Scheduled
As previously announced, we are completing the migration away from managing endpoint behavior and image deployment details through app environment variables. These settings are now managed as dedicated Endpoint Settings and Image Deployment Settings.
Rollout schedule • June 1, 2026: Enforcement begins on Shared Stacks. • June 9, 2026: Enforcement begins on Dedicated Stacks.
What changes After enforcement begins on a stack, any deploy or configure operation that submits one of the impacted variables below with a value will be rejected with the error "Deprecated environment variable used," and the operation will not complete. This is triggered by what your deploy tooling sends on each operation, not by values already stored on your app, so an outdated CLI or a pre-v5 GitHub deploy action will fail because it resends these variables every time.
Once your tooling no longer sends these variables, your deploys and configures succeed as normal. At that point any of these values still present in your app environment are migrated to the appropriate Endpoint or Image Deployment Settings and removed from the app environment automatically, with no change to how your apps and endpoints behave.
