Hi, I've added the "JCR 1.0.1" and "JCR 2.0" components in the Jackrabbit issue tracker to better track changes related to the JSR 170 maintenance release and the JSR 283 specification.
The spec component tags should always be associated with a structural tag that identifies the functional area that the issue is about. For example a request to impelement new versioning functionality specified in JSR 283 should be tagged with both "versioning" and "JCR 2.0" components. BR, Jukka Zitting
