231 Clutter 1.3.6 (30/06/2010)
232 ===============================================================================
234 • List of changes since Clutter 1.3.4
236 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
237 available, by using EXT_framebuffer_blit. Both mechanisms are also
238 throttled to avoid taking all resources when using them in a compositor
241 » Use (and cache) fragment shaders instead of texture combiners inside
242 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
243 to fixed functions depending on the level of support of the underlying
246 » Implement a new design for materials; this allows scaling up the
247 number of materials in a scene, and also makes copying materials
250 » Make Cogl materials responsible for depth testing, and add new
253 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
254 object instead of using the stencil buffer, or the scanline rasterizer
255 on platforms without a stencil buffer.
257 » Add ClutterDeformEffect, a base class for effects that deform an
258 actor's geometry when painting it; ClutterPageTurnEffect is an
259 implementation of a "page curl" deformation using the DeformEffect
262 » Always use scissoring when clipping, to reduce the amount of buffer
263 that has to be cleared.
265 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
266 a constructor property; the default remains fragment shader.
268 » Remove the button of the press event from the DragAction::drag-begin
269 and DragAction::drag-end signals. This is an API break from 1.3.4.
271 » Do not promote clipped redraws to full redraws.
273 » Improve the consistency of the default state name in ClutterState,
274 both in the API and in the serialization format.
276 » Fix a rounding error with the Text layout size.
278 » Add utility functions for CoglMatrix and CoglColor.
280 » Avoid a re-allocation cycle warning when resizing the surface of
281 a CairoTexture actor from within the allocate() implementation.
283 » Do not add the GL libraries for the EGL X11 backend.
285 » Add more checks for size of data passed to the shader types GValue
288 » Add width and height to the BindConstraint.
290 » Parse actions, constraints and effects inside an actor definition
293 » Merge the code of native and x11 backends for EGL into a single
294 backend; also allow creating GL context with the EGL backend.
296 » Use XSETTINGS to set up the backend configuration options, like
297 the font name, resolution, font options and double click options,
298 on X11; this also allows ClutterText actors created using the
299 default font name to be updated when the font name and options
300 change; similarly, this allows ClutterUnits to be updated when
301 the screen resolution changes.
303 » Implement the texture_from_pixmap extension support inside Cogl
304 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
306 » Documentation improvements in the API reference and in the cookbook.
308 » Use the -Bsymbolic-functions linker option on supported platforms
309 to avoid intra-library PLT jumps.

314 » Fix emission of scroll events on Windows.
333 Clutter 1.3.4 (07/06/2010)
334 ===============================================================================
336 • List of changes since Clutter 1.3.2
338 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
339 way an actor paints itself.
341 » Clutter provides a base class for effects painting to an
342 offscreen buffer, and a base class for effects using the
343 GL programmable pipeline (through the GLSL shader language).
345 » Clutter also provides some simple, shader-based effects:
346 ClutterBlurEffect, ClutterColorizeEffect and
347 ClutterDesaturateEffect.
349 » Effects can be applied to any actor, and can also be stacked.
351 » Add ClutterClickAction, an action that provides "button-like"
352 semantics for any ClutterActor.
354 » ClutterDragAction now moves the actor to which it has been applied
355 by default, using a class handler for the ::drag-motion signal.
357 » Add the :pick-with-alpha property to ClutterTexture; this property
358 allows using the alpha channel of a texture when picking it.
360 » Regenerate the mipmaps on COGL textures when a texture is modified.
362 » Documentation and build fixes.
371 Clutter 1.3.2 (24/05/2010)
372 ===============================================================================
374 • List of changes since Clutter 1.2
376 » Add ActorMeta, a class for run-time composition of actions and
377 constraints on a ClutterActor:
379 » Add ClutterAction, a class for implementing business logic
380 related to event handling.
382 » Add ClutterConstraint, a class for implementing business
383 logic related to sizing and positioning.
385 » ClutterDragAction is an Action sub-class that implements
386 signals and properties for dragging actors.
388 » ClutterAlignConstraint and ClutterBindConstraint are two
389 Constraint sub-classes that allow relative positioning
390 with fixed layout managers.
392 » Add ClutterState, an object for defining state transitions.
394 » Add ClutterBoxLayout:homogeneous property.
396 » Implement retained clip stacks.
398 » Support retained paths.
400 » Add an experimental vector3 API.
402 » Require GLib >= 2.18.
404 » Require Atk >= 1.7.
406 » Make ClutterActor implement AtkImplementor, and allow retrieving
407 an AtkObject from a ClutterActor.
409 » Improve ClutterText's Pango layout caching mechanism.
411 » Fix set up of the GLX_SGI_swap_control extension.
415 » Documentation fixes for Clutter and COGL.
417 » Fix the conformance test suite by executing every test unit in
420 » Add platform-dependent defines for Cogl.
422 » Update the MingW cross-compilation script.
424 » New recipe in the Cookbook.

448 » Compilation fixes for the EGL native backend
450 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
451 registration to avoid a run-time warning
453 » Handle TEXTURE_RECTANGLE_ARB in the 2D sliced textures, and add
454 a test case for that extension to avoid regressions
456 » Improve the strictness of the JSON parser in the internal copy
457 of JSON-GLib to which we fall back in the absence of the system
460 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
470 Clutter 1.2.0 (02/03/2010)
471 ===============================================================================
473 • List of changes since Clutter 1.1.14
475 » Improve the Animator API for consistency, and the implementation
476 to match the intended behaviour, as documented
478 » Add initial (and internal) support for queueing clipped region updates
479 and let the GLX texture-from-pixmap actor take advantage of it
481 » Support any pixel format in cogl_read_pixels()
483 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
486 » Consistently use :min-width and :min-height inside the Stage to define
487 the minimum size of the Stage window
489 » Implement the Scriptable interface for ClutterModel sub-classes; this
490 allows setting ClutterModel columns (both types and names) in
491 ClutterScript definitions
493 » Add support for unsigned integer indices in the VertexBuffer API
495 » Documentation fixes for Clutter: the coverage is now 100%
497 » Fixes for the EGL native backend
499 » Require libtool >= 2.2.6
501 » Improve tests coverage

528 from a foreign GL texture
530 » Split Clutter's debug annotations from the pick and paint mode
531 behavioural modifiers
533 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
534 actor using a ClutterFixedLayout manager will automatically benefit
537 » Fix the packing order of ClutterBox so that the convention of
538 first-in-first-painted is maintained
540 » Documentation fixes
548 Clutter 1.1.12 (16/02/2010)
549 ===============================================================================
551 • List of changes since Clutter 1.1.10
553 » Fix compilation on 64bit platforms
555 » Fix some races of the Stage resizing on X11
557 » Documentation fixes for Cogl: the coverage is now 100%
559 » Fix rounding errors in the preferred height of the ClutterText
562 » Remove redundant type checks in clutter_actor_get_paint_opacity()
564 » Add support for the GLX_INTEL_swap_event extension; when using this
565 extension on GLX the glXSwapBuffers() call becomes non-blocking and
566 Clutter will use an event to control the master clock.
568 » Improve consistency between ClutterBox and ClutterGroup.
570 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
571 Stage X window if the window was not created by Clutter itself
573 » Improve caching of GL constant values
575 » Optimize creating sub-textures of sub-textures
577 » Various fixes for the atlas and the journal
579 » Disable the atlas if FBOs are not supported
589 Clutter 1.1.10 (09/02/2010)
590 ===============================================================================
592 • List of changes since Clutter 1.1.8
594 » Fixed a regression in textures that caused all the textures to be
595 drawn as white rectangles.
597 » Fixed compilation with the Sun C compiler.
599 » Use SSE2 instructions to premultiply RGBA images, if available.
601 » Improve readability of ClutterActor::raise/::lower warnings.
608 Clutter 1.1.8 (08/02/2010)
609 ===============================================================================
611 • List of changes since Clutter 1.1.6
613 » Added ClutterAnimator, a class that allows defining complex
614 implicit animations involving multiple actors and states; this
615 class is mostly meant to be used through the ClutterScript
616 definition format, but it provides a convenience C API for
617 easily building animations.
619 » New experimental COGL API to expose "hardware" buffers such as PBOs or
620 drm surfaces. This API can be used, for instance, to make texture
623 » Fixed the issues with resizable stages getting a 1x1 window with
626 » Expose input devices for every event; by default, X11 and Windows
627 backends expose the core devices only.
629 » Add the ClutterStage:key-focus property, for key focus tracking.
631 » Allow setting transformable value types in ClutterAnimation when
632 calling clutter_animation_bind() and clutter_animation_update().
634 » Delay the creation of the default Stage until clutter_stage_get_default()
635 is actually called; this reduces the work of clutter_init().
637 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
639 » Improve the extendability of CoglTexture with internal backends.
641 » Add implicit texture atlasing; Cogl will try to put every texture
642 inside the same texture atlas by default, to avoid state changes
643 in the driver and (hopefully) improve performance.
645 » Fix notification of the cursor and selection changes in ClutterText;
646 this improves the usage of Clutter from A11Y toolkits.
648 » Do not wait for a frame if the system clock goes backwards.
650 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
652 » Documentation and build fixes.
665 Clutter 1.1.6 (18/01/2010)
666 ===============================================================================
668 • List of changes since Clutter 1.1.4
670 » Some fixes for the Win32 backend (bug #1905).
672 » Profiling support via the UProf library. Configure with
673 --enable-profile to get a report after each Clutter application is
676 » Improved conformance tests with coverage reports via gcov.
678 » ClutterTexture no longer tries to read back texture data into
679 g_malloc'd memory on unrealize (bug #1842).
681 » The CGL_• defines from cogl-defines.h have been removed. These
682 should not have been used by any applications, but if they were
683 being used then please replace them either with the Cogl enums or
684 with the appropriate GL_• enum if you are using GL directly.
686 » Added a delete-event signal to the stage.
688 » Fix for using cogl_rectangle with different texture coordinates
689 for multiple layers (bug #1937).
691 » Fix for using stencil and depth buffers in FBOs on Intel drivers
694 » Support for subtitles in ClutterMedia.
696 » ClutterGLX will now use an RGB visual by default. For
697 applications (and toolkit integration libraries) that want to
698 enable the ClutterStage:use-alpha property there is a new
699 function: clutter_x11_set_use_argb_visual().
701 » Fix ClutterText to allow using Pango markup and attributes in
702 the same actor (bug #1940).
714 Clutter 1.1.4 (03/01/2010)
715 ===============================================================================
717 • List of changes since Clutter 1.1.2
719 » Update the ClutterScript parser to be more resilient, and support
720 constructor and ChildMeta properties. The parser also respects the
721 order of the properties in the UI definitions when applying them,
722 and will apply the properties of an Actor after building the scene
725 » Simplified the implementation of LayoutManager sub-classes, and added
726 support for animating a layout manager.
728 » Allow short-circuiting some layout operations by setting a specific
729 flag on ClutterActor.
731 » Improve caching of the preferred size of a ClutterActor.
733 » Allow declaring "internal children" for a ClutterContainer
734 implementation: the memory management of these actors will be deferred
735 entirely to the Container.
737 » Let the ClutterStage honour the :opacity property and the alpha component
738 of the stage color. This requires support in the Clutter backend used.
740 » Improve Windows and OSX backends.
742 » Simplify the feature detection code for OpenGL; this also reduced the
743 required OpenGL version to 1.2.
745 » Improve the matrix stack handling code. The matrices can be debugged by
746 using the COGL_DEBUG environment variable, assuming that Clutter was
747 compiled with the right configure-time switch.
749 » Improve COGL API for draw buffers, and for offscreen buffer support.
751 » Add support for text direction to ClutterActor.
753 » Documentation, introspection and build fixes.
770 Clutter 1.1.2 (23/10/2009)
771 ===============================================================================
773 • List of changes since Clutter 1.0
775 » Add ClutterLayoutManager, an abstract proxy class for easily
776 writing layout management policies; also add ClutterLayoutMeta,
777 a class for storing layout properties.
779 » Add ClutterBox, a generic container actor that relies on a
780 ClutterLayoutManager instance to manage the layout of its
783 » Add the following layout managers:
785 - ClutterFixedLayout - a layout manager implementing the
786 policy used by ClutterGroup
788 - ClutterBinLayout - a layout manager for packing actors
789 as layers inside the same area, with per-actor alignment
791 - ClutterFlowLayout - a layout manager arranging actors as
794 - ClutterBoxLayout - a layout manager arranging actors as
797 » Remove the requirement for the backend-specific implementation
798 of ClutterStage to be a ClutterActor: a Stage implementation must
799 only implement the ClutterStageWindow interface. This cleans up
802 » COGL source tree clean up and rationalization; COGL now
803 knows the platform, and not only the driver (GL or GLES) so
804 we can migrate part of the low-level backend code from Clutter
805 to COGL where it makes sense.
807 » Remove code duplication across whole COGL.
809 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
810 have been fixed and confirmed working.
812 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
813 dumps the contents of each pick() buffer into a PNG file, for
816 » Allow interpolating intervals of ClutterUnits for animating
817 unit-based properties.
819 » Increase strictness and correctness of the ClutterUnits
822 » Add GValue transformation functions for ClutterPath to and
825 » Fix word movement in ClutterText; implement GObject getter for
826 :use-markup; emit notification for :position; decouple the
827 :text property from the :use-markup property.
829 » Do not queue redraws or relayouts on actors currently being
832 » Support #rrggbb and #rgb notations for ClutterColor.
834 » Multiple bug fixes.
836 » Provide _NET_WM_PID on the X11 stage implementation.
838 » Documentation and Introspection annotation fixes.
840 » Add test units for the ClutterActor size requesition.
844 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
845 back to Shave on older Automake versions.
865 Clutter 1.0.0 (28/07/2009)
866 ===============================================================================
868 • List of changes since 0.9.8
870 » Allow per-stage disabling of motion event throttling; this should allow
871 platforms or applications that require all the motion events not for
872 drawing purposes to get them exactly like Clutter gets them from the
875 » Various documentation fixes.
877 » Add per-word key navigation inside ClutterText.
879 » Fix the RGB<->HLS conversion.
881 » Various fixes for the OSX backend.
883 » Various build-related fixes.
891 Clutter 0.9.8 (17/07/2009)
892 ===============================================================================
894 • List of changes since 0.9.6
896 » Add more introspection annotations for language bindings.
898 » Fix a bug in clutter_animation_set_alpha(), which also broke the
899 clutter_actor_animate_with_alpha() function.
901 » Check if the stage requires a relayout before showing it; this fixes
902 a bug in the X11-based backends, especially under compositing window
903 managers, where a 640x480 window would flicker before the default
904 stage was shown for the first time.
906 » Performance fixes for Cogl.
908 » Sliced textures were broken by the COGL journalling.
910 » Use the redraw cycle when asynchronously loading textures from
913 » Miscellaneous compilation fixes for the OS X and Windows backends.
915 » Allow querying from within the paint function of an Actor whether
916 the actor is currently being directly painted or by a Clone actor.
918 » In the GLX backend, when using the non-implicit sync-to-vblank inside
919 glXSwapBuffers(), call glFinish() to avoid potential tearing.
929 Clutter 0.9.6 (01/07/2009)
930 ===============================================================================
932 • List of changes since 0.9.4:
934 » Allow the manipulation of the actor's transformation matrix, so that is
935 is possible to apply additional transformations in a way that is
936 compatible with the transformations already applied by the scene graph.
938 » Fix a race in the X11 backend that happened between resizing the stage
939 drawable and the call to glViewport().
941 » Merge the cogl-journal-batching branch; this branch implements batching
942 the geometry of the elements of the scene graph before sending it to
943 OpenGL, thus minimizing the number of state changes and improving the
944 overall performance of Clutter-based applications.
946 » Add more debugging states for Clutter and COGL, which allow the developer
947 to track the state of the journal; to check the VBO fallback paths; to
948 disable picking for reliable profiling; to disable software-side matrix
949 transformations in favour of the driver/GPU ones.
951 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
952 semantics; applications that drop into raw GL are, though, ignoring all
953 the caching performed by COGL and might incur in performance issues.
955 » Fixed the :load-async and :load-data-async properties of Texture by
956 removing the unneeded G_PARAM_CONSTRUCT flag.
958 » Added an initial migration guide that shows the porting process from
959 older releases of Clutter to the 1.0 API; the first chapter deals with
960 the migration from ClutterEffect to the new implicit animations API.
962 » Fixed MT-safety for the master clock.
966 Ole André Vadla Ravnås
969 Clutter 0.9.4 (19/06/2009)
970 ===============================================================================
972 • List of changes since 0.9.2:
974 » Set the layout height in ClutterText, so that wrapping and ellipsization
975 work correctly to fill all the allocated area.
977 » Remove all the units-based API, and migrate all the positional and
978 dimensional accessors to use floating point values when dealing with
979 pixels. All the properties dealing with pixels now that a floating
982 » Add the ability to track wether an actor is going to be painted or not,
983 using the "mapped" flag. This also allows Clutter to be more strict
984 in the handling of the scenegraph, ensuring correctness and avoiding
985 wasting resources on nodes that won't be painted.
987 » Add debugging facilities for COGL, similar to those of Clutter; through
988 them is also possible to have an on screen debugging mode that shows the
989 boundaries of each rectangle sent to the GPU.
991 » Rework "units" into real logical distance units that can be converted
992 between millimeters, typographic points and ems into pixels.
994 » Simplify the Animation class to avoid redundancy and the possibility
995 of it going out of sync with the Timeline and Alpha instances it uses.
997 » Move every operation into a single "master clock" source that advances
998 the timelines, dispatches events and redraws the stages in a predictable
999 sequence, thus avoiding unneeded redraws. The default is to follow the
1000 sync-to-vblank cycle, if it is supported by the drivers.
1002 » Cache the glyphs geometry into a vertex buffer object to avoid
1003 resubmitting too much information to the GPU.
1005 » Rework the behaviour of ClutterModel when a filter is applied.
1007 » Allow submitting premultiplied texture data; this removes the need
1008 for unpremultiplying data in CairoTexture.
1010 » Add a simple API for submitting blending and texture combining modes
1011 through a string description.
1013 » Move Timelines to pure time-based objects.
1015 » Lots of performance improvements.
1017 » Removal of all the deprecated API.
1019 » Removal of all the fixed point entry points.
1021 » Lots of documentation fixes - the coverage is now 99% of the exported
1022 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
1024 » Generate the GObject Introspection data for both Clutter and COGL
1027 » Build environment fixes.

1306 Clutter 0.9.0 (30/01/2009)
1307 ===============================================================================
1309 • List of changes between 0.8.6 and 0.9.0
1311 » ClutterText is a new actor allowing text display, text editing
1312 both in multi-line and single-line modes, and text selection using
1313 the pointer devices and the keyboard. ClutterText supercedes both
1314 ClutterLabel and ClutterEntry.
1315 » ClutterClone is a new actor that allows cloning of other actors,
1316 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
1317 » ClutterBindingPool is a new API that allows to easily add key bindings
1319 » ClutterAnimation is a new API for implicit animations, similar to
1320 the tweening API used in toolkits like jQuery, Tween and Flash. This
1321 new API supercedes the ClutterEffect API.
1322 » ClutterAlpha uses "animation modes" instead of raw function
1323 pointers; it is still possible to pass alpha functions. The alpha
1324 functions provided by Clutter have been removed from the public
1325 API. It is possible to register global alpha functions and use
1326 them though a logical id.
1327 » The interval of the ClutterAlpha:alpha property has been changed
1328 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
1329 the addition of "overshooting" easing modes.
1330 » COGL now supports backface culling.
1331 » The COGL-based Pango renderer is public API and it is accessible
1332 to developers. It is also possible to access the PangoContext used
1333 by Clutter in order to create PangoLayouts to render text.
1334 » The ClutterFixed API has been moved to COGL.
1335 » COGL does not depend on Clutter data types anymore.
1336 » The ClutterMedia interface has been overhauled: implementations
1337 now must only override the interface properties. The ranges of
1338 some properties have been changed to normalized values.
1339 » COGL now exposes only floating point entry points, and reserves
1340 the eventual conversion to fixed point only when needed. The
1341 fixed point type and macros are publicly available for developers
1342 concerned about floating point operations.
1343 » COGL has a new Vertex Attribues API that allows submitting an
1344 extensible number of vertex attributes to OpenGL in a way that
1345 does not require format conversions and allows fast re-use.
1346 » COGL has a new Material API that decouples paths from fills; it
1347 is possible to create an arbitrary path and fill it with a COGL
1348 texture. The Material API also allows setting multiple texture
1349 layers and defining the blend modes and colors.
1350 » ClutterTexture has the ability to use a worker thread to asynchronously
1351 load an image from a file, as long as the GLib threading support has
1352 been enabled prior to calling clutter_init().
1353 » Clutter now supports localization of the help output, and it
1354 also supports globally setting the text direction for non left to
1356 » ClutterCairoTexture is a new actor that allows using Cairo
1357 to draw on a ClutterTexture; since Cairo does not have an OpenGL
1358 backend, the drawing is not hardware accelerated.
1359 » Clutter has a unit testing suite, based on the GLib unit test
1360 framework, which can be used to track regressions.
1361 » A ClutterPath object has been added, and it is used by the
1362 BehaviourPath. The Path object allows defining paths using a set
1363 of coordinates and operations. A Path can be "painted" either using
1364 COGL primitives or using Cairo primitives, allowing an easier way
1365 to paint non-rectangular shaped actors.
1366 » ClutterInterval is a simple object, used by ClutterAnimation, that
1367 describes an interval between two values, and interpolates between
1368 the initial and final values of the interval.

1511 Clutter 0.8.0 (10/07/2008)
1512 ===============================================================================
1514 • List of changes between 0.7.6 and 0.8.0

1581 » Warn if no usable pointer device are available on X11 backends.
1583 » Improve the request for the best pixel format on win32.
1585 » Fix a regression when sizing the ClutterStage on backends that

1603 Clutter 0.7.2 (23/06/2008), "Kedoke"
1604 ===============================================================================
1606 • List of changes between 0.7.0 and 0.7.2
1608 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
1609 to TRUE the texture will return a preferred width maintaining the
1610 aspect ratio with the given height and a preferred height maintaining
1611 the aspect ratio with the given width. This allows to set the width or
1612 the height and have the texture automatically request the height or the
1613 width respectively while maintaining the aspect ratio of the original
1616 » Added XINPUT support on the X11 backends; this provides an initial
1617 support for multiple input devices. The API is X11-specific, and
1618 provides support for querying at run-time support for XINPUT, for
1619 getting a list of input devices and for getting the type of each
1622 » The 'fruity' backend also features multiple device support.

1640 Clutter 0.7.0 (13/06/2008), "Booska"
1641 ===============================================================================
1643 • List of changes between 0.6 and 0.7.0
1645 » COGL, the underlying GL abstraction layer in Clutter, has been
1646 completely rewritten from the ground up. Its no longer a conceptual
1647 hack but a documented, fully featured library pretty much in its
1648 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
1649 OpenGL ES 2.0, providing a smart uniform API over these libraries
1650 with various utility features such as texture tiling abstractions,
1651 paths and primitive rendering, FBO, shaders, etc.
1653 » Clutter now provides an experimental backend for the Apple(tm)
1654 iPhone and iPod Touch families of products.
1656 » The Windows platform is now natively supported instead of
1657 relying on the SDL libraries. The win32 backend is still
1660 » The X11 based backends now feature support for Actors that wrap
1661 external X drawables (i.e the texture-from-pixmap extension and
1664 » Clutter now seamlessly supports multiple stages on the backends
1665 that allow this feature.
1667 » The custom Pango renderer has been completely rewritten, now using
1668 the more modern and maintained PangoCairo (instead of FT2), and avoids
1669 nasty subclassing hacks, supports smooth fast scaling of text, has
1670 many edge case issues fixed and it still is very efficient (using
1671 a texture glyph cache). It is even a little bit faster.
1673 » Better texture support, timeline improvements, ClutterLabel and
1674 ClutterEntry improvements, and container child properties are among
1675 the new features - too many to fit in the NEWS file.
1679 » #358 - "window resizing doesn't show scaled stage"

1751 Clutter 0.6.0 (18/02/2008)
1752 ==========================
1754 • List of changes between 0.5.6 and 0.6.0
1756 » New documentation sections inside the API reference, describing
1757 the animation framework.
1759 » New API in ClutterActor for computing the actor's vertices in

1770 Clutter 0.5.6 (11/02/2008)
1771 ==========================
1773 • List of changes between 0.5.4 and 0.5.6
1775 » Reverted a last minute change in the depth sorting function of
1778 » Added the clutter_actor_move_anchor_point() family of functions,
1779 which will set the anchor point at the given coordinates while
1780 adjusting the actor postion so that the relative position of the
1781 actor toward its parent remains the same.
1783 » Provide a fallback for finding the Clutter alpha functions inside
1784 a UI definition for ClutterScript in case g_module_open() fails.
1786 » Add initial Frame Buffer Objects support in ClutterTexture; using
1787 FBOs, where supported by the hardware and drivers, it's possible to
1788 create a ClutterTexture from any actor.
1790 • List of bugs fixed

1820 Clutter 0.5.4 (25/01/2008)
1821 ==========================
1823 • List of changes between 0.5.2 and 0.5.4
1825 » A clutter-x11-<major>.<minor> pkg-config file is installed along
1826 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
1827 ones, for libraries and applications depending on the X11-based
1828 backends (GLX and EGLX).
1830 » Textures are correctly unrealized before changing and freeing the
1833 » It is now possible to block the automatic call to clutter_main_quit()
1834 when closing the stage window using the frame controls by connecting
1835 an handler for the ::event signal on the Clutter stage and checking
1836 for the CLUTTER_DELETE event type and returning TRUE. This allows
1837 the usage of other main loops with GLib reactors (like Python's twisted)
1838 with Clutter without triggering assertions by closing the stage window.
1840 • List of bugs fixed
1842 » #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]

1857 API change [Josh Stewart]
1859 Clutter 0.5.2 (14/01/2008)
1860 ==========================
1862 • List of changes between 0.5.0 and 0.5.2
1864 » ClutterModelDefault has been renamed to ClutterListModel
1866 » ClutterModel now has vector-based variants for append, prepend and
1867 insert methods; these methods are useful for bindings
1869 » Add units-based variant for clutter_actor_move_by()
1871 • List of bugs fixed
1873 » #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
1874 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
1876 Clutter 0.5.0 (02/01/2008)
1877 ==========================
1879 • List of changes between 0.4.2 and 0.5.0
1881 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
1882 flag set will receive events from the underlying backend; the event
1883 propagation chain will be walked in two directions (from the actor to
1884 the top-level container and back) with the ability to block it in
1887 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
1889 » ClutterScore, an object for controlling timelines; using a score
1890 instance is possible to start multiple timelines at once, or start
1891 a timeline after another has emitted the ::complete signal.
1893 » ClutterScript, an object for parsing a scene from an external file or
1894 a buffer; the scene is described using JSON (JavaScript Object Notation):
1895 every object is defined using its class and properties, and container
1896 objects can have their children defined as well. It is also possible
1897 do describe top-level objects such as timelines and behaviours, and to
1898 automatically connect signal handlers to signal names.
1900 » ClutterTimelines duration can now be set in milliseconds using the
1901 :duration property; the default framerate will be used to compute the
1902 actual duration in frames. The default framerate will be set by the
1903 backend, and can be overridden by the application.
1905 » ClutterTimelines direction can now be set using the :direction
1906 property; a timeline can be set to proceed forward or backward,
1907 and the direction can also be change while the timeline is still
1910 » New, experimental OSX backend.
1912 » Build environment for MS VisualStudio 2005.
1914 » ClutterModel, a generic list-based model object that can be used to
1915 implement actors following the Model-Viewer-Controller design pattern.
1916 Clutter provides a default implementation of ClutterModel, called
1917 ClutterModelDefault and using the GSequence data structure from GLib
1918 to optimize insertion and look up.
1920 » Add the ability to grab pointer and keyboard events: if an actor
1921 is set to have a grab it'll be the only one receiving events until
1922 it releases the grab.
1924 » Add the ability for an actor to receive the key focus; an actor
1925 with key focus will always receive the key events, even if it did
1926 not acquire the keyboard grab.
1928 » It is now possible to set the GL "fog" (also known as "depth cueing")
1929 effect on the ClutterStage; if the fog is enabled, actors farther
1930 away from the view point will fade into the stage background color.
1932 » Each actor now has an "anchor point", a point defined in the actor's
1933 coordinate space that will be used as the origin when scaling and
1934 rotation transformations.
1936 » Every pixel-based API has been doubled with a corresponding
1937 ClutterUnits-based function (postfixed with a '-u'), for instance:
1939 clutter_actor_set_position() - clutter_actor_set_positionu()
1940 clutter_actor_set_size() - clutter_actor_set_sizeu()
1941 clutter_actor_set_depth() - clutter_actor_set_depthu()
1943 This allows sub-pixel precision and device independence.
1945 » The ClutterLabel actor now tries very hard to provide a sane
1946 default size, if no bounding box has been requested; this fixes
1947 the :alignment property and allows the addition of the :justify
1950 » The SDL backend can now be compiled under win32 with MingW; this
1951 backend is still marked as experimental.
1953 » The OSX backend allows the compilation of Clutter under OS X; this
1954 backend is experimental.

2102 Clutter 0.3 (29/06/2007)
2103 ========================
2105 • List of changes between 0.2.3 and 0.3
2106 » Clutter now supports both switchable windowing system and GL backends.
2107 Window systems supported include GLX, EGL and SDL.
2109 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2110 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2111 yet documented - usage external to Clutter is not yet advised.
2113 Backends may provide specific command line options.
2119 The GLX backend is built by default and is currently the most
2120 developed, supported and featured windowing system backend. Only
2121 OpenGL is supported via GLX.
2125 Clutter has experimental support for using SDL. Open GL is supported as
2126 is OpenGL ES via Dogles (very experimental).
2130 Clutter has experimental support for using EGL. Only Open GL ES
2131 is supported by EGL.
2133 EGL support assumes an EGL implementation running atop X Windows.
2138 Clutter now has experimental support for Open GL ES.
2139 Current known issues;
2141 + Unrealising a ClutterTexture will not move pixel data from video
2142 into system memory but simply destroy it.
2143 + BGRA, YUV Texture data not currently supported.
2145 (Use the clutter_feature API to probe for above at runtime)
2147 Open Source ES implementations this has been tested against
2148 include `Vincent' and `dgles'. Support for commerical
2149 implementations may require modifications to the configure.ac
2152 vincent: http://ogl-es.sourceforge.net/
2153 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2155 dgles: http://developer.hybrid.fi/dgles/index.html
2157 » New ClutterEffect class provides a simplified (and thus less flexible)
2158 API wrapping around behaviours, alphas and timelines.
2159 » New Behaviours - bspline, ellipsis, rotation.
2160 » New built in Alpha functions;
2161 CLUTTER_ALPHA_SINE_INC
2162 CLUTTER_ALPHA_SINE_DEC
2163 CLUTTER_ALPHA_SINE_HALF
2164 CLUTTER_ALPHA_SQUARE
2165 CLUTTER_ALPHA_SMOOTHSTEP_INC
2166 CLUTTER_ALPHA_SMOOTHSTEP_DEC
2167 CLUTTER_ALPHA_EXP_INC
2168 CLUTTER_ALPHA_EXP_DEC
2169 » New Actors and interfaces
2170 + ClutterLayout, for writing extended layout support in actors
2171 + ClutterContainer, for generic container actors
2172 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
2173 + ClutterEntry, text entry actor
2174 » ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
2175 » All internal math now fixed point based.
2176 » Clutter now has it own internal event queue.
2177 » ClutterStage new features;
2178 + Title property for naming in window decorations.
2179 + Perspective setting - The stages perspective can now be modified.
2180 » New Clutter_actor •project API calls allow for querying of tranformed
2181 actor vertices and points.
2182 » New Clutter Feature checks.
2183 » Initial ClutterUnit implementation for device independant positioning.
2184 • List of Bugs fixed
2185 » Various issues with very poor performance and Intel drivers.
2186 » #138 Fix typo in x rotation transform.
2188 Clutter 0.2.3 (2007-04-11)

2217 Clutter 0.2 (18-01-2007)
2218 ========================
2220 • List of changes between 0.2 and 0.1
2221 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
2222 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
2223 » Actors now have an initial floating reference; this means you
2224 don't have to explicitely unref them: every memory an actor
2225 allocates will be freed when the group containing the actor will
2227 » Add basic run-time detection of GL features.
2228 + Use GL_TEXTURE_RECTANGLE_ARB if available.
2229 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2230 » Add API for behaviours. A ClutterBehaviour is an object which
2231 drives a set of actors using one or more properties depending
2232 on the value of an "alpha" function.
2233 + Provide simple behaviours: ClutterBehaviourOpacity,
2234 ClutterBehaviourPath and ClutterBehaviourScale.
2235 + Provide simple alpha functions for ramps and sine waveforms.
2236 » Add fixed point API for embedded platforms with no FPU.
2237 » Add support for command line switches to Clutter, like debug
2238 flags and abort on warnings; also allow application to hook up
2239 into the initialisation sequence to add their own command line
2241 » Add Pango GL renderer for Clutter, and use it to render text
2242 inside the ClutterLabel actor; this decrease texture memory
2244 » Redo Clutter Label widget, using the new Pango renderer.
2245 » Clutter Textures do not store local pixbuf copy (of texture).
2246 » Redo group and actor scale/sizing API and functionality.
2247 » Add memory management API for ClutterColor, and string parsing.
2249 » #199 - Little group handling fix?
