+Git v2.13.1 Release Notes
+=========================
+
+Fixes since v2.13
+-----------------
+
+ * The Web interface to gmane news archive is long gone, even though
+   the articles are still accessible via NTTP.  Replace the links with
+   ones to public-inbox.org.  Because their message identification is
+   based on the actual message-id, it is likely that it will be easier
+   to migrate away from it if/when necessary.
+
+ * Update tests to pass under GETTEXT_POISON (a mechanism to ensure
+   that output strings that should not be translated are not
+   translated by mistake), and tell TravisCI to run them.
+
+ * Setting "log.decorate=false" in the configuration file did not take
+   effect in v2.13, which has been corrected.
+
+ * An earlier update to test 7400 needed to be skipped on CYGWIN.
+
+ * Git sometimes gives an advice in a rhetorical question that does
+   not require an answer, which can confuse new users and non native
+   speakers.  Attempt to rephrase them.
+
+ * "git read-tree -m" (no tree-ish) gave a nonsense suggestion "use
+   --empty if you want to clear the index".  With "-m", such a request
+   will still fail anyway, as you'd need to name at least one tree-ish
+   to be merged.
+
+ * The codepath in "git am" that is used when running "git rebase"
+   leaked memory held for the log message of the commits being rebased.
+
+ * "pack-objects" can stream a slice of an existing packfile out when
+   the pack bitmap can tell that the reachable objects are all needed
+   in the output, without inspecting individual objects.  This
+   strategy however would not work well when "--local" and other
+   options are in use, and need to be disabled.
+
+ * Clarify documentation for include.path and includeIf.<condition>.path
+   configuration variables.
+
+ * Tag objects, which are not reachable from any ref, that point at
+   missing objects were mishandled by "git gc" and friends (they
+   should silently be ignored instead)
+
+ * A few http:// links that are redirected to https:// in the
+   documentation have been updated to https:// links.
+
+ * Make sure our tests would pass when the sources are checked out
+   with "platform native" line ending convention by default on
+   Windows.  Some "text" files out tests use and the test scripts
+   themselves that are meant to be run with /bin/sh, ought to be
+   checked out with eol=LF even on Windows.
+
+ * Fix memory leaks pointed out by Coverity (and people).
+
+ * The receive-pack program now makes sure that the push certificate
+   records the same set of push options used for pushing.
+
+ * "git cherry-pick" and other uses of the sequencer machinery
+   mishandled a trailer block whose last line is an incomplete line.
+   This has been fixed so that an additional sign-off etc. are added
+   after completing the existing incomplete line.
+
+ * The shell completion script (in contrib/) learned "git stash" has
+   a new "push" subcommand.
+
+Also contains various documentation updates and code clean-ups.

+Git 2.14 Release Notes
+======================
+
+Backward compatibility notes.
+
+ * Use of an empty string as a pathspec element that is used for
+   'everything matches' is still warned and Git asks users to use a
+   more explicit '.' for that instead.  The hope is that existing
+   users will not mind this change, and eventually the warning can be
+   turned into a hard error, upgrading the deprecation into removal of
+   this (mis)feature.  That is not scheduled to happen in the upcoming
+   release (yet).
+
+ * Git now avoids blindly falling back to ".git" when the setup
+   sequence said we are _not_ in Git repository.  A corner case that
+   happens to work right now may be broken by a call to die("BUG").
+   We've tried hard to locate such cases and fixed them, but there
+   might still be cases that need to be addressed--bug reports are
+   greatly appreciated.
+
+
+Updates since v2.13
+-------------------
+
+UI, Workflows & Features
+
+ * The colors in which "git status --short --branch" showed the names
+   of the current branch and its remote-tracking branch are now
+   configurable.
+
+ * "git clone" learned the "--no-tags" option not to fetch all tags
+   initially, and also set up the tagopt not to follow any tags in
+   subsequent fetches.
+
+ * "git archive --format=zip" learned to use zip64 extension when
+   necessary to go beyond the 4GB limit.
+   (merge 867e40ff3a rs/large-zip later to maint).
+
+ * "git reset" learned "--recurse-submodules" option.
+
+ * "git diff --submodule=diff" now recurses into nested submodules.
+   (merge 5a5221427c jk/diff-submodule-diff-inline later to maint).
+
+ * "git repack" learned to accept the --threads=<n> option and pass it
+   to pack-objects.
+
+ * "git send-email" learned to run sendemail-validate hook to inspect
+   and reject a message before sending it out.
+   (merge 6489660b4b jt/send-email-validate-hook later to maint).
+
+ * There is no good reason why "git fetch $there $sha1" should fail
+   when the $sha1 names an object at the tip of an advertised ref,
+   even when the other side hasn't enabled allowTipSHA1InWant.
+
+ * The recently introduced "[includeIf "gitdir:$dir"] path=..."
+   mechansim has further been taught to take symlinks into account.
+   The directory "$dir" specified in "gitdir:$dir" may be a symlink to
+   a real location, not something that $(getcwd) may return.  In such
+   a case, a realpath of "$dir" is compared with the real path of the
+   current repository to determine if the contents from the named path
+   should be included.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The default packed-git limit value has been raised on larger
+   platforms to save "git fetch" from a (recoverable) failure while
+   "gc" is running in parallel.
+
+ * Code to update the cache-tree has been tightened so that we won't
+   accidentally write out any 0{40} entry in the tree object.
+   (merge a96d3cc3f6 jk/no-null-sha1-in-cache-tree later to maint).
+
+ * Attempt to allow us notice "fishy" situation where we fail to
+   remove the temporary directory used during the test.
+
+ * Travis CI gained a task to format the documentation with both
+   AsciiDoc and AsciiDoctor.
+   (merge 505ad91304 ls/travis-doc-asciidoctor later to maint).
+
+ * Some platforms have ulong that is smaller than time_t, and our
+   historical use of ulong for timestamp would mean they cannot
+   represent some timestamp that the platform allows.  Invent a
+   separate and dedicated timestamp_t (so that we can distingiuish
+   timestamps and a vanilla ulongs, which along is already a good
+   move), and then declare uintmax_t is the type to be used as the
+   timestamp_t.
+
+ * We can trigger Windows auto-build tester (credits: Dscho &
+   Microsoft) from our existing Travis CI tester now.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * Simplify parse_pathspec() codepath and stop it from looking at the
+   default in-core index.
+   (merge 08de9151a8 bw/pathspec-sans-the-index later to maint).
+
+ * Add perf-test for wildmatch.
+   (merge 62ca75a6b9 ab/perf-wildmatch later to maint).
+
+ * Code from "conversion using external process" codepath has been
+   extracted to a separate sub-process.[ch] module.
+   (merge 4f2a2e9f0e bp/sub-process-convert-filter later to maint).
+

+Fixes since v2.13
+-----------------
+
+Unless otherwise noted, all the fixes since v2.13 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git gc" did not interact well with "git worktree"-managed
+   per-worktree refs.
+
+ * "git cherry-pick" and other uses of the sequencer machinery
+   mishandled a trailer block whose last line is an incomplete line.
+   This has been fixed so that an additional sign-off etc. are added
+   after completing the existing incomplete line.
+   (merge 44dc738a39 jt/use-trailer-api-in-commands later to maint).
+
+ * The codepath in "git am" that is used when running "git rebase"
+   leaked memory held for the log message of the commits being rebased.
+   (merge 721f5f1e35 jk/am-leakfix later to maint).
+
+ * "git clone --config var=val" is a way to populate the
+   per-repository configuration file of the new repository, but it did
+   not work well when val is an empty string.  This has been fixed.
+   (merge db4eca1fea jn/clone-add-empty-config-from-command-line later to maint).
+
+ * Setting "log.decorate=false" in the configuration file did not take
+   effect in v2.13, which has been corrected.
+   (merge c74271aae7 ah/log-decorate-default-to-auto later to maint).
+
+ * A few codepaths in "checkout" and "am" working on an unborn branch
+   tried to access an uninitialized piece of memory.
+   (merge 57e0ef0e0e rs/checkout-am-fix-unborn later to maint).
+
+ * The Web interface to gmane news archive is long gone, even though
+   the articles are still accessible via NTTP.  Replace the links with
+   ones to public-inbox.org.  Because their message identification is
+   based on the actual message-id, it is likely that it will be easier
+   to migrate away from it if/when necessary.
+   (merge 5840eb9d14 ab/doc-replace-gmane-links later to maint).
+
+ * The receive-pack program now makes sure that the push certificate
+   records the same set of push options used for pushing.
+   (merge cbaf82cc6b jt/push-options-doc later to maint).
+
+ * Tests have been updated to pass under GETTEXT_POISON (a mechanism
+   to ensure that output strings that should not be translated are
+   not translated by mistake), and TravisCI is told to run them.
+   (merge b8e188f6f5 ab/fix-poison-tests later to maint).
+
+ * "git checkout --recurse-submodules" did not quite work with a
+   submodule that itself has submodules.
+   (merge 218c883783 sb/checkout-recurse-submodules later to maint).
+
+ * Plug some leaks and updates internal API used to implement the
+   split index feature to make it easier to avoid such a leak in the
+   future.
+   (merge de950c5773 nd/split-index-unshare later to maint).
+
+ * "pack-objects" can stream a slice of an existing packfile out when
+   the pack bitmap can tell that the reachable objects are all needed
+   in the output, without inspecting individual objects.  This
+   strategy however would not work well when "--local" and other
+   options are in use, and need to be disabled.
+   (merge da5a1f8100 jk/disable-pack-reuse-when-broken later to maint).
+
+ * Fix memory leaks pointed out by Coverity (and people).
+   (merge 443a12f37b js/plug-leaks later to maint).
+
+ * "git read-tree -m" (no tree-ish) gave a nonsense suggestion "use
+   --empty if you want to clear the index".  With "-m", such a request
+   will still fail anyway, as you'd need to name at least one tree-ish
+   to be merged.
+   (merge b9b10d3681 jc/read-tree-empty-with-m later to maint).
+
+ * Make sure our tests would pass when the sources are checked out
+   with "platform native" line ending convention by default on
+   Windows.  Some "text" files out tests use and the test scripts
+   themselves that are meant to be run with /bin/sh, ought to be
+   checked out with eol=LF even on Windows.
+   (merge 2779f66505 js/eol-on-ourselves later to maint).
+
+ * Introduce the BUG() macro to improve die("BUG: ...").
+   (merge 3d7dd2d3b6 jk/bug-to-abort later to maint).
+
+ * Clarify documentation for include.path and includeIf.<condition>.path
+   configuration variables.
+   (merge ce933ebd5a jk/doc-config-include later to maint).
+
+ * Git sometimes gives an advice in a rhetorical question that does
+   not require an answer, which can confuse new users and non native
+   speakers.  Attempt to rephrase them.
+   (merge 6963893943 ja/do-not-ask-needless-questions later to maint).
+
+ * A few http:// links that are redirected to https:// in the
+   documentation have been updated to https:// links.
+   (merge 5e68729fd9 jk/update-links-in-docs later to maint).
+
+ * "git for-each-ref --format=..." with %(HEAD) in the format used to
+   resolve the HEAD symref as many times as it had processed refs,
+   which was wasteful, and "git branch" shared the same problem.
+   (merge 613a0e52ea kn/ref-filter-branch-list later to maint).
+
+ * Regression fix to topic recently merged to 'master'.
+   (merge d096d7f1ef pw/rebase-i-regression-fix later to maint).
+
+ * The shell completion script (in contrib/) learned "git stash" has
+   a new "push" subcommand.
+   (merge 3851e4483f tg/stash-push-fixup later to maint).
+
+ * "git interpret-trailers", when used as GIT_EDITOR for "git commit
+   -v", looked for and appended to a trailer block at the very end,
+   i.e. at the end of the "diff" output.  The command has been
+   corrected to pay attention to the cut-mark line "commit -v" adds to
+   the buffer---the real trailer block should appear just before it.
+   (merge d76650b8d1 bm/interpret-trailers-cut-line-is-eom later to maint).
+
+ * A test allowed both "git push" and "git receive-pack" on the other
+   end write their traces into the same file.  This is OK on platforms
+   that allows atomically appending to a file opened with O_APPEND,
+   but on other platforms led to a mangled output, causing
+   intermittent test failures.  This has been fixed by disabling
+   traces from "receive-pack" in the test.
+   (merge 71406ed4d6 jk/alternate-ref-optim later to maint).
+
+ * Tag objects, which are not reachable from any ref, that point at
+   missing objects were mishandled by "git gc" and friends (they
+   should silently be ignored instead)
+   (merge a3ba6bf10a jk/ignore-broken-tags-when-ignoring-missing-links later to maint).
+
+ * "git describe --contains" penalized light-weight tags so much that
+   they were almost never considered.  Instead, give them about the
+   same chance to be considered as an annotated tag that is the same
+   age as the underlying commit would.
+   (merge ef1e74065c jc/name-rev-lw-tag later to maint).
+
+ * The "run-command" API implementation has been made more robust
+   against dead-locking in a threaded environment.
+   (merge e3f43ce765 bw/forking-and-threading later to maint).
+
+ * A recent update to t5545-push-options.sh started skipping all the
+   tests in the script when a web server testing is disabled or
+   unavailable, not just the ones that require a web server.  Non HTTP
+   tests have been salvaged to always run in this script.
+   (merge 2e397e4ddf jc/skip-test-in-the-middle later to maint).
+
+ * "git send-email" now uses Net::SMTP::SSL, which is obsolete, only
+   when needed.  Recent versions of Net::SMTP can do TLS natively.
+   (merge 0ead000c3a dk/send-email-avoid-net-smtp-ssl-when-able later to maint).
+
+ * "foo\bar\baz" in "git fetch foo\bar\baz", even though there is no
+   slashes in it, cannot be a nickname for a remote on Windows, as
+   that is likely to be a pathname on a local filesystem.
+   (merge d9244ecf4f js/bs-is-a-dir-sep-on-windows later to maint).
+
+ * "git clean -d" used to clean directories that has ignored files,
+   even though the command should not lose ignored ones without "-x".
+   "git status --ignored"  did not list ignored and untracked files
+   without "-uall".  These have been corrected.
+   (merge 6b1db43109 sl/clean-d-ignored-fix later to maint).
+
+ * The result from "git diff" that compares two blobs, e.g. "git diff
+   $commit1:$path $commit2:$path", used to be shown with the full
+   object name as given on the command line, but it is more natural to
+   use the $path in the output and use it to look up .gitattributes.
+   (merge 30d005c020 jk/diff-blob later to maint).
+
+ * The "collision detecting" SHA-1 implementation shipped with 2.13
+   was quite broken on some big-endian platforms and/or platforms that
+   do not like unaligned fetches.  Update to the upstream code which

+sub-process API
+===============
+
+The sub-process API makes it possible to run background sub-processes
+for the entire lifetime of a Git invocation. If Git needs to communicate
+with an external process multiple times, then this can reduces the process
+invocation overhead. Git and the sub-process communicate through stdin and
+stdout.
+
+The sub-processes are kept in a hashmap by command name and looked up
+via the subprocess_find_entry function.  If an existing instance can not
+be found then a new process should be created and started.  When the
+parent git command terminates, all sub-processes are also terminated.
+
+This API is based on the run-command API.

  * Calling sequence
  * ----------------
+ *
  * - Allocate and initialize a `struct ref_transaction` by calling
  *   `ref_transaction_begin()`.
  *
- * - List intended ref updates by calling functions like
- *   `ref_transaction_update()` and `ref_transaction_create()`.
- *
- * - Call `ref_transaction_commit()` to execute the transaction.
- *   If this succeeds, the ref updates will have taken place and
- *   the transaction cannot be rolled back.
- *
- * - Instead of `ref_transaction_commit`, use
- *   `initial_ref_transaction_commit()` if the ref database is known
- *   to be empty (e.g. during clone).  This is likely to be much
- *   faster.
- *
- * - At any time call `ref_transaction_free()` to discard the
- *   transaction and free associated resources.  In particular,
- *   this rolls back the transaction if it has not been
- *   successfully committed.
+ * - Specify the intended ref updates by calling one or more of the
+ *   following functions:
+ *   - `ref_transaction_update()`
+ *   - `ref_transaction_create()`
+ *   - `ref_transaction_delete()`
+ *   - `ref_transaction_verify()`
+ *
+ * - Then either:
+ *
+ *   - Optionally call `ref_transaction_prepare()` to prepare the
+ *     transaction. This locks all references, checks preconditions,
+ *     etc. but doesn't finalize anything. If this step fails, the
+ *     transaction has been closed and can only be freed. If this step
+ *     succeeds, then `ref_transaction_commit()` is almost certain to
+ *     succeed. However, you can still call `ref_transaction_abort()`
+ *     if you decide not to commit the transaction after all.
+ *
+ *   - Call `ref_transaction_commit()` to execute the transaction,
+ *     make the changes permanent, and release all locks. If you
+ *     haven't already called `ref_transaction_prepare()`, then
+ *     `ref_transaction_commit()` calls it for you.
+ *
+ *   Or
+ *
+ *   - Call `initial_ref_transaction_commit()` if the ref database is
+ *     known to be empty and have no other writers (e.g. during
+ *     clone). This is likely to be much faster than
+ *     `ref_transaction_commit()`. `ref_transaction_prepare()` should
+ *     *not* be called before `initial_ref_transaction_commit()`.
+ *
+ * - Then finally, call `ref_transaction_free()` to free the
+ *   `ref_transaction` data structure.
+ *
+ * At any time before calling `ref_transaction_commit()`, you can call
+ * `ref_transaction_abort()` to abort the transaction, rollback any
+ * locks, and free any associated resources (including the
+ * `ref_transaction` data structure).
+ *
+ * Putting it all together, a complete reference update looks like
