Testing assistance is always welcome. If you're able to spend time testing the software, or simply verifying that your system continues to function after upgrade, you can find the latest build of the IdP in our maven repository in this directory:
https://build.shibboleth.net/nexus/content/groups/publicmaven/releases/net/shibboleth/idp/idp-distribution/
The latest SNAPSHOT tree will generally be at the bottom of the directory listing with the most recent date and the highest version available. Within each snapshot directory, a month's worth of builds are available in dated snapshots, in both zip and tar.gz format. In all other respects apart from the filename, these builds are identical to the standard installers we release officially and can be installed in the usual fashion by unpacking and running the install script.
