[ANNOUNCE] GIT 1.2.0

[Junio C Hamano <junkio@cox.net>]

A resend.  I am suspecting vger does not want two lists hosted
there both named on To: line...

-- >8 --
The latest feature release GIT 1.2.0 is available at the
usual places:

	http://www.kernel.org/pub/software/scm/git/

	git-1.2.0.tar.{gz,bz2}			(tarball)
	RPMS/$arch/git-*-1.2.0-1.$arch.rpm	(RPM)

Right now binary RPM is available only for x86_64, because I do
not have an access to RPM capable i386 box.


What's new in 1.2.0

The new release 1.2.0 took about one month since 1.1.0 was released.
It has literally _tons_ of updates since the last maintenance release
1.1.6.  While people who have been following the master branch are
probably familiar with most of them, I expect others would be quite
surprised by the amount of changes.  Hopefully the surprise is of a
pleasant kind.

Here is the list of all the good stuff (not counting what are
already in the 1.1.X maintenance series).

* Major features

 - Checkout -m option.  This allows you to switch branches when
   you have local changes to paths that are different in the
   current branch and new branch.  The local changes are merged to
   the version from the branch you are switching to and the merge
   result is left in your working tree (you may see conflicts).

 - Add -c and --cc to diff-tree and diff-files.  They give the
   "combined diff" output that shows merges more human readably,
   and the "git diff" wrapper uses --cc by default.  This release
   also comes with updated gitk (Paul Mackerras) that takes advantage
   of this feature.

 - git-commit updates.

   - Allow git-commit from a subdirectory.

   - Aborted "git-commit -a" leaves the index as it was.

   - "git commit --only paths..." checks in changes to only
     named paths.

     This will become the default, instead of the traditional
     --include semantics, during development track towards
     1.3.0, so if you are used to the --include semantics,
     please start training your fingers to explicitly say
     "git commit --include paths...".

   - Add --author='A U Thor <author@example.com>' command
     line option.

   - "git commit -v" seeds the end of the commit log message editor
     with the patch to be committed.

 - git-status updates.  Now it takes the exactly same set of parameters
   as git-commit takes, and serves as a way to preview what you would
   be committing.  The -v option to get diff output is also available.
