An update to Metaxa2 that has long remained in internal testing has been deemed bug-free (as far as we can tell) and has been uploaded to the Metaxa2 web site. The update brings a slightly improved classifier, and is the first release that we declare full stable, although we have found no problems with the previously available version (release candidate 3). This also means that we take a jump directly from version 2.0, release candidate 3 to version 2.0.1 without passing a final 2.0 release. The update is available here.
