Git v2.41 Release Notes
=======================

UI, Workflows & Features

 * Allow information carried on the WWW-AUthenticate header to be
   passed to the credential helpers.

 * A new "fetch.hideRefs" option can be used to exclude specified refs
   from "rev-list --objects --stdin --not --all" traversal for
   checking object connectivity, most useful when there are many
   unrelated histories in a single repository.

 * "git push" has been taught to allow deletion of refs with one-level
   names to help repairing a repository who acquired such a ref by
   mistake.  In general, we don't encourage use of such a ref, and
   creation or update to such a ref is rejected as before.

 * Allow "git bisect reset" to check out the original branch when the
   branch is already checked out in a different worktree linked to the
   same repository.

 * A few subcommands have been taught to stop users from working on a
   branch that is being used in another worktree linked to the same
   repository.

 * "git format-patch" learned to write a log-message only output file
   for empty commits.

 * "git format-patch" honors the src/dst prefixes set to nonstandard
   values with configuration variables like "diff.noprefix", causing
   receiving end of the patch that expects the standard -p1 format to
   break.  "format-patch" has been taught to ignore end-user configuration
   and always use the standard prefixes.

   This is a backward compatibility breaking change.


Performance, Internal Implementation, Development Support etc.

 * Code clean-up to clarify directory traversal API.

 * Code clean-up to clarify the rule that "git-compat-util.h" must be
   the first to be included.

 * More work towards -Wunused.

 * Instead of forcing each command to choose to honor GPG related
   configuration variables, make the subsystem lazily initialize
   itself.


Fixes since v2.40
-----------------

 * "git fsck" learned to check the index files in other worktrees,
   just like "git gc" honors them as anchoring points.
   (merge 8d3e7eac52 jk/fsck-indices-in-worktrees later to maint).

 * Fix a segfaulting loop.  The function and its caller may need
   further clean-up.
   (merge c5773dc078 ew/commit-reach-clean-up-flags-fix later to maint).

 * "git restore" supports options like "--ours" that are only
   meaningful during a conflicted merge, but these options are only
   meaningful when updating the working tree files.  These options are
   marked to be incompatible when both "--staged" and "--worktree" are
   in effect.
   (merge ee8a88826a ak/restore-both-incompatible-with-conflicts later to maint).

 * Simplify UI to control progress meter given by "git bundle" command.
   (merge 8b95521edb jk/bundle-progress later to maint).

 * "git bundle" learned that "-" is a common way to say that the input
   comes from the standard input and/or the output goes to the
   standard output.  It used to work only for output and only from the
   root level of the working tree.
   (merge 0bbe10313e jk/bundle-use-dash-for-stdfiles later to maint).

 * Once we start running, we assumed that the list of alternate object
   databases would never change.  Hook into the machinery used to
   update the list of packfiles during runtime to update this list as
   well.
   (merge e2d003dbed ds/reprepare-alternates-when-repreparing-packfiles later to maint).

 * The code to parse "git rebase -X<opt>" was not prepared to see an
   unparsable option string, which has been corrected.
   (merge 15a4cc912e ab/fix-strategy-opts-parsing later to maint).

 * "git add -p" while the index is unmerged sometimes failed to parse
   the diff output it internally produces and died, which has been
   corrected.
   (merge 28d1122f9c jk/add-p-unmerged-fix later to maint).

 * Fix for a "ls-files --format="%(path)" that produced nonsense
   output, which was a bug in 2.38.
   (merge cfb62dd006 aj/ls-files-format-fix later to maint).

 * "git receive-pack" that responds to "git push" requests failed to
   clean a stale lockfile when killed in the middle, which has been
   corrected.
   (merge c55c30669c ps/receive-pack-unlock-before-die later to maint).

 * Other code cleanup, docfix, build fix, etc.
   (merge f7111175df as/doc-markup-fix later to maint).
   (merge 90ff7c9898 fc/test-aggregation-clean-up later to maint).
