Cross platform IM client InstantBird goes 1.0
InstantBird is a cross platform, open source, instant messaging client which has just reached version 1.0. The GPLv2 licensed InstantBird runs on Windows, Linux and Mac OS X and is based upon libpurple and code from various Mozilla projects. It has been in development since 2007, when it began life as an "XUL UI for Pidgin".
Since then the developers have been releasing working versions with "small" 0.x.x version numbers but recently reconsidered their position. Given they were due to release InstantBird 0.3 "with more changes than any previous release" and were unlikely to release a future version with as many changes, they decided to make 0.3 their version 1.0.
