(from Paolo Perego)
I'd like to announce that the first public version (marked as 0.30.0) of the OWASP ESAPI for Ruby gem has been released.
We choose to release early, release often so we started pushing out to the real world even if we started no more than a month ago. We started porting validators, codecs and filters but the road towards 1.0 is far from being close.
Since a lot of work has to be done, we need a lot of talented people, so please go to http://www.owasp.org/index.php/Projects/Owasp_Esapi_Ruby and subscribe to the project mailing list. At the owasp.org webpage you can find link to source repository, with all the information you need to contribute to the project.
