Community Edition Updates
- Study participants can be deleted from all datasets at once. (docs)
- Set a timeout for read-only HTTP requests, after which long running processes will be killed. (docs)
- Encoding of WebDav URLs has been made more consistent; users who have been relying on the previous behavior may need to make changes.
Distribution Changes and Upgrade Notes
- LabKey Server embeds a copy of Tomcat 10. It no longer uses or depends on a separately installed copy of Tomcat.
- LabKey Cloud subscribers are upgraded automatically.
- For users with on-premise installations, the process for upgrading from previous versions using a standalone Tomcat 9 has changed significantly. Administrators should be prepared to make additional changes during the first upgrade to use embedded Tomcat. (docs)
- For users with on-premise installations who already upgraded to use embedded Tomcat will follow a much simpler process upgrade to 25.3. (linux | windows)
- The process for installing a new LabKey Server has also changed significantly, making it simpler than in past releases. (docs)
Deprecated Features
