rsync - Jul 2016 - rsync v3.0.7 on Cygwin not updating larger but older dest file using "-u" option

All,

I am using an older version of rsync (v3.0.7) on top of Cygwin on Windows, with
a remote rsyncd.  I am using "rsync -azhu  SOURCEDIR DESTDIR" so that
I can update the DEST only if it has an older version of an existing file
(people work at both sites, and I don't want to overwrite the most recent
version of a file).  I'm finding that if I update a file under SOURCEDIR and
make it larger, everything works as expected and DEST is updated.  However, if I
update a file and it becomes smaller, the older DEST file remains untouched.  I
did not see anything in the rsync changelog from v3.0.7 through the current
version that appeared to be a fix for this behavior.  Has anyone else
experienced this behavior, and if so, with what version of rsync?  Thanks in
advance!

Martin G.
