+Git 2.24 Release Notes
+======================
+
+Updates since v2.23
+-------------------
+
+Backward compatibility note
+
+ * Although it is not officially deprecated, "filter-branch" is
+   showing its age and alternatives are available.  From this release,
+   we started to discourage its uses and hint people about
+   filter-repo.
+
+UI, Workflows & Features
+
+ * We now have an active interim maintainer for the Git-Gui part of
+   the system.  Praise and thank Pratyush Yadav for volunteering.
+
+ * The command line parser learned "--end-of-options" notation; the
+   standard convention for scripters to have hardcoded set of options
+   first on the command line, and force the command to treat end-user
+   input as non-options, has been to use "--" as the delimiter, but
+   that would not work for commands that use "--" as a delimiter
+   between revs and pathspec.
+
+ * A mechanism to affect the default setting for a (related) group of
+   configuration variables is introduced.
+
+ * "git fetch" learned "--set-upstream" option to help those who first
+   clone from their private fork they intend to push to, add the true
+   upstream via "git remote add" and then "git fetch" from it.
+
+ * Device-tree files learned their own userdiff patterns.
+   (merge 3c81760bc6 sb/userdiff-dts later to maint).
+
+ * "git rebase --rebase-merges" learned to drive different merge
+   strategies and pass strategy specific options to them.
+
+ * A new "pre-merge-commit" hook has been introduced.
+
+ * Command line completion updates for "git -c var.name=val" have been
+   added.
+
+ * The lazy clone machinery has been taught that there can be more
+   than one promisor remote and consult them in order when downloading
+   missing objects on demand.
+
+ * The list-objects-filter API (used to create a sparse/lazy clone)
+   learned to take a combined filter specification.
+
+ * The documentation and tests for "git format-patch" have been
+   cleaned up.
+
+ * On Windows, the root level of UNC share is now allowed to be used
+   just like any other directory.
+
+ * The command line completion support (in contrib/) learned about the
+   "--skip" option of "git revert" and "git cherry-pick".
+
+ * "git rebase --keep-base <upstream>" tries to find the original base
+   of the topic being rebased and rebase on top of that same base,
+   which is useful when running the "git rebase -i" (and its limited
+   variant "git rebase -x").
+
+   The command also has learned to fast-forward in more cases where it
+   can instead of replaying to recreate identical commits.
+
+ * A configuration variable tells "git fetch" to write the commit
+   graph after finishing.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The code to write commit-graph over given commit object names has
+   been made a bit more robust.
+
+ * The first line of verbose output from each test piece now carries
+   the test name and number to help scanning with eyeballs.
+
+ * Further clean-up of the initialization code.
+
+ * xmalloc() used to have a mechanism to ditch memory and address
+   space resources as the last resort upon seeing an allocation
+   failure from the underlying malloc(), which made the code complex
+   and thread-unsafe with dubious benefit, as major memory resource
+   users already do limit their uses with various other mechanisms.
+   It has been simplified away.
+
+ * Unnecessary full-tree diff in "git log -L" machinery has been
+   optimized away.
+
+ * The http transport lacked some optimization the native transports
+   learned to avoid unnecessary ref advertisement, which has been
+   corrected.
+
+ * Preparation for SHA-256 upgrade continues in the test department.
+   (merge 0c37c41d13 bc/hash-independent-tests-part-5 later to maint).
+
+ * The memory ownership model of the "git fast-import" got
+   straightened out.
+
+ * Output from trace2 subsystem is formatted more prettily now.
+
+ * The internal code originally invented for ".gitignore" processing
+   got reshuffled and renamed to make it less tied to "excluding" and
+   stress more that it is about "matching", as it has been reused for
+   things like sparse checkout specification that want to check if a
+   path is "included".
+
+
+
+Fixes since v2.23
+-----------------
+
+ * "git grep --recurse-submodules" that looks at the working tree
+   files looked at the contents in the index in submodules, instead of
+   files in the working tree.
+   (merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).
+
+ * Codepaths to walk tree objects have been audited for integer
+   overflows and hardened.
+   (merge 5aa02f9868 jk/tree-walk-overflow later to maint).
+
+ * "git pack-refs" can lose refs that are created while running, which
+   is getting corrected.
+   (merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).
+
+ * "git checkout" and "git restore" to re-populate the index from a
+   tree-ish (typically HEAD) did not work correctly for a path that
+   was removed and then added again with the intent-to-add bit, when
+   the corresponding working tree file was empty.  This has been
+   corrected.
+
+ * Compilation fix.
+   (merge 70597e8386 rs/nedalloc-fixlets later to maint).
+
+ * "git gui" learned to call the clean-up procedure before exiting.
+   (merge 0d88f3d2c5 py/git-gui-do-quit later to maint).
+
+ * We promoted the "indent heuristics" that decides where to split
+   diff hunks from experimental to the default a few years ago, but
+   some stale documentation still marked it as experimental, which has
+   been corrected.
+   (merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).
+
+ * Fix a mismerge that happened in 2.22 timeframe.
+   (merge acb7da05ac en/checkout-mismerge-fix later to maint).
+
+ * "git archive" recorded incorrect length in extended pax header in
+   some corner cases, which has been corrected.
+   (merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).
+
+ * On-demand object fetching in lazy clone incorrectly tried to fetch
+   commits from submodule projects, while still working in the
+   superproject, which has been corrected.
+   (merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).
+
+ * Prepare get_short_oid() codepath to be thread-safe.
+   (merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).
+
+ * "for-each-ref" and friends that show refs did not protect themselves
+   against ancient tags that did not record tagger names when asked to
+   show "%(taggername)", which have been corrected.
+   (merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).
+
+ * The "git am" based backend of "git rebase" ignored the result of
+   updating ".gitattributes" done in one step when replaying
+   subsequent steps.
+   (merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).
+
+ * Tell cURL library to use the same malloc() implementation, with the
+   xmalloc() wrapper, as the rest of the system, for consistency.
+   (merge 93b980e58f cb/curl-use-xmalloc later to maint).
+
+ * Build fix to adjust .gitignore to unignore a path that we started to track.
+   (merge aac6ff7b5b js/visual-studio later to maint).
+
+ * A few implementation fixes in the notes API.
+   (merge 60fe477a0b mh/notes-duplicate-entries later to maint).
+
+ * Fix an earlier regression to "git push --all" which should have
+   been forbidden when the target remote repository is set to be a
+   mirror.
+   (merge 8e4c8af058 tg/push-all-in-mirror-forbidden later to maint).
+
+ * Fix an earlier regression in the test suite, which mistakenly
+   stopped running HTTPD tests.
+   (merge 3960290675 sg/git-test-boolean later to maint).
+
+ * "git rebase --autostash <upstream> <branch>", when <branch> is
+   different from the current branch, incorrectly moved the tip of the
+   current branch, which has been corrected.
+   (merge bf1e28e0ad bw/rebase-autostash-keep-current-branch later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.

-git-filter-branch allows you to make complex shell-scripted rewrites
-of your Git history, but you probably don't need this flexibility if
-you're simply _removing unwanted data_ like large files or passwords.
-For those operations you may want to consider
-http://rtyley.github.io/bfg-repo-cleaner/[The BFG Repo-Cleaner],
-a JVM-based alternative to git-filter-branch, typically at least
-10-50x faster for those use-cases, and with quite different
-characteristics:
-
-* Any particular version of a file is cleaned exactly _once_. The BFG,
-  unlike git-filter-branch, does not give you the opportunity to
-  handle a file differently based on where or when it was committed
-  within your history. This constraint gives the core performance
-  benefit of The BFG, and is well-suited to the task of cleansing bad
-  data - you don't care _where_ the bad data is, you just want it
-  _gone_.
-
-* By default The BFG takes full advantage of multi-core machines,
-  cleansing commit file-trees in parallel. git-filter-branch cleans
-  commits sequentially (i.e. in a single-threaded manner), though it
-  _is_ possible to write filters that include their own parallelism,
-  in the scripts executed against each commit.
-
-* The http://rtyley.github.io/bfg-repo-cleaner/#examples[command options]
-  are much more restrictive than git-filter branch, and dedicated just
-  to the tasks of removing unwanted data- e.g:
-  `--strip-blobs-bigger-than 1M`.
+[[PERFORMANCE]]
+PERFORMANCE
+-----------
+
+The performance of git-filter-branch is glacially slow; its design makes it
+impossible for a backward-compatible implementation to ever be fast:
+
+* In editing files, git-filter-branch by design checks out each and
+every commit as it existed in the original repo.  If your repo has 10\^5
+files and 10\^5 commits, but each commit only modifies 5 files, then
+git-filter-branch will make you do 10\^10 modifications, despite only
+having (at most) 5*10^5 unique blobs.
+
+* If you try and cheat and try to make git-filter-branch only work on
+files modified in a commit, then two things happen
+
+  ** you run into problems with deletions whenever the user is simply
+     trying to rename files (because attempting to delete files that
+     don't exist looks like a no-op; it takes some chicanery to remap
+     deletes across file renames when the renames happen via arbitrary
+     user-provided shell)
+
+  ** even if you succeed at the map-deletes-for-renames chicanery, you
+     still technically violate backward compatibility because users are
+     allowed to filter files in ways that depend upon topology of
+     commits instead of filtering solely based on file contents or names
+     (though this has not been observed in the wild).
+
+* Even if you don't need to edit files but only want to e.g. rename or
+remove some and thus can avoid checking out each file (i.e. you can use
+--index-filter), you still are passing shell snippets for your filters.
+This means that for every commit, you have to have a prepared git repo
+where those filters can be run.  That's a significant setup.
+
+* Further, several additional files are created or updated per commit by
+git-filter-branch.  Some of these are for supporting the convenience
+functions provided by git-filter-branch (such as map()), while others
+are for keeping track of internal state (but could have also been
+accessed by user filters; one of git-filter-branch's regression tests
+does so).  This essentially amounts to using the filesystem as an IPC
+mechanism between git-filter-branch and the user-provided filters.
+Disks tend to be a slow IPC mechanism, and writing these files also
+effectively represents a forced synchronization point between separate
+processes that we hit with every commit.
+
+* The user-provided shell commands will likely involve a pipeline of
+commands, resulting in the creation of many processes per commit.
+Creating and running another process takes a widely varying amount of
+time between operating systems, but on any platform it is very slow
+relative to invoking a function.
+
+* git-filter-branch itself is written in shell, which is kind of slow.
+This is the one performance issue that could be backward-compatibly
+fixed, but compared to the above problems that are intrinsic to the
+design of git-filter-branch, the language of the tool itself is a
+relatively minor issue.
+
+  ** Side note: Unfortunately, people tend to fixate on the
+     written-in-shell aspect and periodically ask if git-filter-branch
+     could be rewritten in another language to fix the performance
+     issues.  Not only does that ignore the bigger intrinsic problems
+     with the design, it'd help less than you'd expect: if
+     git-filter-branch itself were not shell, then the convenience
+     functions (map(), skip_commit(), etc) and the `--setup` argument
+     could no longer be executed once at the beginning of the program
+     but would instead need to be prepended to every user filter (and
+     thus re-executed with every commit).
+
+The https://github.com/newren/git-filter-repo/[git filter-repo] tool is
+an alternative to git-filter-branch which does not suffer from these
+performance problems or the safety problems (mentioned below). For those
+with existing tooling which relies upon git-filter-branch, 'git
+repo-filter' also provides
+https://github.com/newren/git-filter-repo/blob/master/contrib/filter-repo-demos/filter-lamely[filter-lamely],
+a drop-in git-filter-branch replacement (with a few caveats).  While
+filter-lamely suffers from all the same safety issues as
+git-filter-branch, it at least ameloriates the performance issues a
+little.
+
+[[SAFETY]]
+SAFETY
+------
+
+git-filter-branch is riddled with gotchas resulting in various ways to
+easily corrupt repos or end up with a mess worse than what you started
+with:
+
+* Someone can have a set of "working and tested filters" which they
+document or provide to a coworker, who then runs them on a different OS
+where the same commands are not working/tested (some examples in the
+git-filter-branch manpage are also affected by this).  BSD vs. GNU
+userland differences can really bite.  If lucky, error messages are
+spewed.  But just as likely, the commands either don't do the filtering
+requested, or silently corrupt by making some unwanted change.  The
+unwanted change may only affect a few commits, so it's not necessarily
+obvious either.  (The fact that problems won't necessarily be obvious
+means they are likely to go unnoticed until the rewritten history is in
+use for quite a while, at which point it's really hard to justify
+another flag-day for another rewrite.)
+
+* Filenames with spaces are often mishandled by shell snippets since
+they cause problems for shell pipelines.  Not everyone is familiar with
+find -print0, xargs -0, git-ls-files -z, etc.  Even people who are
+familiar with these may assume such flags are not relevant because
+someone else renamed any such files in their repo back before the person
+doing the filtering joined the project.  And often, even those familiar
+with handling arguments with spaces may not do so just because they
+aren't in the mindset of thinking about everything that could possibly
+go wrong.
+
+* Non-ascii filenames can be silently removed despite being in a desired
+directory.  Keeping only wanted paths is often done using pipelines like
+`git ls-files | grep -v ^WANTED_DIR/ | xargs git rm`.  ls-files will
+only quote filenames if needed, so folks may not notice that one of the
+files didn't match the regex (at least not until it's much too late).
+Yes, someone who knows about core.quotePath can avoid this (unless they
+have other special characters like \t, \n, or "), and people who use
+ls-files -z with something other than grep can avoid this, but that
+doesn't mean they will.
+
+* Similarly, when moving files around, one can find that filenames with
+non-ascii or special characters end up in a different directory, one
+that includes a double quote character.  (This is technically the same
+issue as above with quoting, but perhaps an interesting different way
+that it can and has manifested as a problem.)
+
+* It's far too easy to accidentally mix up old and new history.  It's
+still possible with any tool, but git-filter-branch almost invites it.
+If lucky, the only downside is users getting frustrated that they don't
+know how to shrink their repo and remove the old stuff.  If unlucky,
+they merge old and new history and end up with multiple "copies" of each
+commit, some of which have unwanted or sensitive files and others which
+don't.  This comes about in multiple different ways:
+
+  ** the default to only doing a partial history rewrite ('--all' is not
+     the default and few examples show it)
+
+  ** the fact that there's no automatic post-run cleanup
+
+  ** the fact that --tag-name-filter (when used to rename tags) doesn't
+     remove the old tags but just adds new ones with the new name
+
+  ** the fact that little educational information is provided to inform
+     users of the ramifications of a rewrite and how to avoid mixing old
+     and new history.  For example, this man page discusses how users
+     need to understand that they need to rebase their changes for all
+     their branches on top of new history (or delete and reclone), but
+     that's only one of multiple concerns to consider.  See the
+     "DISCUSSION" section of the git filter-repo manual page for more
+     details.
+
+* Annotated tags can be accidentally converted to lightweight tags, due
+to either of two issues:
+
+  ** Someone can do a history rewrite, realize they messed up, restore
+     from the backups in refs/original/, and then redo their
+     git-filter-branch command.  (The backup in refs/original/ is not a
+     real backup; it dereferences tags first.)
+
+  ** Running git-filter-branch with either --tags or --all in your
+     <rev-list options>.  In order to retain annotated tags as
+     annotated, you must use --tag-name-filter (and must not have
+     restored from refs/original/ in a previously botched rewrite).
+
+* Any commit messages that specify an encoding will become corrupted
+by the rewrite; git-filter-branch ignores the encoding, takes the original
+bytes, and feeds it to commit-tree without telling it the proper
+encoding.  (This happens whether or not --msg-filter is used.)
+
+* Commit messages (even if they are all UTF-8) by default become
+corrupted due to not being updated -- any references to other commit
+hashes in commit messages will now refer to no-longer-extant commits.
+
+* There are no facilities for helping users find what unwanted crud they
+should delete, which means they are much more likely to have incomplete
+or partial cleanups that sometimes result in confusion and people
+wasting time trying to understand.  (For example, folks tend to just
+look for big files to delete instead of big directories or extensions,
+and once they do so, then sometime later folks using the new repository
+who are going through history will notice a build artifact directory
+that has some files but not others, or a cache of dependencies
+(node_modules or similar) which couldn't have ever been functional since
+it's missing some files.)
+
+* If --prune-empty isn't specified, then the filtering process can
+create hoards of confusing empty commits
+
+* If --prune-empty is specified, then intentionally placed empty
+commits from before the filtering operation are also pruned instead of
+just pruning commits that became empty due to filtering rules.
+
+* If --prune empty is specified, sometimes empty commits are missed
+and left around anyway (a somewhat rare bug, but it happens...)
+
+* A minor issue, but users who have a goal to update all names and
+emails in a repository may be led to --env-filter which will only update
+authors and committers, missing taggers.
+
+* If the user provides a --tag-name-filter that maps multiple tags to
+the same name, no warning or error is provided; git-filter-branch simply
+overwrites each tag in some undocumented pre-defined order resulting in
+only one tag at the end.  (A git-filter-branch regression test requires
+this surprising behavior.)
+
+Also, the poor performance of git-filter-branch often leads to safety
+issues:
+
+* Coming up with the correct shell snippet to do the filtering you want
+is sometimes difficult unless you're just doing a trivial modification
+such as deleting a couple files.  Unfortunately, people often learn if
+the snippet is right or wrong by trying it out, but the rightness or
+wrongness can vary depending on special circumstances (spaces in
+filenames, non-ascii filenames, funny author names or emails, invalid
+timezones, presence of grafts or replace objects, etc.), meaning they
+may have to wait a long time, hit an error, then restart.  The
+performance of git-filter-branch is so bad that this cycle is painful,
+reducing the time available to carefully re-check (to say nothing about
+what it does to the patience of the person doing the rewrite even if
+they do technically have more time available).  This problem is extra
+compounded because errors from broken filters may not be shown for a
+long time and/or get lost in a sea of output.  Even worse, broken
+filters often just result in silent incorrect rewrites.
+
+* To top it all off, even when users finally find working commands, they
+naturally want to share them.  But they may be unaware that their repo
+didn't have some special cases that someone else's does.  So, when
+someone else with a different repository runs the same commands, they
+get hit by the problems above.  Or, the user just runs commands that
+really were vetted for special cases, but they run it on a different OS
+where it doesn't work, as noted above.

+Using many promisor remotes
+---------------------------
+
+Many promisor remotes can be configured and used.
+
+This allows for example a user to have multiple geographically-close
+cache servers for fetching missing blobs while continuing to do
+filtered `git-fetch` commands from the central server.
+
+When fetching objects, promisor remotes are tried one after the other
+until all the objects have been fetched.
+
+Remotes that are considered "promisor" remotes are those specified by
+the following configuration variables:
+
+- `extensions.partialClone = <name>`
+
+- `remote.<name>.promisor = true`
+
+- `remote.<name>.partialCloneFilter = ...`
+
+Only one promisor remote can be configured using the
+`extensions.partialClone` config variable. This promisor remote will
+be the last one tried when fetching objects.
+
+We decided to make it the last one we try, because it is likely that
+someone using many promisor remotes is doing so because the other
+promisor remotes are better for some reason (maybe they are closer or
+faster for some kind of objects) than the origin, and the origin is
+likely to be the remote specified by extensions.partialClone.
+
+This justification is not very strong, but one choice had to be made,
+and anyway the long term plan should be to make the order somehow
+fully configurable.
+
+For now though the other promisor remotes will be tried in the order
+they appear in the config file.
