Before time began, there was the cube. Whoops, before Firefox there was the Mozilla Suite. Once Firefox took off as the most popular Mozilla project the Suite was more or less abandoned to focus all resources on it. However several users and developers thought otherwise and took up the project under the SeaMonkey project.

Today version 2.0 of SeaMonkey has appeared sporting improvements along all the bundled applications of the internet suite hosted by Mozilla. The first big (yet maybe transparent) improvement is that it's based on Firefox 3.5.x, meaning a newer rendering engine, improved extensions and themes support. Other improvements have not been seen yet in any other stable release, such as tabbed support in MailNews (it will appear in Thunderbird 3), new default theme, and RSS/Atom feed support.

You can download this entirely new release from the SeaMonkey project site, it's certainly worth a look when you have Firefox and Thunderbird installed.
