Actually this release was not planned, it just happened :)
After Sony released the Playstation 3 firmware with UPnP functionality our forums got really crowded – lots of people wanted to use it with an opensource UPnP server, but none worked. What followed was a perfect example on the advantages of opensource development: knowing that we do not have a PS3, users offered their help in debugging and testing, and together we were able to quickly find a solution to the compatibility problems.
So a big THANKS goes out to all of you, in return you get a new release that now also supports streaming of MP3 and MPEG4 files to your PS3.
P.S. You need to enable PS3 support in configuratoin, see http://mediatomb.cc for instructions.
