While previous betas in the 2.0.0 series have been extremely stable, and we recommended their use, this release is actually of beta quality. This is our first release to reflect the name change from Gaim to Pidgin, and so there are a lot of fairly significant changes here, which we’d like to see have broader testing before declaring it ready for release. If you would like to help us out, grab a copy from Sourceforge.net.
Not much has changed since GAIM 2.0 Beta 6, but there are a few new graphics and icons, including the main application icon seen here. Worth a download, but it’s recommended that you back up your GAIM directory prior to upgrading.
