# All regions now run Deno 2.1 compatible release

We've fully rolled out the Deno 2.1 compatible release on all regions serving Edge Functions. You don't need to change your existing Edge Function invocations; the nearest region will automatically serve them using the Deno 2.1 release.

Along with the Deno 2.1 release, the features we announced during the launch week also became available in all regions: https://supabase.com/blog/persistent-storage-for-faster-edge-functions

### Fallback to Deno 1.45

In case your Functions start experiencing any compatibility issues with Deno 2.1, you can temporarily fallback to the 1.45 release in two ways:

* Add query parameter `forceDenoVersion=1` to your function requests

 ```
https://project-ref.supabase.co/functions/v1/hello-world?forceDenoVersion=1
````

* Add `x-deno-version: 1` header in requests

```
curl --request POST \
  --url https://project-ref.supabase.co/functions/v1/hello-world \
  --header 'content-type: application/json' \
  --header 'x-deno-version: 1' \
  --data '{
  "name": "test"
}
```
