We have updated the artifacts available for testing for the Zenoss 2.5 "King Crab" beta. There are now installers available for all platforms and the VMware image is now available for testing. Please refer to the original beta announcement for testing instructions, the downloads are available at http://community.zenoss.org/community/beta. Testing upgrades is still not supported, this should be addressed in the next beta release.
