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.
+
(performance)
+* many uses of lstat(2) in the codepath for "git checkout" have been
+ optimized out.
+
+* pruning reflog entries that are unreachable from the tip of the ref
+ during "git reflog prune" (hence "git gc") was very inefficient.
+
(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.
+
+* @{-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-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-fast-export choked when seeing a tag that does not point at commit.
+
+* 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.
Fixes since v1.6.2
------------------
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-checkout <tree-ish> <submodule>" did not update the index entry at
+ the named path; it now does.
+
+* git-gc spent excessive amount of time to decide if an object appears
+ in a locally existing pack (if needed, backport by merging 69e020a).
+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+ deciding to descend into a subdirectory but they did not match the
+ individual paths correctly. This caused pathspecs "abc/d ab" to match
+ "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+ and then "ab" incorrectly matched "abc/0" when it shouldn't).
+
+* "git-merge-recursive" was broken when a submodule entry was involved in
+ a criss-cross merge situation.
