What's new?

  • New features:
    • Localized in French, Polish and Russian. Support for more languages will come in the next releases.
    • Installer on Windows.
    • New default message themes and new default emoticon theme.
    • Better status handling:
      • status toolbar at the top of the buddy list allowing quick status message changes.
      • offline status to quickly disconnect all accounts and reconnect when back online. The status is changed to offline automatically when the network link goes down, and is changed back to its previous state when the link is back, reconnecting accounts automatically.
      • Better control on the idle and auto-away behaviors.
      • /away, /busy, /dnd, /back and /offline commands usable from all conversations for quick status changes.
    • Basic log viewer accessible from the buddy list or conversation tab context menus.
    • Buddy list context menu: provides a way to remove buddies, move buddies between groups and an option to show offline buddies.
    • Alias buddies: usable from the buddy list context menu, or with the F2 key.
    • Lots of minor improvements, among them:
      • Facebook Chat in the list of supported protocols by default (using the XMPP protocol).
      • Detailed buddy information in tooltips when hovering conversation tabs.
      • libpurple statically linked with its dependencies and its default protocol plugins.
      • ... (about 180 code changes since beta 1, see ChangeLog since 0.2 beta 1 for details)
  • New features already in Instantbird 0.2 beta 1:
    • New tabs. This release has a new tab system inspired from the tabs of Firefox 3.5. It is now possible to have several conversation windows. It's possible to reorder tabs with a simple drag&drop. It is possible to detach a tab to move it into a new window. When the window is too small to hold all the tabs, it's possible to scroll in the list of tabs.
    • Preferences window: Instantbird has finally got its preferences window. Even though it will look very familiar to users of Firefox or Thunderbird, it contains lots of options that are very specific to Instantbird.
    • Visual refresh: The conversations windows and the account manager have been visually simplified to improve their usability, especially when resized to small windows.
    • Auto-adaptative textbox: The input box in conversations will automatically take a size that is suitable based on the size of the window and the amount of text entered.
    • Lots of minor improvements, among them:
      • Account manager improvements. The account manager has been slightly enhanced in several ways: addition of a context menu, drag&drop reordering of accounts, better default actions when double clicking, indication of how long an account has been connected, ...
      • Notifications. Pop-up notifications (using Growl on Mac) of messages arriving when conversation windows are inactive. (Turned off by default.)
      • Custom font. It's now possible to customize the font, size and color of the text of your messages.
      • Join chats is now usable with more protocols (XMPP, ...). It used to work only with IRC.
      • Menus cleanup. Items are more likely to be where you expect them. Menus finally work correctly from any window on Mac.
      • Mobile status is displayed in the buddy list and on conversation tabs.
      • Warning when exiting Instantbird if there are new unread IMs. (Can be turned off through a pref.)
      • Improved topic notification bar. It's now easy to change the topic of an IRC channel, just double click on the current topic to edit it.
      • ... (about 190 code changes since alpha 1, see ChangeLog between 0.2 Alpha 1 and 0.2 Beta 1 for details)
  • New features already in Instantbird 0.2 alpha 1:
    • Protocol plugins can be loaded as extensions. See our blog post for more details.
    • Localizability: it is now possible to translate Instantbird.
    • 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.
      • 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.
  • Updated: Instantbird 0.2b2 is based on libpurple 2.6.6 and Mozilla
  • Improved stability: we used the crash reports that we got from the 0.2b1 release and nightly builds to fix bugs that resulted in crashes.
  • And more... read the full ChangeLog for details.
