If you've been using the VSS Plugin for cfeclipse and you're looking to upgrade to eclipse 3.3, you'll find that some of the functions don't work correctly. In particular, for me, I lost the ability to inspect the file histories in vss.

Kudos to Jeff Barcalow for patching the jar file and Peter Szanto for packaging up the distribution and publishing it.
Use at your own risk, though.
