1 Clutter 0.9.8 (17/07/2009)
2 ===============================================================================
4 * List of changes since 0.9.6
6 o Add more introspection annotations for language bindings.
8 o Fix a bug in clutter_animation_set_alpha(), which also broke the
9 clutter_actor_animate_with_alpha() function.
11 o Check if the stage requires a relayout before showing it; this fixes
12 a bug in the X11-based backends, especially under compositing window
13 managers, where a 640x480 window would flicker before the default
14 stage was shown for the first time.
16 o Performance fixes for Cogl.
18 o Sliced textures were broken by the COGL journalling.
20 o Use the redraw cycle when asynchronously loading textures from
23 o Miscellaneous compilation fixes for the OS X and Windows backends.
25 o Allow querying from within the paint function of an Actor whether
26 the actor is currently being directly painted or by a Clone actor.
28 o In the GLX backend, when using the non-implicit sync-to-vblank inside
29 glXSwapBuffers(), call glFinish() to avoid potential tearing.
39 Clutter 0.9.6 (01/07/2009)
40 ===============================================================================
42 * List of changes since 0.9.4:
44 o Allow the manipulation of the actor's transformation matrix, so that is
45 is possible to apply additional transformations in a way that is
46 compatible with the transformations already applied by the scene graph.
48 o Fix a race in the X11 backend that happened between resizing the stage
49 drawable and the call to glViewport().
51 o Merge the cogl-journal-batching branch; this branch implements batching
52 the geometry of the elements of the scene graph before sending it to
53 OpenGL, thus minimizing the number of state changes and improving the
54 overall performance of Clutter-based applications.
56 o Add more debugging states for Clutter and COGL, which allow the developer
57 to track the state of the journal; to check the VBO fallback paths; to
58 disable picking for reliable profiling; to disable software-side matrix
59 transformations in favour of the driver/GPU ones.
61 o Improve the ability to "break out" of COGL by using gl_begin/gl_end
62 semantics; applications that drop into raw GL are, though, ignoring all
63 the caching performed by COGL and might incur in performance issues.
65 o Fixed the :load-async and :load-data-async properties of Texture by
66 removing the unneeded G_PARAM_CONSTRUCT flag.
68 o Added an initial migration guide that shows the porting process from
69 older releases of Clutter to the 1.0 API; the first chapter deals with
70 the migration from ClutterEffect to the new implicit animations API.
72 o Fixed MT-safety for the master clock.

79 Clutter 0.9.4 (19/06/2009)
80 ===============================================================================
82 * List of changes since 0.9.2:
84 o Set the layout height in ClutterText, so that wrapping and ellipsization
85 work correctly to fill all the allocated area.
87 o Remove all the units-based API, and migrate all the positional and
88 dimensional accessors to use floating point values when dealing with
89 pixels. All the properties dealing with pixels now that a floating
92 o Add the ability to track wether an actor is going to be painted or not,
93 using the "mapped" flag. This also allows Clutter to be more strict
94 in the handling of the scenegraph, ensuring correctness and avoiding
95 wasting resources on nodes that won't be painted.
97 o Add debugging facilities for COGL, similar to those of Clutter; through
98 them is also possible to have an on screen debugging mode that shows the
99 boundaries of each rectangle sent to the GPU.
101 o Rework "units" into real logical distance units that can be converted
102 between millimeters, typographic points and ems into pixels.
104 o Simplify the Animation class to avoid redundancy and the possibility
105 of it going out of sync with the Timeline and Alpha instances it uses.
107 o Move every operation into a single "master clock" source that advances
108 the timelines, dispatches events and redraws the stages in a predictable
109 sequence, thus avoiding unneeded redraws. The default is to follow the
110 sync-to-vblank cycle, if it is supported by the drivers.
112 o Cache the glyphs geometry into a vertex buffer object to avoid
113 resubmitting too much information to the GPU.
115 o Rework the behaviour of ClutterModel when a filter is applied.
117 o Allow submitting premultiplied texture data; this removes the need
118 for unpremultiplying data in CairoTexture.
120 o Add a simple API for submitting blending and texture combining modes
121 through a string description.
123 o Move Timelines to pure time-based objects.
125 o Lots of performance improvements.
127 o Removal of all the deprecated API.
129 o Removal of all the fixed point entry points.
131 o Lots of documentation fixes - the coverage is now 99% of the exported
132 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
134 o Generate the GObject Introspection data for both Clutter and COGL
137 o Build environment fixes.

416 Clutter 0.9.0 (30/01/2009)
417 ===============================================================================
419 * List of changes between 0.8.6 and 0.9.0
421 o ClutterText is a new actor allowing text display, text editing
422 both in multi-line and single-line modes, and text selection using
423 the pointer devices and the keyboard. ClutterText supercedes both
424 ClutterLabel and ClutterEntry.
425 o ClutterClone is a new actor that allows cloning of other actors,
426 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
427 o ClutterBindingPool is a new API that allows to easily add key bindings
429 o ClutterAnimation is a new API for implicit animations, similar to
430 the tweening API used in toolkits like jQuery, Tween and Flash. This
431 new API supercedes the ClutterEffect API.
432 o ClutterAlpha uses "animation modes" instead of raw function
433 pointers; it is still possible to pass alpha functions. The alpha
434 functions provided by Clutter have been removed from the public
435 API. It is possible to register global alpha functions and use
436 them though a logical id.
437 o The interval of the ClutterAlpha:alpha property has been changed
438 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
439 the addition of "overshooting" easing modes.
440 o COGL now supports backface culling.
441 o The COGL-based Pango renderer is public API and it is accessible
442 to developers. It is also possible to access the PangoContext used
443 by Clutter in order to create PangoLayouts to render text.
444 o The ClutterFixed API has been moved to COGL.
445 o COGL does not depend on Clutter data types anymore.
446 o The ClutterMedia interface has been overhauled: implementations
447 now must only override the interface properties. The ranges of
448 some properties have been changed to normalized values.
449 o COGL now exposes only floating point entry points, and reserves
450 the eventual conversion to fixed point only when needed. The
451 fixed point type and macros are publicly available for developers
452 concerned about floating point operations.
453 o COGL has a new Vertex Attribues API that allows submitting an
454 extensible number of vertex attributes to OpenGL in a way that
455 does not require format conversions and allows fast re-use.
456 o COGL has a new Material API that decouples paths from fills; it
457 is possible to create an arbitrary path and fill it with a COGL
458 texture. The Material API also allows setting multiple texture
459 layers and defining the blend modes and colors.
460 o ClutterTexture has the ability to use a worker thread to asynchronously
461 load an image from a file, as long as the GLib threading support has
462 been enabled prior to calling clutter_init().
463 o Clutter now supports localization of the help output, and it
464 also supports globally setting the text direction for non left to
466 o ClutterCairoTexture is a new actor that allows using Cairo
467 to draw on a ClutterTexture; since Cairo does not have an OpenGL
468 backend, the drawing is not hardware accelerated.
469 o Clutter has a unit testing suite, based on the GLib unit test
470 framework, which can be used to track regressions.
471 o A ClutterPath object has been added, and it is used by the
472 BehaviourPath. The Path object allows defining paths using a set
473 of coordinates and operations. A Path can be "painted" either using
474 COGL primitives or using Cairo primitives, allowing an easier way
475 to paint non-rectangular shaped actors.
476 o ClutterInterval is a simple object, used by ClutterAnimation, that
477 describes an interval between two values, and interpolates between
478 the initial and final values of the interval.

693 o Improve the request for the best pixel format on win32.
695 o Fix a regression when sizing the ClutterStage on backends that
696 only support fixed size stages; now setting any size will result
697 in Clutter ignoring the request, like it happened in Clutter 0.6.

714 ===============================================================================
716 * List of changes between 0.7.0 and 0.7.2
718 o ClutterTexture has a new :keep-aspect-ratio property; when it is set
719 to TRUE the texture will return a preferred width maintaining the
720 aspect ratio with the given height and a preferred height maintaining
721 the aspect ratio with the given width. This allows to set the width or
722 the height and have the texture automatically request the height or the
723 width respectively while maintaining the aspect ratio of the original
726 o Added XINPUT support on the X11 backends; this provides an initial
727 support for multiple input devices. The API is X11-specific, and
728 provides support for querying at run-time support for XINPUT, for
729 getting a list of input devices and for getting the type of each
732 o The 'fruity' backend also features multiple device support.
736 o #816 - clutter_actor_request_coords() should take a const box.

750 Clutter 0.7.0 (13/06/2008), "Booska"
751 ===============================================================================
753 * List of changes between 0.6 and 0.7.0
755 o COGL, the underlying GL abstraction layer in Clutter, has been
756 completely rewritten from the ground up. Its no longer a conceptual
757 hack but a documented, fully featured library pretty much in its
758 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
759 OpenGL ES 2.0, providing a smart uniform API over these libraries
760 with various utility features such as texture tiling abstractions,
761 paths and primitive rendering, FBO, shaders, etc.
763 o Clutter now provides an experimental backend for the Apple(tm)
764 iPhone and iPod Touch families of products.
766 o The Windows platform is now natively supported instead of
767 relying on the SDL libraries. The win32 backend is still
770 o The X11 based backends now feature support for Actors that wrap
771 external X drawables (i.e the texture-from-pixmap extension and
774 o Clutter now seamlessly supports multiple stages on the backends
775 that allow this feature.
777 o The custom Pango renderer has been completely rewritten, now using
778 the more modern and maintained PangoCairo (instead of FT2), and avoids
779 nasty subclassing hacks, supports smooth fast scaling of text, has
780 many edge case issues fixed and it still is very efficient (using
781 a texture glyph cache). It is even a little bit faster.
783 o Better texture support, timeline improvements, ClutterLabel and
784 ClutterEntry improvements, and container child properties are among
785 the new features - too many to fit in the NEWS file.
789 o #358 - "window resizing doesn't show scaled stage"

864 * List of changes between 0.5.6 and 0.6.0
866 o New documentation sections inside the API reference, describing
867 the animation framework.
869 o New API in ClutterActor for computing the actor's vertices in
870 the plane of a given ancestor and accessors to query whether an
871 actor is scaled or rotated

876 o #779 - Rounding error in ClutterBehaviourScale [Havoc Pennington]
877 o #787 - tiled textures are broken

880 Clutter 0.5.6 (11/02/2008)
881 ==========================
883 * List of changes between 0.5.4 and 0.5.6
885 o Reverted a last minute change in the depth sorting function of
888 o Added the clutter_actor_move_anchor_point() family of functions,
889 which will set the anchor point at the given coordinates while
890 adjusting the actor postion so that the relative position of the
891 actor toward its parent remains the same.
893 o Provide a fallback for finding the Clutter alpha functions inside
894 a UI definition for ClutterScript in case g_module_open() fails.
896 o Add initial Frame Buffer Objects support in ClutterTexture; using
897 FBOs, where supported by the hardware and drivers, it's possible to
898 create a ClutterTexture from any actor.
902 o #386 - Stage is white unless a timeline is present
903 o #439 - timing related pong lockup due to timeline rewind...
904 o #440 - 1 pixel line flickering
905 o #442 - Shader support
906 o #451 - Improve font rendering quality (Pango)
907 o #452 - Textures are shown with distortion on Solaris/SPARC
909 o #533 - Clutter stage is not shown under some conditions

912 o #613 - Extend point transformation API
913 o #635 - Fix buffer overflow in clutter_texture_get_pixbuf() [Gwenole
915 o #643 - Superfluous "filter-quality" setting in texture_upload_data()?

930 Clutter 0.5.4 (25/01/2008)
931 ==========================
933 * List of changes between 0.5.2 and 0.5.4
935 o A clutter-x11-<major>.<minor> pkg-config file is installed along
936 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
937 ones, for libraries and applications depending on the X11-based
938 backends (GLX and EGLX).
940 o Textures are correctly unrealized before changing and freeing the
943 o It is now possible to block the automatic call to clutter_main_quit()
944 when closing the stage window using the frame controls by connecting
945 an handler for the ::event signal on the Clutter stage and checking
946 for the CLUTTER_DELETE event type and returning TRUE. This allows
947 the usage of other main loops with GLib reactors (like Python's twisted)
948 with Clutter without triggering assertions by closing the stage window.
952 o #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]
953 o #614 - ClutterActor API inconsistencies
954 o #640 - ClutterTexture unrealized with no GL context
955 o #654 - Under heavy load clutter sometimes drops the last frame of
956 a timeline [Johan Bilien]
957 o #672 - Event handling in osx backend is broken [Tommi Komulainen]

963 o #714 - clutter_event_copy for enter/leave event generates
964 extra unref [Neil Roberts]
965 o #715 - Type errors in test-shader
966 o #720 - BehaviourScale not working in python after recent
967 API change [Josh Stewart]
969 Clutter 0.5.2 (14/01/2008)
970 ==========================
972 * List of changes between 0.5.0 and 0.5.2
974 o ClutterModelDefault has been renamed to ClutterListModel
976 o ClutterModel now has vector-based variants for append, prepend and
977 insert methods; these methods are useful for bindings
979 o Add units-based variant for clutter_actor_move_by()
983 o #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
984 o #700 - Fix for clutter_effect_rotate() [Neil Roberts]
986 Clutter 0.5.0 (02/01/2008)
987 ==========================
989 * List of changes between 0.4.2 and 0.5.0
991 o New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
992 flag set will receive events from the underlying backend; the event
993 propagation chain will be walked in two directions (from the actor to
994 the top-level container and back) with the ability to block it in
997 o ClutterShader, an abstraction over the programmable OpenGL pipeline.
999 o ClutterScore, an object for controlling timelines; using a score
1000 instance is possible to start multiple timelines at once, or start
1001 a timeline after another has emitted the ::complete signal.
1003 o ClutterScript, an object for parsing a scene from an external file or
1004 a buffer; the scene is described using JSON (JavaScript Object Notation):
1005 every object is defined using its class and properties, and container
1006 objects can have their children defined as well. It is also possible
1007 do describe top-level objects such as timelines and behaviours, and to
1008 automatically connect signal handlers to signal names.
1010 o ClutterTimelines duration can now be set in milliseconds using the
1011 :duration property; the default framerate will be used to compute the
1012 actual duration in frames. The default framerate will be set by the
1013 backend, and can be overridden by the application.
1015 o ClutterTimelines direction can now be set using the :direction
1016 property; a timeline can be set to proceed forward or backward,
1017 and the direction can also be change while the timeline is still
1020 o New, experimental OSX backend.
1022 o Build environment for MS VisualStudio 2005.
1024 o ClutterModel, a generic list-based model object that can be used to
1025 implement actors following the Model-Viewer-Controller design pattern.
1026 Clutter provides a default implementation of ClutterModel, called
1027 ClutterModelDefault and using the GSequence data structure from GLib
1028 to optimize insertion and look up.
1030 o Add the ability to grab pointer and keyboard events: if an actor
1031 is set to have a grab it'll be the only one receiving events until
1032 it releases the grab.
1034 o Add the ability for an actor to receive the key focus; an actor
1035 with key focus will always receive the key events, even if it did
1036 not acquire the keyboard grab.
1038 o It is now possible to set the GL "fog" (also known as "depth cueing")
1039 effect on the ClutterStage; if the fog is enabled, actors farther
1040 away from the view point will fade into the stage background color.
1042 o Each actor now has an "anchor point", a point defined in the actor's
1043 coordinate space that will be used as the origin when scaling and
1044 rotation transformations.
1046 o Every pixel-based API has been doubled with a corresponding
1047 ClutterUnits-based function (postfixed with a '-u'), for instance:
1049 clutter_actor_set_position() - clutter_actor_set_positionu()
1050 clutter_actor_set_size() - clutter_actor_set_sizeu()
1051 clutter_actor_set_depth() - clutter_actor_set_depthu()
1053 This allows sub-pixel precision and device independence.
1055 o The ClutterLabel actor now tries very hard to provide a sane
1056 default size, if no bounding box has been requested; this fixes
1057 the :alignment property and allows the addition of the :justify
1060 o The SDL backend can now be compiled under win32 with MingW; this
1061 backend is still marked as experimental.
1063 o The OSX backend allows the compilation of Clutter under OS X; this
1064 backend is experimental.
1066 * List of bugs fixed
1068 o #423 - All actors should emit events rather than just the stage
1069 o #424 - Interface definition files

1162 has a padding. Margins and paddings are expressed in ClutterUnits,
1163 to ease the transition to the device independent units. You can use
1164 clutter_box_set_default_padding() if you want the same padding for

1182 Clutter 0.3.1 (06/07/2007)
1183 ========================
1185 * List of changes between 0.3 and 0.3.1
1186 o EGL. There are now 2 experimental EGL backends;
1187 - 'eglx', the former EGL on X11 implementation (now renamed)
1188 - 'eglnative', a new EGL 'native' backend which supporting non
1189 X11 EGL implementations (i.e framebuffer).

1212 Clutter 0.3 (29/06/2007)
1213 ========================
1215 * List of changes between 0.2.3 and 0.3
1216 o Clutter now supports both switchable windowing system and GL backends.
1217 Window systems supported include GLX, EGL and SDL.
1219 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
1220 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
1221 yet documented - usage external to Clutter is not yet advised.
1223 Backends may provide specific command line options.
1229 The GLX backend is built by default and is currently the most
1230 developed, supported and featured windowing system backend. Only
1231 OpenGL is supported via GLX.
1235 Clutter has experimental support for using SDL. Open GL is supported as
1236 is OpenGL ES via Dogles (very experimental).
1240 Clutter has experimental support for using EGL. Only Open GL ES
1241 is supported by EGL.
1243 EGL support assumes an EGL implementation running atop X Windows.
1248 Clutter now has experimental support for Open GL ES.
1249 Current known issues;
1251 + Unrealising a ClutterTexture will not move pixel data from video
1252 into system memory but simply destroy it.
1253 + BGRA, YUV Texture data not currently supported.
1255 (Use the clutter_feature API to probe for above at runtime)
1257 Open Source ES implementations this has been tested against
1258 include `Vincent' and `dgles'. Support for commerical
1259 implementations may require modifications to the configure.ac
1262 vincent: http://ogl-es.sourceforge.net/
1263 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
1265 dgles: http://developer.hybrid.fi/dgles/index.html
1267 o New ClutterEffect class provides a simplified (and thus less flexible)
1268 API wrapping around behaviours, alphas and timelines.
1269 o New Behaviours - bspline, ellipsis, rotation.
1270 o New built in Alpha functions;
1271 CLUTTER_ALPHA_SINE_INC
1272 CLUTTER_ALPHA_SINE_DEC
1273 CLUTTER_ALPHA_SINE_HALF
1274 CLUTTER_ALPHA_SQUARE
1275 CLUTTER_ALPHA_SMOOTHSTEP_INC
1276 CLUTTER_ALPHA_SMOOTHSTEP_DEC
1277 CLUTTER_ALPHA_EXP_INC
1278 CLUTTER_ALPHA_EXP_DEC
1279 o New Actors and interfaces
1280 + ClutterLayout, for writing extended layout support in actors
1281 + ClutterContainer, for generic container actors
1282 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
1283 + ClutterEntry, text entry actor
1284 o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
1285 o All internal math now fixed point based.
1286 o Clutter now has it own internal event queue.
1287 o ClutterStage new features;
1288 + Title property for naming in window decorations.
1289 + Perspective setting - The stages perspective can now be modified.
1290 o New Clutter_actor *project API calls allow for querying of tranformed
1291 actor vertices and points.
1292 o New Clutter Feature checks.
1293 o Initial ClutterUnit implementation for device independant positioning.
1294 * List of Bugs fixed
1295 o Various issues with very poor performance and Intel drivers.
1296 o #138 Fix typo in x rotation transform.
1298 Clutter 0.2.3 (2007-04-11)
1299 ==========================

1327 Clutter 0.2 (18-01-2007)
1328 ========================
1330 * List of changes between 0.2 and 0.1
1331 o Bindings, GStreamer and GTK+ dependencies moved out of tree:
1332 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
1333 o Actors now have an initial floating reference; this means you
1334 don't have to explicitely unref them: every memory an actor
1335 allocates will be freed when the group containing the actor will
1337 o Add basic run-time detection of GL features.
1338 + Use GL_TEXTURE_RECTANGLE_ARB if available.
1339 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
1340 o Add API for behaviours. A ClutterBehaviour is an object which
1341 drives a set of actors using one or more properties depending
1342 on the value of an "alpha" function.
1343 + Provide simple behaviours: ClutterBehaviourOpacity,
1344 ClutterBehaviourPath and ClutterBehaviourScale.
1345 + Provide simple alpha functions for ramps and sine waveforms.
1346 o Add fixed point API for embedded platforms with no FPU.
1347 o Add support for command line switches to Clutter, like debug
1348 flags and abort on warnings; also allow application to hook up
1349 into the initialisation sequence to add their own command line
1351 o Add Pango GL renderer for Clutter, and use it to render text
1352 inside the ClutterLabel actor; this decrease texture memory
1354 o Redo Clutter Label widget, using the new Pango renderer.
1355 o Clutter Textures do not store local pixbuf copy (of texture).
1356 o Redo group and actor scale/sizing API and functionality.
1357 o Add memory management API for ClutterColor, and string parsing.
1359 o #199 - Little group handling fix?
1360 o #198 - Detect NPOT support on more systems
1361 o #197 - Tiled textures are broken
