Instantbird

Release Notes: Stability fixes, dramatic reduction of resource consumption in some cases, and cool features making Twitter and IRC much more usable: a context menu to retweet, reply to a tweet (or simply double click on the tweet to start a reply), or (un)follow the author of the tweet; tab completion of usernames (Twitter) or nicknames (IRC); and conversations can now be put on hold: close tabs without leaving the conversation, and reopen it from the Contacts window. This is exceptionally useful for IRC users idling in many channels.

Release Notes: After years of hard work, Instantbird has finally reached the 1.0 version and is ready to be put in everybody's hands. This version is available for Windows, Mac OS X, and Linux and is released in 11 locales. Compared to the previous major version, this release brings in a dramatically improved handling of contacts, better system integration, Twitter support, and hundreds of improvements throughout the application.

Release Notes: This beta brings significant appearance changes with user icons, an updated tab style, the improved default message theme, Aero glass effects on Windows, and more new features. This release, the first localized preview, is already available in 10 locales (Czech, German, English, Spanish, French, Dutch, Polish, Russian, Slovak, and Ukrainian).

Release Notes: If you talk to the same person on multiple IM networks, you can now combine the buddies from each network into a single contact. A tag can now be hidden by clicking the "x" on the right side of the buddy list; the contacts from this tag will be shown in an "Other Contacts" tag automatically, at the bottom of the list. Windows/Linux users will appreciate the minimize to system tray feature, and Mac users will like being able to close the Contacts window without quitting the application.

Release Notes: This release contains very significant changes, including the ability to create JavaScript protocol plugins and the upgrade to the Mozilla 2.0 platform. Most of the changes are not yet visible in the user interface, so current users of the 0.2 version are not advised to update. However, it includes basic support for Twitter and is already quite stable, so it will please early adopters and testers who don't go as far as to use nightly builds. Add-on developers will also be interested, especially because of the new ability to create restartless add-ons.
