# Edge Functions are now Deno 1.45 compatible

Supabase [Edge Runtime version 1.57](https://github.com/supabase/edge-runtime/releases/tag/v1.57.0) is compatible with Deno 1.45.

Supabase's hosted platform was upgraded to use this release when serving Edge Functions starting last week.

If you're using Supabase CLI for local development [latest stable release 1.192.5](https://github.com/supabase/cli/releases/tag/v1.192.5), it adds compatibility for Deno 1.45.

## How do I find which version of Edge Runtime I'm running?

### Supabase CLI (local)

When you run supabase functions serve, it should show the current version of Edge Runtime used (and its Deno compatibility)

```
> supabase functions serve

Setting up Edge Functions runtime...
Serving functions on http://127.0.0.1:54321/functions/v1/<function-name>
Using supabase-edge-runtime-1.58.2 (compatible with Deno v1.45.2)
```

### Hosted Platform

You can check the served_by field in log events to see which Edge Runtime version was used to serve your function.
