+Git 2.36 Release Notes
+======================
+
+Updates since Git 2.35
+----------------------
+
+Backward compatibility warts
+
+ * "git name-rev --stdin" has been deprecated and issues a warning
+ when used; use "git name-rev --annotate-stdin" instead.
+
+ * "git clone --filter=... --recurse-submodules" only makes the
+ top-level a partial clone, while submodules are fully cloned. This
+ behaviour is changed to pass the same filter down to the submodules.
+
+ * With the fixes for CVE-2022-24765 that are common with versions of
+ Git 2.30.4, 2.31.3, 2.32.2, 2.33.3, 2.34.3, and 2.35.3, Git has
+ been taught not to recognise repositories owned by other users, in
+ order to avoid getting affected by their config files and hooks.
+ You can list the path to the safe/trusted repositories that may be
+ owned by others on a multi-valued configuration variable
+ `safe.directory` to override this behaviour, or use '*' to declare
+ that you trust anything.
+
+
+Note to those who build from the source
+
+ * Since Git 2.31, our source assumed that the compiler you use to
+ build Git supports variadic macros, with an easy-to-use escape
+ hatch to allow compilation without variadic macros with an request
+ to report that you had to use the escape hatch to the list.
+ Because we haven't heard from anybody who actually needed to use
+ the escape hatch, it has been removed, making support of variadic
+ macros a hard requirement.
+
+
+UI, Workflows & Features
+
+ * Assorted updates to "git cat-file", especially "-h".
+
+ * The command line completion (in contrib/) learns to complete
+ arguments to give to "git sparse-checkout" command.
+
+ * "git log --remerge-diff" shows the difference from mechanical merge
+ result and the result that is actually recorded in a merge commit.
+
+ * "git log" and friends learned an option --exclude-first-parent-only
+ to propagate UNINTERESTING bit down only along the first-parent
+ chain, just like --first-parent option shows commits that lack the
+ UNINTERESTING bit only along the first-parent chain.
+
+ * The command line completion script (in contrib/) learned to
+ complete all Git subcommands, including the ones that are normally
+ hidden, when GIT_COMPLETION_SHOW_ALL_COMMANDS is used.
+
+ * "git branch" learned the "--recurse-submodules" option.
+
+ * A user can forget to make a script file executable before giving
+ it to "git bisect run". In such a case, all tests will exit with
+ 126 or 127 error codes, even on revisions that are marked as good.
+ Try to recognize this situation and stop iteration early.
+
+ * When "index-pack" dies due to incoming data exceeding the maximum
+ allowed input size, include the value of the limit in the error
+ message.
+
+ * The error message given by "git switch HEAD~4" has been clarified
+ to suggest the "--detach" option that is required.
+
+ * In sparse-checkouts, files mis-marked as missing from the working tree
+ could lead to later problems. Such files were hard to discover, and
+ harder to correct. Automatically detecting and correcting the marking
+ of such files has been added to avoid these problems.
+
+ * "git cat-file" learns "--batch-command" mode, which is a more
+ flexible interface than the existing "--batch" or "--batch-check"
+ modes, to allow different kinds of inquiries made.
+
+ * The level of verbose output from the ort backend during inner merge
+ has been aligned to that of the recursive backend.
+
+ * "git remote rename A B", depending on the number of remote-tracking
+ refs involved, takes long time renaming them. The command has been
+ taught to show progress bar while making the user wait.
+
+ * Bundle file format gets extended to allow a partial bundle,
+ filtered by similar criteria you would give when making a
+ partial/lazy clone.
+
+ * A new built-in userdiff driver for kotlin has been added.
+
+ * "git repack" learned a new configuration to disable triggering of
+ age-old "update-server-info" command, which is rarely useful these
+ days.
+
+ * "git stash" does not allow subcommands it internally runs as its
+ implementation detail, except for "git reset", to emit messages;
+ now "git reset" part has also been squelched.
+
+ * "git ls-tree" learns "--oid-only" option, similar to "--name-only",
+ and more generalized "--format" option.
+
+ * "git fetch --refetch" learned to fetch everything without telling
+ the other side what we already have, which is useful when you
+ cannot trust what you have in the local object store.
+
+ * "git branch" gives hint when branch tracking cannot be established
+ because fetch refspecs from multiple remote repositories overlap.
+
+ * "git worktree list --porcelain" did not c-quote pathnames and lock
+ reasons with unsafe bytes correctly, which is worked around by
+ introducing NUL terminated output format with "-z".
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "git apply" (ab)used the util pointer of the string-list to keep
+ track of how each symbolic link needs to be handled, which has been
+ simplified by using strset.
+
+ * Fix a hand-rolled alloca() imitation that may have violated
+ alignment requirement of data being sorted in compatibility
+ implementation of qsort_s() and stable qsort().
+
+ * Use the parse-options API in "git reflog" command.
+
+ * The conditional inclusion mechanism of configuration files using
+ "[includeIf <condition>]" learns to base its decision on the
+ URL of the remote repository the repository interacts with.
+ (merge 399b198489 jt/conditional-config-on-remote-url later to maint).
+
+ * "git name-rev --stdin" does not behave like usual "--stdin" at
+ all. Start the process of renaming it to "--annotate-stdin".
+ (merge a2585719b3 jc/name-rev-stdin later to maint).
+
+ * "git update-index", "git checkout-index", and "git clean" are
+ taught to work better with the sparse checkout feature.
+
+ * Use an internal call to reset_head() helper function instead of
+ spawning "git checkout" in "rebase", and update code paths that are
+ involved in the change.
+
+ * Messages "ort" merge backend prepares while dealing with conflicted
+ paths were unnecessarily confusing since it did not differentiate
+ inner merges and outer merges.
+
+ * Small modernization of the rerere-train script (in contrib/).
+
+ * Use designated initializers we started using in mid 2017 in more
+ parts of the codebase that are relatively quiescent.
+
+ * Improve failure case behaviour of xdiff library when memory
+ allocation fails.
+
+ * General clean-up in reftable implementation, including
+ clarification of the API documentation, tightening the code to
+ honor documented length limit, etc.
+
+ * Remove the escape hatch we added when we introduced the weather
+ balloon to use variadic macros unconditionally, to make it official
+ that we now have a hard dependency on the feature.
+
+ * Makefile refactoring with a bit of suffixes rule stripping to
+ optimize the runtime overhead.
+
+ * "git stash drop" is reimplemented as an internal call to
+ reflog_delete() function, instead of invoking "git reflog delete"
+ via run_command() API.
+
+ * Count string_list items in size_t, not "unsigned int".
+
+ * The single-key interactive operation used by "git add -p" has been
+ made more robust.
+
+ * Remove unneeded <meta http-equiv=content-type...> from gitweb
+ output.
+
+ * "git name-rev" learned to use the generation numbers when setting
+ the lower bound of searching commits used to explain the revision,
+ when available, instead of committer time.
+
+ * Replace core.fsyncObjectFiles with two new configuration variables,
+ core.fsync and core.fsyncMethod.
+
+ * Updates to refs traditionally weren't fsync'ed, but we can
+ configure using core.fsync variable to do so.
+
+ * "git reflog" command now uses parse-options API to parse its
+ command line options.
+
+
+Fixes since v2.35
+-----------------
+
+ * "rebase" and "stash" in secondary worktrees are broken in
+ Git 2.35.0, which has been corrected.
+
+ * "git pull --rebase" ignored the rebase.autostash configuration
+ variable when the remote history is a descendant of our history,
+ which has been corrected.
+ (merge 3013d98d7a pb/pull-rebase-autostash-fix later to maint).
+
+ * "git update-index --refresh" has been taught to deal better with
+ racy timestamps (just like "git status" already does).
+ (merge 2ede073fd2 ms/update-index-racy later to maint).
+
+ * Avoid tests that are run under GIT_TRACE2 set from failing
+ unnecessarily.
+ (merge 944d808e42 js/test-unset-trace2-parents later to maint).
+
+ * The merge-ort misbehaved when merge.renameLimit configuration is
+ set too low and failed to find all renames.
+ (merge 9ae39fef7f en/merge-ort-restart-optim-fix later to maint).
+
+ * We explain that revs come first before the pathspec among command
+ line arguments, but did not spell out that dashed options come
+ before other args, which has been corrected.
+ (merge c11f95010c tl/doc-cli-options-first later to maint).
+
+ * "git add -p" rewritten in C regressed hunk splitting in some cases,
+ which has been corrected.
+ (merge 7008ddc645 pw/add-p-hunk-split-fix later to maint).
+
+ * "git fetch --negotiate-only" is an internal command used by "git
+ push" to figure out which part of our history is missing from the
+ other side. It should never recurse into submodules even when
+ fetch.recursesubmodules configuration variable is set, nor it
+ should trigger "gc". The code has been tightened up to ensure it
+ only does common ancestry discovery and nothing else.
+ (merge de4eaae63a gc/fetch-negotiate-only-early-return later to maint).
+
+ * The code path that verifies signatures made with ssh were made to
+ work better on a system with CRLF line endings.
+ (merge caeef01ea7 fs/ssh-signing-crlf later to maint).
+
+ * "git sparse-checkout init" failed to write into $GIT_DIR/info
+ directory when the repository was created without one, which has
+ been corrected to auto-create it.
+ (merge 7f44842ac1 jt/sparse-checkout-leading-dir-fix later to maint).
+
+ * Cloning from a repository that does not yet have any branches or
+ tags but has other refs resulted in a "remote transport reported
+ error", which has been corrected.
+ (merge dccea605b6 jt/clone-not-quite-empty later to maint).
+
+ * Mark in various places in the code that the sparse index and the
+ split index features are mutually incompatible.
+ (merge 451b66c533 js/sparse-vs-split-index later to maint).
+
+ * Update the logic to compute alignment requirement for our mem-pool.
+ (merge e38bcc66d8 jc/mem-pool-alignment later to maint).
+
+ * Pick a better random number generator and use it when we prepare
+ temporary filenames.
+ (merge 47efda967c bc/csprng-mktemps later to maint).
+
+ * Update the contributor-facing documents on proposed log messages.
+ (merge cdba0295b0 jc/doc-log-messages later to maint).
+
+ * When "git fetch --prune" failed to prune the refs it wanted to
+ prune, the command issued error messages but exited with exit
+ status 0, which has been corrected.
+ (merge c9e04d905e tg/fetch-prune-exit-code-fix later to maint).
+
+ * Problems identified by Coverity in the reftable code have been
+ corrected.
+ (merge 01033de49f hn/reftable-coverity-fixes later to maint).
+
+ * A bug that made multi-pack bitmap and the object order out-of-sync,
+ making the .midx data corrupt, has been fixed.
+ (merge f8b60cf99b tb/midx-bitmap-corruption-fix later to maint).
+
+ * The build procedure has been taught to notice older version of zlib
+ and enable our replacement uncompress2() automatically.
+ (merge 07564773c2 ab/auto-detect-zlib-compress2 later to maint).
+
+ * Interaction between fetch.negotiationAlgorithm and
+ feature.experimental configuration variables has been corrected.
+ (merge 714edc620c en/fetch-negotiation-default-fix later to maint).
+
+ * "git diff --diff-filter=aR" is now parsed correctly.
+ (merge 75408ca949 js/diff-filter-negation-fix later to maint).
+
+ * When "git subtree" wants to create a merge, it used "git merge" and
+ let it be affected by end-user's "merge.ff" configuration, which
+ has been corrected.
+ (merge 9158a3564a tk/subtree-merge-not-ff-only later to maint).
+
+ * Unlike "git apply", "git patch-id" did not handle patches with
+ hunks that has only 1 line in either preimage or postimage, which
+ has been corrected.
+ (merge 757e75c81e jz/patch-id-hunk-header-parsing-fix later to maint).
+
+ * "receive-pack" checks if it will do any ref updates (various
+ conditions could reject a push) before received objects are taken
+ out of the temporary directory used for quarantine purposes, so
+ that a push that is known-to-fail will not leave crufts that a
+ future "gc" needs to clean up.
+ (merge 5407764069 cb/clear-quarantine-early-on-all-ref-update-errors later to maint).
+
+ * When there is no object to write .bitmap file for, "git
+ multi-pack-index" triggered an error, instead of just skipping,
+ which has been corrected.
+ (merge eb57277ba3 tb/midx-no-bitmap-for-no-objects later to maint).
+
+ * "git cmd -h" outside a repository should error out cleanly for many
+ commands, but instead it hit a BUG(), which has been corrected.
+ (merge 87ad07d735 js/short-help-outside-repo-fix later to maint).
+
+ * "working tree" and "per-worktree ref" were in glossary, but
+ "worktree" itself wasn't, which has been corrected.
+ (merge 2df5387ed0 jc/glossary-worktree later to maint).
+
+ * L10n support for a few error messages.
+ (merge 3d3c23b3a7 bs/forbid-i18n-of-protocol-token-in-fetch-pack later to maint).
+
+ * Test modernization.
+ (merge d4fe066e4b sy/t0001-use-path-is-helper later to maint).
+
+ * "git log --graph --graph" used to leak a graph structure, and there
+ was no way to countermand "--graph" that appear earlier on the
+ command line. A "--no-graph" option has been added and resource
+ leakage has been plugged.
+
+ * Error output given in response to an ambiguous object name has been
+ improved.
+ (merge 3a73c1dfaf ab/ambiguous-object-name later to maint).
+
+ * "git sparse-checkout" wants to work with per-worktree configuration,
+ but did not work well in a worktree attached to a bare repository.
+ (merge 3ce1138272 ds/sparse-checkout-requires-per-worktree-config later to maint).
+
+ * Setting core.untrackedCache to true failed to add the untracked
+ cache extension to the index.
+
+ * Workaround we have for versions of PCRE2 before their version 10.36
+ were in effect only for their versions newer than 10.36 by mistake,
+ which has been corrected.
+ (merge 97169fc361 rs/pcre-invalid-utf8-fix-fix later to maint).
+
+ * Document Taylor as a new member of Git PLC at SFC. Welcome.
+ (merge e8d56ca863 tb/coc-plc-update later to maint).
+
+ * "git checkout -b branch/with/multi/level/name && git stash" only
+ recorded the last level component of the branch name, which has
+ been corrected.
+
+ * Check the return value from parse_tree_indirect() to turn segfaults
+ into calls to die().
+ (merge 8d2eaf649a gc/parse-tree-indirect-errors later to maint).
+
+ * Newer version of GPGSM changed its output in a backward
+ incompatible way to break our code that parses its output. It also
+ added more processes our tests need to kill when cleaning up.
+ Adjustments have been made to accommodate these changes.
+ (merge b0b70d54c4 fs/gpgsm-update later to maint).
+
+ * The untracked cache newly computed weren't written back to the
+ on-disk index file when there is no other change to the index,

+
+ * "git config -h" did not describe the "--type" option correctly.
+ (merge 5445124fad mf/fix-type-in-config-h later to maint).

+ * The way generation number v2 in the commit-graph files are
+ (not) handled has been corrected.

+
+ * The method to trigger malloc check used in our tests no longer work
+ with newer versions of glibc.
+ (merge baedc59543 ep/test-malloc-check-with-glibc-2.34 later to maint).
+
+ * When "git fetch --recurse-submodules" grabbed submodule commits
+ that would be needed to recursively check out newly fetched commits
+ in the superproject, it only paid attention to submodules that are
+ in the current checkout of the superproject. We now do so for all
+ submodules that have been run "git submodule init" on.
+
+ * "git rebase $base $non_branch_commit", when $base is an ancestor or
+ the $non_branch_commit, modified the current branch, which has been
+ corrected.
+
+ * When "shallow" information is updated, we forgot to update the
+ in-core equivalent, which has been corrected.
+
+ * When creating a loose object file, we didn't report the exact
+ filename of the file we failed to fsync, even though the
+ information was readily available, which has been corrected.
+
+ * "git am" can read from the standard input when no mailbox is given
+ on the command line, but the end-user gets no indication when it
+ happens, making Git appear stuck.
+ (merge 7b20af6a06 jc/mailsplit-warn-on-tty later to maint).

+=========================
+
+Fixes since v2.36
+-----------------
+
+ * "git submodule update" without pathspec should silently skip an
+ uninitialized submodule, but it started to become noisy by mistake.
+
+ * "diff-tree --stdin" has been broken for about a year, but 2.36
+ release broke it even worse by breaking running the command with
+ <pathspec>, which in turn broke "gitk" and got noticed. This has
+ been corrected by aligning its behaviour to that of "log".
+
+ * Regression fix for 2.36 where "git name-rev" started to sometimes
+ reference strings after they are freed.
+
+ * "git show <commit1> <commit2>... -- <pathspec>" lost the pathspec
+ when showing the second and subsequent commits, which has been
+ corrected.
+
+ * "git fast-export -- <pathspec>" lost the pathspec when showing the
+ second and subsequent commits, which has been corrected.
+
+ * "git format-patch <args> -- <pathspec>" lost the pathspec when
+ showing the second and subsequent commits, which has been
+ corrected.
+
+ * Get rid of a bogus and over-eager coccinelle rule.
+
+ * Correct choices of C compilers used in various CI jobs.
+
+Also contains minor documentation updates and code clean-ups.

+Git v2.37 Release Notes
+=======================
+
+UI, Workflows & Features
+
+ * "vimdiff[123]" mergetool drivers have been reimplemented with a
+ more generic layout mechanism.
+
+ * "git -v" and "git -h" are now understood as "git --version" and
+ "git --help".
+
+ * The temporary files fed to external diff command are now generated
+ inside a new temporary directory under the same basename.
+
+ * "git log --since=X" will stop traversal upon seeing a commit that
+ is older than X, but there may be commits behind it that is younger
+ than X when the commit was created with a faulty clock. A new
+ option is added to keep digging without stopping, and instead
+ filter out commits with timestamp older than X.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The performance of the "untracked cache" feature has been improved
+ when "--untracked-files=<mode>" and "status.showUntrackedFiles"
+ are combined.
+
+ * "git stash" works better with sparse index entries.
+
+ * "git show :<path>" learned to work better with the sparse-index
+ feature.
+
+ * Introduce and apply coccinelle rule to discourage an explicit
+ comparison between a pointer and NULL, and applies the clean-up to
+ the maintenance track.

----
-Using --recurse-submodules can only fetch new commits in already checked
-out submodules right now. When e.g. upstream added a new submodule in the
-just fetched commits of the superproject the submodule itself cannot be
-fetched, making it impossible to check out that submodule later without
-having to do a fetch again. This is expected to be fixed in a future Git
-version.
+Using --recurse-submodules can only fetch new commits in submodules that are
+present locally e.g. in `$GIT_DIR/modules/`. If the upstream adds a new
+submodule, that submodule cannot be fetched until it is cloned e.g. by `git

+NAME
+----
+git-fsmonitor--daemon - A Built-in File System Monitor
+
+SYNOPSIS
+--------
+[verse]
+'git fsmonitor{litdd}daemon' start
+'git fsmonitor{litdd}daemon' run
+'git fsmonitor{litdd}daemon' stop
+'git fsmonitor{litdd}daemon' status
+
+DESCRIPTION
+-----------
+
+A daemon to watch the working directory for file and directory
+changes using platform-specific file system notification facilities.
+
+This daemon communicates directly with commands like `git status`
+using the link:technical/api-simple-ipc.html[simple IPC] interface
+instead of the slower linkgit:githooks[5] interface.
+
+This daemon is built into Git so that no third-party tools are
+required.
+
+OPTIONS
+-------
+
+start::
+ Starts a daemon in the background.
+
+run::
+ Runs a daemon in the foreground.
+
+stop::
+ Stops the daemon running in the current working
+ directory, if present.
+
+status::
+ Exits with zero status if a daemon is watching the
+ current working directory.
+
+REMARKS
+-------
+
+This daemon is a long running process used to watch a single working
+directory and maintain a list of the recently changed files and
+directories. Performance of commands such as `git status` can be
+increased if they just ask for a summary of changes to the working
+directory and can avoid scanning the disk.
+
+When `core.fsmonitor` is set to `true` (see linkgit:git-config[1])
+commands, such as `git status`, will ask the daemon for changes and
+automatically start it (if necessary).
+
+For more information see the "File System Monitor" section in
+linkgit:git-update-index[1].
+
+CAVEATS
+-------
+
+The fsmonitor daemon does not currently know about submodules and does
+not know to filter out file system events that happen within a
+submodule. If fsmonitor daemon is watching a super repo and a file is
+modified within the working directory of a submodule, it will report
+the change (as happening against the super repo). However, the client
+will properly ignore these extra events, so performance may be affected
+but it will not cause an incorrect result.

DESCRIPTION
-----------
-Initialize and modify the sparse-checkout configuration, which reduces
-the checkout to a set of paths given by a list of patterns.
+This command is used to create sparse checkouts, which means that it
+changes the working tree from having all tracked files present, to only
+have a subset of them. It can also switch which subset of files are
+present, or undo and go back to having all tracked files present in the
+working copy.
+
+The subset of files is chosen by providing a list of directories in
+cone mode (which is recommended), or by providing a list of patterns
+in non-cone mode.
+
+When in a sparse-checkout, other Git commands behave a bit differently.
+For example, switching branches will not update paths outside the
+sparse-checkout directories/patterns, and `git commit -a` will not record
+paths outside the sparse-checkout directories/patterns as deleted.

SKIP-WORKTREE BIT
-----------------
-Skip-worktree bit can be defined in one (long) sentence: When reading
-an entry, if it is marked as skip-worktree, then Git pretends its
-working directory version is up to date and read the index version
-instead.
-
-To elaborate, "reading" means checking for file existence, reading
-file attributes or file content. The working directory version may be
-present or absent. If present, its content may match against the index
-version or not. Writing is not affected by this bit, content safety
-is still first priority. Note that Git _can_ update working directory
-file, that is marked skip-worktree, if it is safe to do so (i.e.
-working directory version matches index version)
+Skip-worktree bit can be defined in one (long) sentence: Tell git to
+avoid writing the file to the working directory when reasonably
+possible, and treat the file as unchanged when it is not
+present in the working directory.
+
+Note that not all git commands will pay attention to this bit, and
+some only partially support it.
+
+The update-index flags and the read-tree capabilities relating to the
+skip-worktree bit predated the introduction of the
+linkgit:git-sparse-checkout[1] command, which provides a much easier
+way to configure and handle the skip-worktree bits. If you want to
+reduce your working tree to only deal with a subset of the files in
+the repository, we strongly encourage the use of
+linkgit:git-sparse-checkout[1] in preference to the low-level
+update-index and read-tree primitives.
+
+The primary purpose of the skip-worktree bit is to enable sparse
+checkouts, i.e. to have working directories with only a subset of
+paths present. When the skip-worktree bit is set, Git commands (such
+as `switch`, `pull`, `merge`) will avoid writing these files.
+However, these commands will sometimes write these files anyway in
+important cases such as conflicts during a merge or rebase. Git
+commands will also avoid treating the lack of such files as an
+intentional deletion; for example `git add -u` will not not stage a
+deletion for these files and `git commit -a` will not make a commit
+deleting them either.
Although this bit looks similar to assume-unchanged bit, its goal is
-different from assume-unchanged bit's. Skip-worktree also takes
-precedence over assume-unchanged bit when both are set.
+different. The assume-unchanged bit is for leaving the file in the
+working tree but having Git omit checking it for changes and presuming
+that the file has not been changed (though if it can determine without
+stat'ing the file that it has changed, it is free to record the
+changes). skip-worktree tells Git to ignore the absence of the file,
+avoid updating it when possible with commands that normally update
+much of the working directory (e.g. `checkout`, `switch`, `pull`,
+etc.), and not have its absence be recorded in commits. Note that in
+sparse checkouts (setup by `git sparse-checkout` or by configuring
+core.sparseCheckout to true), if a file is marked as skip-worktree in
+the index but is found in the working tree, Git will clear the

In its simplest form, `git worktree add <path>` automatically creates a
new branch whose name is the final component of `<path>`, which is
convenient if you plan to work on a new topic. For instance, `git
worktree add ../hotfix` creates new branch `hotfix` and checks it out at

+Description
+^^^^^^^^^^^
+
+When specifying `--tool=vimdiff` in `git mergetool` Git will open Vim with a 4
+windows layout distributed in the following way:
+....
+------------------------------------------
+| | | |
+| LOCAL | BASE | REMOTE |
+| | | |
+------------------------------------------
+| |
+| MERGED |
+| |
+------------------------------------------
+....
+`LOCAL`, `BASE` and `REMOTE` are read-only buffers showing the contents of the
+conflicting file in specific commits ("commit you are merging into", "common
+ancestor commit" and "commit you are merging from" respectively)
+
+`MERGED` is a writable buffer where you have to resolve the conflicts (using the
+other read-only buffers as a reference). Once you are done, save and exit Vim as
+usual (`:wq`) or, if you want to abort, exit using `:cq`.
+
+Layout configuration
+^^^^^^^^^^^^^^^^^^^^
+
+You can change the windows layout used by Vim by setting configuration variable
+`mergetool.vimdiff.layout` which accepts a string where the following separators
+have special meaning:
+
+ - `+` is used to "open a new tab"
+ - `,` is used to "open a new vertical split"
+ - `/` is used to "open a new horizontal split"
+ - `@` is used to indicate which is the file containing the final version after
+ solving the conflicts. If not present, `MERGED` will be used by default.
+
+The precedence of the operators is this one (you can use parentheses to change
+it):
+
+ `@` > `+` > `/` > `,`
+
+Let's see some examples to understand how it works:
+
+* `layout = "(LOCAL,BASE,REMOTE)/MERGED"`
++
+--
+This is exactly the same as the default layout we have already seen.
+
+Note that `/` has precedence over `,` and thus the parenthesis are not
+needed in this case. The next layout definition is equivalent:
+
+ layout = "LOCAL,BASE,REMOTE / MERGED"
+--
+* `layout = "LOCAL,MERGED,REMOTE"`
++
+--
+If, for some reason, we are not interested in the `BASE` buffer.
+....
+------------------------------------------
+| | | |
+| | | |
+| LOCAL | MERGED | REMOTE |
+| | | |
+| | | |
+------------------------------------------
+....
+--
+* `layout = "MERGED"`
++
+--
+Only the `MERGED` buffer will be shown. Note, however, that all the other
+ones are still loaded in vim, and you can access them with the "buffers"
+command.
+....
+------------------------------------------
+| |
+| |
+| MERGED |
+| |
+| |
+------------------------------------------
+....
+--
+* `layout = "@LOCAL,REMOTE"`
++
+--
+When `MERGED` is not present in the layout, you must "mark" one of the
+buffers with an asterisk. That will become the buffer you need to edit and
+save after resolving the conflicts.
+....
+------------------------------------------
+| | |
+| | |
+| | |
+| LOCAL | REMOTE |
+| | |
+| | |
+| | |
+------------------------------------------
+....
+--
+* `layout = "LOCAL,BASE,REMOTE / MERGED + BASE,LOCAL + BASE,REMOTE"`
++
+--
+Three tabs will open: the first one is a copy of the default layout, while
+the other two only show the differences between (`BASE` and `LOCAL`) and
+(`BASE` and `REMOTE`) respectively.
+....
+------------------------------------------
+| <TAB #1> | TAB #2 | TAB #3 | |
+------------------------------------------
+| | | |
+| LOCAL | BASE | REMOTE |

+* `layout = "LOCAL,BASE,REMOTE / MERGED + BASE,LOCAL + BASE,REMOTE + (LOCAL/BASE/REMOTE),MERGED"`
++
+--
+Same as the previous example, but adds a fourth tab with the same
+information as the first tab, with a different layout.

+---------------------------------------------
+| LOCAL | |
+|---------------------| |
+| BASE | MERGED |
+|---------------------| |
+| REMOTE | |
+---------------------------------------------
+....
+Note how in the third tab definition we need to use parenthesis to make `,`
+have precedence over `/`.
+--
+
+Variants
+^^^^^^^^
+
+Instead of `--tool=vimdiff`, you can also use one of these other variants:
+
+ * `--tool=gvimdiff`, to open gVim instead of Vim.
+
+ * `--tool=nvimdiff`, to open Neovim instead of Vim.
+
+When using these variants, in order to specify a custom layout you will have to
+set configuration variables `mergetool.gvimdiff.layout` and
+`mergetool.nvimdiff.layout` instead of `mergetool.vimdiff.layout`
+
+In addition, for backwards compatibility with previous Git versions, you can
+also append `1`, `2` or `3` to either `vimdiff` or any of the variants (ex:
+`vimdiff3`, `nvimdiff1`, etc...) to use a predefined layout.
+In other words, using `--tool=[g,n,]vimdiffx` is the same as using
+`--tool=[g,n,]vimdiff` and setting configuration variable
+`mergetool.[g,n,]vimdiff.layout` to...
+
+ * `x=1`: `"@LOCAL, REMOTE"`
+ * `x=2`: `"LOCAL, MERGED, REMOTE"`
+ * `x=3`: `"MERGED"`
+
+Example: using `--tool=gvimdiff2` will open `gvim` with three columns (LOCAL,
+MERGED and REMOTE).

+ * Requests to and from a FSMonitor Protocol V2 provider use an opaque
+ * "token" as a virtual timestamp. Clients can request a summary of all
+ * created/deleted/modified files relative to a token. In the response,
+ * clients receive a new token for the next (relative) request.
+ *
+ *
+ * Token Format
+ * ============
+ *
+ * The contents of the token are private and provider-specific.
+ *
+ * For the built-in fsmonitor--daemon, we define a token as follows:
+ *
+ * "builtin" ":" <token_id> ":" <sequence_nr>
+ *
+ * The "builtin" prefix is used as a namespace to avoid conflicts
+ * with other providers (such as Watchman).
+ *
+ * The <token_id> is an arbitrary OPAQUE string, such as a GUID,
+ * UUID, or {timestamp,pid}. It is used to group all filesystem
+ * events that happened while the daemon was monitoring (and in-sync
+ * with the filesystem).
+ *
+ * Unlike FSMonitor Protocol V1, it is not defined as a timestamp
+ * and does not define less-than/greater-than relationships.
+ * (There are too many race conditions to rely on file system
+ * event timestamps.)
+ *
+ * The <sequence_nr> is a simple integer incremented whenever the
+ * daemon needs to make its state public. For example, if 1000 file
+ * system events come in, but no clients have requested the data,
+ * the daemon can continue to accumulate file changes in the same
+ * bin and does not need to advance the sequence number. However,
+ * as soon as a client does arrive, the daemon needs to start a new
+ * bin and increment the sequence number.
+ *
+ * The sequence number serves as the boundary between 2 sets
+ * of bins -- the older ones that the client has already seen
+ * and the newer ones that it hasn't.
+ *
+ * When a new <token_id> is created, the <sequence_nr> is reset to
+ * zero.
+ *
+ *
+ * About Token Ids
+ * ===============
+ *
+ * A new token_id is created:
+ *
+ * [1] each time the daemon is started.
+ *
+ * [2] any time that the daemon must re-sync with the filesystem
+ * (such as when the kernel drops or we miss events on a very
+ * active volume).
+ *
+ * [3] in response to a client "flush" command (for dropped event
+ * testing).
+ *
+ * When a new token_id is created, the daemon is free to discard all
+ * cached filesystem events associated with any previous token_ids.
+ * Events associated with a non-current token_id will never be sent
+ * to a client. A token_id change implicitly means that the daemon
+ * has gap in its event history.
+ *
+ * Therefore, clients that present a token with a stale (non-current)
+ * token_id will always be given a trivial response.
