As a reminder, we're expecting the release of 4.5.5 in a few days, so if there are any last-minute fixes this is a good time to finish them.
I think it will be good to release another prerelease version of 4.6.0 as well, though I'm uncertain whether I want to call it "beta" or "rc1" (I'm leaning towards rc1), which I may do at the same time (probably as two different announcements, though). I feel 4.6.0-alpha1 went quite well and I'm eager for the official 4.6.0 release.
Objections or agreements are welcome.
