### Patch Changes

## 3.24.0

## 3.23.0

### Minor Changes

- 74bb4a8: Implement strict mode at a contract level. Strict mode ensures that only known responses are allowed by the type system. This applies both on the server and client side. Enable this with `strictStatusCodes: true` when defining a contract. If you would like to have the vanilla client throw an error when the response status is not known then you will need to use `throwOnUnknownStatus` when initializing the client.
- df77869: Response headers are now exposed to clients. Users of custom API fetchers should start returning headers.
- 74e41dc: Add 'metadata' property to routes

### BREAKING CHANGES FOR CUSTOM API FETCHERS

If you are using a custom API fetcher, you need to start returning response headers from your fetcher as a Web API [Headers](https://developer.mozilla.org/en-US/docs/Web/API/Headers) interface.

If you are using `fetch`, just simply return `response.headers`.

If you are using `axios`, you can return `new Headers(response.headers.toJSON())`

## 3.22.0

### Minor Changes

- d61b127: Implement tanstack query cancellation
- 1c53ac9: Add `throwOnUnknownStatus` to `initClient` configuration. When set to `true` the client will throw errors for all status codes returned by the server which are not defined in the contract.
