Git v2.39.3 Release Notes
=========================

This release is primarily to merge fixes accumulated on the 'master'
front to prepare for 2.40 release that are still relevant to 2.39.x
maintenance track.

Fixes since v2.39.2
-------------------

 * Stop running win+VS build by default.

 * CI updates.  We probably want a clean-up to move the long shell
   script embedded in yaml file into a separate file, but that can
   come later.

 * Avoid unnecessary builds in CI, with settings configured in
   ci-config.

 * Redefining system functions for a few functions did not follow our
   usual "implement git_foo() and #define foo(args) git_foo(args)"
   pattern, which has broken build for some folks.

 * Deal with a few deprecation warning from cURL library.

 * Newer regex library macOS stopped enabling GNU-like enhanced BRE,
   where '\(A\|B\)' works as alternation, unless explicitly asked with
   the REG_ENHANCED flag.  "git grep" now can be compiled to do so, to
   retain the old behaviour.

 * When given a pattern that matches an empty string at the end of a
   line, the code to parse the "git diff" line-ranges fell into an
   infinite loop, which has been corrected.

 * Fix the sequence to fsync $GIT_DIR/packed-refs file that forgot to
   flush its output to the disk..

 * "git diff --relative" did not mix well with "git diff --ext-diff",
   which has been corrected.

 * The logic to see if we are using the "cone" mode by checking the
   sparsity patterns has been tightened to avoid mistaking a pattern
   that names a single file as specifying a cone.

 * Doc update for environment variables set when hooks are invoked.

 * Document ORIG_HEAD a bit more.

 * "git ls-tree --format='%(path) %(path)' $tree $path" showed the
   path three times, which has been corrected.

 * Document that "branch -f <branch>" disables only the safety to
   avoid recreating an existing branch.

 * Clarify how "checkout -b/-B" and "git branch [-f]" are similar but
   different in the documentation.

Also contains minor documentation updates and code clean-ups.
