The CD Foundation currently has 7 open source projects: CDEvents, Jenkins, Jenkins X, Ortelius, Screwdriver, Spinnaker, and Tekton.
Our projects solve some of the biggest issues in the Continuous Delivery and Continuous Integration space. We always want to expand our project communities with additional contributors, end users, and passionate technologists. Please check out each project to see what you can do to get involved!

CDEvents
During the third quarter of 2025, the CDEvents project worked on two fronts:

- Jenkins 2.517 (July 1) – Added window listener computeOverflow for breadcrumbs computation and asynchronous periodic work executions

- Jenkins 2.516.2 (August 20) – Restored breadcrumb navigation and fixed anchor links in documentation
- Jenkins 2.516.3 (September 17) – Critical security updates and memory leak fixes
Jenkins is also participating in Google Summer of Code, Hacktoberfest and more.
Ortelius
- Easy onboarding into Ortelius, starting with Jenkins
- Easier CI/CD installs
- High and Critical CVE notifications
- AI Model Context Protocol (MCP)
Screwdriver
Notable Updates:
- Streamlined metadata update process by moving the logic to API layer.
- Upgraded sonar-scanner
- Added configurable webhook payload size
- UI Updates
Upcoming enhancements:
Spinnaker
The Spinnaker platform is stable at this point. The primary work currently being done and planned is around performance improvements and updating dependencies to the later releases like Spring Boot 3 and AWS SDK v2.
- AWS SDK2 is slowly going into various services.
- Spring boot 3 has a PR in draft, but has significant changes through-out the project to be applied.
Features and release
The biggest recent set of changes are fixes around retrofit1 to retrofit2 upgrades that had broken numerous releases. As such, 2025.2.2 is the most stable and recommended release at this time. It’d be best to avoid the 1.38 and 1.37 based releases in favor of this version. Supported releases and notes.
