Description: 

node_access_write_grants is now named _node_access_write_grants to discourage its use. Any module writing its grants with this function will always get them written. However, when rebuilding permissions, core will collect grants from all node access modules via node_access_acquire_grants and only the ones with the highest priority win. This may result in different data and thus in unreliable node access.
