We are excited to announce that Seafile 13.0 is now available for testing! This new version brings a host of powerful features designed to enhance your file management and collaboration experience.
The final production ready version will be available in the end of this year.
Key updates:

Multiple view types for file display

Seafile AI
SeaDoc is now version 2.0 and includes AI integrations
Seafile 13.0 beta version is safe to use in production in general if you don’t use the new metadata feature. Other features are small changes from version 12.0.
