I've seen release circuses before, I even had a ring-side seat for the last one, but this is my first from inside the ring.
In case you've been living under a rock, you've probably heard that OpenSSH has some buffer management issues. The jury is still out on whether or not it's explotable, but regardless, there was a massive scramble for release. If you haven't already, you should apply the patch or upgrade.
Naturally, since it was a rush release, there was breakage. Despite requests to test for the impending release, it looks like no-one with (IRIX, Tru64, BSDi, MacOS X) ever tested it and those are all broken. There are also other issues with certain configurations (including, sadly, one I'm responsible for). You can check the score over at bugzilla. Meanwhile, the list server is melting down (currently ~12 hours behind, but still delivering!)
By coincidence, my next job was postponed by the customer (again!), so I've been on deck juggling as many of the bug reports as I can. If you get only a terse response from me (or none), that's why.
