Yep so far no notes about each release, which is quite frustrating.
I suppose you could diff between versions...
I unpacked the update.img from each 2.4, 3.3.2, 3.3.3 using ImgRepackerRK
, and then compared the dumps using WinMerge
You can read about the format of the update.img here: http://wiki.t-firefly.com/index.php/Firefly-RK3288/Customize_android_firmware/en
Here's an overview of the differences from 2.4 to 3.3.2:
from 3.3.2 to 3.3.3:
and lastly, 2.4 to 3.3.3:
As you can see:
- The parameter.txt doesn't change
- The RKMiniLoader version is bumped from 2.19 to 2.25
- There are differences to the partitions (e.g. system.img)
We can extract the system.img using ext2explore.exe
to diff the system partition, and take a look at the preinstalled apk's:
The difference in preinstalled apk's is probably due to the 3.3.2 release not being English, and so not including many of the English services (Youtube, Twitter, etc.) but including many Chinese services (QQ).
From 2.4 to 3.3.3 we have had the addition of "xiyuegame" which is the "Playable" apk I've mentioned previously
, and the removal of Gmail and Maps (as they can be installed from the Play store).
Other than that, unless GPD give us an exact changelog (unlikely) we're not going to know what has changed.
