Git 2.24 Release Notes
======================

Updates since v2.23
-------------------

Backward compatibility note

 * (no entry yet so far)


UI, Workflows & Features

 * The command line parser learned "--end-of-options" notation; the
   standard convention for scripters to have hardcoded set of options
   first on the command line, and force the command to treat end-user
   input as non-options, has been to use "--" as the delimiter, but
   that would not work for commands that use "--" as a delimiter
   between revs and pathspec.

 * A mechanism to affect the default setting for a (related) group of
   configuration variables is introduced.

 * "git fetch" learned "--set-upstream" option to help those who first
   clone from their private fork they intend to push to, add the true
   upstream via "git remote add" and then "git fetch" from it.

 * Device-tree files learned their own userdiff patterns.
   (merge 3c81760bc6 sb/userdiff-dts later to maint).


Performance, Internal Implementation, Development Support etc.

 * The code to write commit-graph over given commit object names has
   been made a bit more robust.

 * The first line of verbose output from each test piece now carries
   the test name and number to help scanning with eyeballs.

 * Further clean-up of the initialization code.


Fixes since v2.23
-----------------

 * "git grep --recurse-submodules" that looks at the working tree
   files looked at the contents in the index in submodules, instead of
   files in the working tree.
   (merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).

 * Codepaths to walk tree objects have been audited for integer
   overflows and hardened.
   (merge 5aa02f9868 jk/tree-walk-overflow later to maint).

 * "git pack-refs" can lose refs that are created while running, which
   is getting corrected.
   (merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).

 * "git checkout" and "git restore" to re-populate the index from a
   tree-ish (typically HEAD) did not work correctly for a path that
   was removed and then added again with the intent-to-add bit, when
   the corresponding working tree file was empty.  This has been
   corrected.

 * Compilation fix.
   (merge 70597e8386 rs/nedalloc-fixlets later to maint).

 * "git gui" learned to call the clean-up procedure before exiting.
   (merge 0d88f3d2c5 py/git-gui-do-quit later to maint).

 * We promoted the "indent heuristics" that decides where to split
   diff hunks from experimental to the default a few years ago, but
   some stale documentation still marked it as experimental, which has
   been corrected.
   (merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).

 * Fix a mismerge that happened in 2.22 timeframe.
   (merge acb7da05ac en/checkout-mismerge-fix later to maint).

 * "git archive" recorded incorrect length in extended pax header in
   some corner cases, which has been corrected.
   (merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).

 * On-demand object fetching in lazy clone incorrectly tried to fetch
   commits from submodule projects, while still working in the
   superproject, which has been corrected.
   (merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).

 * Prepare get_short_oid() codepath to be thread-safe.
   (merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).

 * "for-each-ref" and friends that show refs did not protect themselves
   against ancient tags that did not record tagger names when asked to
   show "%(taggername)", which have been corrected.
   (merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).

 * The "git am" based backend of "git rebase" ignored the result of
   updating ".gitattributes" done in one step when replaying
   subsequent steps.
   (merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge d1387d3895 en/fast-import-merge-doc later to maint).
   (merge 1c24a54ea4 bm/repository-layout-typofix later to maint).
   (merge 415b770b88 ds/midx-expire-repack later to maint).
   (merge 19800bdc3f nd/diff-parseopt later to maint).
   (merge 58166c2e9d tg/t0021-racefix later to maint).
