We have just released a small update to Instantbird 0.1.3. This will fix the connection issue with ICQ that appeared a little more than two weeks ago (sorry it took so long!) and improve the stability. You can download this new 0.1.3.1 release from this page or just click on the ‘Check for updates’ menu to download only a small update file.
We are going to post a status update about the progress of the development of the 0.2 version soon.
