Looks like Ubuntu's Launchpad rejected the last 0.9.12 but now i (hopefully) fixed the build and submitted 0.9.12-2 into repo.
This also should fix newly subscribed groups not syncing properly sometimes.
Windows version to be released soon. I already have built it and it is in closed testing right now. There have been a lot of new users registering and even adding new forum parsers. Big thanks for you!
