What's new?

  • New features:
    • Users can now set their buddy icon and the display name of their accounts right on the contacts list.
    • New information toolbar at the top of the conversation UI, showing the buddy icon, display name and current status of your contact. In addition, you can switch the buddy you're talking to by clicking on the protocol icon.
    • The conversation tabs styling has been updated to match Firefox 4, and users of recent Windows versions will appreciate some Aero glass effects.
    • Bubbles, the default message theme, has received new time-related features, see our blog post for details.
    • (Windows 7 only) Jumplist support to quickly change the status.
    • The contact list is sorted alphabetically (both groups and contacts appear sorted).
    • Lots of minor improvements, among them:
      • You can now quickly jump to the n-th tab using <modifier>+<n> in the conversation window, where <modifier> is ctrl on Windows/Linux and Command on Mac.
      • A help command ('/help') was added to quickly and easily see which commands are available for the current conversation.
      • ... (over 90 code changes since alpha 2, see ChangeLog since alpha 2).
  • New features already in Instantbird 0.3 alpha 2:
    • Contact merging: If you talk to the same person on multiple IM networks you can now combine the buddies from each network into a single contact. When opening a new chat the buddy that is online will be chosen automatically and the conversation window will automatically switch buddies if they switch to a different IM network.
    • Tags: Tags will be used to replace the groups in the buddy list. Tags can be hidden by clicking the "x" on the right side of the buddy list, all buddies from this tag will go into an "Other Contacts" tag automatically, which is shown at the bottom of the buddy list.
    • The buddy list can now be ...
      • closed on Mac without Instantbird quitting and reopened from the Dock.
      • minimized to tray on Windows and Linux. By default close (hitting the 'x') on the buddy list will minimize to tray, this can be changed in the preferences.
    • Lots of minor improvements, among them:
      • Unknown status is now differentiated from offline status with different icons.
      • Dark variant of the "Simple" skin.
      • Nicer animations.
      • ... (over 50 code changes since alpha 1, see ChangeLog between alpha 1 and alpha 2).
  • New features already in Instantbird 0.3 alpha 1:
    • Twitter support: When the twitter account is connected, a timeline conversation automatically opens. If the conversation is closed by the user, it's reopened automatically when new messages arrive. The user should disconnect the account from the account manager to prevent new messages from being displayed.
      There's a "track" advanced option that allows to specify keywords to track. This is a comma separated list of keywords. Comma means OR, space inside a keyword means AND.
    • Under the hood: Protocol plugins can now be implemented in JavaScript.
  • Updated: Instantbird 0.3a2 is based on libpurple 2.7.11 and Mozilla 2.0.1 which brings great new possibilities for add-on developers (restartless add-ons for example).
  • Improved stability: we used the crash reports that we got from the 0.2 and 0.3 alpha releases and nightly builds to fix bugs that resulted in crashes.
  • And more... read the full ChangeLog for details.

Known issues

  • Twitter dumps too much debug information to the error console.
