What's New in This Release: [ read full changelog ]
Supported devices:
· The Sansa c200v2 series is now stable
· Unfortunately some serious issues forced us to downgrade the Ipod Nano 2g to unstable, so it isn't included in the 3.11 release. We hope to add it back in a future update.
Core:
· Allow customisation of the main menu (see Advanced Topics section of the manual)
· Sansa Clip (+,Zip) players can now return to WPS using the Home key FS#12288
· Initial RDS support for Si4701/Si4703 tuner (clip zip) FS#12370
· USB enabled on Sansa AMSv2
· iPod hardware clicker FS#5111
· User shortcuts in the main menu FS#12251
· Implemented GUI boost (timed out CPU boost during scroll activity) for a more responsive GUI. For now on scroll wheel targets only. FS#8668
· List icons and theme images can now have alpha information embedded, i.e. be transparent, using 32bit ARGB bitmaps. This removes the need for the magic magenta (#FF00FF) transparency, but this is still supported.
· List icons can now be arbitrarily sized, removing the old 24x24 limitation, and saving RAM for the default 12x12 icons.
Codecs:
· Support multichannel flacs including downmixing to stereo FS#12443, FS#12371
Plugins:
· The rocklife plugin has been moved from games to demos. After upgrading you can safely delete .rockbox/rocks/games/rocklife.rock
