+Git 2.34 Release Notes
+======================
+
+Updates since Git 2.33
+----------------------
+
+UI, Workflows & Features
+
+ * Pathname expansion (like "~username/") learned a way to specify a
+ location relative to Git installation (e.g. its $sharedir which is
+ $(prefix)/share), with "%(prefix)".
+
+ * Use `ort` instead of `recursive` as the default merge strategy.
+
+ * The userdiff pattern for "java" language has been updated.
+
+ * "git rebase" by default skips changes that are equivalent to
+ commits that are already in the history the branch is rebased onto;
+ give messages when this happens to let the users be aware of
+ skipped commits, and also teach them how to tell "rebase" to keep
+ duplicated changes.
+
+ * The advice message that "git cherry-pick" gives when it asks
+ conflicted replay of a commit to be resolved by the end user has
+ been updated.
+
+ * After "git clone --recurse-submodules", all submodules are cloned
+ but they are not by default recursed into by other commands. With
+ submodule.stickyRecursiveClone configuration set, submodule.recurse
+ configuration is set to true in a repository created by "clone"
+ with "--recurse-submodules" option.
+
+ * The logic for auto-correction of misspelt subcommands learned to go
+ interactive when the help.autocorrect configuration variable is set
+ to 'prompt'.
+
+ * "git maintenance" scheduler learned to use systemd timers as a
+ possible backend.
+
+ * "git diff --submodule=diff" showed failure from run_command() when
+ trying to run diff inside a submodule, when the user manually
+ removes the submodule directory.
+
+ * "git bundle unbundle" learned to show progress display.
+
+ * In cone mode, the sparse-index code path learned to remove ignored
+ files (like build artifacts) outside the sparse cone, allowing the
+ entire directory outside the sparse cone to be removed, which is
+ especially useful when the sparse patterns change.
+
+ * Taking advantage of the CGI interface, http-backend has been
+ updated to enable protocol v2 automatically when the other side
+ asks for it.
+
+ * The credential-cache helper has been adjusted to Windows.
+
+ * The error in "git help no-such-git-command" is handled better.
+
+ * The unicode character width table (used for output alignment) has
+ been updated.
+
+ * The ref iteration code used to optionally allow dangling refs to be
+ shown, which has been tightened up.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "git bisect" spawned "git show-branch" only to pretty-print the
+ title of the commit after checking out the next version to be
+ tested; this has been rewritten in C.
+
+ * "git add" can work better with the sparse index.
+
+ * Support for ancient versions of cURL library (pre 7.19.4) has been
+ dropped.
+
+ * A handful of tests that assumed implementation details of files
+ backend for refs have been cleaned up.
+
+ * trace2 logs learned to show parent process name to see in what
+ context Git was invoked.
+
+ * Loading of ref tips to prepare for common ancestry negotiation in
+ "git fetch-pack" has been optimized by taking advantage of the
+ commit graph when available.
+
+ * Remind developers that the userdiff patterns should be kept simple
+ and permissive, assuming that the contents they apply are always
+ syntactically correct.
+
+ * The current implementation of GIT_TEST_FAIL_PREREQS is broken in
+ that checking for the lack of a prerequisite would not work. Avoid
+ the use of "if ! test_have_prereq X" in a test script.
+
+ * The revision traversal API has been optimized by taking advantage
+ of the commit-graph, when available, to determine if a commit is
+ reachable from any of the existing refs.
+
+ * "git fetch --quiet" optimization to avoid useless computation of
+ info that will never be displayed.
+
+ * Callers from older advice_config[] based API has been updated to
+ use the newer advice_if_enabled() and advice_enabled() API.
+
+ * Teach "test_pause" and "debug" helpers to allow using the HOME and
+ TERM environment variables the user usually uses.
+
+ * "make INSTALL_STRIP=-s install" allows the installation step to use
+ "install -s" to strip the binaries as they get installed.
+
+ * Code that handles large number of refs in the "git fetch" code
+ path has been optimized.
+
+ * The reachability bitmap file used to be generated only for a single
+ pack, but now we've learned to generate bitmaps for history that
+ span across multiple packfiles.
+
+ * The code to make "git grep" recurse into submodules has been
+ updated to migrate away from the "add submodule's object store as
+ an alternate object store" mechanism (which is suboptimal).
+
+ * The tracing of process ancestry information has been enhanced.
+
+ * Reduce number of write(2) system calls while sending the
+ ref advertisement.
+
+ * Update the build procedure to use the "-pedantic" build when
+ DEVELOPER makefile macro is in effect.
+
+ * Large part of "git submodule add" gets rewritten in C.
+
+ * The run-command API has been updated so that the callers can easily
+ ask the file descriptors open for packfiles to be closed immediately
+ before spawning commands that may trigger auto-gc.
+
+ * An oddball OPTION_ARGUMENT feature has been removed from the
+ parse-options API.
+
+ * The mergesort implementation used to sort linked list has been
+ optimized.
+
+ * Remove external declaration of functions that no longer exist.
+
+ * "git multi-pack-index write --bitmap" learns to propagate the
+ hashcache from original bitmap to resulting bitmap.
+
+ * CI learns to run the leak sanitizer builds.
+
+
+Fixes since v2.33
+-----------------
+
+ * Input validation of "git pack-objects --stdin-packs" has been
+ corrected.
- (merge 82823118b9 jt/push-negotiation-fixes later to maint).
+
+ * Bugfix for common ancestor negotiation recently introduced in "git
+ push" code path.
- (merge 6f843a3355 en/pull-conflicting-options later to maint).
+
+ * "git pull" had various corner cases that were not well thought out
+ around its --rebase backend, e.g. "git pull --ff-only" did not stop
+ but went ahead and rebased when the history on other side is not a
+ descendant of our history. The series tries to fix them up.
- (merge 46d723ce57 jk/apply-binary-hunk-parsing-fix later to maint).
+
+ * "git apply" miscounted the bytes and failed to read to the end of
+ binary hunks.
- (merge c4d5907324 jk/range-diff-fixes later to maint).
+
+ * "git range-diff" code clean-up.
- (merge 8ef6aad664 jk/commit-edit-fixup-fix later to maint).
+
+ * "git commit --fixup" now works with "--edit" again, after it was
+ broken in v2.32.
- (merge 3cf9bb36bf cb/ci-use-upload-artifacts-v1 later to maint).
+
+ * Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the
+ new version has a blocker bug for that architecture.
- (merge e5ee33e855 pw/rebase-skip-final-fix later to maint).
+
+ * Checking out all the paths from HEAD during the last conflicted
+ step in "git rebase" and continuing would cause the step to be
+ skipped (which is expected), but leaves MERGE_MSG file behind in
+ $GIT_DIR and confuses the next "git commit", which has been
+ corrected.
- (merge f2563c9ef3 pw/rebase-r-fixes later to maint).
+
+ * Various bugs in "git rebase -r" have been fixed.
- (merge 95b4ff3931 rs/git-mmap-uses-malloc later to maint).
+
+ * mmap() imitation used to call xmalloc() that dies upon malloc()
+ failure, which has been corrected to just return an error to the
+ caller to be handled.
- (merge 8174627b3d dd/diff-files-unmerged-fix later to maint).
+
+ * "git diff --relative" segfaulted and/or produced incorrect result
+ when there are unmerged paths.
- (merge 7a132c628e mt/quiet-with-delayed-checkout later to maint).
+
+ * The delayed checkout code path in "git checkout" etc. were chatty
+ even when --quiet and/or --no-progress options were given.
- (merge 597a977489 rs/branch-allow-deleting-dangling later to maint).
+
+ * "git branch -D <branch>" used to refuse to remove a broken branch
+ ref that points at a missing commit, which has been corrected.
- (merge f32c5d3716 cb/makefile-apple-clang later to maint).
+
+ * Build update for Apple clang.
- (merge c93ca46cf5 sg/column-nl later to maint).
+
+ * The parser for the "--nl" option of "git column" has been
+ corrected.
- (merge 53a66ec37c ka/want-ref-in-namespace later to maint).
+
+ * "git upload-pack" which runs on the other side of "git fetch"
+ forgot to take the ref namespaces into account when handling
+ want-ref requests.
- (merge d9e9b44d7a jh/sparse-index-resize-fix later to maint).
+
+ * The sparse-index support can corrupt the index structure by storing
+ a stale and/or uninitialized data, which has been corrected.
- (merge 614c3d8f2e sg/set-ceiling-during-tests later to maint).
+
+ * Buggy tests could damage repositories outside the throw-away test
+ area we created. We now by default export GIT_CEILING_DIRECTORIES
+ to limit the damage from such a stray test.
- (merge e082113484 mh/send-email-reset-in-reply-to later to maint).
+
+ * Even when running "git send-email" without its own threaded
+ discussion support, a threading related header in one message is
+ carried over to the subsequent message to result in an unwanted
+ threading, which has been corrected.
- (merge 2f040a9671 tk/fast-export-anonymized-tag-fix later to maint).
+
+ * The output from "git fast-export", when its anonymization feature
+ is in use, showed an annotated tag incorrectly.
- (merge 1e93770888 jk/log-warn-on-bogus-encoding later to maint).
+
+ * Doc update plus improved error reporting.
- (merge 5acffd3473 so/diff-index-regression-fix later to maint).
+
+ * Recent "diff -m" changes broke "gitk", which has been corrected.
- (merge b996f84989 ab/send-email-config-fix later to maint).
+
+ * Regression fix.
- (merge 57f183b698 jc/trivial-threeway-binary-merge later to maint).
+
+ * The "git apply -3" code path learned not to bother the lower level
+ merge machinery when the three-way merge can be trivially resolved
+ without the content level merge. This fixes a regression caused by
+ recent "-3way first and fall back to direct application" change.
- (merge 8fe8bae9d2 ab/reverse-midx-optim later to maint).
+
+ * The code that optionally creates the *.rev reverse index file has
+ been optimized to avoid needless computation when it is not writing
+ the file out.
- (merge 709b3f32d3 rs/range-diff-avoid-segfault-with-I later to maint).
+
+ * "git range-diff -I... <range> <range>" segfaulted, which has been
+ corrected.
- (merge 4bc1fd6e39 tb/pack-finalize-ordering later to maint).
+
+ * The order in which various files that make up a single (conceptual)
+ packfile has been reevaluated and straightened up. This matters in
+ correctness, as an incomplete set of files must not be shown to a
+ running Git.
- (merge 35cf94eaf6 rs/no-mode-to-open-when-appending later to maint).
+
+ * The "mode" word is useless in a call to open(2) that does not
+ create a new file. Such a call in the files backend of the ref
+ subsystem has been cleaned up.
- (merge 7c1200745b ps/update-ref-batch-flush later to maint).
+
+ * "git update-ref --stdin" failed to flush its output as needed,
+ which potentially led the conversation to a deadlock.
- (merge c5ead19ea2 en/am-abort-fix later to maint).
+
+ * When "git am --abort" fails to abort correctly, it still exited
+ with exit status of 0, which has been corrected.
- (merge 8d133a4653 jk/strvec-typefix later to maint).
+
+ * Correct nr and alloc members of strvec struct to be of type size_t.
- (merge bee8691f19 en/stash-df-fix later to maint).
+
+ * "git stash", where the tentative change involves changing a
+ directory to a file (or vice versa), was confused, which has been
+ corrected.
- (merge 6b58df54cf jk/clone-unborn-head-in-bare later to maint).
+
+ * "git clone" from a repository whose HEAD is unborn into a bare
+ repository didn't follow the branch name the other side used, which
+ is corrected.
- (merge 4b81f690f6 cb/cvsserver later to maint).
+
+ * "git cvsserver" had a long-standing bug in its authentication code,
+ which has finally been corrected (it is unclear and is a separate
+ question if anybody is seriously using it, though).
- (merge 5bafb3576a da/difftool-dir-diff-symlink-fix later to maint).
+
+ * "git difftool --dir-diff" mishandled symbolic links.
- (merge b66c77a64e jk/http-redact-fix later to maint).
+
+ * Sensitive data in the HTTP trace were supposed to be redacted, but
+ we failed to do so in HTTP/2 requests.
- (merge f0a74bcb03 ab/make-clean-depend-dirs later to maint).
+
+ * "make clean" has been updated to remove leftover .depend/
+ directories, even when it is not told to use them to compute header
+ dependencies.
- (merge 44d2aec6e8 ah/connect-parse-feature-v0-fix later to maint).
+
+ * Protocol v0 clients can get stuck parsing a malformed feature line.
- (merge 1d9c8daef8 ab/bundle-doc later to maint).
