- Support for MediaAccessEvent (spec still under development ??)
- Added support for user extensions (global class only) in JS through modules - cf gpac_js for sample code.

* RTP hinting /playback is not supported yet
- Support for SVG foreignObject - all GPAC supported content can be played in a foreign object
- Added automatic switch between 2D and 3D context for VRML/BIFS Inline node
- Basic support for DCCI queries:
* the DCCI object is exposed in scripts as 'DCCIRoot'
* the related document can be specified in GPAC configuration file in the [General] section with the 'EnvironmentFile' key
pointing to an XML file to use as the ontology context
* DCCI's propertyFilters are NOT supported yet.

- Changed 3D mesh object to be slightly more compact (colors and normal)
- Unified focus model for SVG and MPEG-4. MPEG-4 focus can only be used through tab/-tab (no north/east/.. navigation)
* The MPEG-4 focus is based on the groups (2D/3D) presenting interactive features (sensors)
* keyboard mapping for sensors is:
isOver triggered when focus moves in(isOver=TRUE) and out (isOver=FALSE)
isActive triggered when ENTER key is pressed (isActive=TRUE) and released (isActive=TRUE)
direction keys with or without SHIFT to simulate mouse move
* Layout node is considered as a sensor when scroll_rate is 0, so that the user can scroll the layout

- iTune tagging support, (patch from Andrew Voznytsa with slight modif). Tagging can be done with MP4Box -itags option. The tags are passed in a single string, separated by ':', formatted as 'tag_name=tag_value'. Supported tags names are: album, artist, comment, compilation, composer, created, disk, encoder, genre, name, tempo, track, tracknum, writer.
NOTE: to make sure you mp4 is importable on an iPod, you must:
- use .m4a extension
- specify the right brands: MP4Box -brand "M4A " -ab mp42
This process is automated in MP4Box for all file with extension .m4a
- added MPEG-1/2 raw importing (extensions: .m1v and .m2v).

program-based import for MPEG-2 TS streams (MP4Box -add file.ts#program=ProgName).
- initial IPV6 support
- MP42AVI is now deprecated. MP4Client can now be used to produce uncompressed bmp/raw/AVI, dumping the complete presentattion rather than just BIFS scenes (audio is currently not extracted). Usage:
MP4Client -bmp 1-2.5-3 file.mp4 take screenshots of file.mp4 aty T=1, 2.5 and 3 seconds
MP4Client -avi -fps 15.0 -size 176x144 file.mp4 produces an uncompressed AVI of resolution 176x144, framerate 15
MP4Client -avi 4-10 file.mp4 produces an uncompressed AVI of the scene between 4 and 10 seconds
Check MP4Client man page for more details.

- support for progressive loading support for XMT and X3D files.
- new svg_in module using gpac sax parser (supports progressive loading too)
- cf configuration.html or man gpac for more info on progressive loading control

- integrated ogg lib in gpac (<gpac/m4_ogg.h>), and added ogg/vorbis and ogg/theora importers to mp4 - THIS IS NOT STANDARD AT ALL.
The current syntax is to put needed headers in the MPEG-4 DecoderSpecificInfo, with the following syntax:
u16 sizeof_header;
char *header_data;
for each header (quite similar to what is found in qtcomponents). Vorbis ObjectTypeIndication is 0xDE, theora ObjectTypeIndication is 0xDF.
Need some more testing before filing a request to mp4ra.org.
Streaming possible as MPEG-4 streams, Vorbis RTP packetizer still to be done.
