output does not go to tty.

  - "git fetch" between repositories with many refs were slow
    even when there are not many changes that needed
    transferring.  This has been sped up by partially rewriting
    the heaviest parts in C.

  - "git mailinfo" which splits an e-mail into a patch and the
    meta-information was rewritten, thanks to Don Zickus.  It
    handles nested multipart better.  The command was broken for
    a brief period on 'master' branch since 1.5.0 but the
    breakage is fixed now.

  - send-email learned configurable bcc and chain-reply-to.

  - "git remote show $remote" also talks about branches that
    would be pushed if you run "git push remote".

  - Using objects from packs is now seriously optimized by clever
    use of a cache.  This should be most noticeable in git-log
    family of commands that involve reading many tree objects.
    In addition, traversing revisions while filtering changes
    with pathspecs is made faster by terminating the comparison
    between the trees as early as possible.


* Hooks

  - The part to send out notification e-mails was removed from
    the sample update hook, as it was not an appropriate place
    to do so.  The proper place to do this is the new post-receive
    hook.  An example hook has been added to contrib/hooks/.


* Others

  - git-revert, git-gc and git-cherry-pick are now built-ins.

Fixes since v1.5.0
------------------

These are all in v1.5.0.x series.

* Documentation updates

  - Clarifications and corrections to 1.5.0 release notes.

  - The main documentation did not link to git-remote documentation.

  - Clarified introductory text of git-rebase documentation.

  - Converted remaining mentions of update-index on Porcelain
    documents to git-add/git-rm.

  - Some i18n.* configuration variables were incorrectly
    described as core.*; fixed.

  - added and clarified core.bare, core.legacyheaders configurations.

  - updated "git-clone --depth" documentation.

  - user-manual updates.

  - Options to 'git remote add' were described insufficiently.

  - Configuration format.suffix was not documented.

  - Other formatting and spelling fixes.

  - user-manual has better cross references.

  - gitweb installation/deployment procedure is now documented.


* Bugfixes

  - git-upload-pack closes unused pipe ends; earlier this caused
    many zombies to hang around.

  - git-rerere was recording the contents of earlier hunks
    duplicated in later hunks.  This prevented resolving the same
    conflict when performing the same merge the other way around.

  - git-add and git-update-index on a filesystem on which
    executable bits are unreliable incorrectly reused st_mode
    bits even when the path changed between symlink and regular
    file.

  - git-daemon marks the listening sockets with FD_CLOEXEC so
    that it won't be leaked into the children.

  - segfault from git-blame when the mandatory pathname
    parameter was missing was fixed; usage() message is given
    instead.

  - git-rev-list did not read $GIT_DIR/config file, which means
    that did not honor i18n.logoutputencoding correctly.

  - Automated merge conflict handling when changes to symbolic
    links conflicted were completely broken.  The merge-resolve
    strategy created a regular file with conflict markers in it
    in place of the symbolic link.  The default strategy,
    merge-recursive was even more broken.  It removed the path
    that was pointed at by the symbolic link.  Both of these
    problems have been fixed.

  - 'git diff maint master next' did not correctly give combined
    diff across three trees.

  - 'git
