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

(Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
dgles: http://developer.hybrid.fi/dgles/index.html
o New ClutterEffect class provides a simplified (and thus less flexible)
API wrapping around behaviours, alphas and timelines.
o New Behaviours - bspline, ellipsis, rotation.
o New built in Alpha functions;
CLUTTER_ALPHA_SINE_INC
CLUTTER_ALPHA_SINE_DEC
CLUTTER_ALPHA_SINE_HALF
CLUTTER_ALPHA_SQUARE
CLUTTER_ALPHA_SMOOTHSTEP_INC
CLUTTER_ALPHA_SMOOTHSTEP_DEC
CLUTTER_ALPHA_EXP_INC
CLUTTER_ALPHA_EXP_DEC
2007-06-29 10:10:54 -04:00
o New Actors and interfaces
+ ClutterLayout, for writing extended layout support in actors
+ ClutterContainer, for generic container actors
+ ClutterBox, ClutterVBox and ClutterHBox layout actors.
+ ClutterEntry, text entry actor
o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
o All internal math now fixed point based.
o Clutter now has it own internal event queue.
o ClutterStage new features;
+ Title property for naming in window decorations.
+ Perspective setting - The stages perspective can now be modified.
o New Clutter_actor *project API calls allow for querying of tranformed
actor vertices and points.
o New Clutter Feature checks.
o Initial ClutterUnit implementation for device independant positioning.
* List of Bugs fixed
o Various issues with very poor performance and Intel drivers.
o #138 Fix typo in x rotation transform.
Clutter 0.2.3 (2007-04-11)
==========================
* List of changed between 0.2.2 and 0.2.3
o Fixes to tile based textures and again clutter_texture_get_pixbuf(). [Matthew]
o Implement Gravity for ClutterScaleBehaviour. [Matthew, Rob]
Clutter 0.2.2 (2007-03-22)
==========================
* List of changed between 0.2.1 and 0.2.2
o Addition of basic XEMBED support for clutter stage. [Matthew]
o Fixes to clutter_texture_get_pixbuf(). [Matthew]
o Export clutter_group_remove_all and add associated fixes. [Matthew]
Clutter 0.2.1 (2007-02-07)
==========================
* List of changed between 0.2.0 and 0.2.1
o Add even faster double to integer (and back) conversion
functions. [Tomas]
o Fix some errors in the fixed point sine waveform
function. [Tomas]
o Use fixed point math in the Pango renderer. [Tomas]
o Improve the GL version check. [Matthew]
o Add a square waveform function. [Emmanuele]
* List of bugs fixed
o #215 - macro CLUTTER_MARK() not disabled for non-debug builds
Clutter 0.2 (18-01-2007)
2006-12-05 01:05:37 -05:00
========================
* List of changes between 0.2 and 0.1
o Bindings, GStreamer and GTK+ dependencies moved out of tree:
now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
o Actors now have an initial floating reference; this means you
don't have to explicitely unref them: every memory an actor
allocates will be freed when the group containing the actor will
be destroyed.
o Add basic run-time detection of GL features.
+ Use GL_TEXTURE_RECTANGLE_ARB if available.
+ Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2006-12-05 01:05:37 -05:00
o Add API for behaviours. A ClutterBehaviour is an object which
drives a set of actors using one or more properties depending
on the value of an "alpha" function.
2006-12-27 13:42:31 -05:00
+ Provide simple behaviours: ClutterBehaviourOpacity,
ClutterBehaviourPath and ClutterBehaviourScale.
+ Provide simple alpha functions for ramps and sine waveforms.
2006-12-05 01:05:37 -05:00
o Add fixed point API for embedded platforms with no FPU.
o Add support for command line switches to Clutter, like debug
flags and abort on warnings; also allow application to hook up
into the initialisation sequence to add their own command line
switches.
o Add Pango GL renderer for Clutter, and use it to render text
2006-12-27 13:42:31 -05:00
inside the ClutterLabel actor; this decrease texture memory
usage.
2006-12-27 13:42:31 -05:00
o Redo Clutter Label widget, using the new Pango renderer.
o Clutter Textures do not store local pixbuf copy (of texture).
o Redo group and actor scale/sizing API and functionality.
o Add memory management API for ClutterColor, and string parsing.
2006-12-05 01:05:37 -05:00

Expect CHANGES in future versions.
o Some simple examples ( also see OPT ).
o An experimental GTK-Clutter widget.
o Fairly complete Python bindings.
o Non complete but hopefully useful API documentation.
* If you want to help out see the TODO file.
