Kevin, Does head currently work for you with the new Allegro (and with 9.0) on all three platforms? If so, I'm inclined to suggest we bless this as 3.1.6, since I know of no regressions on other implementations. Out of a sense of tidiness, I'd be happier if you had an x.y.z release version in your released ACL, instead of some transient internal version. But I'm going to be quite busy for the remainder of the month, so if you could let me know ASAP, I will try to squeeze the release around other activities in time that you can incorporate it in ACL. For you, ideally, it should just be a matter of getting a version with a tidier release number. Cheers, Robert
