Git 2.37.4 Release Notes
========================

This primarily is to backport various fixes accumulated on the 'master'
front since 2.37.3.

Fixes since v2.37.3
-------------------

 * An earlier optimization discarded a tree-object buffer that is
   still in use, which has been corrected.

 * Fix deadlocks between main Git process and subprocess spawned via
   the pipe_command() API, that can kill "git add -p" that was
   reimplemented in C recently.

 * xcalloc(), imitating calloc(), takes "number of elements of the
   array", and "size of a single element", in this order.  A call that
   does not follow this ordering has been corrected.

 * The preload-index codepath made copies of pathspec to give to
   multiple threads, which were left leaked.

 * Update the version of Ubuntu used for GitHub Actions CI from 18.04
   to 22.04.

 * The auto-stashed local changes created by "git merge --autostash"
   was mixed into a conflicted state left in the working tree, which
   has been corrected.

Also contains other minor documentation updates and code clean-ups.
