Release candidates for Kadu 1.0 are now released weekly. With each I hope that it is the last one, but new bugs (not very critical, but still annoying) are reported. There is hope that final 1.0 will be released this month. I need to cleanup our wiki page and write release notes. That won't be long document, as only one or two major features were implemented. Most of the work was focused on fixing bugs and improving stability.
There is also progress on future release (2.0). Port to Qt5 is completed and first feature was implemented today - content of input box in chat widget is now persisted and can not be lost by accident. Kadu 2.0 will use my new injeqt library for managing dependencies between classes (I'll write about it more in couple of weekd). Its first version is very simple and will be finished in couple of months. It is very probably that Kadu 2.0 will be released in 2014.
