Summary

This release introduces local support for `cf.image` transformations during development, mirroring production behavior, and improves error reporting for missing resource bindings in Miniflare.

Migration Steps

  1. If you rely on `cf.image` transformations in `wrangler dev`, ensure that the `sharp` package is installed locally for transformations to function correctly.

✨ New Features

  • Support for `cf.image` (transform via Workers) image transformations in local development using Sharp.

🐛 Bug Fixes

  • Miniflare now reports the expected binding type in error messages when methods like `getKVNamespace()` or `getR2Bucket()` are called with a missing binding name.
