• The changelog entry links #321 as a pull request, but #321 is an issue (the PR is #323). The current URL 404s; update it to point to the issue and link the PR separately.

• The changelog entry links to PR #321, but that PR appears not to exist (likely this is issue #321). Also the trailing "(#323)" should be a proper link to the PR that implemented the fix.

- fix(durable-functions): route sync single-arg orchestrators to core-native ([#321](https://github.com/microsoft/durabletask-js/pull/321)) (#323)

packages/azure-functions-durable/CHANGELOG.md:15

• This is the v4.0.0-beta.1 release section, but this bullet refers to durable-functions@4.0.0, which is confusing/mismatched with the version being released in this PR. Consider updating the version string in the changelog entry to match the prerelease version.

- Add `durable-functions@4.0.0` — Azure Functions Durable provider on the gRPC core (+ core host helpers, E2E CI, and release pipeline) ([#282](https://github.com/microsoft/durabletask-js/pull/282))
