if it weren't for cssu-t to cssu-s testing path I'd suggest merging thumb back into cssu-t as i think most are using it anyway. it is still a possibility, just means eventually thumb packages would land in stable.

if your then looking at "future" maemo, an update to linaro/thumb toolchain would be worth a look. a proper fix to the xlib-xcb issue with hw keyboard from qt5 work so we only need one copy of xlib. trying to port hildon to newer gtk or update qildon, see how much patching of gtk can be avoided along the way because of the tablet style focus of gtk these days.
