• [nitpick] Since the interface signature has already been updated in this release, consider updating the wording from 'will change' to reflect that the signature has changed, or remove this note to avoid confusion.

	 * Signature will change from `(reason: IAnyDriverError) => void` to `(reason: IAnyDriverError | undefined) => void`.

.changeset/fuzzy-turkeys-help.md:16

• [nitpick] This sentence may be confusing since accepting undefined is already introduced in this release; consider rephrasing or removing it.

In a future release, the `reason` parameter will also accept `undefined`.

Seems like there was an announcement regarding this in the last release? Should it be removed from the release notes? https://github.com/microsoft/FluidFramework/releases/tag/client_v2.43.0#user-content-the-reason-parameter-on-the-disconnect-event-is-now-optional-to-allow-for-clean-non-error-disconnections-24840
