History of AutoCAD versions

Anyone know the years of release for AutoCAD (and LT) going back over the years?
I have a pretty good idea when 2004, 2002, 2000i, 2000, R14 and R13 were released, but wondered if there was a definitive list somewhere. Better still, a list showing significant changes with each release.
What about R15? Was there ever such a thing? I have came across some references to it.
Thanks.

Full AutoCAD:
Version 1.0 (Release 1) - December, 1982 Version 1.2 (Release 2) - April, 1983 Version 1.3 (Release 3) - August, 1983 Version 1.4 (Release 4) - October, 1983 Version 2.0 (Release 5) - October, 1984 Version 2.1 (Release 6) - May, 1985 Version 2.5 (Release 7) - June, 1986 Version 2.6 (Release 8) - April, 1987 Release 9 - September, 1987 Release 10 - October, 1988 Release 11 - October, 1990 Release 12 - June, 1992 Release 13 - November, 1994 Release 14 - February, 1997 2000 (Tahoe) - April, 1999 2000i (Banff) - July, 2000 2002 - Late 2001 2004 - Early 2003
After the first release of LT (sorry I don't have the dates or version numbers) there were introductions within a few weeks either side of the full AutoCAD releases. Maybe someone else has tracked those ... ___

I have a copy of AutoCAD LT for Windows (3.1) still running on my Laptop (release date was December 1993). It still works although I hardly use it anymore because it's not quite so functional as AutoCAD 2002.

A2K would have been r15 but AutoDesk knew about the odd numbered release curse, and so cleverly changed strategies. Calling it r15 draws comparison with the earlier, slower/buggier odd numbered releases.
