Archos have released a new firmware update for the Archos 5 Internet Tablet, v1.6.08, and the key change is the introduction of Android 1.6 "Donut". With the new version of the OS comes the quick-search box for the MID/PMP's homescreen, improved power management, native WVGA display support and VPN functionality; Archos have also tweaked media handling, so that the Archos 5 Internet Tablet better supports H.264 SD and HD videos.
Update: Strangely, all mention of the update - including the firmware itself - has been pulled from Archos' site.
The two media libraries have now been linked in their synchronizing, which means both the Archos media library and Android media library are updated at the same time, and the whole Archos Media Center app should be more responsive. They've also fixed various bugs, including random hard-drive disconnects, and made the GPS more sensitive for heading and velocity.
Archos are recommending that owners do a full reset before installing the new firmware, which you can download here. We'd be interested to hear how users get on with the new software.
