##### Breaking Changes
- Team members with the **Member** role became read-only. They could still view team resources and configuration, but could no longer create, update, delete, deploy, start, stop, or otherwise modify resources. Review team roles and promote users who still require write access ([v4.2.0](https://github.com/coollabsio/coolify/releases/tag/v4.2.0)).
- State-changing API endpoints began requiring **POST**; legacy `GET` requests now return `405 Method Not Allowed`. This affected `/enable`, `/disable`, `/deploy`, server validation, application/database/service lifecycle actions, and service-application lifecycle actions ([v4.2.0](https://github.com/coollabsio/coolify/releases/tag/v4.2.0)).
- Changed proxy router names for Compose services containing dots or hyphens to use a stable suffix; custom references to previous router names must be updated ([#11040](https://github.com/coollabsio/coolify/pull/11040)).
- Removed confirmation dialogs for deploy, redeploy, and force-deploy actions; these actions began immediately when selected ([#11023](https://github.com/coollabsio/coolify/pull/11023)).
