59 * List of changes between 0.7.2 and 0.7.4
61 o Fix the ClutterEntry actor after the clip API changes in COGL.
63 o Update the shaders generated for GLES 2.0.

69 o Fix the GLES 1.1 support.
71 o Warn if no usable pointer device are available on X11 backends.
73 o Improve the request for the best pixel format on win32.
75 o Fix a regression when sizing the ClutterStage on backends that
76 only support fixed size stages; now setting any size will result
77 in Clutter ignoring the request, like it happened in Clutter 0.6.
79 o Add a method to ClutterBackend to retrieve the display size.
81 o Fix clutter_sinx() for angles > CFX_2PI - CFX_ONE.

93 Clutter 0.7.2 (23/06/2008), "Kedoke"
94 ===============================================================================
96 * List of changes between 0.7.0 and 0.7.2
98 o ClutterTexture has a new :keep-aspect-ratio property; when it is set
99 to TRUE the texture will return a preferred width maintaining the
100 aspect ratio with the given height and a preferred height maintaining
101 the aspect ratio with the given width. This allows to set the width or
102 the height and have the texture automatically request the height or the
103 width respectively while maintaining the aspect ratio of the original
106 o Added XINPUT support on the X11 backends; this provides an initial
107 support for multiple input devices. The API is X11-specific, and
108 provides support for querying at run-time support for XINPUT, for
109 getting a list of input devices and for getting the type of each
112 o The 'fruity' backend also features multiple device support.
116 o #816 - clutter_actor_request_coords() should take a const box.
117 o #836 - Optimize clutter_label_query_coords()
118 o #905 - Paint cursor directly

127 o #982 - __COGL_GET_CONTEXT MS compiler issue
128 o #984 - pango_clutter_render_layout() declared void
130 Clutter 0.7.0 (13/06/2008), "Booska"
131 ===============================================================================
133 * List of changes between 0.6 and 0.7.0
135 o COGL, the underlying GL abstraction layer in Clutter, has been
136 completely rewritten from the ground up. Its no longer a conceptual
137 hack but a documented, fully featured library pretty much in its
138 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
139 OpenGL ES 2.0, providing a smart uniform API over these libraries
140 with various utility features such as texture tiling abstractions,
141 paths and primitive rendering, FBO, shaders, etc.
143 o Clutter now provides an experimental backend for the Apple(tm)
144 iPhone and iPod Touch families of products.
146 o The Windows platform is now natively supported instead of
147 relying on the SDL libraries. The win32 backend is still
150 o The X11 based backends now feature support for Actors that wrap
151 external X drawables (i.e the texture-from-pixmap extension and
154 o Clutter now seamlessly supports multiple stages on the backends
155 that allow this feature.
157 o The custom Pango renderer has been completely rewritten, now using
158 the more modern and maintained PangoCairo (instead of FT2), and avoids
159 nasty subclassing hacks, supports smooth fast scaling of text, has
160 many edge case issues fixed and it still is very efficient (using
161 a texture glyph cache). It is even a little bit faster.
163 o Better texture support, timeline improvements, ClutterLabel and
164 ClutterEntry improvements, and container child properties are among
165 the new features - too many to fit in the NEWS file.
169 o #358 - "window resizing doesn't show scaled stage"
170 o #425 - "COGL enhancements"
171 o #439 - "timing related pong lockup due to timeline_rewind somtimes
172 being ignored by timeline_timeout_func"

244 * List of changes between 0.5.6 and 0.6.0
246 o New documentation sections inside the API reference, describing
247 the animation framework.
249 o New API in ClutterActor for computing the actor's vertices in
250 the plane of a given ancestor and accessors to query whether an
251 actor is scaled or rotated
255 o #613 - Extend point transformation API
256 o #779 - Rounding error in ClutterBehaviourScale [Havoc Pennington]
257 o #787 - tiled textures are broken
258 o #796 - segmentation fault when setting label text
260 Clutter 0.5.6 (11/02/2008)
261 ==========================
263 * List of changes between 0.5.4 and 0.5.6
265 o Reverted a last minute change in the depth sorting function of
268 o Added the clutter_actor_move_anchor_point() family of functions,
269 which will set the anchor point at the given coordinates while
270 adjusting the actor postion so that the relative position of the
271 actor toward its parent remains the same.
273 o Provide a fallback for finding the Clutter alpha functions inside
274 a UI definition for ClutterScript in case g_module_open() fails.
276 o Add initial Frame Buffer Objects support in ClutterTexture; using
277 FBOs, where supported by the hardware and drivers, it's possible to
278 create a ClutterTexture from any actor.
282 o #386 - Stage is white unless a timeline is present
283 o #439 - timing related pong lockup due to timeline rewind...
284 o #440 - 1 pixel line flickering
285 o #442 - Shader support
286 o #451 - Improve font rendering quality (Pango)
287 o #452 - Textures are shown with distortion on Solaris/SPARC

293 o #635 - Fix buffer overflow in clutter_texture_get_pixbuf() [Gwenole
295 o #643 - Superfluous "filter-quality" setting in texture_upload_data()?
297 o #689 - Rotating actor through layers does not handle opacity
298 correctly [Josh Stewart]
299 o #710 - Make "box-blur" test shader work in some way [Gwenole Beauchesne]
300 o #719 - X11 backend does not check window field in events [Havoc
302 o #724 - ClutterLabel reports wrong height when lines > 1
303 o #749 - "reactive" property does not change
304 o #751 - missing XSync in clutter-event-x11.c:xembed_set_info() [Havoc

310 Clutter 0.5.4 (25/01/2008)
311 ==========================
313 * List of changes between 0.5.2 and 0.5.4
315 o A clutter-x11-<major>.<minor> pkg-config file is installed along
316 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
317 ones, for libraries and applications depending on the X11-based
318 backends (GLX and EGLX).
320 o Textures are correctly unrealized before changing and freeing the
323 o It is now possible to block the automatic call to clutter_main_quit()
324 when closing the stage window using the frame controls by connecting
325 an handler for the ::event signal on the Clutter stage and checking
326 for the CLUTTER_DELETE event type and returning TRUE. This allows
327 the usage of other main loops with GLib reactors (like Python's twisted)
328 with Clutter without triggering assertions by closing the stage window.
332 o #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]
333 o #614 - ClutterActor API inconsistencies
334 o #640 - ClutterTexture unrealized with no GL context
335 o #654 - Under heavy load clutter sometimes drops the last frame of
336 a timeline [Johan Bilien]
337 o #672 - Event handling in osx backend is broken [Tommi Komulainen]
338 o #684 - Improve test-scale by also using anchor point [Jaap A. Haitsma]
339 o #695 - clutter-shader: Invalid format string for
340 gssize [Tommi Komulainen]
341 o #696 - cogl_get_proc_address requires GLX [Tommi Komulainen]
342 o #709 - clutter_effect_scale inconsistent with clutter_actor_set_scale
343 o #714 - clutter_event_copy for enter/leave event generates
344 extra unref [Neil Roberts]
345 o #715 - Type errors in test-shader
346 o #720 - BehaviourScale not working in python after recent
347 API change [Josh Stewart]
349 Clutter 0.5.2 (14/01/2008)
350 ==========================
352 * List of changes between 0.5.0 and 0.5.2
354 o ClutterModelDefault has been renamed to ClutterListModel
356 o ClutterModel now has vector-based variants for append, prepend and
357 insert methods; these methods are useful for bindings
359 o Add units-based variant for clutter_actor_move_by()
363 o #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
364 o #700 - Fix for clutter_effect_rotate() [Neil Roberts]
366 Clutter 0.5.0 (02/01/2008)
367 ==========================
369 * List of changes between 0.4.2 and 0.5.0
371 o New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
372 flag set will receive events from the underlying backend; the event
373 propagation chain will be walked in two directions (from the actor to
374 the top-level container and back) with the ability to block it in
377 o ClutterShader, an abstraction over the programmable OpenGL pipeline.
379 o ClutterScore, an object for controlling timelines; using a score
380 instance is possible to start multiple timelines at once, or start
381 a timeline after another has emitted the ::complete signal.
383 o ClutterScript, an object for parsing a scene from an external file or
384 a buffer; the scene is described using JSON (JavaScript Object Notation):
385 every object is defined using its class and properties, and container
386 objects can have their children defined as well. It is also possible
387 do describe top-level objects such as timelines and behaviours, and to
388 automatically connect signal handlers to signal names.
390 o ClutterTimelines duration can now be set in milliseconds using the
391 :duration property; the default framerate will be used to compute the
392 actual duration in frames. The default framerate will be set by the
393 backend, and can be overridden by the application.
395 o ClutterTimelines direction can now be set using the :direction
396 property; a timeline can be set to proceed forward or backward,
397 and the direction can also be change while the timeline is still
400 o New, experimental OSX backend.
402 o Build environment for MS VisualStudio 2005.
404 o ClutterModel, a generic list-based model object that can be used to
405 implement actors following the Model-Viewer-Controller design pattern.
406 Clutter provides a default implementation of ClutterModel, called
407 ClutterModelDefault and using the GSequence data structure from GLib
408 to optimize insertion and look up.
410 o Add the ability to grab pointer and keyboard events: if an actor
411 is set to have a grab it'll be the only one receiving events until
412 it releases the grab.
414 o Add the ability for an actor to receive the key focus; an actor
415 with key focus will always receive the key events, even if it did
416 not acquire the keyboard grab.
418 o It is now possible to set the GL "fog" (also known as "depth cueing")
419 effect on the ClutterStage; if the fog is enabled, actors farther
420 away from the view point will fade into the stage background color.
422 o Each actor now has an "anchor point", a point defined in the actor's
423 coordinate space that will be used as the origin when scaling and
424 rotation transformations.
426 o Every pixel-based API has been doubled with a corresponding
427 ClutterUnits-based function (postfixed with a '-u'), for instance:
429 clutter_actor_set_position() - clutter_actor_set_positionu()
430 clutter_actor_set_size() - clutter_actor_set_sizeu()
431 clutter_actor_set_depth() - clutter_actor_set_depthu()
433 This allows sub-pixel precision and device independence.
435 o The ClutterLabel actor now tries very hard to provide a sane
436 default size, if no bounding box has been requested; this fixes
437 the :alignment property and allows the addition of the :justify
440 o The SDL backend can now be compiled under win32 with MingW; this
441 backend is still marked as experimental.
443 o The OSX backend allows the compilation of Clutter under OS X; this
444 backend is experimental.
448 o #423 - All actors should emit events rather than just the stage
449 o #424 - Interface definition files

541 between the inner-border and the children); plus, each packed child
542 has a padding. Margins and paddings are expressed in ClutterUnits,
543 to ease the transition to the device independent units. You can use
544 clutter_box_set_default_padding() if you want the same padding for

562 Clutter 0.3.1 (06/07/2007)
563 ========================
565 * List of changes between 0.3 and 0.3.1
566 o EGL. There are now 2 experimental EGL backends;
567 - 'eglx', the former EGL on X11 implementation (now renamed)
568 - 'eglnative', a new EGL 'native' backend which supporting non
569 X11 EGL implementations (i.e framebuffer).
571 o ClutterGroup now returns correct size when a child is removed.
573 o Missing redhand.png added to distro tarball (fixing tests that require
576 o Fix picking in ClutterBox
578 o Rectangle border creation fixed.
580 o Fix overflow in Exponential Alpha funcs.
582 o Many API documentation fixes and improvements.
584 o ClutterEffect cleanups.
586 o ClutterEntry cleanups.
588 o Check for versioned XFixes library (GLX backend).
590 o More X error traps in GLX backend.
592 Clutter 0.3 (29/06/2007)
593 ========================
595 * List of changes between 0.2.3 and 0.3
596 o Clutter now supports both switchable windowing system and GL backends.
597 Window systems supported include GLX, EGL and SDL.
599 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
600 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
601 yet documented - usage external to Clutter is not yet advised.
603 Backends may provide specific command line options.
609 The GLX backend is built by default and is currently the most
610 developed, supported and featured windowing system backend. Only
611 OpenGL is supported via GLX.
615 Clutter has experimental support for using SDL. Open GL is supported as
616 is OpenGL ES via Dogles (very experimental).
620 Clutter has experimental support for using EGL. Only Open GL ES
623 EGL support assumes an EGL implementation running atop X Windows.
628 Clutter now has experimental support for Open GL ES.
629 Current known issues;
631 + Unrealising a ClutterTexture will not move pixel data from video
632 into system memory but simply destroy it.
633 + BGRA, YUV Texture data not currently supported.
635 (Use the clutter_feature API to probe for above at runtime)
637 Open Source ES implementations this has been tested against
638 include `Vincent' and `dgles'. Support for commerical
639 implementations may require modifications to the configure.ac

643 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
645 dgles: http://developer.hybrid.fi/dgles/index.html
647 o New ClutterEffect class provides a simplified (and thus less flexible)
648 API wrapping around behaviours, alphas and timelines.
649 o New Behaviours - bspline, ellipsis, rotation.
650 o New built in Alpha functions;
651 CLUTTER_ALPHA_SINE_INC
652 CLUTTER_ALPHA_SINE_DEC
653 CLUTTER_ALPHA_SINE_HALF
655 CLUTTER_ALPHA_SMOOTHSTEP_INC
656 CLUTTER_ALPHA_SMOOTHSTEP_DEC
657 CLUTTER_ALPHA_EXP_INC
658 CLUTTER_ALPHA_EXP_DEC
659 o New Actors and interfaces
660 + ClutterLayout, for writing extended layout support in actors
661 + ClutterContainer, for generic container actors
662 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
663 + ClutterEntry, text entry actor
664 o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
665 o All internal math now fixed point based.
666 o Clutter now has it own internal event queue.
667 o ClutterStage new features;
668 + Title property for naming in window decorations.
669 + Perspective setting - The stages perspective can now be modified.
670 o New Clutter_actor *project API calls allow for querying of tranformed
671 actor vertices and points.
672 o New Clutter Feature checks.
673 o Initial ClutterUnit implementation for device independant positioning.
675 o Various issues with very poor performance and Intel drivers.
676 o #138 Fix typo in x rotation transform.
678 Clutter 0.2.3 (2007-04-11)
679 ==========================
681 * List of changed between 0.2.2 and 0.2.3
682 o Fixes to tile based textures and again clutter_texture_get_pixbuf(). [Matthew]
683 o Implement Gravity for ClutterScaleBehaviour. [Matthew, Rob]
685 Clutter 0.2.2 (2007-03-22)
686 ==========================
688 * List of changed between 0.2.1 and 0.2.2
689 o Addition of basic XEMBED support for clutter stage. [Matthew]
690 o Fixes to clutter_texture_get_pixbuf(). [Matthew]
691 o Export clutter_group_remove_all and add associated fixes. [Matthew]
693 Clutter 0.2.1 (2007-02-07)
694 ==========================
696 * List of changed between 0.2.0 and 0.2.1
697 o Add even faster double to integer (and back) conversion
699 o Fix some errors in the fixed point sine waveform
701 o Use fixed point math in the Pango renderer. [Tomas]
702 o Improve the GL version check. [Matthew]
703 o Add a square waveform function. [Emmanuele]
705 o #215 - macro CLUTTER_MARK() not disabled for non-debug builds
707 Clutter 0.2 (18-01-2007)
708 ========================
710 * List of changes between 0.2 and 0.1
711 o Bindings, GStreamer and GTK+ dependencies moved out of tree:
712 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
713 o Actors now have an initial floating reference; this means you
714 don't have to explicitely unref them: every memory an actor
715 allocates will be freed when the group containing the actor will
717 o Add basic run-time detection of GL features.
718 + Use GL_TEXTURE_RECTANGLE_ARB if available.
719 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
720 o Add API for behaviours. A ClutterBehaviour is an object which
721 drives a set of actors using one or more properties depending
722 on the value of an "alpha" function.
723 + Provide simple behaviours: ClutterBehaviourOpacity,
724 ClutterBehaviourPath and ClutterBehaviourScale.
725 + Provide simple alpha functions for ramps and sine waveforms.
726 o Add fixed point API for embedded platforms with no FPU.
727 o Add support for command line switches to Clutter, like debug
728 flags and abort on warnings; also allow application to hook up
729 into the initialisation sequence to add their own command line
731 o Add Pango GL renderer for Clutter, and use it to render text
732 inside the ClutterLabel actor; this decrease texture memory
734 o Redo Clutter Label widget, using the new Pango renderer.
735 o Clutter Textures do not store local pixbuf copy (of texture).
736 o Redo group and actor scale/sizing API and functionality.
737 o Add memory management API for ClutterColor, and string parsing.
739 o #199 - Little group handling fix?
740 o #198 - Detect NPOT support on more systems
741 o #197 - Tiled textures are broken
742 o #196 - Rebuild the examples when the library changes
743 o #156 - clutter_actor_set_position not using the absolute size
744 o #155 - Don't test for XInitThreads [Bastien Nocera]
745 o #154 - Key presses not working in super-oh example [Bastien Nocera]
746 o #152 - Misc fixes [Bastien Nocera]
747 o #143 - Faulty ref-counting in clutter_group_remove [Frederic Riss]
748 o #141 - Copy-pasto in clutter_media_set_volume [Frederic Riss]
749 o #101 - No package 'x11' found -- wrong configure [Tomasz Torcz]
750 o #98 - Enabling trails in super-oh crashes
