* `passlib`_ is now used for all password hashing instead of flufl.password.

   The default hash is `sha512_crypt`.  (LP: #1015758)
 * Events renamed and moved:
   * `mailman.chains.accept.AcceptNotification`
   * `mailman.chains.base.ChainNotification`
   * `mailman.chains.discard.DiscardNotification`
   * `mailman.chains.hold.HoldNotification`
   * `mailman.chains.owner.OwnerNotification`
   * `mailman.chains.reject.RejectNotification`
   changed to (respectively):
   * `mailman.interfaces.chains.AcceptEvent`
   * `mailman.interfaces.chains.ChainEvent`
   * `mailman.interfaces.chains.DiscardEvent`
   * `mailman.interfaces.chains.HoldEvent`
   * `mailman.interfaces.chains.AcceptOwnerEvent`
   * `mailman.interfaces.chains.RejectEvent`
 * A `ConfigurationUpdatedEvent` is triggered when the system-wide global
   configuration stack is pushed or popped.
 * With the switch to `passlib`_, `[passwords]password_scheme` has been
   removed.  Instead use `[passwords]path` to specify where to find the
   `passlib.cfg` file.  See the comments in `schema.cfg` for details.
