The final version has been released. Topic locked.
I've just posted a test release of Pidgin Portable 2.1.0. Pidgin, formerly known as Gaim, is a multi-protocol instant messaging client that works with AOL, MSN, Yahoo, Google, ICQ, Jabber and other networks all within an easy to use interface. This new test release now fully supports using a CommonFiles\GTK folder (as GIMP does). It also has built-in support for Pidgin preferences paths so your buddy icons and other settings will work as you move PCs.
The installer will not affect an existing Gaim Portable installation, but if you install Pidgin Portable to your PortableApps directory alongside your existing GaimPortable directory, it will automatically copy your existing Gaim Portable settings to Pidgin Portable. The package is an 11MB download and requires 13.6 to 43.9MB to install depending on whether you select to install the translations or not.
Note: May take a few minutes to hit the download servers
