New update is out

The bad news is that those that already have -thumb installed will have to do some manual work to upgrade :P. Me and merlin1991 made a mistake with versioning scheme, now it is fixed but requires some manual work, i.e:

make sure you have both cssu-testing and cssu-thumb repositories enabled

make sure HAM is not running prior to starting the script

download and unzip the attached file in /root and change cssu-thumb-21.2011.38-1Tmaemo5.1+thumb0.sh permissions to 755

as root:
chmod 755 /root/cssu-thumb-21.2011.38-1Tmaemo5.1+thumb0.sh

then execute it

as root:
/root/cssu-thumb-21.2011.38-1Tmaemo5.1+thumb0.sh

Ignore all of the warnings about downgrading packages and answer YES when asked

then reboot your device

EDIT:
I am too tired now for a changelog, will do it tomorrow
