It has a zip file containing a replacement WPIJavaCV.jar file (built from source on 2012-Feb-05) that seems to have addressed the memory leak issue that we ran across while using the SmartDashboard for image processing.
NOTE: This isn't a official release of the JAR file, I just downloaded the source directly from the WPI subversion server and built it. So, if you are not in a hurry, it might be wise to wait for a official release.
