+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:
+
+  https://archive.kernel.org/oldwiki/git.wiki.kernel.org/index.php/GitFaq.html#non-bare
+  https://lore.kernel.org/git/7vbptlsuyv.fsf@gitster.siamese.dyndns.org/
+
+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)
+
+* various git-svn updates.
+
+* git-gui updates, including an update to Russian translation, and a
+  fix to an infinite loop when showing an empty diff.
+
+* gitk updates, including an update to Russian translation and improved Windows
+  support.
+
+(performance)
+
+* many uses of lstat(2) in the codepath for "git checkout" have been
+  optimized out.
+
+(usability, bells and whistles)
+
+* Boolean configuration variable yes/no can be written as on/off.
+
+* 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".
+
+* "--graph" to the "git log" family can draw the commit ancestry graph
+  in colors.
+
+* 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.
+
+* @{-1} is a new way to refer to the last branch you were on introduced in
+  1.6.2, but the initial implementation did not teach this to a few
+  commands.  Now the syntax works with "branch -m @{-1} newname".
+
+* git-archive learned --output=<file> option.
+
+* git-archive takes attributes from the tree being archived; strictly
+  speaking, this is an incompatible behaviour change, but is a good one.
+  Use --worktree-attributes option to allow it to read attributes from
+  the work tree as before (deprecated git-tar tree command always reads
+  attributes from the work tree).
+
+* 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-branch -v -v" is a new way to get list of names for branches and the
+  "upstream" branch for them.
+
+* 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-difftool is now part of the officially supported command, primarily
+  maintained by David Aguilar.
+
+* git-for-each-ref learned a new "upstream" token.
+
+* 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 can be told to always add sign-off with a configuration
+  variable.
+
+* 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-format-patch gives human readable names to the attached files, when
+  told to send patches as attachments.
+
+* 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 remote update --prune $remote" updates from the named remote and
+  then prunes stale tracking branches.
+
+* 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.
+
+* Support for building and testing a subset of git on a system without a
+  working perl has been improved.
+
+
+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.
+
+* "git-apply" rejected a patch that swaps two files (i.e. renames A to B
+  and B to A at the same time).  May need to be backported by cherry
+  picking d8c81df and then 7fac0ee).
+
+* 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).
