 Git v2.11.1 Release Notes
 =========================

 Fixes since v2.11
 -----------------

  * The default Travis-CI configuration specifies newer P4 and GitLFS.

  * The character width table has been updated to match Unicode 9.0

  * Update the isatty() emulation for Windows by updating the previous
    hack that depended on internals of (older) MSVC runtime.

  * "git rev-parse --symbolic" failed with a more recent notation like
    "HEAD^-1" and "HEAD^!".

  * An empty directory in a working tree that can simply be nuked used
    to interfere while merging or cherry-picking a change to create a
    submodule directory there, which has been fixed..

  * The code in "git push" to compute if any commit being pushed in the
    superproject binds a commit in a submodule that hasn't been pushed
    out was overly inefficient, making it unusable even for a small
    project that does not have any submodule but have a reasonable
    number of refs.

  * "git push --dry-run --recurse-submodule=on-demand" wasn't
    "--dry-run" in the submodules.

  * The output from "git worktree list" was made in readdir() order,
    and was unstable.

  * mergetool.<tool>.trustExitCode configuration variable did not apply
    to built-in tools, but now it does.

  * "git p4" LFS support was broken when LFS stores an empty blob.

  * Fix a corner case in merge-recursive regression that crept in
    during 2.10 development cycle.

  * Update the error messages from the dumb-http client when it fails
    to obtain loose objects; we used to give sensible error message
    only upon 404 but we now forbid unexpected redirects that needs to
    be reported with something sensible.

  * When diff.renames configuration is on (and with Git 2.9 and later,
    it is enabled by default, which made it worse), "git stash"
    misbehaved if a file is removed and another file with a very
    similar content is added.

  * "git diff --no-index" did not take "--no-abbrev" option.

  * "git difftool --dir-diff" had a minor regression when started from
    a subdirectory, which has been fixed.

  * "git commit --allow-empty --only" (no pathspec) with dirty index
    ought to be an acceptable way to create a new commit that does not
    change any paths, but it was forbidden, perhaps because nobody
    needed it so far.

  * A pathname that begins with "//" or "\\" on Windows is special but
    path normalization logic was unaware of it.

  * "git pull --rebase", when there is no new commits on our side since
    we forked from the upstream, should be able to fast-forward without
    invoking "git rebase", but it didn't.

  * The way to specify hotkeys to "xxdiff" that is used by "git
    mergetool" has been modernized to match recent versions of xxdiff.

  * Unlike "git am --abort", "git cherry-pick --abort" moved HEAD back
    to where cherry-pick started while picking multiple changes, when
    the cherry-pick stopped to ask for help from the user, and the user
    did "git reset --hard" to a different commit in order to re-attempt
    the operation.

  * Code cleanup in shallow boundary computation.

  * A recent update to receive-pack to make it easier to drop garbage
    objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot
    have a pathname with a colon in it (no surprise!), and this in turn
    made it impossible to push into a repository at such a path.  This
    has been fixed by introducing a quoting mechanism used when
    appending such a path to the colon-separated list.

  * The function usage_msg_opt() has been updated to say "fatal:"
    before the custom message programs give, when they want to die
    with a message about wrong command line options followed by the
    standard usage string.

  * "git index-pack --stdin" needs an access to an existing repository,
    but "git index-pack file.pack" to generate an .idx file that
    corresponds to a packfile does not.

  * Fix for NDEBUG builds.

  * A lazy "git push" without refspec did not internally use a fully
    specified refspec to perform 'current', 'simple', or 'upstream'
    push, causing unnecessary "ambiguous ref" errors.

  * "git p4" misbehaved when swapping a directory and a symbolic link.

  * Even though an fix was attempted in Git 2.9.3 days, but running
    "git difftool --dir-diff" from a subdirectory never worked. This
    has been fixed.

  * "git p4" that tracks multile p4 paths imported a single changelist
    that touches files in these multiple paths as one commit, followed
    by many empty commits.  This has been fixed.

  * A potential but unlikely buffer overflow in Windows port has been
    fixed.

  * When the http server gives an incomplete response to a smart-http
    rpc call, it could lead to client waiting for a full response that
    will never come.  Teach the client side to notice this condition
    and abort the transfer.

  * Some platforms no longer understand "latin-1" that is still seen in
    the wild in e-mail headers; replace them with "iso-8859-1" that is
    more widely known when conversion fails from/to it.

  * Update the procedure to generate "tags" for developer support.

  * Update the definition of the MacOSX test environment used by
    TravisCI.

  * A few git-svn updates.

  * Compression setting for producing packfiles were spread across
    three codepaths, one of which did not honor any configuration.
    Unify these so that all of them honor core.compression and
    pack.compression variables the same way.

  * "git fast-import" sometimes mishandled while rebalancing notes
    tree, which has been fixed.

  * Recent update to the default abbreviation length that auto-scales
    lacked documentation update, which has been corrected.

  * Leakage of lockfiles in the config subsystem has been fixed.

  * It is natural that "git gc --auto" may not attempt to pack
    everything into a single pack, and there is no point in warning
    when the user has configured the system to use the pack bitmap,
    leading to disabling further "gc".

  * "git archive" did not read the standard configuration files, and
    failed to notice a file that is marked as binary via the userdiff
    driver configuration.

  * "git blame --porcelain" misidentified the "previous" <commit, path>
    pair (aka "source") when contents came from two or more files.

  * "git rebase -i" with a recent update started showing an incorrect
    count when squashing more than 10 commits.

  * "git <cmd> @{push}" on a detached HEAD used to segfault; it has
    been corrected to error out with a message.

  * Tighten a test to avoid mistaking an extended ERE regexp engine as
    a PRE regexp engine.

  * Typing ^C to pager, which usually does not kill it, killed Git and
    took the pager down as a collateral damage in certain process-tree
    structure.  This has been fixed.

 Also contains various documentation updates and code clean-ups.
