What's new?

  • New features:
    • Protocol plugins can be loaded as extensions. See our blog post for more details.
    • Localizability: it is now possible to translate Instantbird. The experimental french language pack is an example.
    • Conversation window improvements:
      • Message filtering. For security, undesired HTML markup is filtered out of IMs before displaying them.
      • Smileys. Emoticons are now replaced by images, and there is a theme system for these sets of images.
      • Message styles. Styles similar to the ones of Adium can be used with Instantbird.
      • Context menu with search engines integration.
      • Improved copying of messages. When selecting several messages in a conversation and copying them to the clipboard, they will be formatted in a way suitable for pasting it as a citation, for example in an email.
  • Updated: Instantbird 0.2a1 is based on libpurple 2.5.8 (which fixes Yahoo! connection issues) and Mozilla 1.9.a1pre.
  • Improved stability: we used the crash reports that we got from the 0.1.2 and 0.1.3.* releases and nightly builds to fix bugs that resulted in crashes.
  • Under the hood:
    • The preference system of libpurple has been plugged into the Mozilla preference system. Preferences of libpurple are now accessible from about:config.
    • Gettext has been replaced.
  • And more... read the full ChangeLog for details.

Known issues

  • People using a Google Talk account from Google Apps won't be able to connect it with this version of Instantbird.
  • On Windows, copying several messages from a conversation and pasting will result in broken line breaks in some applications.
