I have released Adept version 2.1.1 few days back, it is now in debian unstable. The preferred way to download is through normal apt-get in debian. Please ignore the kde-apps.org download link, it leads to an older, buggier version (2.1) which you won’t be able to compile anyway unless you get the build dependencies right.
On other front, work on 2.2 release is ongoing, it is getting back into an usable shape. Most of the work so far has been under the hood, although the usability/gui changes should be coming as well. I haven’t yet decided which features to have in 2.2 and which to postpone. Probably, the modebar and new workflow will have to wait, i will be glad if i get the filter layout changes finished in some reasonable timeframe for 2.2.
In other news, adept 2.2 branch is getting more and more useful on rpm platforms, thanks Bero for pushing that.
