## 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.
