Gitea 1.25.0 removes deprecated auth, streams archives, adds 3D previews

Gitea 1.25.0 introduces major updates across authentication, performance, and collaboration workflows. Deprecated authentication sources have been removed, requiring users to update configurations before upgrading to maintain access.

The release adds built-in 3D and CAD file previews supporting STL and OBJ formats, allowing teams to view models directly in the browser. Repository archives now stream ZIP, TAR.GZ, and bundle files by default, improving speed and reducing memory usage during large downloads. Archive downloads also support Basic Authentication for easier integration with automation tools.

Workflow improvements include a new edit file feature that automatically forks repositories for users without write access, allowing quick pull request creation. Gitea Actions now supports email notifications for successful or failed runs, and authentication updates bring better SSH commit signing and OpenID Connect synchronization for SSH keys and user profiles. Users can view the complete changelog and full list of fixes in the official Gitea 1.25.0 release notes.
