WORKERS AHEAD!
You are viewing the development documentation for the Apereo CAS server. The functionality presented here is not officially released yet. This is a work in progress and will be continually updated as development moves forward. You are most encouraged to test the changes presented.
8.0.0-RC3 Release Notes
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 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.
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.
Get Involved
- Start your CAS deployment today. Try out features and share feedback.
- Better yet, contribute patches.
- Suggest and apply documentation improvements.
Resources
System Requirements
The JDK baseline requirement for this CAS release is and MUST be JDK 25. All compatible distributions
such as Amazon Corretto, Zulu, Eclipse Temurin, etc should work and are implicitly supported.
New & Noteworthy
The following items are new improvements and enhancements presented in this release.
OpenRewrite Recipes
CAS continues to produce and publish OpenRewrite recipes that allow the project to upgrade installations in place from one version to the next. See this guide to learn more.
Graal VM Native Images
A CAS server installation and deployment process can be tuned to build and run as a Graal VM native image. We continue to polish native runtime hints. The collection of end-to-end browser tests based on Puppeteer have selectively switched to build and verify Graal VM native images and we plan to extend the coverage to all such scenarios in the coming releases.
Testing Strategy
The collection of end-to-end browser tests based on Puppeteer continue to grow to cover more use cases
and scenarios. At the moment, total number of jobs stands at approximately 538 distinct scenarios. The overall
test coverage of the CAS codebase is approximately 94%.
Furthermore the test scenario construction logic is given the ability to limit its run to a pre-specified time window, which is specially useful when when the test requires external resources and APIs that may not be available at all times.
Gradle 9.4
CAS is now built with Gradle 9.4 and the build process has been updated to use the latest Gradle
features and capabilities. This also prepares future CAS versions to build and run against JDK 26.
Spring Boot 4.1
CAS is now built with Spring Boot 4.1.x. This is a major platform upgrade that affects almost all aspects of the codebase
including many of the third-party core libraries used by CAS as well as some CAS functionality.
JSpecify & NullAway
CAS codebase is now annotated with JSpecify annotations to indicate nullness contracts on method parameters, return types and fields. We will gradually extend the coverage of such annotations across the entire codebase in future releases and will integrate the Gradle build tool with tools such as NullAway to prevent nullness contract violations during compile time.
