Due to a bug in the frensh and spanish translation which could lead to crashes on connecting to a server I released Yaaic 0.6.1 today.
The bug is fixed in this version and in addition to that there are two new main features: In the settings you can disable showing join and part messages if they annoy you. Liato contributed a patch enabling vibration on highlights. Thanks!
For everything else see the CHANGELOG at Github. Have fun with the new release!
