This topic is closed. Latest beta: Kontalk 4.0.0-beta4 - New icon for 2017!
Another beta release just a couple of days after the first one wow! That must be huge! And as a matter of fact, it is. This is a hotfix for some of our users having trouble at startup (the app crashes…). The issue didn’t came up during tests because it doesn’t happen to everyone. To those users: sorry for the trouble, go get the upgrade now! 
Please continue your wonderful job of testing and reporting bugs since that’s what will make this new version rock-solid!
Note to F-Droid users: the F-Droid build server is currently facing a bug that causes all new application builds to be unsuccessful (including Kontalk). I’m sorry but you’ll have to wait until that is fixed
