People often ask what the difference is between the free GlassFish and the commercially-supported version. The answer really is "not much" in terms of the core server itself (pretty much just branding changes). The commercial version, though, has some nice value-add features, such as the Performance Tuner , amongst others.
I'm really, really pleased with how GlassFish 3.1 has turned out. We still (and will always) have more work to do, but this is a solid release that finally fills in some enterprise holes that v3 didn't have time to fill. Download it, install it, kick the tires a bit, and tell us what you what you think . In the meantime, we're going to go ahead and get started on 3.2.
