Git v1.7.0 Release Notes
========================

Notes on behaviour change
-------------------------

 * "git push" into a branch that is currently checked out (i.e. pointed by
   HEAD in a repository that is not bare) is refused by default.

   Similarly, "git push $there :$killed" to delete the branch $killed
   in a remote repository $there, when $killed branch is the current
   branch pointed at by its HEAD, will be refused by default.

   Setting the configuration variables receive.denyCurrentBranch and
   receive.denyDeleteCurrent to 'ignore' in the receiving repository
   can be used to override these safety features.

 * "git send-email" does not make deep threads by default when sending a
   patch series with more than two messages.  All messages will be sent
   as a reply to the first message, i.e. cover letter.

   It has been possible to configure send-email to send "shallow thread"
   by setting sendemail.chainreplyto configuration variable to false.  The
   only thing this release does is to change the default when you haven't
   configured that variable.

 * "git status" is not "git commit --dry-run" anymore.  This change does
   not affect you if you run the command without pathspec.

 * "git diff" traditionally treated various "ignore whitespace" options
   only as a way to filter the patch output.  "git diff --exit-code -b"
   exited with non-zero status even if all changes were about changing the
   ammount of whitespace and nothing else.  and "git diff -b" showed the
   "diff --git" header line for such a change without patch text.

   In this release, the "ignore whitespaces" options affect the semantics
   of the diff operation.  A change that does not affect anything but
   whitespaces is reported with zero exit status when run with
   --exit-code, and there is no "diff --git" header for such a change.


Updates since v1.6.6
--------------------

(subsystems)

 * "git fast-import" updates; adds "option" and "feature" to detect the
   mismatch between fast-import and the frontends that produce the input
   stream.

(portability)

 * Some more MSVC portability patches for msysgit port.

 * Minimum Pthreads emulation for msysgit port.

(performance)

 * More performance improvement patches for msysgit port.

(usability, bells and whistles)

 * More commands learned "--quiet" and "--[no-]progress" options.

 * Various commands given by the end user (e.g. diff.type.textconv,
   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
   is now possible to say "[diff "utf8doc"] textconv = nkf -w".

 * "sparse checkout" feature allows only part of the work tree to be
   checked out.

 * HTTP transfer can use authentication scheme other than basic
   (i.e./e.g. digest).

 * Switching from a version of superproject that used to have a submodule
   to another version of superproject that no longer has it did not remove
   the submodule directory when it should (namely, when you are not
   interested in the submodule at all and didn't clone/checkout).

 * "git checkout A...B" is a way to detach HEAD at the merge base between
   A and B.

 * "git commit --date='<date>'" can be used to override the author date
   just like "git commit --author='<name> <email>'" can be used to
   override the author identity.

 * "git commit --no-status" can be used to omit the listing of the index
   and the work tree status in the editor used to prepare the log message.

 * "git fetch --all" can now be used in place of "git remote update".

 * "git push" learned "git push origin --delete branch", a syntactic sugar
   for "git push origin :branch".

 * "git rebase --onto A...B" means the history is replayed on top of the
   merge base between A and B.

 * Use of "git reset --merge" has become easier when resetting away a
   conflicted mess left in the work tree.

 * "git rerere" had rerere.autoupdate configuration but there was no way
   to countermand it from the command line; --no-rerere-autoupdate option
   given to "merge", "revert", etc. fixes this.

 * "git status" learned "-s(hort)" output format.

(developers)

 * The infrastructure to build foreign SCM interface has been updated.
