Jakub, the new lead for the project, discusses what's new in this release including modularization, Grizzly 2.0 integration, updates to functional tests and code coverage using Cobertura.
Another key improvement is the OAuth (Wikipedia) client which builds on top of the Jersey client API and offers easy integration with services such as Twitter (illustrated in the Jersey samples).
Jakub's blog post has all the links for documentation, download, mailing list and issue tracker. Note that GlassFish 3.1 ships with Jersey 1.5 and that future plans for the project include the ability to run multiple simultaneous versions of Jersey in GlassFish as well as integration and optimizations for Oracle WebLogic Server.
