Gitea 1.25.0 → 1.26.0

• Correct swagger annotations for enums, status codes, and notification state (#37030)
• Remove GET API registration-token (#36801)
• Support Actions concurrency syntax (#32751)
• Make PUBLIC_URL_DETECTION default to "auto" (#36955)

Introduce "config edit-ini" sub command to help maintaining INI config file (#35735)

The standalone environment-to-ini tool was removed and a sub command of gitea has been introduced. If you need to re-create the configuration file with only a subset of keys, you can provide an INI template file and use the "--config-keep-keys" flag.

Correct Swagger annotations for enums, status codes, and notification state (#37030)

The generated OpenAPI description is now aligned with the actual API: enum values, HTTP status codes, and notification state are documented more accurately. If you rely on the published Swagger spec for code generation or contract tests, regenerate clients and re-check any assumptions about optional fields or response shapes.

Thank you to @myers for contributing this change.

Remove GET API registration-token (#36801)

The GET endpoint used to retrieve a registration token has been removed. Automation that still calls it needs to be updated to the supported registration flow for your deployment.

Thank you to @lunny for contributing this change.

Support Actions concurrency syntax (#32751)

Workflows can now use GitHub-style concurrency groups so that new runs cancel or queue relative to in-progress jobs. That changes runtime behavior compared with earlier releases, so review existing workflows after upgrading—especially long-running or overlapping pipelines.

Thank you to @Zettat123 for contributing this feature.

Make PUBLIC_URL_DETECTION default to auto (#36955)

New installations now default to automatic public URL detection. If you depend on a specific explicit URL configuration behind reverse proxies or alternate hostnames, confirm your [server] settings after upgrade so links, webhooks, and redirects still match your environment.

Thank you to @wxiaoguang for contributing this change.
