fix: publisher got a 201 Created response even if the channel had no subscribers at the time (should be 202 Accepted) fix: small memory leak after each message broadcast to a channel feature: optional push_max_channel_subscribers setting added fix: first-in concurrency setting wasn't responding to subscribers with a correct status code on conflict fix: reused subscriber connections sometimes failed to receive messages unfeature: no more nginx 0.6 support. not worth the hassle.
