Many new things on the authoring side in this release:

• lifting of MP4Box (nicer help screens, progress reports and options cleaning). MP4Box usage is slightly different, make sure you read this first !!
• 3GPP2 tools (importers/exporters/hinters for EVRC, QCELP and SMV codecs).
• Support for ISMA E&A (ISMACryp specification) in MP4Box including hinting, and some support in players.
• More AVC/H264 (raw importer, exporter, hinter) and AVC B-slice support through ffmpeg.
• More 3GPP/MPEG-4 text support (SUB subtitles and QT TeXML import, track extraction to SRT).
• Many fixes in MP4Box hinters (AMR, MPA bandwidth signaling) and enhancement (RTP aggregation for non-MPEG-4 payloads).
• Support for AMR and AMR-WB with 3GPP floating-point code in players (much faster).
• H263 and raw MPEG-4 video (CMP/M4V) importers.
• Experimental streaming cache in osmo4 (w32 and linux) for media recording (and I do mean experimental…)
• Many, many, many fixes here, there and everywhere…

And for the first time in a year or so, Osmo4 on PocketPC (2D only) has been stabilized and is much more usable!
