We have completed the upgrade of our Nexus instance (https://repository.jboss.org/nexus/). The upgrade went smoothly, however this upgrade requires a full rebuild of the Nexus index files. The index generation seems to be resource intensive and is causing our Nexus instance to respond slowly to new requests. This should be resolved sometime today when the index generation is complete.
There are some notable improvements in the new version.
The search interface is improved and you should no longer see messages like "too many results".
The staging repositories all all grouped together now, so you can just click on the "Staging Repositories" link to find your repo during a release.
Better handling of remote proxy repository failures.
Today we will be updating the wiki documentation which describes Nexus usage to relect changes in the new version.
