id software Designer Graeme Devine updated his .plan with word on duplicatable problems in the upcoming full version of Mac Q3A that he's fixed, resulting in a new release candidate, and a mention of some unduplicatable problems with the demo that he's still uncertain about, resulting in some confusion. The update also briefly mentions a planned Q3A point release:

While I've been out with the rest of the world trying to get a Barbie Cash Register for my daughter, I have actually been doing a bit of work!

Activision's release QA process found two bugs in the Mac build that I felt important enough to fix. One bug was in the client, and the other in the installer.

I fixed them both last night and Activision has a new master candidate.

I've heard sporadic reports that the Mac demo has problems, but I've yet to be able to repeat that issue here.

I'll update my plan file today with the [long] list of things we're addressing for the point release (yes, we've fixed the scoreboard).
