diff-tree") now
    recursively descends into trees by default.

  - "git diff" does not show differences that come only from
    stat-dirtiness in the form of "diff --git" header anymore.
    It runs "update-index --refresh" silently as needed.

  - "git tag -l" used to match tags by globbing its parameter as if it
    has wildcard '*' on both ends, which made "git tag -l gui" to match
    tag 'gitgui-0.7.0'; this was very annoying.  You now have to add
    asterisk on the sides you want to wildcard yourself.

  - The editor to use with many interactive commands can be
    overridden with GIT_EDITOR environment variable, or if it
    does not exist, with core.editor configuration variable.  As
    before, if you have neither, environment variables VISUAL
    and EDITOR are consulted in this order, and then finally we
    fall back on "vi".

  - "git rm --cached" does not complain when removing a newly
    added file from the index anymore.

  - Options to "git log" to affect how --grep/--author options look for
    given strings now have shorter abbreviations.  -i is for ignore case,
    and -E is for extended regexp.

  - "git log" learned --log-size to show the number of bytes in
    the log message part of the output to help qgit.

  - "git log --name-status" does not require you to give "-r" anymore.
    As a general rule, Porcelain commands should recurse when showing
    diff.

  - "git format-patch --root A" can be used to format everything
    since the beginning up to A.  This was supported with
    "git format-patch --root A A" for a long time, but was not
    properly documented.

  - "git svn dcommit" retains local merge information.

  - "git svnimport" allows an empty string to be specified as the
    trunk/ directory.  This is necessary to suck data from a SVN
    repository that doe not have trunk/ branches/ and tags/ organization
    at all.

  - "git config" to set values also honors type flags like --bool
    and --int.

  - core.quotepath configuration can be used to make textual git
    output to emit most of the characters in the path literally.

  - "git mergetool" chooses its backend more wisely, taking
    notice of its environment such as use of X, Gnome/KDE, etc.

  - "gitweb" shows merge commits a lot nicer than before.  The
    default view uses more compact --cc format, while the UI
    allows to choose normal diff with any parent.

  - snapshot files "gitweb" creates from a repository at
    $path/$project/.git are more useful.  We use $project part
    in the filename, which we used to discard.

  - "git cvsimport" creates lightweight tags; there is no
    interesting information we can record in an annotated tag,
    and the handcrafted ones the old code created was not
    properly formed anyway.

  - "git push" pretends that you immediately fetched back from
    the remote by updating corresponding remote tracking
    branches if you have any.

  - The diffstat given after a merge (or a pull) honors the
    color.diff configuration.

  - "git commit --amend" is now compatible with various message source
    options such as -m/-C/-c/-F.

  - "git apply --whitespace=strip" removes blank lines added at
    the end of the file.

  - "git fetch" over git native protocols with "-v" option shows
    connection status, and the IP address of the other end, to
    help diagnosing problems.

  - We used to have core.legacyheaders configuration, when
    set to false, allowed git to write loose objects in a format
    that mimics the format used by objects stored in packs.  It
    turns out that this was not so useful.  Although we will
    continue to read objects written in that format, we do not
    honor that configuration anymore and create loose objects in
    the legacy/traditional format.

  - "--find-copies-harder" option to diff family can now be
    spelled as "-C -C" for brevity.

  - "git mailsplit" (hence "git am") can read from Maildir
    formatted mailboxes.

  - "git cvsserver" does not
