Looking at the timestamp of your post, on December 5th, you asked right before the release of JBoss Application Server 6.0.0 on the 28th. During this time, the AS6 range has advanced compared to 6.1.0. The final release cycle, while AS7 conducted a fast development cycle.
At the time of publication, you can download JBoss Application Server 7.0.2.Final , as well as 7.1.0.Beta1b, depending on how close you would like to be to the cutting edge. To understand version codes and some of the software life cycles :
- Final = polished, tested and approved version
- GA = general availability, final release, preparing for the big time
- CR = GA Candidate Release Final Test and QE
- M = release release, skating features and bug fixes in the assembly
- ER = release of technical documentation, usually an assembly for a development team.
They will all differ from organization to organization, since the profiles for which each Milestone release is presented depend on the taste of project management. As an example, consider the Meego Wiki page to explain their releases of Milestone.
