POE 1.280 has just been released, but it may take up to a day before your favorite CPAN mirror catches wind of it. You'll also need the latest POE::Test::Loops, version 1.030.
Those following along may notice that the version numbers jumped a little. That's because POE has undergone a couple optimizations that alter its behavior a little.
I/O Dispatch is Faster
I/O events jump the queue in POE 1.280. Skipping an enqueue and dequeue saves significant time. The drawback is that I/O is dispatched in a different order relative to other kinds of events. Most people won't care, but it has affected one of POE::Component::Client::HTTP's tests. See below for contact information if you think it's affected you.
Session Cleanup is Faster
In POE 1.280, session cleanup is done just before the event loop would wait for new events. Programs that aren't event bound should show decreased latency because the cleanup will be scheduled during idle times. This optimization changes the timing of session cleanup and their resulting _stop events. While I don't think it affects many people, it has already bitten Adam Kennedy. Please let us know if you suspect it's gnawing on you, too.
