      * Update SNACS annotations to the v2.6 standard (automatically rename p.Causer -> p.Force and p.RateUnit -> p.SetIteration).
      * Update UD to v2.10. This affects many UPOS tags and lemmas, especially for proper names. The UD update also introduces lines encoding multiword tokens (not to be confused with multiword *expressions*) for clitics.
   - STREUSLE 4.4: 2020-11-04.
