Git 2.25.1 Release Notes
========================

Fixes since v2.25
-----------------

 * "git commit" gives output similar to "git status" when there is
   nothing to commit, but without honoring the advise.statusHints
   configuration variable, which has been corrected.

 * has_object_file() said "no" given an object registered to the
   system via pretend_object_file(), making it inconsistent with
   read_object_file(), causing lazy fetch to attempt fetching an
   empty tree from promisor remotes.

 * The code that tries to skip over the entries for the paths in a
   single directory using the cache-tree was not careful enough
   against corrupt index file.

 * Complete an update to tutorial that encourages "git switch" over
   "git checkout" that was done only half-way.

 * Reduce unnecessary round-trip when running "ls-remote" over the
   stateless RPC mechanism.

 * "git restore --staged" did not correctly update the cache-tree
   structure, resulting in bogus trees to be written afterwards, which
   has been corrected.

 * The code recently added to move to the entry beyond the ones in the
   same directory in the index in the sparse-cone mode did not count
   the number of entries to skip over incorrectly, which has been
   corrected.

 * Work around test breakages caused by custom regex engine used in
   libasan, when address sanitizer is used with more recent versions
   of gcc and clang.

 * "git fetch --refmap=" option has got a better documentation.

 * Corner case bugs in "git clean" that stems from a (necessarily for
   performance reasons) awkward calling convention in the directory
   enumeration API has been corrected.

 * "git grep --no-index" should not get affected by the contents of
   the .gitmodules file but when "--recurse-submodules" is given or
   the "submodule.recurse" variable is set, it did.  Now these
   settings are ignored in the "--no-index" mode.

 * Technical details of the bundle format has been documented.

 * Unhelpful warning messages during documentation build have been
   squelched.

Also contains various documentation updates, code clean-ups and minor fixups.
