## 3.27.0

**`(feat):`** Add `ENDPOINT_SECURITY` value to `AuthSchemesRequirement` enum in the IR.
This allows users to specify that authentication requirements are defined per-endpoint rather than globally.
Users can now use `endpoint-security: {}` in their Fern API definition's `auth` field to indicate that security is configured on individual endpoints via the `security` field.

## 3.26.3

**`(chore):`** Add `x-fern-sdk-method-name` support for AsyncAPI operations.

## 3.26.2

**`(chore):`** Support custom environment variables and shell command operators in native local generation for seed testing.

## 3.26.1

**`(fix):`** Fix `fern docs dev` to start the backend server before Next.js. Previously, Next.js would start immediately while the backend was still initializing, causing requests to fail if users opened the browser too quickly. The backend now fully initializes before Next.js starts accepting requests.
