+Git v2.38 Release Notes
+=======================
+
+UI, Workflows & Features
+
+ * "git remote show [-n] frotz" now pays attention to negative
+ pathspec.
+
+ * "git push" sometimes perform poorly when reachability bitmaps are
+ used, even in a repository where other operations are helped by
+ bitmaps. The push.useBitmaps configuration variable is introduced
+ to allow disabling use of reachability bitmaps only for "git push".
+
+ * "git grep -m<max-hits>" is a way to limit the hits shown per file.
+
+ * "git merge-tree" learned a new mode where it takes two commits and
+ computes a tree that would result in the merge commit, if the
+ histories leading to these two commits were to be merged.
+
+ * "git mv A B" in a sparsely populated working tree can be asked to
+ move a path between directories that are "in cone" (i.e. expected
+ to be materialized in the working tree) and "out of cone"
+ (i.e. expected to be hidden). The handling of such cases has been
+ improved.
+
+ * Earlier, HTTP transport clients learned to tell the server side
+ what locale they are in by sending Accept-Language HTTP header, but
+ this was done only for some requests but not others.
+
+ * Introduce a discovery.barerepository configuration variable that
+ allows users to forbid discovery of bare repositories.
+
+ * Various messages that come from the pack-bitmap codepaths have been
+ tweaked.
+
+ * "git rebase -i" learns to update branches whose tip appear in the
+ rebased range with "--update-refs" option.
+
+ * "git ls-files" learns the "--format" option to tweak its output.
+
+ * "git cat-file" learned an option to use the mailmap when showing
+ commit and tag objects.
+
+ * When "git merge" finds that it cannot perform a merge, it should
+ restore the working tree to the state before the command was
+ initiated, but in some corner cases it didn't.
+
+ * Operating modes like "--batch" of "git cat-file" command learned to
+ take NUL-terminated input, instead of one-item-per-line.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Collection of what is referenced by objects in promisor packs have
+ been optimized to inspect these objects in the in-pack order.
+
+ * Introduce a helper to see if a branch is already being worked on
+ (hence should not be newly checked out in a working tree), which
+ performs much better than the existing find_shared_symref() to
+ replace many uses of the latter.
+
+ * Teach "git archive" to (optionally and then by default) avoid
+ spawning an external "gzip" process when creating ".tar.gz" (and
+ ".tgz") archives.
+
+ * Allow large objects read from a packstream to be streamed into a
+ loose object file straight, without having to keep it in-core as a
+ whole.
+
+ * Further preparation to turn git-submodule.sh into a builtin
+ continues.
+
+ * Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp
+ macro, which would improve maintainability and readability.
+
+ * Teach "make all" to build gitweb as well.
+
+ * Tweak tests so that they still work when the "git init" template
+ did not create .git/info directory.
+
+ * Add Coccinelle rules to detect the pattern of initializing and then
+ finalizing a structure without using it in between at all, which
+ happens after code restructuring and the compilers fail to
+ recognize as an unused variable.
+
+ * The code to convert between GPG trust level strings and internal
+ constants we use to represent them have been cleaned up.
+
+ * Support for libnettle as SHA256 implementation has been added.
+
+ * The way "git multi-pack" uses parse-options API has been improved.
+
+ * A coccinelle rule (in contrib/) to encourage use of COPY_ARRAY
+ macro has been improved.
+
+ * API tweak to make it easier to run fuzz testing on commit-graph parser.
+
+ * Omit fsync-related trace2 entries when their values are all zero.
+
+ * The codepath to write multi-pack index has been taught to release a
+ large chunk of memory that holds an array of objects in the packs,
+ as soon as it is done with the array, to reduce memory consumption.
+
+ * Add a level of redirection to array allocation API in xdiff part,
+ to make it easier to share with the libgit2 project.
+
+ * "git fetch" client logs the partial clone filter used in the trace2
+ output.
+
+
+Fixes since v2.37
+-----------------
+
+ * Rewrite of "git add -i" in C that appeared in Git 2.25 didn't
+ correctly record a removed file to the index, which was fixed.
+
+ * Certain diff options are currently ignored when combined-diff is
+ shown; mark them as incompatible with the feature.
+
+ * Adjust technical/bitmap-format to be formatted by AsciiDoc, and
+ add some missing information to the documentation.
+
+ * Fixes for tests when the source directory has unusual characters in
+ its path, e.g. whitespaces, double-quotes, etc.
+
+ * "git mktree --missing" lazily fetched objects that are missing from
+ the local object store, which was totally unnecessary for the purpose
+ of creating the tree object(s) from its input.
+
+ * Give _() markings to fatal/warning/usage: labels that are shown in
+ front of these messages.
+
+ * References to commands-to-be-typed-literally in "git rebase"
+ documentation mark-up have been corrected.
+
+ * In a non-bare repository, the behavior of Git when the
+ core.worktree configuration variable points at a directory that has
+ a repository as its subdirectory, regressed in Git 2.27 days.
+
+ * Recent update to vimdiff layout code has been made more robust
+ against different end-user vim settings.
+
+ * Plug various memory leaks.
+ (merge ece3974ba6 ab/leakfix later to maint).
+
+ * Plug various memory leaks in test-tool commands.
+ (merge f40a693450 ab/test-tool-leakfix later to maint).
+
+ * Fixes a long-standing corner case bug around directory renames in
+ the merge-ort strategy.
+
+ * The resolve-undo information in the index was not protected against
+ GC, which has been corrected.
- (merge cb88b37cb9 hx/lookup-commit-in-graph-fix later to maint).
+
+ * A corner case bug where lazily fetching objects from a promisor
+ remote resulted in infinite recursion has been corrected.
- (merge 4d35f74421 mb/p4-utf16-crlf later to maint).
+
+ * "git clone" from a repository with some ref whose HEAD is unborn
+ did not set the HEAD in the resulting repository correctly, which
+ has been corrected.
+
+ * An earlier attempt to plug leaks placed a clean-up label to jump to
+ at a bogus place, which as been corrected.
+
+ * Variable quoting fix in the vimdiff driver of "git mergetool"
+
+ * "git shortlog -n" relied on the underlying qsort() to be stable,
+ which shouldn't have. Fixed.
+
+ * A fix for a regression in test framework.
+
+ * mkstemp() emulation on Windows has been improved.
+
+ * Add missing documentation for "include" and "includeIf" features in
+ "git config" file format, which incidentally teaches the command
+ line completion to include them in its offerings.
+
+ * Avoid "white/black-list" in documentation and code comments.
+
+ * Workaround for a compiler warning against use of die() in
+ osx-keychain (in contrib/).
+
+ * Workaround for a false positive compiler warning.
+
+ * "git p4" working on UTF-16 files on Windows did not implement
+ CRLF-to-LF conversion correctly, which has been corrected.
- (merge d205483695 kk/p4-client-name-encoding-fix later to maint).
+
+ * "git p4" did not handle non-ASCII client name well, which has been
+ corrected.
- (merge cc391fc886 cl/rerere-train-with-no-sign later to maint).
+
+ * "rerere-train" script (in contrib/) used to honor commit.gpgSign
+ while recreating the throw-away merges.
- (merge 611c7785e8 mt/checkout-count-fix later to maint).
+
+ * "git checkout" miscounted the paths it updated, which has been
+ corrected.
- (merge 4447d4129d tk/untracked-cache-with-uall later to maint).
+
+ * Fix for a bug that makes write-tree to fail to write out a
+ non-existent index as a tree, introduced in 2.37.
- (merge 9550f6c16a tb/commit-graph-genv2-upgrade-fix later to maint).
+
+ * There was a bug in the codepath to upgrade generation information
+ in commit-graph from v1 to v2 format, which has been corrected.
- (merge a700395eaf ma/t4200-update later to maint).

- (merge 1e11fab59c jc/string-list-cleanup later to maint).
+
+ * Gitweb had legacy URL shortener that is specific to the way
+ projects hosted on kernel.org used to (but no longer) work, which
+ has been removed.

+ (merge 82ba1191ff js/lstat-mingw-enotdir-fix later to maint).
+
+ * Older gcc with -Wall complains about the universal zero initializer
+ "struct s = { 0 };" idiom, which makes developers' lives
+ inconvenient (as -Werror is enabled by DEVELOPER=YesPlease). The
+ build procedure has been tweaked to help these compilers.
+ (merge b53a5f2416 jk/struct-zero-init-with-older-gcc later to maint).
+
+ * Plug memory leaks in the failure code path in the "merge-ort" merge
+ strategy backend.
