=== RELEASE 2.20.1 ===

Sun Sep  1 09:02:57 CEST 2019 mikulas:

	Fixed an error "ERROR: event_base_loop failed: Bad file descriptor"
	if the user quits the master instance on OpenBSD.

	OpenBSD uses an old libevent-1.4.15 and it doesn't handle calling
	event_reinit from event handler.

	libevent-2.1.11 also doesn't allow calling event_reinit from event
	handler, so it is fixed as well.
