Git 2.26 Release Notes
======================
 
Updates since v2.25
-------------------
 
UI, Workflows & Features
 
 * Sample credential helper for using .netrc has been updated to work
   out of the box.
 
 * gpg.minTrustLevel configuration variable has been introduced to
   tell various signature verification codepaths the required minimum
   trust level.
 
 * The command line completion (in contrib/) learned to complete
   subcommands and arguments to "git worktree".
 
 * Disambiguation logic to tell revisions and pathspec apart has been
   tweaked so that backslash-escaped glob special characters do not
   count in the "wildcards are pathspec" rule.
 
 * One effect of specifying where the GIT_DIR is (either with the
   environment variable, or with the "git --git-dir=<where> cmd"
   option) is to disable the repository discovery.  This has been
   placed a bit more stress in the documentation, as new users often
   get confused.
 
 * Two help messages given when "git add" notices the user gave it
   nothing to add have been updated to use advise() API.
 
 * A new version of fsmonitor-watchman hook has been introduced, to
   avoid races.
 
 * "git config" learned to show in which "scope", in addition to in
   which file, each config setting comes from.
 
 * The basic 7 colors learned the brighter counterparts
   (e.g. "brightred").
 
 
Performance, Internal Implementation, Development Support etc.
 
 * Tell .editorconfig that in this project, *.txt files are indented
   with tabs.
 
 * The test-lint machinery knew to check "VAR=VAL shell_function"
   construct, but did not check "VAR= shell_funciton", which has been
   corrected.
 
 * Replace "git config --bool" calls with "git config --type=bool" in
   sample templates.
 
 * The effort to move "git-add--interactive" to C continues.
 
 * Improve error message generation for "git submodule add".
 
 * Preparation of test scripts for the day when the object names will
   use SHA-256 continues.
 
 * Warn programmers about pretend_object_file() that allows the code
   to tentatively use in-core objects.
 
 * The way "git pack-objects" reuses objects stored in existing pack
   to generate its result has been improved.
 
 * The transport protocol version 2 becomes the default one.
 
 * Traditionally, we avoided threaded grep while searching in objects
   (as opposed to files in the working tree) as accesses to the object
   layer is not thread-safe.  This limitation is getting lifted.
 
 * "git rebase -i" (and friends) used to unnecessarily check out the
   tip of the branch to be rebased, which has been corrected.
 
 * A low-level API function get_oid(), that accepts various ways to
   name an object, used to issue end-user facing error messages
   without l10n, which has been updated to be translatable.
 
 * Unneeded connectivity check is now disabled in a partial clone when
   fetching into it.
 
 * Some rough edges in the sparse-checkout feature, especially around
   the cone mode, have been cleaned up.
 
 * The diff-* plumbing family of subcommands now pay attention to the
   diff.wsErrorHighlight configuration, which has been ignored before;
   this allows "git add -p" to also show the whitespace problems to
   the end user.
 
 * Some codepaths were given a repository instance as a parameter to
   work in the repository, but passed the_repository instance to its
   callees, which has been cleaned up (somewhat).
 
 * Memory footprint and performance of "git name-rev" has been
   improved.
 
 
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.
 
 * Complete an update to tutorial that encourages "git switch" over
   "git checkout" that was done only half-way.
 
 * C pedantry ;-) fix.
 
 * 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.
 
 * 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.
 
 * Rendering by "git log --graph" of ancestry lines leading to a merge
   commit were made suboptimal to waste vertical space a bit with a
   recent update, 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.
 
 * Minor bugfixes to "git add -i" that has recently been rewritten in C.
   (merge 849e43cc18 js/builtin-add-i-cmds later to maint).
 
 * "git fetch --refmap=" option has got a better documentation.
 
 * "git checkout X" did not correctly fail when X is not a local
   branch but could name more than one remote-tracking branches
   (i.e. to be dwimmed as the starting point to create a corresponding
   local branch), which has been corrected.
   (merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
 
 * 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.
 
 * A fetch that is told to recursively fetch updates in submodules
   inevitably produces reams of output, and it becomes hard to spot
   error messages.  The command has been taught to enumerate
   submodules that had errors at the end of the operation.
   (merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
 
 * The "--recurse-submodules" option of various subcommands did not
   work well when run in an alternate worktree, which has been
   corrected.
   (merge a9472afb63 pb/recurse-submodule-in-worktree-fix later to maint).
 
 * Futureproofing a test not to depend on the current implementation
   detail.
 
 * Running "git rm" on a submodule failed unnecessarily when
   .gitmodules is only cache-dirty, which has been corrected.
   (merge 7edee32985 dt/submodule-rm-with-stale-cache later to maint).
 
 * C pedantry ;-) fix.
   (merge cf82bff73f jk/clang-sanitizer-fixes later to maint).
 
 * "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.
 
 * "git rebase -i" identifies existing commits in its todo file with
   their abbreviated object name, which could become ambigous as it
   goes to create new commits, and has a mechanism to avoid ambiguity
   in the main part of its execution.  A few other cases however were
   not covered by the protection against ambiguity, which has been
   corrected.
   (merge 26027625dd js/rebase-i-with-colliding-hash later to maint).
 
 * Allow the rebase.missingCommitsCheck configuration to kick in when
   "rebase --edit-todo" and "rebase --continue" restarts the procedure.
   (merge 5a5445d878 ag/edit-todo-drop-check later to maint).
 
 * The way "git submodule status" reports an initialized but not yet
   populated submodule has not been reimplemented correctly when a
   part of the "git submodule" command was rewritten in C, which has
   been corrected.
   (merge f38c92452d pk/status-of-uncloned-submodule later to maint).
 
 * The code to automatically shrink the fan-out in the notes tree had
   an off-by-one bug, which has been killed.
   (merge dbc27477ff jh/notes-fanout-fix later to maint).
 
 * The index-pack code now diagnoses a bad input packstream that
   records the same object twice when it is used as delta base; the
   code used to declare a software bug when encountering such an
   input, but it is an input error.
   (merge a21781011f jk/index-pack-dupfix later to maint).
 
 * The code to compute the commit-graph has been taught to use a more
   robust way to tell if two object directories refer to the same
   thing.
   (merge a7df60cac8 tb/commit-graph-object-dir later to maint).
 
 * "git remote rename X Y" needs to adjust configuration variables
   (e.g. branch.<name>.remote) whose value used to be X to Y.
   branch.<name>.pushRemote is now also updated.
 
 * Other code cleanup, docfix, build fix, etc.
   (merge 26f924d50e en/simplify-check-updates-in-unpack-trees later to maint).
   (merge d0d0a357a1 am/update-pathspec-f-f-tests later to maint).
   (merge f94f7bd00d am/test-pathspec-f-f-error-cases later to maint).
