3.37.3

(fix): no-op: initiate bulk cli update

3.37.2

(fix): Fix fern generate --preview failing with permission errors when the .preview folder already exists. The CLI now properly handles read-only files (like .git/objects) by making them writable before deletion.

3.37.1

(fix): Push full channel message payload schemas through when creating type references; helps support ‘bytes’ for websocket methods.


3.37.0

(chore): Add Excel file support (.xlsx) to the allowed file types for documentation uploads. This enables users to host Excel files using the <Download /> component.


3.36.0

(feat): The fern init command now automatically creates a .gitignore file inside the fern/ folder with entries to ignore .preview and .definition directories.

3.35.2

(fix): Default dynamic SDK snippets on if the experimental configuration is already present.


3.35.1

(fix): Respect the path-parameter-order setting from generators.yml when importing OpenAPI specs, which is different from the path-parameter-order on the api.settings level. By setting both levels to spec-order, you can preserve the old behavior of using the order defined in the OpenAPI spec.

(fix): Fix local generation to convert self-hosted GitHub URI (owner/repo) to full URL format, matching Fiddle’s remote generation behavior.

3.33.0

(fix): Fix handling of OpenAPI schemas that use discriminator.mapping without explicit oneOf/anyOf. These schemas are now correctly converted as discriminated unions instead of plain objects. This pattern is used by APIs like Dropbox Sign where a base schema defines a discriminator with mapping to variant schemas.


3.35.0

(feat): Add x-fern-parameter-name extension support for AsyncAPI parameters. This allows customizing parameter names in generated SDKs for AsyncAPI specs, similar to existing OpenAPI support.

3.34.0

(feat): Updates the SDK snippet generation to use dynamic snippets by default. To disable, set experimental.dynamicSnippets to false in your docs.yml file.


3.32.0

(feat): Add extends field to dynamic IR ObjectType to expose inheritance information for generators that need to handle inheritance patterns differently (e.g., Rust uses flattened wrapper fields).

3.31.2

(fix): Fix broken link checker incorrectly flagging internal paths with external redirects as broken. Links to paths that redirect to external URLs (e.g., /ui → https://auth-platform.example.com) are now correctly validated.


3.31.1

(fix): Fix double JSON.stringify in dynamic IR upload, reducing memory usage and ensuring correct Content-Length header calculation with Buffer.byteLength.

3.31.0

(fix): Add a --dynamic-ir-only flag to SDK generation to enable access to dynamic snippets from SDKs without regenerating the entire SDK.

3.30.6

(fix): Only upload dynamic IR for SDK generation after confirmed success and when not in preview mode.


3.30.5

(fix): Support x-fern-base-path extension in the OpenAPI v3 parser.

3.30.4

(chore): Add ACH to special tokens list to preserve capitalization in docs sidebar navigation.


3.30.3

(chore): Adds a product-switcher.toggle theme option to the docs configuration.

3.30.2

(fix): Export all defined auth schemes when using endpoint-security auth in generators.yml.

3.30.1

(fix): Update generators.yml schema SDK update to include api.auth.endpoint-security support.
