What

If the final line owed to the transcript at exit fails to append through the storage backend, the session store records the error and stops, rather than logging it and continuing through the other storage providers.

Details
  • The logged message text is unchanged.
Evidence

Exit line owed to the transcript was not appended through the storage backend

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