Comet version 2.0.1 has been released (this Wednesday). It can be downloaded here.

From the release notes:

Version 2.0.1 is a revision on 2.0 that includes several enhancements and bug fixes. The Comet Documentation is now also shipping as a separate installer for each OS so that it can be updated on a more frequent basis, independent of the release of the Comet System. The installers for the Comet System include the latest version of the documentation.
