Community Edition Updates
- When the server is configured to use only HTTPS, a Strict-Transport-Security header will be set to prevent future attempts to access the server over HTTP. Also available in 24.11.4.
- 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)
- Administrators can register a list of acceptable file extensions for uploads; others will be denied. If no list is provided, any extension is allowed.
- Encoding of WebDav URLs has been made more consistent; users who have been relying on the previous behavior may need to make changes. (docs | details)
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. (new installation docs)
- LabKey Cloud subscribers are upgraded automatically.
- Users with on-premise installations who have already upgraded to use embedded Tomcat should follow these upgrade instructions. (upgrade on linux | upgrade on windows)
- Users with on-premise installations that have not already made the additional changes required to use embedded Tomcat will need to follow the migration process in the documentation archives. (migration docs)
