qtmoko v38  for GTA04 is now available for download from here [1]. Version for 
Freerunner will follow as soon as it compiles. For more information about 
qtmoko please visit our homepage[2].

  * gta04 is based on 3.2 kernel now
  * gta04 uses bq27000 battery driver now
  * gta04 display brightness can be now adjusted
  * gta04 much better sound routing
  * gta04 uses state files for switching audio scenarios
  * gta04 can suspend
  * gta04 modem does not report signal quality in suspend
  * cleaned up debian packages (Gilles Filippini)
  * fixed many compile warnings (Gilles Filippini)
  * alsa state files are now part of qtmoko.deb (Gilles Filippini)
  * using /sbin/wpa_supplicant now (Gilles Filippini)
  * ship logread in qtmoko.deb (Gilles Filippini)
  * mokofaen theme (Joif)
  * fixed mokofaen build segfault (Gilles Filippini)
  * updated doc with missing packages (Tiago Bortoletto Vaz)

There are still some things that needs to be fixed, but it's quite nice 
progress since v37.

The biggest change is 3.2 kernel (vanilla NeilBrown's kernel, just packaged 
for debian [3]). The kernel needs more recent gcc to compile - with squeeze 
you will get compiler error so i am compiling in sid qemu image.

Thanks to the nice CPU idle patches and other power saving options GTA04 now 
nicely charges from USB. It can now operate even without battery. I think 
there is only one problem with charging - after the battery reaches max charge 
it starts discharging and never starts charging again. But i am not sure about 
this, i'll have to try more to confirm it...

As for audio - we now use state files like on Freerunner - i have decided to 
use them for now, because they are more simple to customize on running system. 
I might change this back to amixer later.

Sound in GSM calls is now also working - i am using simple script [1] for it. 
For debugging purposes it runs in terminal so that you can see output from it. 
You can get rid of the terminal if you copy umts-sound-route-start-internal.sh 
to umts-sound-route-start.sh in /opt/qtmoko/bin.

There is still problems with GSM calls that other site hears echo and you will 
need to set silent profile in Qtmoko's settings to have sound in incoming call.

You can expect the version for Freerunner during next week. There will be not 
many visible changes. One can be smaller image - thanks to Gilles and Tiago 
for work on the debian package.
