What

The messaging tool's recipient field gained a length bound alongside the existing single-line check, so an overlong recipient fails validation immediately rather than later during resolution.

Details
  • The rejection message says the value "must be a single-line recipient name or address".
Evidence

must be a single-line recipient name or address

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
