What's new?

  • Improved stability: we fixed the outstanding bugs that resulted in crashed.
  • Proper handling of non-ASCII characters. Instantbird now uses UTF-8 for all strings.
  • Usability improvements. We fixed bugs that didn't require much of our time and will significantly improve the user experience. For examples: aliases in the buddy list, linkification in the chat window... We also removed some common annoyances in the UI.
  • IRC Chats. In order to build a community, we thought it was critical to provide some way for users and testers to talk in a public place and not only send us private messages. There is now in the "File" menu a "Join Chat" item which will allow users and future contributors to join us in
