I have upgraded from 1.115 to 1.122 today. Build for our projects is triggered
by changes in svn. We are using user name & password to access svn.

After the upgrade quite often the build gets triggered even when there are no
changes in the svn (it even says no changes on the build page). Also while a
build is running another build for the same project gets added to teh queue and
starts right away after the previous buidl is done (ignoring the quite period
settings)

(you are doign an amazing job with Hudson, i can't believe we were able to
exist without it before we switched about 4 months ago!)
