As of r75274, patrol tokens accepted by action=patrol and generated by list=recentchanges are no longer equal to edit tokens and are no longer the same within a session. Instead, they are now different for every recentchanges row (i.e. they depend on the rcid).
It may take a while for this change to be deployed to the Wikimedia cluster, but in the meantime changing your clients to no longer depend on the patrol token to stay the same can't hurt.
This has changed again in r78141. Patrol tokens no longer depend on rcid; instead, they are the same throughout the session (like the edit token is), but NOT equal to the edit token. Also, api.php?action=patrol now only accepts POST requests.
The changes in r75274 were never part of any release and were never deployed to Wikimedia wikis.
