Kindle software update version 2.0.3 is being rolled out over the WhisperNet. I decided not to wait for the automated installation to fail because I have font hack and Savory installed and did a manual update. Uninstallers for both hacks worked just fine and official update installed without any problems. I used Igor’s script to take a peek inside the update packages and copied some files from Kindle before I installed the update. I then sucesfully applied the official patch, made another copy of the files that were updated but didn’t find any exciting changes.
All-in-all, it looks like a collection of bugfixes. It’s possible that TTS change is there.
First thing after the official patch – I’ve reinstalled the Unicode Font Hack and it installed just fine.
