Git v1.8.0 Release Notes
========================

Backward compatibility notes
----------------------------

In the next major release (not *this* one), we will change the
behavior of the "git push" command.

When "git push [$there]" does not say what to push, we have used the
traditional "matching" semantics so far (all your branches were sent
to the remote as long as there already are branches of the same name
over there).  We will use the "simple" semantics that pushes the
current branch to the branch with the same name, only when the current
branch is set to integrate with that remote branch.  There is a user
preference configuration variable "push.default" to change this, and
"git push" will warn about the upcoming change until you set this
variable in this release.

"git branch --set-upstream" is deprecated and may be removed in a
relatively distant future.  "git branch [-u|--set-upstream-to]" has
been introduced with a saner order of arguments.


Updates since v1.7.12
---------------------

UI, Workflows & Features

 * A credential helper for Win32 to allow access to the keychain of
   the logged-in user has been added.

 * An initial port to HP NonStop.

 * A credential helper to allow access to the Gnome keyring has been
   added.

 * When "git am" sanitizes the "Subject:" line, we strip the prefix from
   "Re: subject" and also from a less common "re: subject", but left
   the even less common "RE: subject" intact.  Now we strip that too.

 * It was tempting to say "git branch --set-upstream origin/master",
   but that tells Git to arrange the local branch "origin/master" to
   integrate with the currently checked out branch, which is highly
   unlikely what the user meant.  The option is deprecated; use the
   new "--set-upstream-to" (with a short-and-sweet "-u") option
   instead.

 * "git cherry-pick" learned the "--allow-empty-message" option to
   allow it to replay a commit without any log message.

 * After "git cherry-pick -s" gave control back to the user asking
   help to resolve conflicts, concluding "git commit" used to need to
   be run with "-s" if the user wants to sign it off; now the command
   leaves the sign-off line in the log template.

 * "git daemon" learned the "--access-hook" option to allow an
   external command to decline service based on the client address,
   repository path, etc.

 * "git difftool --dir-diff" learned to use symbolic links to prepare
   a temporary copy of the working tree when available.

 * "git grep" learned to use a non-standard pattern type by default if
   a configuration variable tells it to.

 * Accumulated updates to "git gui" has been merged.

 * "git log -g" learned the "--grep-reflog=<pattern>" option to limit
   its output to commits with a reflog message that matches the given
   pattern.

 * "git merge-base" learned the "--is-ancestor A B" option to tell if A is
   an ancestor of B.  The result is indicated by its exit status code.

 * "git mergetool" now allows users to override the actual command used
   with the mergetool.$name.cmd configuration variable even for built-in
   mergetool backends.

 * "git rebase -i" learned the "--edit-todo" option to open an editor
   to edit the instruction sheet.


Foreign Interface

 * "git svn" has been updated to work with SVN 1.7.

 * "git p4" learned the "--conflicts" option to specify what to do when
   encountering a conflict during "p4 submit".


Performance, Internal Implementation, etc.

 * Git ships with a fall-back regexp implementation for platforms with
   buggy regexp library, but it was easy for people to keep using their
   platform regexp by mistake.  A new test has been added to check this.

 * The "check-docs" build target has been updated and greatly
   simplified.

 * The test suite is run under MALLOC_CHECK_ when running with a glibc
   that supports the feature.

 * The documentation in the TeXinfo format was using indented output
   for materials meant to be examples that are better typeset in
