Eh, of course the addition should go to 2.17 release notes ;-)  I
just happened to be reviewing a topic forked earlier.

Thanks for noting.  I agree that this is not something that requires
more than a mention near the beginning of release notes.

I haven't wordsmithed it fully, but it should say something along
the lines of ...

I've just noticed this now, but while this module is in 5.8 RedHat's
butchered perl doesn't have it in the base system, thus this introduces
the do-we-even-care regression that git's full test suite won't pass on
a RedHat (or CentOS) base system, because the gitweb tests will fail to
"use" Digest::MD5.

I'm slightly leaning towards not caring about it, since there's no other
perl distributor that does this sort of split-out of the core, and if
you're on a RedHat system they're solving your package problems, so this
really only impacts the edge case of git developers and redhat
packagers, both of whom can just do "yum install -y perl-Digest-MD5" to
fix it.

Git 2.17 Release Notes (draft)
==

Updates since v2.16
---

UI, Workflows & Features

 * "diff" family of commands learned "--find-object=" option
   to limit the findings to changes that involve the named object.

 * "git format-patch" learned to give 72-cols to diffstat, which is
   consistent with other line length limits the subcommand uses for
   its output meant for e-mails.

 * The log from "git daemon" can be redirected with a new option; one
   relevant use case is to send the log to standard error (instead of
   syslog) when running it from inetd.

 * "git rebase" learned to take "--allow-empty-message" option.

 * "git am" has learned the "--quit" option, in addition to the
   existing "--abort" option; having the pair mirrors a few other
   commands like "rebase" and "cherry-pick".

 * "git worktree add" learned to run the post-checkout hook, just like
   "git clone" runs it upon the initial checkout.

 * "git tag" learned an explicit "--edit" option that allows the
   message given via "-m" and "-F" to be further edited.

 * "git fetch --prune-tags" may be used as a handy short-hand for
   getting rid of stale tags that are locally held.

 * The new "--show-current-patch" option gives an end-user facing way
   to get the diff being applied when "git rebase" (and "git am")
   stops with a conflict.

 * "git add -p" used to offer "/" (look for a matching hunk) as a
   choice, even there was only one hunk, which has been corrected.
   Also the single-key help is now given only for keys that are
   enabled (e.g. help for '/' won't be shown when there is only one
   hunk).

 * Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when
   the side branch being merged is a descendant of the current commit,
   create a merge commit instead of fast-forwarding) when merging a
   tag object.  This was appropriate default for integrators who pull
   signed tags from their downstream contributors, but caused an
   unnecessary merges when used by downstream contributors who
   habitually "catch up" their topic branches with tagged releases
   from the upstream.  Update "git merge" to default to --no-ff only
   when merging a tag object that does *not* sit at its usual place in
   refs/tags/ hierarchy, and allow fast-forwarding otherwise, to
   mitigate the problem.

 * "git status" can spend a lot of cycles to compute the relation
   between the current branch and its upstream, which can now be
   disabled with "--no-ahead-behind" option.

 * "git diff" and friends learned funcname patterns for Go language
   source files.

 * "git send-email" learned "--reply-to=" option.

 * Funcname pattern used for C# now recognizes "async" keyword.


Performance, Internal Implementation, Development Support etc.

 * More perf tests for threaded grep

 * "perf" test output can be sent to codespeed server.

 * The build procedure for perl/ part has been greatly simplified by
   weaning ourselves off of MakeMaker.

 * In preparation for implementing narrow/partial clone, the machinery
   for checking object connectivity used by gc and fsck has been
