Here is another Gmu release for the GP2X (Open2X), the GP2X Wiz and the Dingoo A320 (Dingux). It is the last Gmu release for this year. 😉 It comes with some new features and bugfixes.

The new features include:
* A shutdown timer: Gmu can be configured such that it shuts itself down after a number of minutes or after the last track has been played. Gmu can also execute a command to shut down the entire device, so you can use this feature as a “sleep timer”. This obviously won’t work on the GP2X-F100/F200 because of the device’s mechanical power switch.
* A log bot: Gmu is now able to keep track of the played tracks by writing them to a text file. This can be used for various purposes. It might be useful for feeding those data into the last.fm system for example.
* An increased number of playlist slots: Gmu can now handle up to 32 playlists (instead of 8).

Besides those new features there are some bugfixes, e.g. the auto-play feature has been fixed. That was previously broken in the 0.7.0 series of Gmu.
