For the relevant changes, I think the proper dates would be around revisions 1.44.2.23.2.21 -> -r1.44.2.23.2.23 of the file src/sys/conf/newvers.sh which yield the following date tags: % cvs diff -D '2002/10/26 21:00:00 UTC' -D '2003/01/06 12:45:00 UTC' Run this in /src and you'll find out all the changes. I have moved the dates slightly backward <-> forward, to catch commits that happened in a short timeframe around the change to newvers.sh - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
