CAS 6.2.0 RC2 Feature Release

This post is not official yet and may be heavily edited as CAS development makes progress. Watch for further updates.
The blog is managed and hosted on GitHub. If you wish to update the contents of this post or if you have found an inaccuracy and wish to make corrections, we recommend that you please submit a pull request to this repository.

The official CAS 6.1.0 GA was released in October 2019. Since then, the project has been moving forward with the development of the next feature release that is tagged as 6.2.0. Please review the release policy to learn more about the scope of the release. This post intends to highlight some of the improvements and enhancements packed into the second release candidate in the 6.2.0 series.

If you are looking for additional info on the previous release candidate, please see this post.

Apereo Membership

If you benefit from Apereo CAS as free and open-source software, we invite you to join the Apereo Foundation and financially support the project at a capacity that best suits your deployment. Note that all development activity is performed almost exclusively on a voluntary basis with no expectations, commitments or strings attached. Having the financial means to better sustain engineering activities will allow the developer community to allocate dedicated and committed time for long-term support, maintenance and release planning, especially when it comes to addressing critical and security issues in a timely manner. Funding will ensure support for the software you rely on and you gain an advantage and say in the way Apereo, and the CAS project at that, runs and operates. If you consider your CAS deployment to be a critical part of the identity and access management ecosystem, this is a viable option to consider.

Get Involved

Shake Well Before Use

We strongly recommend that you take advantage of the release candidates as they come out. Waiting for a GA release is only going to set you up for unpleasant surprises. A GA is simply a tag and nothing more. Note that CAS releases are strictly time-based releases; they are not scheduled or based on specific benchmarks, statistics or completion of features. To gain confidence in a particular release, it is strongly recommended that you start early by experimenting with release candidates and/or follow-up snapshots.

In order to start experimenting with release candidates, at any given time, you should be able to append -SNAPSHOT to the CAS version in order to take advantage of snapshot builds as changes are made and published.



In the of the overlay, adjust the following setting:

System Requirements
There are no changes to the minimum system/platform requirements for this release.

New & Noteworthy

CAS Overlay

The CAS overlay is updated to use Gradle 6. The most notable difference is that dependencies in the build are now recommended to use the implementation syntax instead of the compile configuration, which is set to be removed in Gradle 7. The CAS documentation is also modified to reflect this change for the appropriate CAS versions. While this is not a breaking change (yet), you should begin to use and prefer the implementation to avoid surprises in the future and reduce build warnings.

Ehcache v3

The Ehcache integration is now updated to present support for Ehcache v3. The integration with Ehcache v2 is now deprecated and scheduled to be removed at a future date.

Azure Active Directory Authentication

Following up on the previous release candidate, the Azure Active Directory integration is now moved to a standalone module that is capable of both authenticating users using Azure Active Directory and fetching attributes separately as an independent attribute repository.

Other Stuff

  • Better test coverage for components that automate Spring Webflow configuration.
  • Code cleanup and better maintenance of the codebase using an upgraded version of the error-prone compiler.

Library Upgrades

  • ErrorProne
  • Spring
  • Spring Boot


Big thanks to all who participate in the development of this release to submit patches and contribute improvements. Keep’em coming!
