Fedora Core team has its own release schedule just like this Releases/17/Schedule
And all the SpringSource's projects appear here , where I can choice a specific project and later do click in versions option to see its release schedule.
For example the follow is for Spring Core
Where I can find the Release Schedule for each vFabric technology available? (Hyperic, tc Server, RabbitMQ, GemFire etc). I did the same question in VMware community support (through emails), and they told me to make the same question in this forum.
BTW these technologies are referred in http://www.springsource.com/
Thanks in advanced
