New major visible feature is Discourse forum support. Discourse is a nice FOSS web forum software which has it's own API for reading messages. No TapaTalk needed for Discourse forums. Currently only reading Discourse forums is supported, but posting will be added later.
If you are starting a new forum, I can recommend using Discourse as the software.
Under the hood there have been a lot of refactoring and cleanups. Goal is to use 100% same c++ code on the desktop and mobile UI versions of the reader. There is no mobile version of 2.5.0 yet available, but that should follow soon.
This release is available for Ubuntu (Wily & Xenial) and Windows. Please give feedback if you like it and have a nice summer!
