The actual XPages-related code in this release is the same as in Beta 2. What's new is the addition of the servlet I wrote a little while back, cleaned up slightly.

The servlet is actually entirely distinct from the XPages portion - it's not implemented as an OSGi servlet and doesn't share any code or runtime attributes. Nonetheless, it's rather lightweight and still potentially useful. It allows for executing .rb scripts stored as File Resources in an NSF via GET and POST requests in much the same way as a PHP file or Perl script.
