+* Fix occasional deadlock leading to memory leak, the deadlock was introduced in Centrifugo v5.3.2, see [#856](https://github.com/centrifugal/centrifugo/issues/856). While fixing an issue we've also found a scenario in which the number of clients and subscribers could be incorrect – subscribers could go away, but the subscriber counter is not decremented. Fixed this alongside the deadlock, both issues do not reproduce with our test load anymore.
 * Fix non-working `allow_presence_for_subscriber` option to enable join/leave events when requested by client, see [#849](https://github.com/centrifugal/centrifugo/issues/849)
