The UPDATING file is in the same location for all tags/branches:
/usr/src/UPDATING

Please note that the excerpt mm@ provided is from HEAD/9-CURRENT; said
excerpt isn't in RELENG_8, so you wouldn't have found this information.
Validation of my statement:

http://www.freebsd.org/cgi/cvsweb.cgi/src/UPDATING#rev.1661

This is from HEAD ("Branches: MAIN").
