Portable Thunderbird 1.0.6 Beta has been released. For the unfamiliar, Portable Thunderbird is a fully-functional package of Thunderbird designed for removable media, allowing you to carry Thunderbird around with you on a removable drive (USB thumbdrive, portable hard drive, iPod, etc). This new release uses Thunderbird 1.0.6 as its base and now includes support for the Mozilla Calendar extension as well as split directory structures (seperate Apps and Data) as detailed in the readme.txt.
