I just upgraded 25.5.1  via git pull and recompiling.

Then I noted (to my horror (personal opinion) that the behavior of
hg-modeline was changed.

The relevant log entry is this:

I wanted the old behavior and I thought I just set 
 vc-hg-use-file-version-for-mode-line-version to t.

But then HG-hash is displayed not HG-rev.
