CAS 5.1 RC4 is released:
https://github.com/apereo/cas/releases/tag/v5.1.0-RC4
This is likely the last release candidate in the 5.1.x release and the project will gear up to perform a few more rounds of testing and validation before the official GA release [1] is tagged and made available. Depending on feedback and discovery of showstopper defects, the release schedule may be adjusted.
Huge thanks to all of you who have continued to test the 5.1 release line since RC1. Your feedback and contributions are very much appreciated.
