4.65.1

(fix): Fixed a performance issue in fern check where valid-markdown-links repeatedly reprocessed duplicate API descriptions and pathnames in API sections, significantly improving runtime on large docs sites.

4.64.1

(chore): Tag Sentry errors with fern_run_id and github_run_id for cross-run correlation. The CLI now generates a FERN_RUN_ID at startup if one is not already set in the environment (e.g. by the fern-api/actions/setup-cli GitHub Action), threading a single correlation ID through all CLI invocations in a workflow run.
