Git 2.33 Release Notes
======================

Backward compatibility notes
----------------------------

 * The "-m" option in "git log -m" that does not specify which format,
   if any, of diff is desired did not have any visible effect; it now
   implies some form of diff (by default "--patch") is produced.

   You can disable the diff output with "git log -m --no-patch", but
   then there probably isn't much point in passing "-m" in the first
   place ;-).


Updates since Git 2.32
----------------------

UI, Workflows & Features

 * "git send-email" learned the "--sendmail-cmd" command line option
   and the "sendemail.sendmailCmd" configuration variable, which is a
   more sensible approach than the current way of repurposing the
   "smtp-server" that is meant to name the server to instead name the
   command to talk to the server.

 * The "-m" option in "git log -m" that does not specify which format,
   if any, of diff is desired did not have any visible effect; it now
   implies some form of diff (by default "--patch") is produced.


Performance, Internal Implementation, Development Support etc.

 * The code to handle the "--format" option in "for-each-ref" and
   friends made too many string comparisons on %(atom)s used in the
   format string, which has been corrected by converting them into
   enum when the format string is parsed.

 * Use the hashfile API in the codepath that writes the index file to
   reduce code duplication.

 * Repeated rename detections in a sequence of mergy operations have
   been optimize out.


Fixes since v2.32
-----------------

 * We historically rejected a very short string as an author name
   while accepting a patch e-mail, which has been loosened.
   (merge 72ee47ceeb ef/mailinfo-short-name later to maint).

 * The parallel checkout codepath did not initialize object ID field
   used to talk to the worker processes in a futureproof way.

 * Rewrite code that triggers undefined behaviour warning.
   (merge aafa5df0df jn/size-t-casted-to-off-t-fix later to maint).

 * The description of "fast-forward" in the glossary has been updated.
   (merge e22f2daed0 ry/clarify-fast-forward-in-glossary later to maint).

 * Recent "git clone" left a temporary directory behind when the
   transport layer returned an failure.
   (merge 6aacb7d861 jk/clone-clean-upon-transport-error later to maint).

 * "git fetch" over protocol v2 left its side of the socket open after
   it finished speaking, which unnecessarily wasted the resource on
   the other side.
   (merge ae1a7eefff jk/fetch-pack-v2-half-close-early later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge bfe35a6165 ah/doc-describe later to maint).
   (merge f302c1e4aa jc/clarify-revision-range later to maint).
   (merge 3127ff90ea tl/fix-packfile-uri-doc later to maint).
   (merge a84216c684 jk/doc-color-pager later to maint).
