Git 2.11 Release Notes
======================
+Backward compatibility notes.
+
+ * An empty string used as a pathspec element has always meant
+ 'everything matches', but it is too easy to write a script that
+ finds a path to remove in $path and run 'git rm "$paht"' by
+ mistake (when the user meant to give "$path"), which ends up
+ removing everything. This release starts warning about the
+ use of an empty string that is used for 'everything matches' and
+ 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.
+
+ * The historical argument order "git merge <msg> HEAD <commit>..."
+ has been deprecated for quite some time, and will be removed in the
+ next release (not this one).
+
+ * The default abbreviation length, which has historically been 7, now
+ scales as the repository grows, using the approximate number of
+ objects in the repository and a bit of math around the birthday
+ paradox. The logic suggests to use 12 hexdigits for the Linux
+ kernel, and 9 to 10 for Git itself.

Updates since v2.10
-------------------
UI, Workflows & Features
+ * Comes with new version of git-gui, now at its 0.21.0 tag.

and [PATCH 1/1] by default.

(merge 26a7b23429 ps/http-gssapi-cred-delegation later to maint).
+ * "git mergetool" learned to honor "-O<orderfile>" to control the
+ order of paths to present to the end user.
+
+ * "git diff/log --ws-error-highlight=<kind>" lacked the corresponding
+ configuration variable (diff.wsErrorHighlight) to set it by default.
+
+ * "git ls-files" learned the "--recurse-submodules" option
+ to get a listing of tracked files across submodules (i.e. this
+ only works with the "--cached" option, not for listing untracked or
+ ignored files). This would be a useful tool to sit on the upstream
+ side of a pipe that is read with xargs to work on all working tree
+ files from the top-level superproject.
+
+ * A new credential helper that talks via "libsecret" with
+ implementations of XDG Secret Service API has been added to
+ contrib/credential/.
+
+ * The GPG verification status shown by the "%G?" pretty format specifier
+ was not rich enough to differentiate a signature made by an expired
+ key, a signature made by a revoked key, etc. New output letters
+ have been assigned to express them.
+
+ * In addition to purely abbreviated commit object names, "gitweb"
+ learned to turn "git describe" output (e.g. v2.9.3-599-g2376d31787)
+ into clickable links in its output.
+
+ * "git commit" created an empty commit when invoked with an index
+ consisting solely of intend-to-add paths (added with "git add -N").
+ It now requires the "--allow-empty" option to create such a commit.
+ The same logic prevented "git status" from showing such paths as "new files" in the
+ "Changes not staged for commit" section.
+
+ * The smudge/clean filter API spawns an external process
+ to filter the contents of each path that has a filter defined. A
+ new type of "process" filter API has been added to allow the first
+ request to run the filter for a path to spawn a single process, and
+ all filtering is served by this single process for multiple
+ paths, reducing the process creation overhead.
+
+ * The user always has to say "stash@{$N}" when naming a single
+ element in the default location of the stash, i.e. reflogs in
+ refs/stash. The "git stash" command learned to accept "git stash
+ apply 4" as a short-hand for "git stash apply stash@{4}".

+ * We call "qsort(array, nelem, sizeof(array[0]), fn)", and most of

+
+ * "git pack-objects" in a repository with many packfiles used to

+ the packfiles are now optimized by checking the most-recently-used
+ packfile first.
+ (merge c9af708b1a jk/pack-objects-optim-mru later to maint).
+
+ * Codepaths involved in interacting alternate object stores have
+ been cleaned up.
+
+ * In order for the receiving end of "git push" to inspect the
+ received history and decide to reject the push, the objects sent
+ from the sending end need to be made available to the hook and
+ the mechanism for the connectivity check, and this was done
+ traditionally by storing the objects in the receiving repository
+ and letting "git gc" expire them. Instead, store the newly
+ received objects in a temporary area, and make them available by
+ reusing the alternate object store mechanism to them only while we
+ decide if we accept the check, and once we decide, either migrate
+ them to the repository or purge them immediately.
+
+ * The require_clean_work_tree() helper was recreated in C when "git
+ pull" was rewritten from shell; the helper is now made available to
+ other callers in preparation for upcoming "rebase -i" work.
+
+ * "git upload-pack" had its code cleaned-up and performance improved
+ by reducing use of timestamp-ordered commit-list, which was
+ replaced with a priority queue.
+
+ * "git diff --no-index" codepath has been updated not to try to peek
+ into a .git/ directory that happens to be under the current
+ directory, when we know we are operating outside any repository.
+
+ * Update of the sequencer codebase to make it reusable to reimplement
+ "rebase -i" continues.
+
+ * Git generally does not explicitly close file descriptors that were
+ open in the parent process when spawning a child process, but most
+ of the time the child does not want to access them. As Windows does
+ not allow removing or renaming a file that has a file descriptor
+ open, a slow-to-exit child can even break the parent process by
+ holding onto them. Use O_CLOEXEC flag to open files in various
+ codepaths.
+
+ * Update "interpret-trailers" machinery and teach it that people in
+ the real world write all sorts of cruft in the "trailer" that was
+ originally designed to have the neat-o "Mail-Header: like thing"
+ and nothing else.

* "git gc --aggressive" used to limit the delta-chain length to 250,

* "git checkout <word>" does not follow the usual disambiguation
rules when the <word> can be both a rev and a path, to allow
file 'foo' in the working tree without having to disambiguate.
This was poorly documented and the check was incorrect when the
command was run from a subdirectory.
- (merge b829b94 nd/checkout-disambiguation later to maint).
* Some codepaths in "git diff" used regexec(3) on a buffer that was
mmap(2)ed, which may not have a terminating NUL, leading to a read
beyond the end of the mapped region. This was fixed by introducing
a regexec_buf() helper that takes a <ptr,len> pair with REG_STARTEND
extension.
- (merge b7d36ff js/regexec-buf later to maint).
* The procedure to build Git on Mac OS X for Travis CI hardcoded the

+ * The existing "git fetch --depth=<n>" option was hard to use
+ correctly when making the history of an existing shallow clone

+ * The http.emptyauth configuration variable is a way to allow an empty username to

+ Kerberos. We took an unspecified (NULL) username and sent ":"
+ (i.e. no username, no password) to CURLOPT_USERPWD, but did not do
+ the same when the username is explicitly set to an empty string.
+
+ * "git clone" of a local repository can be done at the filesystem

+
+ * Documentation for "git commit" was updated to clarify that "commit

+
+ * In a worktree created via "git
+ worktree", "git checkout" attempts to protect users from confusion
+ by refusing to check out a branch that is already checked out in
+ another worktree. However, this also prevented checking out a
+ branch which is designated as the primary branch of a bare
+ repository, in a worktree that is connected to the bare
+ repository. The check has been corrected to allow it.
+
+ * "git rebase" immediately after "git clone" failed to find the fork
+ point from the upstream.
+
+ * When fetching from a remote that has many tags that are irrelevant
+ to branches we are following, we used to waste way too many cycles
+ checking if the object pointed at by a tag (that we are not
+ going to fetch!) exists in our repository too carefully.
+
+ * Protect our code from over-eager compilers.
+
+ * Recent git allows submodule.<name>.branch to use a special token
+ "." instead of the branch name; the documentation has been updated
+ to describe it.
+
+ * "git send-email" attempts to pick up valid e-mails from the
+ trailers, but people in the real world write non-addresses there, like
+ "Cc: Stable <add@re.ss> # 4.8+", which broke the output depending
+ on the availability and vintage of the Mail::Address perl module.
+ (merge dcfafc5214 mm/send-email-cc-cruft-after-address later to maint).
+
+ * The Travis CI configuration we ship ran the tests with the --verbose
+ option but this risks non-TAP output that happens to be "ok" to be
+ misinterpreted as TAP signalling a test that passed. This resulted
+ in unnecessary failures. This has been corrected by introducing a
+ new mode to run our tests in the test harness to send the verbose
+ output separately to the log file.
+
+ * Some AsciiDoc formatters mishandle a displayed illustration with
+ tabs in it. Adjust a few of them in merge-base documentation to
