The Marketplace and Directory Studio Website update link 'http://directory.apache.org/studio/update' does not work with Eclipse Mars.1. When requesting plug-in update/install information using the update link, the Eclipse install/update client is not able to retrieve any plug-in update/install information with respect to the 2.0.0-M10 release.
Marketplace says: "The following solutions are not available: Apache Directory Studio 2.0.0-M10"
Direct URL install says: "There are no items available"
Update link does work with Eclipse Juno & Luna, did not test with Kepler.
