1 Clutter 1.6.0 2011-01-31
2 ===============================================================================
4 • List of changes since Clutter 1.5.14
6 » Remove more private symbols from the X11 backend.
8 » Add CLUTTER_BIND_POSITION and CLUTTER_BIND_SIZE values to the
9 ClutterBindCoordinate enumeration; these are short-hand values
10 for binding both X and Y, or width and height, instead of
11 requiring two ClutterBindConstraint instances.
13 » Clean up in the X11 backend to reduce indirection.
15 » Small clean ups in the Win32 backend.
17 » Make Shift+Backspace behave like Backspace in ClutterText.
19 » Emit the ::new-frame signal even on the first frame of
20 ClutterTimeline, to allow setting up the initial state of an
23 » Fix an invalid memory access in ClutterAnimator.
25 » Flush the per-framebuffer journal when switching between
28 » Generalize updating GLES2 uniforms.
30 » Add debug code for tracing clipping in Cogl.
32 » Improve the OSX event loop, re-using the same implementation
33 as GDK. Also, provide simple, core-like device support.
35 • Bugs fixed since Clutter 1.5.14
37 #2490 - OS X backend event loop improved
38 #2530 - animator: Animator uses key after freeing it
39 #2534 - Incorrect description of function 'clutter_actor_pop_internal'
40 #2535 - Add recipe about creating a composite actor

47 Clutter 1.5.14 2011-01-24
48 ===============================================================================
50 • List of changes since Clutter 1.5.12
52 » Allow getting the state modifiers from a ClutterClickAction.
54 » Fix ClutterDragAction to never leave the event delivery in
57 » Optimize state changes for texture and data states.
59 » Enable VBO support in Cogl for GLES2.
61 » Fix compilation on GLES1.1.
63 » Documentation fixes.
65 » ClutterGLXTexturePixmap has been deprecated; its parent class
66 ClutterX11TexturePixmap and the low level CoglTexturePixmapX11
67 API provide access to the same features.
69 » Be more resilient against timelines controlling the state of
70 other timelines during the clock tick.
72 » Provide defines for the windowing platforms, to allow portable
73 applications to include the correct header and select the
74 correct API depending on the target.
76 » Introduce a fast path for cogl_read_pixels() that uses the journal
77 to determine the position of a single pixel on the stage; this
78 fast path gracefully degrades to the usual render-based approach,
79 and should speed up picking considerably in the case of opaque
80 quads batched together.
82 » Support XInput axis data on valuator devices, and introduce XInput2
83 support for event translation and device hotplugging. The support
84 for XI and XI2 must still be explicitly enabled by the developer,
85 but it is now compiled in by default. It can be disabled at compile
86 time by passing --disable-xinput to the configure script.
88 » Clean up the unintentionally leaked internal symbols in the X11
91 » Allow defining the contents of the rows of a ListModel using
92 ClutterScript. This completes the ability to fully define a
93 ClutterListModel inside a UI definition file.

107 #2518, introspection: Add missing (out) annotations for get_color()
108 #2520, Add API to get modifier type in ClutterClickAction
109 #2522, ClutterDragAction might indefinitely disable motion events
110 #2524, It's possible to receive a new-frame signal after stopping
112 #2526, model: Fix some GObject-Introspection annotations
113 #2527, model: Change the column argument type to gint for
114 clutter_model_set_sort

128 makes Clutter more compliant to the X11 window manager
131 » Avoid state corruption in relayout cycles.
133 » Do not crash when destroying actors during CLUTTER_LEAVE events.
135 » Remove signal handlers when disposing constraints.
137 » Keep the pixel alignment for ClutterAlignConstraint.

146 » Do not assume CoglBitmaps are allocated to height * rowstride.
148 » Fix the core device list creation on X11.
150 » Avoid enabling blending in the Cogl journal, if possible.
152 » Documentation fixes.
154 » Build fixes for mixed autotools version environment.
156 » Improve the performance of getting the number of rows of a
159 » Don't use obsolete API internally.

187 up batches of primitives.
189 » Keep a cache of ARBfp programs indexed by the pipeline state that
190 led to their generation.
192 » Accept G_TYPE_DOUBLE values in ClutterShaderEffect uniforms.
194 » Update the Wayland client backend.
196 » Update the build for Windows.

210 ===============================================================================
212 • List of changes since Clutter 1.5.6
214 » Add a migration guide for code using Behaviours.
216 » Allow parsing rgb(), rgba(), hls() and hlsa() color definitions.
218 » Performance improvements for the ClutterX11TexturePixmap.
220 » For caching purposes, do not discard the Material or the compiled
221 shaders for Offscreen and Shader effects.
223 » Fix image height in 3D Cogl textures.
225 » Create a GLSL generation backend for materials, similar to the
226 ARBfp one; this backend is the default for GLES2.
228 » Use FBOs and cogl_read_pixels() to efficiently read back partial
231 » Various fixes in paint volumes computation and caching.
233 » Use the internal scene graph walk API to remove the map/unmap

250 Alexandre Quessy, Evan Nemerson, Elliot Smith
252 Clutter 1.5.6 2010-11-19
253 ===============================================================================
255 • List of changes since Clutter 1.5.4
257 » Deprecate ClutterBehaviour and its sub-classes: the same functionality
258 is available using the animation framework.
260 » Add ClutterSnapConstraint, a constraint implementation that snaps
261 together the edges of two actors.
263 » Add ClutterPathConstraint::node-reached.
265 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
266 not used internally any more, and since it's not integrated with
267 the master clock it's of relative use.
269 » Add a named, global color palette.
271 » Add the ClutterTimeline:reverse property, for automatically
272 reversing the direction of a timeline after the emission of
273 the ::completed signal.
275 » Performance improvements in the clip stack.
277 » Do not use pointer grabs in ClutterClickAction.
279 » Improve the internally used Cogl API for primitives, paths and
280 buffers; this is the first step towards Cogl 2.0.
282 » Allow using the COGL_DEBUG environment variable to disable the
285 » Plug a nasty infinite loop in the XSETTINGS implementation.
287 » Internally rename CoglMaterial to CoglPipeline; this should make
288 it clearer that the API refers to the state of the GPU pipeline.
290 » Add support for clipped redraws on EGL using the NOK_swap_region
295 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
297 » Update examples in the Cookbook.

335 of an actor's allocation to follow a ClutterPath.
337 » Plug some memory leaks.
339 » Fix build of the CEx100 and EGL backends.
341 » Fixes for the OSX backend.

357 Clutter 1.5.2 (04/10/2010)
358 ===============================================================================
360 • List of changes since Clutter 1.4.0
362 » Add API to ClutterActor to allow any actor to define its 3D paint
363 volume and its stage-relative 2D bounding box; the paint volume is
364 the 3D space occupied by an actor during the paint sequence. This
365 allows better sizing of the FBOs, and opens the door to scenegraph
366 culling and accurate clipped redraws. The mechanism is opt-in: actors
367 have to implement the get_paint_volume() virtual function. Callbacks
368 attached to the ::paint signal will also disable any culling and
369 clipped redraw in place internally.
371 » Plug a leak in ClutterActor by disposing all constraints.
373 » Rework the build system to be as non-recursive as possible; this should
374 speed up the build of Clutter, and makes the build layout easier to
375 understand and update.
377 » Remove the internal copy of JSON-GLib; the internal copy was falling
378 behind at a spectacular level, and it was actually making the build
379 rather complicated - also by adding an unwanted, but needed,
380 introspection data generation. The required JSON-GLib has also been
381 bumped to the new stable release, 0.12.0.
383 » Use g_object_install_properties() with GLib 2.26.
385 » Implement ClutterContainer::child-notify, which slipped through the
386 cracks of many development cycles without anyone noticing.
388 » Document and test clutter_actor_contains(), especially the corner
391 » Plug a leak in CoglTexture2DSliced.
393 » Plug a leak in ClutterAnimator's handling of timelines.
395 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
396 errors when the GLX pixmap is destroyed behind Cogl's back.
409 Clutter 1.4.0 (24/09/2010)
410 ===============================================================================
412 • List of changes since Clutter 1.3.14
414 » Add support for describing ClutterState states using ClutterAnimators
419 » Include ClutterConstraints into the allocation phase, to avoid layout
420 cycles and improve the performance.
422 » Add new recipes to the Cookbook to illustrate constraints-based
425 » Fix the request mode of ClutterBoxLayout.
427 » Fix the handling of transformations in ClutterOffscreenEffect.
429 » Documentation and introspection fixes.

445 • List of changes since Clutter 1.3.12
447 » Fix applying layout properties from ClutterScript definitions in case
448 of multiple children.
450 » Add a Clutter EGL backend for Intel CEx100 platforms.
452 » Add new recipes in the Cookbook:
453 - texture cross-fading
454 - ClutterScript definitions
457 - reusing complex animations
459 » Add methods to retrieve the clicked button and to force a release
462 » Documentation fixes in the API reference.
464 » Cache a full pick buffer and re-use it in case the scene does not change
467 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
469 » Allow detaching animations created with clutter_actor_animate().
471 » Depend on GObject-Introspection >= 0.9.5.
473 » Provide introspection data for the X11-specific API, like
474 ClutterX11TexturePixmap
476 » Use a template material for ClutterTexture to minimize the creation of
479 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
480 :x-drag-threshold and :y-drag-threshold.
482 » Allow disabling the -Bsymbolic flag when linking.
484 » Use gettext >= 0.17 to handle the localization.
486 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
487 a crash when dealing with clip stacks.
489 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
490 freeing the X11 Pixmap to avoid an error.
492 » Avoid regenerating the CoglMaterial programs too many times.
513 Clutter 1.3.12 (16/08/2010)

535 emission of the ::notify signal on property changes.
537 » Re-use the Cogl texture atlas for the CoglPango glyphs cache,
538 and improve the performance with large font sizes.
540 » Various fixes in the Materials comparison and inheritance.
542 » Add the ability to associate a user program to a material.
553 Clutter 1.3.10 (04/08/2010)
554 ===============================================================================
556 • List of changes since Clutter 1.3.8
558 » Fix a locale-dependent conversion from double to string when
559 generating ARBfp programs for the materials.
561 » Use the XKB extension on X11 platforms to convert between hardware
564 » Documentation fixes in the API reference.
566 » More recipes, with videos and full examples, in the Cookbook.
568 » Add localization support and initial translations of error messages
569 that might be visualized in a user interface.
571 » Improve debugging output.
573 » Fix build of the GLX backend on OSX.
575 » Multiple fixes to the native OSX backend.

615 » Add missing public functions from COGL headers.
617 » Fix GLES build after the Cogl material changes.
619 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
621 » Split the clutter_state_change() method into two:
622 clutter_state_set_state(), for animated state changes; and
623 clutter_state_warp_to_state() for immediate state changes.
625 » Documentation and introspection fixes.
639 Clutter 1.3.6 (30/06/2010)
640 ===============================================================================
642 • List of changes since Clutter 1.3.4
644 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
645 available, by using EXT_framebuffer_blit. Both mechanisms are also
646 throttled to avoid taking all resources when using them in a compositor
649 » Use (and cache) fragment shaders instead of texture combiners inside
650 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
651 to fixed functions depending on the level of support of the underlying
654 » Implement a new design for materials; this allows scaling up the
655 number of materials in a scene, and also makes copying materials
658 » Make Cogl materials responsible for depth testing, and add new
661 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
662 object instead of using the stencil buffer, or the scanline rasterizer
663 on platforms without a stencil buffer.
665 » Add ClutterDeformEffect, a base class for effects that deform an
666 actor's geometry when painting it; ClutterPageTurnEffect is an
667 implementation of a "page curl" deformation using the DeformEffect
670 » Always use scissoring when clipping, to reduce the amount of buffer
671 that has to be cleared.
673 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
674 a constructor property; the default remains fragment shader.
676 » Remove the button of the press event from the DragAction::drag-begin
677 and DragAction::drag-end signals. This is an API break from 1.3.4.
679 » Do not promote clipped redraws to full redraws.
681 » Improve the consistency of the default state name in ClutterState,
682 both in the API and in the serialization format.
684 » Fix a rounding error with the Text layout size.
686 » Add utility functions for CoglMatrix and CoglColor.
688 » Avoid a re-allocation cycle warning when resizing the surface of
689 a CairoTexture actor from within the allocate() implementation.
691 » Do not add the GL libraries for the EGL X11 backend.
693 » Add more checks for size of data passed to the shader types GValue
696 » Add width and height to the BindConstraint.
698 » Parse actions, constraints and effects inside an actor definition
701 » Merge the code of native and x11 backends for EGL into a single
702 backend; also allow creating GL context with the EGL backend.
704 » Use XSETTINGS to set up the backend configuration options, like
705 the font name, resolution, font options and double click options,
706 on X11; this also allows ClutterText actors created using the
707 default font name to be updated when the font name and options
708 change; similarly, this allows ClutterUnits to be updated when
709 the screen resolution changes.
711 » Implement the texture_from_pixmap extension support inside Cogl
712 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
714 » Documentation improvements in the API reference and in the cookbook.
716 » Use the -Bsymbolic-functions linker option on supported platforms
717 to avoid intra-library PLT jumps.
719 » Fix painting transparent stages on X11 using the :use-alpha property
722 » Fix emission of scroll events on Windows.
741 Clutter 1.3.4 (07/06/2010)
742 ===============================================================================
744 • List of changes since Clutter 1.3.2
746 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
747 way an actor paints itself.
749 » Clutter provides a base class for effects painting to an
750 offscreen buffer, and a base class for effects using the
751 GL programmable pipeline (through the GLSL shader language).
753 » Clutter also provides some simple, shader-based effects:
754 ClutterBlurEffect, ClutterColorizeEffect and
755 ClutterDesaturateEffect.
757 » Effects can be applied to any actor, and can also be stacked.
759 » Add ClutterClickAction, an action that provides "button-like"
760 semantics for any ClutterActor.
762 » ClutterDragAction now moves the actor to which it has been applied
763 by default, using a class handler for the ::drag-motion signal.
765 » Add the :pick-with-alpha property to ClutterTexture; this property
766 allows using the alpha channel of a texture when picking it.
768 » Regenerate the mipmaps on COGL textures when a texture is modified.
770 » Documentation and build fixes.
779 Clutter 1.3.2 (24/05/2010)

788 related to event handling.
790 » Add ClutterConstraint, a class for implementing business
791 logic related to sizing and positioning.
793 » ClutterDragAction is an Action sub-class that implements
794 signals and properties for dragging actors.
796 » ClutterAlignConstraint and ClutterBindConstraint are two
797 Constraint sub-classes that allow relative positioning
798 with fixed layout managers.
800 » Add ClutterState, an object for defining state transitions.
802 » Add ClutterBoxLayout:homogeneous property.
804 » Implement retained clip stacks.
806 » Support retained paths.
808 » Add an experimental vector3 API.
810 » Require GLib >= 2.18.
812 » Require Atk >= 1.7.
814 » Make ClutterActor implement AtkImplementor, and allow retrieving
815 an AtkObject from a ClutterActor.
817 » Improve ClutterText's Pango layout caching mechanism.
819 » Fix set up of the GLX_SGI_swap_control extension.
823 » Documentation fixes for Clutter and COGL.
825 » Fix the conformance test suite by executing every test unit in
828 » Add platform-dependent defines for Cogl.
830 » Update the MingW cross-compilation script.

865 of JSON-GLib to which we fall back in the absence of the system
868 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
878 Clutter 1.2.0 (02/03/2010)
879 ===============================================================================
881 • List of changes since Clutter 1.1.14
883 » Improve the Animator API for consistency, and the implementation
884 to match the intended behaviour, as documented

887 and let the GLX texture-from-pixmap actor take advantage of it
889 » Support any pixel format in cogl_read_pixels()
891 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
894 » Consistently use :min-width and :min-height inside the Stage to define

939 behavioural modifiers
941 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
942 actor using a ClutterFixedLayout manager will automatically benefit
945 » Fix the packing order of ClutterBox so that the convention of
946 first-in-first-painted is maintained
948 » Documentation fixes
956 Clutter 1.1.12 (16/02/2010)
957 ===============================================================================
959 • List of changes since Clutter 1.1.10
961 » Fix compilation on 64bit platforms
963 » Fix some races of the Stage resizing on X11
965 » Documentation fixes for Cogl: the coverage is now 100%
967 » Fix rounding errors in the preferred height of the ClutterText
970 » Remove redundant type checks in clutter_actor_get_paint_opacity()
972 » Add support for the GLX_INTEL_swap_event extension; when using this
973 extension on GLX the glXSwapBuffers() call becomes non-blocking and
974 Clutter will use an event to control the master clock.
976 » Improve consistency between ClutterBox and ClutterGroup.
978 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
979 Stage X window if the window was not created by Clutter itself
981 » Improve caching of GL constant values
983 » Optimize creating sub-textures of sub-textures
985 » Various fixes for the atlas and the journal
987 » Disable the atlas if FBOs are not supported
997 Clutter 1.1.10 (09/02/2010)
998 ===============================================================================
1000 • List of changes since Clutter 1.1.8
1002 » Fixed a regression in textures that caused all the textures to be
1003 drawn as white rectangles.
1005 » Fixed compilation with the Sun C compiler.
1007 » Use SSE2 instructions to premultiply RGBA images, if available.
1009 » Improve readability of ClutterActor::raise/::lower warnings.
1016 Clutter 1.1.8 (08/02/2010)
1017 ===============================================================================
1019 • List of changes since Clutter 1.1.6
1021 » Added ClutterAnimator, a class that allows defining complex
1022 implicit animations involving multiple actors and states; this
1023 class is mostly meant to be used through the ClutterScript
1024 definition format, but it provides a convenience C API for
1025 easily building animations.
1027 » New experimental COGL API to expose "hardware" buffers such as PBOs or
1028 drm surfaces. This API can be used, for instance, to make texture
1031 » Fixed the issues with resizable stages getting a 1x1 window with
1034 » Expose input devices for every event; by default, X11 and Windows
1035 backends expose the core devices only.
1037 » Add the ClutterStage:key-focus property, for key focus tracking.
1039 » Allow setting transformable value types in ClutterAnimation when
1040 calling clutter_animation_bind() and clutter_animation_update().
1042 » Delay the creation of the default Stage until clutter_stage_get_default()
1043 is actually called; this reduces the work of clutter_init().
1045 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
1047 » Improve the extendability of CoglTexture with internal backends.
1049 » Add implicit texture atlasing; Cogl will try to put every texture
1050 inside the same texture atlas by default, to avoid state changes
1051 in the driver and (hopefully) improve performance.
1053 » Fix notification of the cursor and selection changes in ClutterText;
1054 this improves the usage of Clutter from A11Y toolkits.
1056 » Do not wait for a frame if the system clock goes backwards.
1058 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
1060 » Documentation and build fixes.
1073 Clutter 1.1.6 (18/01/2010)
1074 ===============================================================================
1076 • List of changes since Clutter 1.1.4
1078 » Some fixes for the Win32 backend (bug #1905).
1080 » Profiling support via the UProf library. Configure with
1081 --enable-profile to get a report after each Clutter application is
1084 » Improved conformance tests with coverage reports via gcov.
1086 » ClutterTexture no longer tries to read back texture data into
1087 g_malloc'd memory on unrealize (bug #1842).
1089 » The CGL_• defines from cogl-defines.h have been removed. These
1090 should not have been used by any applications, but if they were
1091 being used then please replace them either with the Cogl enums or
1092 with the appropriate GL_• enum if you are using GL directly.
1094 » Added a delete-event signal to the stage.
1096 » Fix for using cogl_rectangle with different texture coordinates
1097 for multiple layers (bug #1937).
1099 » Fix for using stencil and depth buffers in FBOs on Intel drivers
1100 in Mesa (bug #1873).
1102 » Support for subtitles in ClutterMedia.
1104 » ClutterGLX will now use an RGB visual by default. For
1105 applications (and toolkit integration libraries) that want to
1106 enable the ClutterStage:use-alpha property there is a new
1107 function: clutter_x11_set_use_argb_visual().
1109 » Fix ClutterText to allow using Pango markup and attributes in
1110 the same actor (bug #1940).
1122 Clutter 1.1.4 (03/01/2010)
1123 ===============================================================================
1125 • List of changes since Clutter 1.1.2
1127 » Update the ClutterScript parser to be more resilient, and support
1128 constructor and ChildMeta properties. The parser also respects the
1129 order of the properties in the UI definitions when applying them,
1130 and will apply the properties of an Actor after building the scene
1133 » Simplified the implementation of LayoutManager sub-classes, and added
1134 support for animating a layout manager.
1136 » Allow short-circuiting some layout operations by setting a specific
1137 flag on ClutterActor.
1139 » Improve caching of the preferred size of a ClutterActor.
1141 » Allow declaring "internal children" for a ClutterContainer
1142 implementation: the memory management of these actors will be deferred
1143 entirely to the Container.
1145 » Let the ClutterStage honour the :opacity property and the alpha component
1146 of the stage color. This requires support in the Clutter backend used.
1148 » Improve Windows and OSX backends.
1150 » Simplify the feature detection code for OpenGL; this also reduced the
1151 required OpenGL version to 1.2.
1153 » Improve the matrix stack handling code. The matrices can be debugged by
1154 using the COGL_DEBUG environment variable, assuming that Clutter was
1155 compiled with the right configure-time switch.
1157 » Improve COGL API for draw buffers, and for offscreen buffer support.
1159 » Add support for text direction to ClutterActor.
1161 » Documentation, introspection and build fixes.
1178 Clutter 1.1.2 (23/10/2009)
1179 ===============================================================================
1181 • List of changes since Clutter 1.0
1183 » Add ClutterLayoutManager, an abstract proxy class for easily
1184 writing layout management policies; also add ClutterLayoutMeta,
1185 a class for storing layout properties.
1187 » Add ClutterBox, a generic container actor that relies on a
1188 ClutterLayoutManager instance to manage the layout of its
1191 » Add the following layout managers:
1193 - ClutterFixedLayout - a layout manager implementing the
1194 policy used by ClutterGroup
1196 - ClutterBinLayout - a layout manager for packing actors
1197 as layers inside the same area, with per-actor alignment
1199 - ClutterFlowLayout - a layout manager arranging actors as
1202 - ClutterBoxLayout - a layout manager arranging actors as
1205 » Remove the requirement for the backend-specific implementation
1206 of ClutterStage to be a ClutterActor: a Stage implementation must
1207 only implement the ClutterStageWindow interface. This cleans up
1210 » COGL source tree clean up and rationalization; COGL now
1211 knows the platform, and not only the driver (GL or GLES) so
1212 we can migrate part of the low-level backend code from Clutter
1213 to COGL where it makes sense.
1215 » Remove code duplication across whole COGL.
1217 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
1218 have been fixed and confirmed working.
1220 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
1221 dumps the contents of each pick() buffer into a PNG file, for
1224 » Allow interpolating intervals of ClutterUnits for animating
1225 unit-based properties.
1227 » Increase strictness and correctness of the ClutterUnits
1230 » Add GValue transformation functions for ClutterPath to and
1233 » Fix word movement in ClutterText; implement GObject getter for
1234 :use-markup; emit notification for :position; decouple the
1235 :text property from the :use-markup property.
1237 » Do not queue redraws or relayouts on actors currently being
1240 » Support #rrggbb and #rgb notations for ClutterColor.
1242 » Multiple bug fixes.
1244 » Provide _NET_WM_PID on the X11 stage implementation.
1246 » Documentation and Introspection annotation fixes.
1248 » Add test units for the ClutterActor size requesition.
1252 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
1253 back to Shave on older Automake versions.
1273 Clutter 1.0.0 (28/07/2009)
1274 ===============================================================================
1276 • List of changes since 0.9.8
1278 » Allow per-stage disabling of motion event throttling; this should allow
1279 platforms or applications that require all the motion events not for
1280 drawing purposes to get them exactly like Clutter gets them from the
1283 » Various documentation fixes.
1285 » Add per-word key navigation inside ClutterText.
1287 » Fix the RGB<->HLS conversion.
1289 » Various fixes for the OSX backend.
1291 » Various build-related fixes.
1299 Clutter 0.9.8 (17/07/2009)
1300 ===============================================================================
1302 • List of changes since 0.9.6
1304 » Add more introspection annotations for language bindings.
1306 » Fix a bug in clutter_animation_set_alpha(), which also broke the
1307 clutter_actor_animate_with_alpha() function.
1309 » Check if the stage requires a relayout before showing it; this fixes
1310 a bug in the X11-based backends, especially under compositing window
1311 managers, where a 640x480 window would flicker before the default
1312 stage was shown for the first time.
1314 » Performance fixes for Cogl.
1316 » Sliced textures were broken by the COGL journalling.
1318 » Use the redraw cycle when asynchronously loading textures from
1321 » Miscellaneous compilation fixes for the OS X and Windows backends.
1323 » Allow querying from within the paint function of an Actor whether
1324 the actor is currently being directly painted or by a Clone actor.
1326 » In the GLX backend, when using the non-implicit sync-to-vblank inside
1327 glXSwapBuffers(), call glFinish() to avoid potential tearing.
1337 Clutter 0.9.6 (01/07/2009)
1338 ===============================================================================
1340 • List of changes since 0.9.4:
1342 » Allow the manipulation of the actor's transformation matrix, so that is
1343 is possible to apply additional transformations in a way that is
1344 compatible with the transformations already applied by the scene graph.
1346 » Fix a race in the X11 backend that happened between resizing the stage
1347 drawable and the call to glViewport().
1349 » Merge the cogl-journal-batching branch; this branch implements batching
1350 the geometry of the elements of the scene graph before sending it to
1351 OpenGL, thus minimizing the number of state changes and improving the
1352 overall performance of Clutter-based applications.
1354 » Add more debugging states for Clutter and COGL, which allow the developer
1355 to track the state of the journal; to check the VBO fallback paths; to
1356 disable picking for reliable profiling; to disable software-side matrix
1357 transformations in favour of the driver/GPU ones.
1359 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
1360 semantics; applications that drop into raw GL are, though, ignoring all
1361 the caching performed by COGL and might incur in performance issues.
1363 » Fixed the :load-async and :load-data-async properties of Texture by
1364 removing the unneeded G_PARAM_CONSTRUCT flag.
1366 » Added an initial migration guide that shows the porting process from
1367 older releases of Clutter to the 1.0 API; the first chapter deals with
1368 the migration from ClutterEffect to the new implicit animations API.
1370 » Fixed MT-safety for the master clock.
1374 Ole André Vadla Ravnås
1377 Clutter 0.9.4 (19/06/2009)
1378 ===============================================================================
1380 • List of changes since 0.9.2:
1382 » Set the layout height in ClutterText, so that wrapping and ellipsization
1383 work correctly to fill all the allocated area.
1385 » Remove all the units-based API, and migrate all the positional and
1386 dimensional accessors to use floating point values when dealing with
1387 pixels. All the properties dealing with pixels now that a floating
1388 point value as well.
1390 » Add the ability to track wether an actor is going to be painted or not,
1391 using the "mapped" flag. This also allows Clutter to be more strict
1392 in the handling of the scenegraph, ensuring correctness and avoiding
1393 wasting resources on nodes that won't be painted.
1395 » Add debugging facilities for COGL, similar to those of Clutter; through
1396 them is also possible to have an on screen debugging mode that shows the
1397 boundaries of each rectangle sent to the GPU.
1399 » Rework "units" into real logical distance units that can be converted
1400 between millimeters, typographic points and ems into pixels.
1402 » Simplify the Animation class to avoid redundancy and the possibility
1403 of it going out of sync with the Timeline and Alpha instances it uses.
1405 » Move every operation into a single "master clock" source that advances
1406 the timelines, dispatches events and redraws the stages in a predictable
1407 sequence, thus avoiding unneeded redraws. The default is to follow the
1408 sync-to-vblank cycle, if it is supported by the drivers.
1410 » Cache the glyphs geometry into a vertex buffer object to avoid
1411 resubmitting too much information to the GPU.
1413 » Rework the behaviour of ClutterModel when a filter is applied.
1415 » Allow submitting premultiplied texture data; this removes the need
1416 for unpremultiplying data in CairoTexture.
1418 » Add a simple API for submitting blending and texture combining modes
1419 through a string description.
1421 » Move Timelines to pure time-based objects.
1423 » Lots of performance improvements.
1425 » Removal of all the deprecated API.
1427 » Removal of all the fixed point entry points.
1429 » Lots of documentation fixes - the coverage is now 99% of the exported
1430 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
1432 » Generate the GObject Introspection data for both Clutter and COGL
1435 » Build environment fixes.

1714 Clutter 0.9.0 (30/01/2009)
1715 ===============================================================================
1717 • List of changes between 0.8.6 and 0.9.0
1719 » ClutterText is a new actor allowing text display, text editing
1720 both in multi-line and single-line modes, and text selection using
1721 the pointer devices and the keyboard. ClutterText supercedes both
1722 ClutterLabel and ClutterEntry.
1723 » ClutterClone is a new actor that allows cloning of other actors,
1724 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
1725 » ClutterBindingPool is a new API that allows to easily add key bindings
1727 » ClutterAnimation is a new API for implicit animations, similar to
1728 the tweening API used in toolkits like jQuery, Tween and Flash. This
1729 new API supercedes the ClutterEffect API.
1730 » ClutterAlpha uses "animation modes" instead of raw function
1731 pointers; it is still possible to pass alpha functions. The alpha
1732 functions provided by Clutter have been removed from the public
1733 API. It is possible to register global alpha functions and use
1734 them though a logical id.
1735 » The interval of the ClutterAlpha:alpha property has been changed
1736 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
1737 the addition of "overshooting" easing modes.
1738 » COGL now supports backface culling.
1739 » The COGL-based Pango renderer is public API and it is accessible
1740 to developers. It is also possible to access the PangoContext used
1741 by Clutter in order to create PangoLayouts to render text.
1742 » The ClutterFixed API has been moved to COGL.
1743 » COGL does not depend on Clutter data types anymore.
1744 » The ClutterMedia interface has been overhauled: implementations
1745 now must only override the interface properties. The ranges of
1746 some properties have been changed to normalized values.
1747 » COGL now exposes only floating point entry points, and reserves
1748 the eventual conversion to fixed point only when needed. The
1749 fixed point type and macros are publicly available for developers
1750 concerned about floating point operations.
1751 » COGL has a new Vertex Attribues API that allows submitting an
1752 extensible number of vertex attributes to OpenGL in a way that
1753 does not require format conversions and allows fast re-use.
1754 » COGL has a new Material API that decouples paths from fills; it
1755 is possible to create an arbitrary path and fill it with a COGL
1756 texture. The Material API also allows setting multiple texture
1757 layers and defining the blend modes and colors.
1758 » ClutterTexture has the ability to use a worker thread to asynchronously
1759 load an image from a file, as long as the GLib threading support has
1760 been enabled prior to calling clutter_init().
1761 » Clutter now supports localization of the help output, and it
1762 also supports globally setting the text direction for non left to
1764 » ClutterCairoTexture is a new actor that allows using Cairo
1765 to draw on a ClutterTexture; since Cairo does not have an OpenGL
1766 backend, the drawing is not hardware accelerated.
1767 » Clutter has a unit testing suite, based on the GLib unit test
1768 framework, which can be used to track regressions.
1769 » A ClutterPath object has been added, and it is used by the
1770 BehaviourPath. The Path object allows defining paths using a set
1771 of coordinates and operations. A Path can be "painted" either using
1772 COGL primitives or using Cairo primitives, allowing an easier way
1773 to paint non-rectangular shaped actors.
1774 » ClutterInterval is a simple object, used by ClutterAnimation, that
1775 describes an interval between two values, and interpolates between
1776 the initial and final values of the interval.

2012 ===============================================================================
2014 • List of changes between 0.7.0 and 0.7.2
2016 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
2017 to TRUE the texture will return a preferred width maintaining the
2018 aspect ratio with the given height and a preferred height maintaining
2019 the aspect ratio with the given width. This allows to set the width or
2020 the height and have the texture automatically request the height or the
2021 width respectively while maintaining the aspect ratio of the original
2024 » Added XINPUT support on the X11 backends; this provides an initial
2025 support for multiple input devices. The API is X11-specific, and
2026 provides support for querying at run-time support for XINPUT, for
2027 getting a list of input devices and for getting the type of each

2048 Clutter 0.7.0 (13/06/2008), "Booska"
2049 ===============================================================================
2051 • List of changes between 0.6 and 0.7.0
2053 » COGL, the underlying GL abstraction layer in Clutter, has been
2054 completely rewritten from the ground up. Its no longer a conceptual
2055 hack but a documented, fully featured library pretty much in its
2056 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
2057 OpenGL ES 2.0, providing a smart uniform API over these libraries
2058 with various utility features such as texture tiling abstractions,
2059 paths and primitive rendering, FBO, shaders, etc.
2061 » Clutter now provides an experimental backend for the Apple(tm)
2062 iPhone and iPod Touch families of products.
2064 » The Windows platform is now natively supported instead of
2065 relying on the SDL libraries. The win32 backend is still
2068 » The X11 based backends now feature support for Actors that wrap
2069 external X drawables (i.e the texture-from-pixmap extension and
2072 » Clutter now seamlessly supports multiple stages on the backends
2073 that allow this feature.
2075 » The custom Pango renderer has been completely rewritten, now using
2076 the more modern and maintained PangoCairo (instead of FT2), and avoids
2077 nasty subclassing hacks, supports smooth fast scaling of text, has
2078 many edge case issues fixed and it still is very efficient (using
2079 a texture glyph cache). It is even a little bit faster.
2081 » Better texture support, timeline improvements, ClutterLabel and
2082 ClutterEntry improvements, and container child properties are among
2083 the new features - too many to fit in the NEWS file.

2159 Clutter 0.6.0 (18/02/2008)
2160 ==========================
2162 • List of changes between 0.5.6 and 0.6.0
2164 » New documentation sections inside the API reference, describing
2165 the animation framework.
2167 » New API in ClutterActor for computing the actor's vertices in
2168 the plane of a given ancestor and accessors to query whether an
2169 actor is scaled or rotated

2178 Clutter 0.5.6 (11/02/2008)
2179 ==========================
2181 • List of changes between 0.5.4 and 0.5.6
2183 » Reverted a last minute change in the depth sorting function of
2186 » Added the clutter_actor_move_anchor_point() family of functions,
2187 which will set the anchor point at the given coordinates while
2188 adjusting the actor postion so that the relative position of the
2189 actor toward its parent remains the same.
2191 » Provide a fallback for finding the Clutter alpha functions inside
2192 a UI definition for ClutterScript in case g_module_open() fails.
2194 » Add initial Frame Buffer Objects support in ClutterTexture; using
2195 FBOs, where supported by the hardware and drivers, it's possible to
2196 create a ClutterTexture from any actor.
2198 • List of bugs fixed
2200 » #386 - Stage is white unless a timeline is present

2228 Clutter 0.5.4 (25/01/2008)
2229 ==========================
2231 • List of changes between 0.5.2 and 0.5.4
2233 » A clutter-x11-<major>.<minor> pkg-config file is installed along
2234 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
2235 ones, for libraries and applications depending on the X11-based
2236 backends (GLX and EGLX).
2238 » Textures are correctly unrealized before changing and freeing the
2241 » It is now possible to block the automatic call to clutter_main_quit()
2242 when closing the stage window using the frame controls by connecting
2243 an handler for the ::event signal on the Clutter stage and checking
2244 for the CLUTTER_DELETE event type and returning TRUE. This allows
2245 the usage of other main loops with GLib reactors (like Python's twisted)
2246 with Clutter without triggering assertions by closing the stage window.
2248 • List of bugs fixed
2250 » #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]

2267 Clutter 0.5.2 (14/01/2008)
2268 ==========================
2270 • List of changes between 0.5.0 and 0.5.2
2272 » ClutterModelDefault has been renamed to ClutterListModel
2274 » ClutterModel now has vector-based variants for append, prepend and
2275 insert methods; these methods are useful for bindings

2279 • List of bugs fixed
2281 » #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
2282 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
2284 Clutter 0.5.0 (02/01/2008)
2285 ==========================
2287 • List of changes between 0.4.2 and 0.5.0
2289 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
2290 flag set will receive events from the underlying backend; the event
2291 propagation chain will be walked in two directions (from the actor to
2292 the top-level container and back) with the ability to block it in
2295 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
2297 » ClutterScore, an object for controlling timelines; using a score
2298 instance is possible to start multiple timelines at once, or start
2299 a timeline after another has emitted the ::complete signal.
2301 » ClutterScript, an object for parsing a scene from an external file or
2302 a buffer; the scene is described using JSON (JavaScript Object Notation):
2303 every object is defined using its class and properties, and container
2304 objects can have their children defined as well. It is also possible
2305 do describe top-level objects such as timelines and behaviours, and to
2306 automatically connect signal handlers to signal names.
2308 » ClutterTimelines duration can now be set in milliseconds using the
2309 :duration property; the default framerate will be used to compute the
2310 actual duration in frames. The default framerate will be set by the
2311 backend, and can be overridden by the application.
2313 » ClutterTimelines direction can now be set using the :direction
2314 property; a timeline can be set to proceed forward or backward,
2315 and the direction can also be change while the timeline is still
2318 » New, experimental OSX backend.
2320 » Build environment for MS VisualStudio 2005.
2322 » ClutterModel, a generic list-based model object that can be used to
2323 implement actors following the Model-Viewer-Controller design pattern.
2324 Clutter provides a default implementation of ClutterModel, called
2325 ClutterModelDefault and using the GSequence data structure from GLib
2326 to optimize insertion and look up.
2328 » Add the ability to grab pointer and keyboard events: if an actor
2329 is set to have a grab it'll be the only one receiving events until
2330 it releases the grab.
2332 » Add the ability for an actor to receive the key focus; an actor
2333 with key focus will always receive the key events, even if it did
2334 not acquire the keyboard grab.
2336 » It is now possible to set the GL "fog" (also known as "depth cueing")
2337 effect on the ClutterStage; if the fog is enabled, actors farther
2338 away from the view point will fade into the stage background color.
2340 » Each actor now has an "anchor point", a point defined in the actor's
2341 coordinate space that will be used as the origin when scaling and
2342 rotation transformations.
2344 » Every pixel-based API has been doubled with a corresponding
2345 ClutterUnits-based function (postfixed with a '-u'), for instance:
2347 clutter_actor_set_position() - clutter_actor_set_positionu()
2348 clutter_actor_set_size() - clutter_actor_set_sizeu()
2349 clutter_actor_set_depth() - clutter_actor_set_depthu()
2351 This allows sub-pixel precision and device independence.
2353 » The ClutterLabel actor now tries very hard to provide a sane
2354 default size, if no bounding box has been requested; this fixes
2355 the :alignment property and allows the addition of the :justify
2358 » The SDL backend can now be compiled under win32 with MingW; this
2359 backend is still marked as experimental.
2361 » The OSX backend allows the compilation of Clutter under OS X; this
2362 backend is experimental.

2460 has a padding. Margins and paddings are expressed in ClutterUnits,
2461 to ease the transition to the device independent units. You can use

2510 Clutter 0.3 (29/06/2007)
2511 ========================
2513 • List of changes between 0.2.3 and 0.3
2514 » Clutter now supports both switchable windowing system and GL backends.
2515 Window systems supported include GLX, EGL and SDL.
2517 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2518 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2519 yet documented - usage external to Clutter is not yet advised.
2521 Backends may provide specific command line options.
2527 The GLX backend is built by default and is currently the most
2528 developed, supported and featured windowing system backend. Only
2529 OpenGL is supported via GLX.
2533 Clutter has experimental support for using SDL. Open GL is supported as
2534 is OpenGL ES via Dogles (very experimental).
2538 Clutter has experimental support for using EGL. Only Open GL ES
2539 is supported by EGL.
2541 EGL support assumes an EGL implementation running atop X Windows.
2546 Clutter now has experimental support for Open GL ES.
2547 Current known issues;
2549 + Unrealising a ClutterTexture will not move pixel data from video
2550 into system memory but simply destroy it.
2551 + BGRA, YUV Texture data not currently supported.
2553 (Use the clutter_feature API to probe for above at runtime)
2555 Open Source ES implementations this has been tested against
2556 include `Vincent' and `dgles'. Support for commerical
2557 implementations may require modifications to the configure.ac
2560 vincent: http://ogl-es.sourceforge.net/
2561 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2563 dgles: http://developer.hybrid.fi/dgles/index.html
2565 » New ClutterEffect class provides a simplified (and thus less flexible)
2566 API wrapping around behaviours, alphas and timelines.
2567 » New Behaviours - bspline, ellipsis, rotation.
2568 » New built in Alpha functions;
2569 CLUTTER_ALPHA_SINE_INC
2570 CLUTTER_ALPHA_SINE_DEC
2571 CLUTTER_ALPHA_SINE_HALF
2572 CLUTTER_ALPHA_SQUARE

2588 » New Clutter_actor •project API calls allow for querying of tranformed
2589 actor vertices and points.
2590 » New Clutter Feature checks.
2591 » Initial ClutterUnit implementation for device independant positioning.
2592 • List of Bugs fixed

2622 • List of bugs fixed
2623 » #215 - macro CLUTTER_MARK() not disabled for non-debug builds
2625 Clutter 0.2 (18-01-2007)
2626 ========================
2628 • List of changes between 0.2 and 0.1
2629 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
2630 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
2631 » Actors now have an initial floating reference; this means you
2632 don't have to explicitely unref them: every memory an actor
2633 allocates will be freed when the group containing the actor will
2635 » Add basic run-time detection of GL features.
2636 + Use GL_TEXTURE_RECTANGLE_ARB if available.
2637 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2638 » Add API for behaviours. A ClutterBehaviour is an object which
2639 drives a set of actors using one or more properties depending
2640 on the value of an "alpha" function.
2641 + Provide simple behaviours: ClutterBehaviourOpacity,
2642 ClutterBehaviourPath and ClutterBehaviourScale.
2643 + Provide simple alpha functions for ramps and sine waveforms.
2644 » Add fixed point API for embedded platforms with no FPU.
2645 » Add support for command line switches to Clutter, like debug
2646 flags and abort on warnings; also allow application to hook up
2647 into the initialisation sequence to add their own command line
2649 » Add Pango GL renderer for Clutter, and use it to render text
2650 inside the ClutterLabel actor; this decrease texture memory
2652 » Redo Clutter Label widget, using the new Pango renderer.
2653 » Clutter Textures do not store local pixbuf copy (of texture).
2654 » Redo group and actor scale/sizing API and functionality.
2655 » Add memory management API for ClutterColor, and string parsing.
