4.67.1

(fix): Fall back to git tags for auto-versioning when the magic version is not embedded in any generated source file. This fixes auto-versioning for SDKs like Swift that use git tags for versioning (via SPM) rather than a version field in source code.

4.67.0

(feat): Add agents.llms-txt and agents.llms-full-txt to docs.yml so customers can upload custom llms.txt and llms-full.txt files that override the auto-generated versions on their docs sites.

4.66.1

(fix): Fix GraphQL converter to properly handle interface types. Interfaces with implementing types (e.g., CatalogProductOption with CheckboxOption, MultipleChoiceOption, etc.) are now converted to undiscriminatedUnion shapes so that all possible concrete types are discoverable in generated docs. Interfaces with no implementations fall back to plain object types.

4.66.0

(chore): Internal infrastructure for GitHub Actions-based SDK generation automation.

4.65.3

(fix): Fix broken-link checker incorrectly flagging absolute links in versioned docs pages as broken.

4.65.2

(fix): Improve error messages for fern docs preview list command. The default error now suggests checking authentication instead of network connectivity, and the full error response is logged at debug level for easier diagnosis.
