SDL libraries. The win32 backend is still
3189 » The X11 based backends now feature support for Actors that wrap
3190 external X drawables (i.e the texture-from-pixmap extension and
3193 » Clutter now seamlessly supports multiple stages on the backends
3194 that allow this feature.
3196 » The custom Pango renderer has been completely rewritten, now using
3197 the more modern and maintained PangoCairo (instead of FT2), and avoids
3198 nasty subclassing hacks, supports smooth fast scaling of text, has
3199 many edge case issues fixed and it still is very efficient (using
3200 a texture glyph cache). It is even a little bit faster.
3202 » Better texture support, timeline improvements, ClutterLabel and
3203 ClutterEntry improvements, and container child properties are among
3204 the new features - too many to fit in the NEWS file.

3299 Clutter 0.5.6 (11/02/2008)
3300 ==========================
3302 • List of changes between 0.5.4 and 0.5.6
3304 » Reverted a last minute change in the depth sorting function of
3307 » Added the clutter_actor_move_anchor_point() family of functions,
3308 which will set the anchor point at the given coordinates while
3309 adjusting the actor postion so that the relative position of the
3310 actor toward its parent remains the same.
3312 » Provide a fallback for finding the Clutter alpha functions inside
3313 a UI definition for ClutterScript in case g_module_open() fails.
3315 » Add initial Frame Buffer Objects support in ClutterTexture; using
3316 FBOs, where supported by the hardware and drivers, it's possible to
3317 create a ClutterTexture from any actor.
3319 • List of bugs fixed
3321 » #386 - Stage is white unless a timeline is present
3322 » #439 - timing related pong lockup due to timeline rewind...

3349 Clutter 0.5.4 (25/01/2008)
3350 ==========================
3352 • List of changes between 0.5.2 and 0.5.4
3354 » A clutter-x11-<major>.<minor> pkg-config file is installed along
3355 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
3356 ones, for libraries and applications depending on the X11-based
3357 backends (GLX and EGLX).
3359 » Textures are correctly unrealized before changing and freeing the
3362 » It is now possible to block the automatic call to clutter_main_quit()
3363 when closing the stage window using the frame controls by connecting
3364 an handler for the ::event signal on the Clutter stage and checking
3365 for the CLUTTER_DELETE event type and returning TRUE. This allows
3366 the usage of other main loops with GLib reactors (like Python's twisted)
3367 with Clutter without triggering assertions by closing the stage window.
3369 • List of bugs fixed
3371 » #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]

3388 Clutter 0.5.2 (14/01/2008)
3389 ==========================
3391 • List of changes between 0.5.0 and 0.5.2
3393 » ClutterModelDefault has been renamed to ClutterListModel

3400 • List of bugs fixed
3402 » #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
3403 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
3405 Clutter 0.5.0 (02/01/2008)
3406 ==========================
3408 • List of changes between 0.4.2 and 0.5.0
3410 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
3411 flag set will receive events from the underlying backend; the event
3412 propagation chain will be walked in two directions (from the actor to
3413 the top-level container and back) with the ability to block it in
3416 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
3418 » ClutterScore, an object for controlling timelines; using a score
3419 instance is possible to start multiple timelines at once, or start
3420 a timeline after another has emitted the ::complete signal.
3422 » ClutterScript, an object for parsing a scene from an external file or
3423 a buffer; the scene is described using JSON (JavaScript Object Notation):
3424 every object is defined using its class and properties, and container
3425 objects can have their children defined as well. It is also possible
3426 do describe top-level objects such as timelines and behaviours, and to
3427 automatically connect signal handlers to signal names.
3429 » ClutterTimelines duration can now be set in milliseconds using the
3430 :duration property; the default framerate will be used to compute the
3431 actual duration in frames. The default framerate will be set by the
3432 backend, and can be overridden by the application.
3434 » ClutterTimelines direction can now be set using the :direction
3435 property; a timeline can be set to proceed forward or backward,
3436 and the direction can also be change while the timeline is still
3439 » New, experimental OSX backend.
3441 » Build environment for MS VisualStudio 2005.
3443 » ClutterModel, a generic list-based model object that can be used to
3444 implement actors following the Model-Viewer-Controller design pattern.
3445 Clutter provides a default implementation of ClutterModel, called
3446 ClutterModelDefault and using the GSequence data structure from GLib
3447 to optimize insertion and look up.
3449 » Add the ability to grab pointer and keyboard events: if an actor
3450 is set to have a grab it'll be the only one receiving events until
3451 it releases the grab.
3453 » Add the ability for an actor to receive the key focus; an actor
3454 with key focus will always receive the key events, even if it did
3455 not acquire the keyboard grab.
3457 » It is now possible to set the GL "fog" (also known as "depth cueing")
3458 effect on the ClutterStage; if the fog is enabled, actors farther
3459 away from the view point will fade into the stage background color.
3461 » Each actor now has an "anchor point", a point defined in the actor's
3462 coordinate space that will be used as the origin when scaling and
3463 rotation transformations.
3465 » Every pixel-based API has been doubled with a corresponding
3466 ClutterUnits-based function (postfixed with a '-u'), for instance:
3468 clutter_actor_set_position() - clutter_actor_set_positionu()
3469 clutter_actor_set_size() - clutter_actor_set_sizeu()
3470 clutter_actor_set_depth() - clutter_actor_set_depthu()
3472 This allows sub-pixel precision and device independence.
3474 » The ClutterLabel actor now tries very hard to provide a sane
3475 default size, if no bounding box has been requested; this fixes
3476 the :alignment property and allows the addition of the :justify
3479 » The SDL backend can now be compiled under win32 with MingW; this
3480 backend is still marked as experimental.
3482 » The OSX backend allows the compilation of Clutter under OS X; this
3483 backend is experimental.

3632 ========================
3634 • List of changes between 0.2.3 and 0.3
3635 » Clutter now supports both switchable windowing system and GL backends.
3636 Window systems supported include GLX, EGL and SDL.
3638 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
3639 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
3640 yet documented - usage external to Clutter is not yet advised.
3642 Backends may provide specific command line options.
3648 The GLX backend is built by default and is currently the most
3649 developed, supported and featured windowing system backend. Only
3650 OpenGL is supported via GLX.
3654 Clutter has experimental support for using SDL. Open GL is supported as
3655 is OpenGL ES via Dogles (very experimental).
3659 Clutter has experimental support for using EGL. Only Open GL ES
3660 is supported by EGL.
3662 EGL support assumes an EGL implementation running atop X Windows.
3667 Clutter now has experimental support for Open GL ES.
3668 Current known issues;
3670 + Unrealising a ClutterTexture will not move pixel data from video
3671 into system memory but simply destroy it.
3672 + BGRA, YUV Texture data not currently supported.
3674 (Use the clutter_feature API to probe for above at runtime)
3676 Open Source ES implementations this has been tested against
3677 include `Vincent' and `dgles'. Support for commerical
3678 implementations may require modifications to the configure.ac

3682 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
3684 dgles: http://developer.hybrid.fi/dgles/index.html
3686 » New ClutterEffect class provides a simplified (and thus less flexible)
3687 API wrapping around behaviours, alphas and timelines.
3688 » New Behaviours - bspline, ellipsis, rotation.
3689 » New built in Alpha functions;

3746 Clutter 0.2 (18-01-2007)
3747 ========================
3749 • List of changes between 0.2 and 0.1
3750 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
3751 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
3752 » Actors now have an initial floating reference; this means you
3753 don't have to explicitely unref them: every memory an actor
3754 allocates will be freed when the group containing the actor will
3756 » Add basic run-time detection of GL features.
3757 + Use GL_TEXTURE_RECTANGLE_ARB if available.
3758 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
3759 » Add API for behaviours. A ClutterBehaviour is an object which
3760 drives a set of actors using one or more properties depending
3761 on the value of an "alpha" function.
3762 + Provide simple behaviours: ClutterBehaviourOpacity,
3763 ClutterBehaviourPath and ClutterBehaviourScale.
3764 + Provide simple alpha functions for ramps and sine waveforms.
3765 » Add fixed point API for embedded platforms with no FPU.
3766 » Add support for command line switches to Clutter, like debug
3767 flags and abort on warnings; also allow application to hook up
3768 into the initialisation sequence to add their own command line
3770 » Add Pango GL renderer for Clutter, and use it to render text
3771 inside the ClutterLabel actor; this decrease texture memory
3773 » Redo Clutter Label widget, using the new Pango renderer.
3774 » Clutter Textures do not store local pixbuf copy (of texture).
3775 » Redo group and actor scale/sizing API and functionality.
3776 » Add memory management API for ClutterColor, and string parsing.
