It might well have been this change:

commit 63dd1c6fa45357d312e1d3076e15adacf5ed6291
Author: Juri Linkov <juri@jurta.org>
Date:   Sun Sep 2 12:31:45 2012 +0300

    Toggle whitespace matching mode with M-s SPC.

We have given up updating the ChangeLogs with each change, on the
grounds that the information is in the git change log anyway.  I think
the idea is to generate the full ChangeLogs as part of the release
process.

From anywhere inside a local copy of the git repository, type "git log"
(no arguments) on a command line.  This should dump the entire log into
`less'.  You can then search within that (as I have just done).

There will certainly also be a way of getting the log from inside Emacs.
