I have been a huge fan of Liferea, a simple RSS Reader for Linux/Unix platform. It's simple and the best thing it suits my need. Lately, i have been using the development version, 1.5.x. It's proven to be stable enough for me, but lately, they raised the requirements quite big. For example, they now require GTK+2 at minimum 2.16, SQLite 3.6.10 and above, Webkit 1.1.1 and above, and libsoup 2.26 and above.
Due to this constraints, i haven't upgraded my Liferea installation and i'm still at 1.5.14 even though the latest development version is now 1.5.15 and they are working on 1.5.16.
The good news is that Liferea 1.6 will come out shortly, which means the end of development cycle for 1.5.x version is coming to an end. Let's just hope they will have a good release on 1.6.x replacing the stable version 1.4.x.
