Radical V0.5 was released, it can be downloaded from:

http://idanso.dyndns.org/radical/

Radical is a ruby based web appliction server, it provides templates, i8n, 
logging, caching, database poll and authentication, and extendable by writing 
additional handlers.

It's been some time since the latest release, but in the last two weeks I made 
quite lot of work on the codebase.

The I8N files syntax was changed to make it easier to edit. instead of:

"#{src}" "#{trg}"


A simpler syntax is being used:

**********
#{src}
++++++++++
#{trg}

The template API is somethat more intuative and easy to use.

The LogManager API was extended to include methods such as log() and error()

Added database pooling(depended upon Ruby-DBI), Session manager and an API for 
authentication

Added support to make Radical run in the back of apache via mod_ruby and DRb

Most of the configuration is done via XML(depends upon REXML)

Many bug fixes and better exception handling, namespace changes and lots of 
other minor stuff which made the whole thing cleaner:-)
