 * ``VersionedFileStore`` no longer uses the transaction parameter given
   to most methods; amongst other things this means that the
   get_weave_or_empty method no longer guarantees errors on a missing weave
   in a readonly transaction, and no longer caches versioned file instances
   which reduces memory pressure (but requires more careful management by
   callers to preserve performance.  (Robert Collins)
