 +GIT v1.6.3 Release Notes
 +========================
 +
 +With the next major release, "git push" into a branch that is
 +currently checked out will be refused by default.  You can choose
 +what should happen upon such a push by setting the configuration
 +variable receive.denyCurrentBranch in the receiving repository.
 +
 +To ease the transition plan, the receiving repository of such a
 +push running this release will issue a big warning when the
 +configuration variable is missing.  Please refer to:
 +
 +  http://git.or.cz/gitwiki/GitFaq#non-bare
 +  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
 +
 +for more details on the reason why this change is needed and the
 +transition plan.
 +
 +For a similar reason, "git push $there :$killed" to delete the branch
 +$killed in a remote repository $there, if $killed branch is the current
 +branch pointed at by its HEAD, gets a large warning.  You can choose what
 +should happen upon such a push by setting the configuration variable
 +receive.denyDeleteCurrent in the receiving repository.
 +
 +When the user does not tell "git push" what to push, it has always
 +pushed matching refs.  For some people it is unexpected, and a new
 +configuration variable push.default has been introduced to allow
 +changing a different default behaviour.  To advertise the new feature,
 +a big warning is issued if this is not configured and a git push without
 +arguments is attempted.
 +
 +
 +Updates since v1.6.2
 +--------------------
 +
 +(subsystems)
 +
 +(performance)
 +
 +* many uses of lstat(2) in the codepath for "git checkout" have been
 +  optimized out.
 +
 +(usability, bells and whistles)
 +
 +* rsync:/path/to/repo can be used to run git over rsync for local
 +  repositories.  It may not be useful in practice; meant primarily for
 +  testing.
 +
 +* http transport learned to prompt and use password when fetching from or
 +  pushing to http://user@host.xz/ URL.
 +
 +* (msysgit) progress output that is sent over the sideband protocol can
 +  be handled appropriately in Windows console.
 +
 +* "--pretty=<style>" option to the log family of commands can now be
 +  spelled as "--format=<style>".  In addition, --format=%formatstring
 +  is a short-hand for --pretty=tformat:%formatstring.
 +
 +* "--oneline" is a synonym for "--pretty=oneline --abbrev=commit".
 +
 +* If you realize that you botched the patch when you are editing hunks
 +  with the 'edit' action in git-add -i/-p, you can abort the editor to
 +  tell git not to apply it.
 +
 +* The number of commits shown in "you are ahead/behind your upstream"
 +  messages given by "git checkout" and "git status" used to count merge
 +  commits; now it doesn't.
 +
 +* git-archive learned --output=<file> option.
 +
 +* git-bisect shows not just the number of remaining commits whose goodness
 +  is unknown, but also shows the estimated number of remaining rounds.
 +
 +* You can give --date=<format> option to git-blame.
 +
 +* git-branch -r shows HEAD symref that points at a remote branch in
 +  interest of each tracked remote repository.
 +
 +* git-config learned -e option to open an editor to edit the config file
 +  directly.
 +
 +* git-clone runs post-checkout hook when run without --no-checkout.
 +
 +* git-fast-export choked when seeing a tag that does not point at commit.
 +
 +* git-format-patch can be told to use attachment with a new configuration,
 +  format.attach.
 +
 +* git-format-patch can be told to produce deep or shallow message threads.
 +
 +* git-format-patch learned format.headers configuration to add extra
 +  header fields to the output.  This behaviour is similar to the existing
 +  --add-header=<header> option of the command.
 +
 +* git-grep learned to highlight the found substrings in color.
 +
 +* git-imap-send learned to work around Thunderbird's inability to easily
 +  disable format=flowed with a new configuration, imap.preformattedHTML.
 +
 +* git-rebase can be told to rebase the series even if your branch is a
 +  descendant of the commit you are rebasing onto with --force-rebase
 +  option.
 +
 +* git-rebase can be told to report diffstat with the --stat option.
 +
 +* Output from git-remote command has been vastly improved.
 +
 +* git-send-email learned --confirm option to review the Cc: list before
 +  sending the messages out.
 +
 +(developers)
 +
 +* Test scripts can be run under valgrind.
 +
 +* Test scripts can be run with installed git.
 +
 +* Makefile learned 'coverage' option to run the test suites with
 +  coverage tracking enabled.
 +
 +* Building the manpages with docbook-xsl between 1.69.1 and 1.71.1 now
 +  requires setting DOCBOOK_SUPPRESS_SP to work around a docbook-xsl bug.
 +  This workaround used to be enabled by default, but causes problems
 +  with newer versions of docbook-xsl.  In addition, there are a few more
 +  knobs you can tweak to work around issues with various versions of the
 +  docbook-xsl package.  See comments in Documentation/Makefile for details.
 +
 +Fixes since v1.6.2
 +------------------
 +
 +All of the fixes in v1.6.2.X maintenance series are included in this
 +release, unless otherwise noted.
 +
 +Here are fixes that this release has, but have not been backported to
 +v1.6.2.X series.
 +
 +* The initial checkout did not read the attributes from the .gitattribute
 +  file that is being checked out.
 +
 +* git-gc spent excessive amount of time to decide if an object appears
 +  in a locally existing pack (if needed, backport by merging 69e020a).
