129 Clutter 1.5.6 2010-11-19
130 ===============================================================================
132 • List of changes since Clutter 1.5.4
134 » Deprecate ClutterBehaviour and its sub-classes: the same functionality
135 is available using the animation framework.
137 » Add ClutterSnapConstraint, a constraint implementation that snaps
138 together the edges of two actors.
140 » Add ClutterPathConstraint::node-reached.
142 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
143 not used internally any more, and since it's not integrated with
144 the master clock it's of relative use.
146 » Add a named, global color palette.
148 » Add the ClutterTimeline:reverse property, for automatically
149 reversing the direction of a timeline after the emission of
150 the ::completed signal.
152 » Performance improvements in the clip stack.
154 » Do not use pointer grabs in ClutterClickAction.
156 » Improve the internally used Cogl API for primitives, paths and

159 » Allow using the COGL_DEBUG environment variable to disable the
162 » Plug a nasty infinite loop in the XSETTINGS implementation.
164 » Internally rename CoglMaterial to CoglPipeline; this should make

167 » Add support for clipped redraws on EGL using the NOK_swap_region
172 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
174 » Update examples in the Cookbook.

234 Clutter 1.5.2 (04/10/2010)
235 ===============================================================================
237 • List of changes since Clutter 1.4.0
239 » Add API to ClutterActor to allow any actor to define its 3D paint
240 volume and its stage-relative 2D bounding box; the paint volume is
241 the 3D space occupied by an actor during the paint sequence. This
242 allows better sizing of the FBOs, and opens the door to scenegraph
243 culling and accurate clipped redraws. The mechanism is opt-in: actors
244 have to implement the get_paint_volume() virtual function. Callbacks
245 attached to the ::paint signal will also disable any culling and
246 clipped redraw in place internally.
248 » Plug a leak in ClutterActor by disposing all constraints.
250 » Rework the build system to be as non-recursive as possible; this should
251 speed up the build of Clutter, and makes the build layout easier to
252 understand and update.
254 » Remove the internal copy of JSON-GLib; the internal copy was falling
255 behind at a spectacular level, and it was actually making the build
256 rather complicated - also by adding an unwanted, but needed,
257 introspection data generation. The required JSON-GLib has also been
258 bumped to the new stable release, 0.12.0.
260 » Use g_object_install_properties() with GLib 2.26.
262 » Implement ClutterContainer::child-notify, which slipped through the
263 cracks of many development cycles without anyone noticing.
265 » Document and test clutter_actor_contains(), especially the corner
268 » Plug a leak in CoglTexture2DSliced.
270 » Plug a leak in ClutterAnimator's handling of timelines.
272 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
273 errors when the GLX pixmap is destroyed behind Cogl's back.
286 Clutter 1.4.0 (24/09/2010)
287 ===============================================================================
289 • List of changes since Clutter 1.3.14
291 » Add support for describing ClutterState states using ClutterAnimators
296 » Include ClutterConstraints into the allocation phase, to avoid layout
297 cycles and improve the performance.
299 » Add new recipes to the Cookbook to illustrate constraints-based
302 » Fix the request mode of ClutterBoxLayout.
304 » Fix the handling of transformations in ClutterOffscreenEffect.
306 » Documentation and introspection fixes.

324 » Fix applying layout properties from ClutterScript definitions in case
325 of multiple children.
327 » Add a Clutter EGL backend for Intel CEx100 platforms.
329 » Add new recipes in the Cookbook:
330 - texture cross-fading
331 - ClutterScript definitions
334 - reusing complex animations
336 » Add methods to retrieve the clicked button and to force a release
339 » Documentation fixes in the API reference.
341 » Cache a full pick buffer and re-use it in case the scene does not change
344 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
346 » Allow detaching animations created with clutter_actor_animate().
348 » Depend on GObject-Introspection >= 0.9.5.
350 » Provide introspection data for the X11-specific API, like
351 ClutterX11TexturePixmap
353 » Use a template material for ClutterTexture to minimize the creation of
356 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
357 :x-drag-threshold and :y-drag-threshold.
359 » Allow disabling the -Bsymbolic flag when linking.
361 » Use gettext >= 0.17 to handle the localization.
363 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
364 a crash when dealing with clip stacks.
366 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
367 freeing the X11 Pixmap to avoid an error.
369 » Avoid regenerating the CoglMaterial programs too many times.
390 Clutter 1.3.12 (16/08/2010)

412 emission of the ::notify signal on property changes.
414 » Re-use the Cogl texture atlas for the CoglPango glyphs cache,
415 and improve the performance with large font sizes.
417 » Various fixes in the Materials comparison and inheritance.
419 » Add the ability to associate a user program to a material.

492 » Add missing public functions from COGL headers.
494 » Fix GLES build after the Cogl material changes.
496 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
498 » Split the clutter_state_change() method into two:
499 clutter_state_set_state(), for animated state changes; and
500 clutter_state_warp_to_state() for immediate state changes.
502 » Documentation and introspection fixes.
516 Clutter 1.3.6 (30/06/2010)
517 ===============================================================================
519 • List of changes since Clutter 1.3.4
521 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
522 available, by using EXT_framebuffer_blit. Both mechanisms are also
523 throttled to avoid taking all resources when using them in a compositor
526 » Use (and cache) fragment shaders instead of texture combiners inside
527 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
528 to fixed functions depending on the level of support of the underlying
531 » Implement a new design for materials; this allows scaling up the
532 number of materials in a scene, and also makes copying materials
535 » Make Cogl materials responsible for depth testing, and add new
538 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
539 object instead of using the stencil buffer, or the scanline rasterizer
540 on platforms without a stencil buffer.
542 » Add ClutterDeformEffect, a base class for effects that deform an
543 actor's geometry when painting it; ClutterPageTurnEffect is an
544 implementation of a "page curl" deformation using the DeformEffect
547 » Always use scissoring when clipping, to reduce the amount of buffer
548 that has to be cleared.
550 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
551 a constructor property; the default remains fragment shader.
553 » Remove the button of the press event from the DragAction::drag-begin
554 and DragAction::drag-end signals. This is an API break from 1.3.4.
556 » Do not promote clipped redraws to full redraws.
558 » Improve the consistency of the default state name in ClutterState,
559 both in the API and in the serialization format.
561 » Fix a rounding error with the Text layout size.
563 » Add utility functions for CoglMatrix and CoglColor.
565 » Avoid a re-allocation cycle warning when resizing the surface of
566 a CairoTexture actor from within the allocate() implementation.
568 » Do not add the GL libraries for the EGL X11 backend.
570 » Add more checks for size of data passed to the shader types GValue
573 » Add width and height to the BindConstraint.
575 » Parse actions, constraints and effects inside an actor definition
578 » Merge the code of native and x11 backends for EGL into a single
579 backend; also allow creating GL context with the EGL backend.
581 » Use XSETTINGS to set up the backend configuration options, like
582 the font name, resolution, font options and double click options,
583 on X11; this also allows ClutterText actors created using the
584 default font name to be updated when the font name and options
585 change; similarly, this allows ClutterUnits to be updated when
586 the screen resolution changes.
588 » Implement the texture_from_pixmap extension support inside Cogl
589 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
591 » Documentation improvements in the API reference and in the cookbook.
593 » Use the -Bsymbolic-functions linker option on supported platforms
594 to avoid intra-library PLT jumps.
596 » Fix painting transparent stages on X11 using the :use-alpha property
599 » Fix emission of scroll events on Windows.
618 Clutter 1.3.4 (07/06/2010)
619 ===============================================================================
621 • List of changes since Clutter 1.3.2
623 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
624 way an actor paints itself.
626 » Clutter provides a base class for effects painting to an
627 offscreen buffer, and a base class for effects using the
628 GL programmable pipeline (through the GLSL shader language).
630 » Clutter also provides some simple, shader-based effects:
631 ClutterBlurEffect, ClutterColorizeEffect and
632 ClutterDesaturateEffect.
634 » Effects can be applied to any actor, and can also be stacked.
636 » Add ClutterClickAction, an action that provides "button-like"
637 semantics for any ClutterActor.
639 » ClutterDragAction now moves the actor to which it has been applied
640 by default, using a class handler for the ::drag-motion signal.
642 » Add the :pick-with-alpha property to ClutterTexture; this property
643 allows using the alpha channel of a texture when picking it.
645 » Regenerate the mipmaps on COGL textures when a texture is modified.
647 » Documentation and build fixes.
656 Clutter 1.3.2 (24/05/2010)
657 ===============================================================================

661 » Add ActorMeta, a class for run-time composition of actions and
662 constraints on a ClutterActor:
664 » Add ClutterAction, a class for implementing business logic
665 related to event handling.
667 » Add ClutterConstraint, a class for implementing business
668 logic related to sizing and positioning.
670 » ClutterDragAction is an Action sub-class that implements
671 signals and properties for dragging actors.
673 » ClutterAlignConstraint and ClutterBindConstraint are two
674 Constraint sub-classes that allow relative positioning
675 with fixed layout managers.
677 » Add ClutterState, an object for defining state transitions.
679 » Add ClutterBoxLayout:homogeneous property.
681 » Implement retained clip stacks.
683 » Support retained paths.
685 » Add an experimental vector3 API.
687 » Require GLib >= 2.18.
689 » Require Atk >= 1.7.
691 » Make ClutterActor implement AtkImplementor, and allow retrieving
692 an AtkObject from a ClutterActor.
694 » Improve ClutterText's Pango layout caching mechanism.
696 » Fix set up of the GLX_SGI_swap_control extension.
700 » Documentation fixes for Clutter and COGL.
702 » Fix the conformance test suite by executing every test unit in
705 » Add platform-dependent defines for Cogl.
707 » Update the MingW cross-compilation script.

735 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
736 registration to avoid a run-time warning
738 » Handle TEXTURE_RECTANGLE_ARB in the 2D sliced textures, and add
739 a test case for that extension to avoid regressions
741 » Improve the strictness of the JSON parser in the internal copy
742 of JSON-GLib to which we fall back in the absence of the system
745 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
755 Clutter 1.2.0 (02/03/2010)
756 ===============================================================================
758 • List of changes since Clutter 1.1.14
760 » Improve the Animator API for consistency, and the implementation
761 to match the intended behaviour, as documented
763 » Add initial (and internal) support for queueing clipped region updates
764 and let the GLX texture-from-pixmap actor take advantage of it
766 » Support any pixel format in cogl_read_pixels()
768 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
771 » Consistently use :min-width and :min-height inside the Stage to define
772 the minimum size of the Stage window
774 » Implement the Scriptable interface for ClutterModel sub-classes; this
775 allows setting ClutterModel columns (both types and names) in
776 ClutterScript definitions
778 » Add support for unsigned integer indices in the VertexBuffer API
780 » Documentation fixes for Clutter: the coverage is now 100%
782 » Fixes for the EGL native backend

805 border of the Stage window
807 » Take the InputDevice of an event into consideration when throttling
810 » Round the coordinates when clipping to a rectangle in window coordinates
812 » Always trust the user-provided coordinates when creating a CoglTexture
813 from a foreign GL texture
815 » Split Clutter's debug annotations from the pick and paint mode
816 behavioural modifiers
818 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
819 actor using a ClutterFixedLayout manager will automatically benefit
822 » Fix the packing order of ClutterBox so that the convention of
823 first-in-first-painted is maintained
825 » Documentation fixes
833 Clutter 1.1.12 (16/02/2010)

844 » Fix rounding errors in the preferred height of the ClutterText
847 » Remove redundant type checks in clutter_actor_get_paint_opacity()
849 » Add support for the GLX_INTEL_swap_event extension; when using this
850 extension on GLX the glXSwapBuffers() call becomes non-blocking and
851 Clutter will use an event to control the master clock.
853 » Improve consistency between ClutterBox and ClutterGroup.
855 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
856 Stage X window if the window was not created by Clutter itself
858 » Improve caching of GL constant values
860 » Optimize creating sub-textures of sub-textures
862 » Various fixes for the atlas and the journal

880 drawn as white rectangles.
882 » Fixed compilation with the Sun C compiler.
884 » Use SSE2 instructions to premultiply RGBA images, if available.
886 » Improve readability of ClutterActor::raise/::lower warnings.
893 Clutter 1.1.8 (08/02/2010)
894 ===============================================================================
896 • List of changes since Clutter 1.1.6
898 » Added ClutterAnimator, a class that allows defining complex
899 implicit animations involving multiple actors and states; this
900 class is mostly meant to be used through the ClutterScript
901 definition format, but it provides a convenience C API for
902 easily building animations.
904 » New experimental COGL API to expose "hardware" buffers such as PBOs or
905 drm surfaces. This API can be used, for instance, to make texture
908 » Fixed the issues with resizable stages getting a 1x1 window with
911 » Expose input devices for every event; by default, X11 and Windows
912 backends expose the core devices only.
914 » Add the ClutterStage:key-focus property, for key focus tracking.
916 » Allow setting transformable value types in ClutterAnimation when
917 calling clutter_animation_bind() and clutter_animation_update().
919 » Delay the creation of the default Stage until clutter_stage_get_default()
920 is actually called; this reduces the work of clutter_init().
922 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
924 » Improve the extendability of CoglTexture with internal backends.
926 » Add implicit texture atlasing; Cogl will try to put every texture
927 inside the same texture atlas by default, to avoid state changes
928 in the driver and (hopefully) improve performance.
930 » Fix notification of the cursor and selection changes in ClutterText;
931 this improves the usage of Clutter from A11Y toolkits.
933 » Do not wait for a frame if the system clock goes backwards.
935 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
937 » Documentation and build fixes.
950 Clutter 1.1.6 (18/01/2010)
951 ===============================================================================
953 • List of changes since Clutter 1.1.4
955 » Some fixes for the Win32 backend (bug #1905).
957 » Profiling support via the UProf library. Configure with
958 --enable-profile to get a report after each Clutter application is
961 » Improved conformance tests with coverage reports via gcov.
963 » ClutterTexture no longer tries to read back texture data into
964 g_malloc'd memory on unrealize (bug #1842).
966 » The CGL_• defines from cogl-defines.h have been removed. These
967 should not have been used by any applications, but if they were
968 being used then please replace them either with the Cogl enums or
969 with the appropriate GL_• enum if you are using GL directly.
971 » Added a delete-event signal to the stage.
973 » Fix for using cogl_rectangle with different texture coordinates
974 for multiple layers (bug #1937).
976 » Fix for using stencil and depth buffers in FBOs on Intel drivers
979 » Support for subtitles in ClutterMedia.
981 » ClutterGLX will now use an RGB visual by default. For
982 applications (and toolkit integration libraries) that want to
983 enable the ClutterStage:use-alpha property there is a new
984 function: clutter_x11_set_use_argb_visual().
986 » Fix ClutterText to allow using Pango markup and attributes in
987 the same actor (bug #1940).
999 Clutter 1.1.4 (03/01/2010)
1000 ===============================================================================
1002 • List of changes since Clutter 1.1.2
1004 » Update the ClutterScript parser to be more resilient, and support
1005 constructor and ChildMeta properties. The parser also respects the
1006 order of the properties in the UI definitions when applying them,
1007 and will apply the properties of an Actor after building the scene
1010 » Simplified the implementation of LayoutManager sub-classes, and added
1011 support for animating a layout manager.
1013 » Allow short-circuiting some layout operations by setting a specific
1014 flag on ClutterActor.
1016 » Improve caching of the preferred size of a ClutterActor.
1018 » Allow declaring "internal children" for a ClutterContainer
1019 implementation: the memory management of these actors will be deferred
1020 entirely to the Container.
1022 » Let the ClutterStage honour the :opacity property and the alpha component
1023 of the stage color. This requires support in the Clutter backend used.
1025 » Improve Windows and OSX backends.
1027 » Simplify the feature detection code for OpenGL; this also reduced the
1028 required OpenGL version to 1.2.
1030 » Improve the matrix stack handling code. The matrices can be debugged by
1031 using the COGL_DEBUG environment variable, assuming that Clutter was
1032 compiled with the right configure-time switch.
1034 » Improve COGL API for draw buffers, and for offscreen buffer support.
1036 » Add support for text direction to ClutterActor.
1038 » Documentation, introspection and build fixes.
1055 Clutter 1.1.2 (23/10/2009)
1056 ===============================================================================
1058 • List of changes since Clutter 1.0
1060 » Add ClutterLayoutManager, an abstract proxy class for easily
1061 writing layout management policies; also add ClutterLayoutMeta,
1062 a class for storing layout properties.
1064 » Add ClutterBox, a generic container actor that relies on a
1065 ClutterLayoutManager instance to manage the layout of its
1068 » Add the following layout managers:
1070 - ClutterFixedLayout - a layout manager implementing the
1071 policy used by ClutterGroup
1073 - ClutterBinLayout - a layout manager for packing actors
1074 as layers inside the same area, with per-actor alignment
1076 - ClutterFlowLayout - a layout manager arranging actors as
1079 - ClutterBoxLayout - a layout manager arranging actors as
1082 » Remove the requirement for the backend-specific implementation
1083 of ClutterStage to be a ClutterActor: a Stage implementation must
1084 only implement the ClutterStageWindow interface. This cleans up
1087 » COGL source tree clean up and rationalization; COGL now
1088 knows the platform, and not only the driver (GL or GLES) so
1089 we can migrate part of the low-level backend code from Clutter
1090 to COGL where it makes sense.
1092 » Remove code duplication across whole COGL.
1094 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
1095 have been fixed and confirmed working.
1097 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
1098 dumps the contents of each pick() buffer into a PNG file, for
1101 » Allow interpolating intervals of ClutterUnits for animating
1102 unit-based properties.
1104 » Increase strictness and correctness of the ClutterUnits
1107 » Add GValue transformation functions for ClutterPath to and
1110 » Fix word movement in ClutterText; implement GObject getter for
1111 :use-markup; emit notification for :position; decouple the
1112 :text property from the :use-markup property.
1114 » Do not queue redraws or relayouts on actors currently being
1117 » Support #rrggbb and #rgb notations for ClutterColor.
1119 » Multiple bug fixes.
1121 » Provide _NET_WM_PID on the X11 stage implementation.
1123 » Documentation and Introspection annotation fixes.
1125 » Add test units for the ClutterActor size requesition.
1129 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
1130 back to Shave on older Automake versions.
1150 Clutter 1.0.0 (28/07/2009)
1151 ===============================================================================
1153 • List of changes since 0.9.8
1155 » Allow per-stage disabling of motion event throttling; this should allow
1156 platforms or applications that require all the motion events not for
1157 drawing purposes to get them exactly like Clutter gets them from the
1160 » Various documentation fixes.
1162 » Add per-word key navigation inside ClutterText.
1164 » Fix the RGB<->HLS conversion.
1166 » Various fixes for the OSX backend.
1168 » Various build-related fixes.
1176 Clutter 0.9.8 (17/07/2009)
1177 ===============================================================================
1179 • List of changes since 0.9.6
1181 » Add more introspection annotations for language bindings.
1183 » Fix a bug in clutter_animation_set_alpha(), which also broke the
1184 clutter_actor_animate_with_alpha() function.
1186 » Check if the stage requires a relayout before showing it; this fixes
1187 a bug in the X11-based backends, especially under compositing window
1188 managers, where a 640x480 window would flicker before the default
1189 stage was shown for the first time.
1191 » Performance fixes for Cogl.
1193 » Sliced textures were broken by the COGL journalling.
1195 » Use the redraw cycle when asynchronously loading textures from
1198 » Miscellaneous compilation fixes for the OS X and Windows backends.
1200 » Allow querying from within the paint function of an Actor whether
1201 the actor is currently being directly painted or by a Clone actor.
1203 » In the GLX backend, when using the non-implicit sync-to-vblank inside
1204 glXSwapBuffers(), call glFinish() to avoid potential tearing.
1214 Clutter 0.9.6 (01/07/2009)
1215 ===============================================================================
1217 • List of changes since 0.9.4:
1219 » Allow the manipulation of the actor's transformation matrix, so that is
1220 is possible to apply additional transformations in a way that is
1221 compatible with the transformations already applied by the scene graph.
1223 » Fix a race in the X11 backend that happened between resizing the stage
1224 drawable and the call to glViewport().
1226 » Merge the cogl-journal-batching branch; this branch implements batching
1227 the geometry of the elements of the scene graph before sending it to
1228 OpenGL, thus minimizing the number of state changes and improving the
1229 overall performance of Clutter-based applications.
1231 » Add more debugging states for Clutter and COGL, which allow the developer
1232 to track the state of the journal; to check the VBO fallback paths; to
1233 disable picking for reliable profiling; to disable software-side matrix
1234 transformations in favour of the driver/GPU ones.
1236 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
1237 semantics; applications that drop into raw GL are, though, ignoring all
1238 the caching performed by COGL and might incur in performance issues.
1240 » Fixed the :load-async and :load-data-async properties of Texture by
1241 removing the unneeded G_PARAM_CONSTRUCT flag.
1243 » Added an initial migration guide that shows the porting process from
1244 older releases of Clutter to the 1.0 API; the first chapter deals with
1245 the migration from ClutterEffect to the new implicit animations API.
1247 » Fixed MT-safety for the master clock.
1251 Ole André Vadla Ravnås
1254 Clutter 0.9.4 (19/06/2009)
1255 ===============================================================================
1257 • List of changes since 0.9.2:
1259 » Set the layout height in ClutterText, so that wrapping and ellipsization
1260 work correctly to fill all the allocated area.
1262 » Remove all the units-based API, and migrate all the positional and
1263 dimensional accessors to use floating point values when dealing with
1264 pixels. All the properties dealing with pixels now that a floating
1265 point value as well.
1267 » Add the ability to track wether an actor is going to be painted or not,
1268 using the "mapped" flag. This also allows Clutter to be more strict
1269 in the handling of the scenegraph, ensuring correctness and avoiding
1270 wasting resources on nodes that won't be painted.
1272 » Add debugging facilities for COGL, similar to those of Clutter; through
1273 them is also possible to have an on screen debugging mode that shows the
1274 boundaries of each rectangle sent to the GPU.
1276 » Rework "units" into real logical distance units that can be converted
1277 between millimeters, typographic points and ems into pixels.
1279 » Simplify the Animation class to avoid redundancy and the possibility
1280 of it going out of sync with the Timeline and Alpha instances it uses.
1282 » Move every operation into a single "master clock" source that advances
1283 the timelines, dispatches events and redraws the stages in a predictable
1284 sequence, thus avoiding unneeded redraws. The default is to follow the
1285 sync-to-vblank cycle, if it is supported by the drivers.
1287 » Cache the glyphs geometry into a vertex buffer object to avoid
1288 resubmitting too much information to the GPU.
1290 » Rework the behaviour of ClutterModel when a filter is applied.
1292 » Allow submitting premultiplied texture data; this removes the need
1293 for unpremultiplying data in CairoTexture.
1295 » Add a simple API for submitting blending and texture combining modes
1296 through a string description.
1298 » Move Timelines to pure time-based objects.
1300 » Lots of performance improvements.
1302 » Removal of all the deprecated API.
1304 » Removal of all the fixed point entry points.
1306 » Lots of documentation fixes - the coverage is now 99% of the exported
1307 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
1309 » Generate the GObject Introspection data for both Clutter and COGL
1312 » Build environment fixes.

1591 Clutter 0.9.0 (30/01/2009)
1592 ===============================================================================
1594 • List of changes between 0.8.6 and 0.9.0
1596 » ClutterText is a new actor allowing text display, text editing
1597 both in multi-line and single-line modes, and text selection using
1598 the pointer devices and the keyboard. ClutterText supercedes both
1599 ClutterLabel and ClutterEntry.
1600 » ClutterClone is a new actor that allows cloning of other actors,
1601 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
1602 » ClutterBindingPool is a new API that allows to easily add key bindings
1604 » ClutterAnimation is a new API for implicit animations, similar to
1605 the tweening API used in toolkits like jQuery, Tween and Flash. This
1606 new API supercedes the ClutterEffect API.
1607 » ClutterAlpha uses "animation modes" instead of raw function
1608 pointers; it is still possible to pass alpha functions. The alpha
1609 functions provided by Clutter have been removed from the public
1610 API. It is possible to register global alpha functions and use
1611 them though a logical id.
1612 » The interval of the ClutterAlpha:alpha property has been changed
1613 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
1614 the addition of "overshooting" easing modes.
1615 » COGL now supports backface culling.
1616 » The COGL-based Pango renderer is public API and it is accessible
1617 to developers. It is also possible to access the PangoContext used
1618 by Clutter in order to create PangoLayouts to render text.
1619 » The ClutterFixed API has been moved to COGL.
1620 » COGL does not depend on Clutter data types anymore.
1621 » The ClutterMedia interface has been overhauled: implementations
1622 now must only override the interface properties. The ranges of
1623 some properties have been changed to normalized values.
1624 » COGL now exposes only floating point entry points, and reserves
1625 the eventual conversion to fixed point only when needed. The
1626 fixed point type and macros are publicly available for developers
1627 concerned about floating point operations.
1628 » COGL has a new Vertex Attribues API that allows submitting an
1629 extensible number of vertex attributes to OpenGL in a way that
1630 does not require format conversions and allows fast re-use.
1631 » COGL has a new Material API that decouples paths from fills; it
1632 is possible to create an arbitrary path and fill it with a COGL
1633 texture. The Material API also allows setting multiple texture
1634 layers and defining the blend modes and colors.
1635 » ClutterTexture has the ability to use a worker thread to asynchronously
1636 load an image from a file, as long as the GLib threading support has
1637 been enabled prior to calling clutter_init().
1638 » Clutter now supports localization of the help output, and it
1639 also supports globally setting the text direction for non left to
1641 » ClutterCairoTexture is a new actor that allows using Cairo
1642 to draw on a ClutterTexture; since Cairo does not have an OpenGL
1643 backend, the drawing is not hardware accelerated.
1644 » Clutter has a unit testing suite, based on the GLib unit test
1645 framework, which can be used to track regressions.
1646 » A ClutterPath object has been added, and it is used by the
1647 BehaviourPath. The Path object allows defining paths using a set
1648 of coordinates and operations. A Path can be "painted" either using
1649 COGL primitives or using Cairo primitives, allowing an easier way
1650 to paint non-rectangular shaped actors.
1651 » ClutterInterval is a simple object, used by ClutterAnimation, that
1652 describes an interval between two values, and interpolates between
1653 the initial and final values of the interval.

1888 Clutter 0.7.2 (23/06/2008), "Kedoke"
1889 ===============================================================================
1891 • List of changes between 0.7.0 and 0.7.2
1893 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
1894 to TRUE the texture will return a preferred width maintaining the
1895 aspect ratio with the given height and a preferred height maintaining
1896 the aspect ratio with the given width. This allows to set the width or
1897 the height and have the texture automatically request the height or the
1898 width respectively while maintaining the aspect ratio of the original
1901 » Added XINPUT support on the X11 backends; this provides an initial
1902 support for multiple input devices. The API is X11-specific, and
1903 provides support for querying at run-time support for XINPUT, for
1904 getting a list of input devices and for getting the type of each

1925 Clutter 0.7.0 (13/06/2008), "Booska"
1926 ===============================================================================
1928 • List of changes between 0.6 and 0.7.0
1930 » COGL, the underlying GL abstraction layer in Clutter, has been
1931 completely rewritten from the ground up. Its no longer a conceptual
1932 hack but a documented, fully featured library pretty much in its
1933 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
1934 OpenGL ES 2.0, providing a smart uniform API over these libraries
1935 with various utility features such as texture tiling abstractions,
1936 paths and primitive rendering, FBO, shaders, etc.
1938 » Clutter now provides an experimental backend for the Apple(tm)
1939 iPhone and iPod Touch families of products.
1941 » The Windows platform is now natively supported instead of
1942 relying on the SDL libraries. The win32 backend is still
1945 » The X11 based backends now feature support for Actors that wrap
1946 external X drawables (i.e the texture-from-pixmap extension and
1949 » Clutter now seamlessly supports multiple stages on the backends
1950 that allow this feature.
1952 » The custom Pango renderer has been completely rewritten, now using
1953 the more modern and maintained PangoCairo (instead of FT2), and avoids
1954 nasty subclassing hacks, supports smooth fast scaling of text, has
1955 many edge case issues fixed and it still is very efficient (using
1956 a texture glyph cache). It is even a little bit faster.
1958 » Better texture support, timeline improvements, ClutterLabel and
1959 ClutterEntry improvements, and container child properties are among
1960 the new features - too many to fit in the NEWS file.
1964 » #358 - "window resizing doesn't show scaled stage"

2105 Clutter 0.5.4 (25/01/2008)
2106 ==========================
2108 • List of changes between 0.5.2 and 0.5.4
2110 » A clutter-x11-<major>.<minor> pkg-config file is installed along
2111 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
2112 ones, for libraries and applications depending on the X11-based
2113 backends (GLX and EGLX).
2115 » Textures are correctly unrealized before changing and freeing the
2118 » It is now possible to block the automatic call to clutter_main_quit()
2119 when closing the stage window using the frame controls by connecting
2120 an handler for the ::event signal on the Clutter stage and checking
2121 for the CLUTTER_DELETE event type and returning TRUE. This allows
2122 the usage of other main loops with GLib reactors (like Python's twisted)
2123 with Clutter without triggering assertions by closing the stage window.

2145 ==========================
2147 • List of changes between 0.5.0 and 0.5.2
2149 » ClutterModelDefault has been renamed to ClutterListModel
2151 » ClutterModel now has vector-based variants for append, prepend and
2152 insert methods; these methods are useful for bindings

2161 Clutter 0.5.0 (02/01/2008)
2162 ==========================
2164 • List of changes between 0.4.2 and 0.5.0
2166 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
2167 flag set will receive events from the underlying backend; the event
2168 propagation chain will be walked in two directions (from the actor to
2169 the top-level container and back) with the ability to block it in
2172 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
2174 » ClutterScore, an object for controlling timelines; using a score
2175 instance is possible to start multiple timelines at once, or start
2176 a timeline after another has emitted the ::complete signal.
2178 » ClutterScript, an object for parsing a scene from an external file or
2179 a buffer; the scene is described using JSON (JavaScript Object Notation):
2180 every object is defined using its class and properties, and container
2181 objects can have their children defined as well. It is also possible
2182 do describe top-level objects such as timelines and behaviours, and to
2183 automatically connect signal handlers to signal names.
2185 » ClutterTimelines duration can now be set in milliseconds using the
2186 :duration property; the default framerate will be used to compute the
2187 actual duration in frames. The default framerate will be set by the
2188 backend, and can be overridden by the application.
2190 » ClutterTimelines direction can now be set using the :direction
2191 property; a timeline can be set to proceed forward or backward,
2192 and the direction can also be change while the timeline is still
2195 » New, experimental OSX backend.
2197 » Build environment for MS VisualStudio 2005.
2199 » ClutterModel, a generic list-based model object that can be used to
2200 implement actors following the Model-Viewer-Controller design pattern.
2201 Clutter provides a default implementation of ClutterModel, called
2202 ClutterModelDefault and using the GSequence data structure from GLib
2203 to optimize insertion and look up.
2205 » Add the ability to grab pointer and keyboard events: if an actor
2206 is set to have a grab it'll be the only one receiving events until
2207 it releases the grab.
2209 » Add the ability for an actor to receive the key focus; an actor
2210 with key focus will always receive the key events, even if it did
2211 not acquire the keyboard grab.
2213 » It is now possible to set the GL "fog" (also known as "depth cueing")
2214 effect on the ClutterStage; if the fog is enabled, actors farther
2215 away from the view point will fade into the stage background color.
2217 » Each actor now has an "anchor point", a point defined in the actor's
2218 coordinate space that will be used as the origin when scaling and
2219 rotation transformations.
2221 » Every pixel-based API has been doubled with a corresponding
2222 ClutterUnits-based function (postfixed with a '-u'), for instance:
2224 clutter_actor_set_position() - clutter_actor_set_positionu()
2225 clutter_actor_set_size() - clutter_actor_set_sizeu()
2226 clutter_actor_set_depth() - clutter_actor_set_depthu()
2228 This allows sub-pixel precision and device independence.
2230 » The ClutterLabel actor now tries very hard to provide a sane
2231 default size, if no bounding box has been requested; this fixes
2232 the :alignment property and allows the addition of the :justify
2235 » The SDL backend can now be compiled under win32 with MingW; this
2236 backend is still marked as experimental.
2238 » The OSX backend allows the compilation of Clutter under OS X; this
2239 backend is experimental.

2337 has a padding. Margins and paddings are expressed in ClutterUnits,
2338 to ease the transition to the device independent units. You can use
2339 clutter_box_set_default_padding() if you want the same padding for

2387 Clutter 0.3 (29/06/2007)
2388 ========================
2390 • List of changes between 0.2.3 and 0.3
2391 » Clutter now supports both switchable windowing system and GL backends.
2392 Window systems supported include GLX, EGL and SDL.
2394 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2395 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2396 yet documented - usage external to Clutter is not yet advised.
2398 Backends may provide specific command line options.
2404 The GLX backend is built by default and is currently the most
2405 developed, supported and featured windowing system backend. Only
2406 OpenGL is supported via GLX.
2410 Clutter has experimental support for using SDL. Open GL is supported as
2411 is OpenGL ES via Dogles (very experimental).
2415 Clutter has experimental support for using EGL. Only Open GL ES
2416 is supported by EGL.
2418 EGL support assumes an EGL implementation running atop X Windows.
2423 Clutter now has experimental support for Open GL ES.
2424 Current known issues;
2426 + Unrealising a ClutterTexture will not move pixel data from video
2427 into system memory but simply destroy it.
2428 + BGRA, YUV Texture data not currently supported.
2430 (Use the clutter_feature API to probe for above at runtime)
2432 Open Source ES implementations this has been tested against
2433 include `Vincent' and `dgles'. Support for commerical
2434 implementations may require modifications to the configure.ac

2438 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2440 dgles: http://developer.hybrid.fi/dgles/index.html
2442 » New ClutterEffect class provides a simplified (and thus less flexible)
2443 API wrapping around behaviours, alphas and timelines.
2444 » New Behaviours - bspline, ellipsis, rotation.
2445 » New built in Alpha functions;
2446 CLUTTER_ALPHA_SINE_INC
2447 CLUTTER_ALPHA_SINE_DEC
2448 CLUTTER_ALPHA_SINE_HALF
2449 CLUTTER_ALPHA_SQUARE

2465 » New Clutter_actor •project API calls allow for querying of tranformed
2466 actor vertices and points.
2467 » New Clutter Feature checks.
2468 » Initial ClutterUnit implementation for device independant positioning.
2469 • List of Bugs fixed

2502 Clutter 0.2 (18-01-2007)
2503 ========================
2505 • List of changes between 0.2 and 0.1
2506 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
2507 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
2508 » Actors now have an initial floating reference; this means you
2509 don't have to explicitely unref them: every memory an actor
2510 allocates will be freed when the group containing the actor will
2512 » Add basic run-time detection of GL features.
2513 + Use GL_TEXTURE_RECTANGLE_ARB if available.
2514 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2515 » Add API for behaviours. A ClutterBehaviour is an object which
2516 drives a set of actors using one or more properties depending
2517 on the value of an "alpha" function.
2518 + Provide simple behaviours: ClutterBehaviourOpacity,
2519 ClutterBehaviourPath and ClutterBehaviourScale.
2520 + Provide simple alpha functions for ramps and sine waveforms.
2521 » Add fixed point API for embedded platforms with no FPU.
2522 » Add support for command line switches to Clutter, like debug
2523 flags and abort on warnings; also allow application to hook up
2524 into the initialisation sequence to add their own command line
2526 » Add Pango GL renderer for Clutter, and use it to render text
2527 inside the ClutterLabel actor; this decrease texture memory
2529 » Redo Clutter Label widget, using the new Pango renderer.
2530 » Clutter Textures do not store local pixbuf copy (of texture).
2531 » Redo group and actor scale/sizing API and functionality.
2532 » Add memory management API for ClutterColor, and string parsing.
