The GeoServer team is making great progress on our 2025 roadmap plans, with CITE Certification Achieved, and GeoServer 3 underway, the project is going well.

Thanks to GeoServer 2025 sponsors:

CITE Certification

We are really happy to the see the CITE Certified banner restored to the main GeoServer website for calendar year 2025. Andrea continues to work on certifying the new OGCAPI services:

  • OGCAPI - Tiles: Passing tests on Team Engine 2.0 Engine

  • OGCAPI - Process: Making progress on certification

A reminder that if CITE Certification is valuable to you GeoServer will need to pay OGC each year - which requires sponsorship. We are certified for calendar year 2025 thanks to the prior sponsorship. We find that many organizations assume GeoServer is certified, this is not be the case without your financial support.

Thanks to Gaia3D and OSGeo:UK for sponsoring 2025 CITE Certification.

Security

We continue to be in need of resources, both developer resources and funding, to address the expectations placed on open source projects. If you are in a position to support this activity, please contact us at geoserver-security@lists.osgeo.org .

GeoServer 3

The big news is the completion of Milestone 1 : Preparation with the release of GeoServer 2.28.0, allowing the Milestone 2 : Migration activities to proceed as scheduled.

For more information on GeoServer 3 development, review the project plan and GeoServer 3 Crowdfunding FAQ.

GeoServer 3 Milestone 1 Completed

The release of GeoServer 2.28.0 represents the end of Milestone 1: Preparation:

  • Upgrade from Java Advanced Imaging 1.1.3 to Eclipse ImageN 0.9.0.

  • Java 17 LTS minimum, ending support for Java 11.

  • Lots of build improvements, with the highlight being a bill-of-materials “geotools” pom.xml file to manage versions across GeoTools, GeoWebCache, and GeoServer.

  • A new community module, gs-sec-oidc-plugin, replacing gs-oauth2 plugins.

GeoServer 3 Milestone 2 Underway
