Tatu Saloranta has released the 3.0 version of the Woodstox XML parser. Woodstox is a StAX-compliant, open-source, Java-based XML parser. It's fast, too!
My favorite new feature is the rewritten validation sub-system, along with a new validator implementation for Relax NG.
I also like the different operating modes:
Additional operating modes: parsing mode (tree [default], forest, fragment); ability to handle undeclared entities gracefully (in non-entity-expanding mode).
More information on Woodstox can be found at:

Great work, Tatu!
