There is not only a lot of activity around the core of Blosxom but also at the plugins front:

The Blosxom developers are currently preparing the first release candidate for the Blosxom Plugins Collection. The collection will probably be available in different sets:

• blosxom-plugins-small — for the purists, with 5-10 almost-core plugins
• blosxom-plugins-medium — for the masses, with the 20 or 30 most useful plugins
• blosxom-plugins-large — for the wasteful, with the entire set

Have a look at the CVS repository to get an idea, what's coming up soon.
