+description: Backstage Release v1.25.0
+---
+
+These are the release notes for the v1.25.0 release of [Backstage](https://backstage.io/). This is an unscheduled release that replaces what would’ve otherwise been the `v1.25.0-next.1` release, due to a problem with the patch releases for `1.24.0`. The next main line release will still be released on April 16th as scheduled, but will now instead be `1.26.0`.
+
+A huge thanks to the whole team of maintainers and contributors as well as the amazing Backstage Community for the hard work in getting this release developed and done.
+
+## Highlights
+
+### Auth service fixes
+
+A number of fixes have been made to various plugins related to the new auth system:
+
+Rate limiting has been disabled as it was a bit too aggressive and didn’t interact well with proxies.
+Fixes an issue in the TechDocs CLI related to cookie auth
+Fixes an integration issue of the new auth services in the Jenkins backend plugin
+Fixed an issue in the scaffolder were credentials weren’t forwarded correctly to the action context.
+Fixed an issue where the proxy backend blocked unauthenticated requests.
+
+### Catalog
+
+The catalog backend can now be extended with additional permissions through new `addPermissions` methods of the `CatalogBuilder` and `catalogPermissionExtensionPoint`.
+The paginated catalog table now saves the search text in the query parameters and debounces the server requests.
+
+## Security Fixes
