Note that a bug is also filed for a version bump - so please make sure this happens in the 2.0.6 ebuild. Also, Orion is a pure Java package, so could be marked stable straight off. There's nothing in there that's going to affect the stability of the system, and there's no bugs in there that Gentoo are going to fix.
we're testing it now.
Afaict, the latest version is 2.0.5, not 2.0.6. At least 2.0.6 is not available on www.orionserver.com today.
