Checking the git log against the submission date it's almost certainly one of these:

commit 94d107ea0ce2772359ee7d09041abd920ec8b8bb
Author: Lasse Collin <lasse.collin at tukaani.org>

    Add support for MSVC in xz_config.h.

    Thanks to Luke Deller for the original patch.

    Add optional support for CRC64.

commit e111c275da8b88749dc9cc8d2adce9872a611b89
Author: Lasse Collin <lasse.collin at tukaani.org>
Date:   Sat Mar 31 10:39:09 2012 +0300

    Mention xzminidec.c in README.


Most likely it's the 2012 commit with the one year gap after it. It was
submitted in march so the April commit at the top happened after the submission,
and the integrity check #defines commit only touched the README, so the question
is does the submission have CRC64 or not... and yes it does.

So it came from https://git.tukaani.org/xz-embedded.git commit 0568cfabccc8.
Which means:

  $ git log | grep '^commit' | sed '/0568cfabccc8/Q' | wc -l
  31

31 commits to examine for interesting updates. I'll throw it on the todo heap,
unless Oliver wants to take that one. :)
