-Git v1.6.6 Release Notes
-========================
-
-Notes on behaviour change
--------------------------
-
- * In this release, "git fsck" defaults to "git fsck --full" and
-   checks packfiles, and because of this it will take much longer to
-   complete than before.  If you prefer a quicker check only on loose
-   objects (the old default), you can say "git fsck --no-full".  This
-   has been supported by 1.5.4 and newer versions of git, so it is
-   safe to write it in your script even if you use slightly older git
-   on some of your machines.
-
-Preparing yourselves for compatibility issues in 1.7.0
-------------------------------------------------------
-
-In git 1.7.0, which is planned to be the release after 1.6.6, there will
-be a handful of behaviour changes that will break backward compatibility.
-
-These changes were discussed long time ago and existing behaviours have
-been identified as more problematic to the userbase than keeping them for
-the sake of backward compatibility.
-
-When necessary, a transition strategy for existing users has been designed
-not to force them running around setting configuration variables and
-updating their scripts in order to either keep the traditional behaviour
-or adjust to the new behaviour, on the day their sysadmin decides to install
-the new version of git.  When we switched from "git-foo" to "git foo" in
-1.6.0, even though the change had been advertised and the transition
-guide had been provided for a very long time, the users procrastinated
-during the entire transition period, and ended up panicking on the day
-their sysadmins updated their git installation.  We are trying to avoid
-repeating that unpleasantness in the 1.7.0 release.
-
-For changes decided to be in 1.7.0, commands that will be affected
-have been much louder to strongly discourage such procrastination, and
-they continue to be in this release.  If you have been using recent
-versions of git, you would have seen warnings issued when you used
-features whose behaviour will change, with a clear instruction on how
-to keep the existing behaviour if you want to.  You hopefully are
-already well prepared.
-
-Of course, we have also been giving "this and that will change in
-1.7.0; prepare yourselves" warnings in the release notes and
-announcement messages for the past few releases.  Let's see how well
-users will fare this time.
-
- * "git push" into a branch that is currently checked out (i.e. pointed by
-   HEAD in a repository that is not bare) will be 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.  Versions of git
-   since 1.6.2 have issued a loud warning when you tried to do these
-   operations without setting the configuration, so repositories of
-   people who still need to be able to perform such a push should
-   already have been future proofed.
-
-   Please refer to:
-
-   http://git.or.cz/gitwiki/GitFaq#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 process that already took place so far.
-
- * "git send-email" will 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.  Git 1.6.6 (this
-   release) will issue a warning about the upcoming default change, when
-   it uses the traditional "deep threading" behaviour as the built-in
-   default.  To squelch the warning but still use the "deep threading"
-   behaviour, give --chain-reply-to option or set sendemail.chainreplyto
-   to true.
-
-   It has been possible to configure send-email to send "shallow thread"
-   by setting sendemail.chainreplyto configuration variable to false.
-   The only thing 1.7.0 release will do is to change the default when
-   you haven't configured that variable.
-
- * "git status" will not be "git commit --dry-run".  This change does not
-   affect you if you run the command without pathspec.
-
-   Nobody sane found the current behaviour of "git status Makefile" useful
-   nor meaningful, and it confused users.  "git commit --dry-run" has been
-   provided as a way to get the current behaviour of this command since
-   1.6.5.
-
- * "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
-   amount of whitespace and nothing else.  and "git diff -b" showed the
-   "diff --git" header line for such a change without patch text.
-
-   In 1.7.0, the "ignore whitespaces" will affect the semantics of the
-   diff operation itself.  A change that does not affect anything but
-   whitespaces will be reported with zero exit status when run with
-   --exit-code, and there will not be "diff --git" header for such a
-   change.
-
-
-Updates since v1.6.5
---------------------
-
-(subsystems)
-
- * various gitk updates including use of themed widgets under Tk 8.5,
-   Japanese translation, a fix to a bug when running "gui blame" from
-   a subdirectory, etc.
-
- * various git-gui updates including new translations, wm states fixes,
-   Tk bug workaround after quitting, improved heuristics to trigger gc,
-   etc.
-
- * various git-svn updates.
-
- * "git fetch" over http learned a new mode that is different from the
-   traditional "dumb commit walker".
-
-(portability)
-
- * imap-send can be built on mingw port.
-
-(performance)
-
- * "git diff -B" has smaller memory footprint.
-
-(usability, bells and whistles)
-
- * The object replace mechanism can be bypassed with --no-replace-objects
-   global option given to the "git" program.
-
- * In configuration files, a few variables that name paths can begin with ~/
-   and ~username/ and they are expanded as expected.
-
- * "git subcmd -h" now shows short usage help for many more subcommands.
-
- * "git bisect reset" can reset to an arbitrary commit.
-
- * "git checkout frotz" when there is no local branch "frotz" but there
-   is only one remote tracking branch "frotz" is taken as a request to
-   start the named branch at the corresponding remote tracking branch.
-
- * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
-   to ignore authorship information in the commit it is taking the message
-   from.
-
- * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
-
- * "git diff" learned --submodule option to show a list of one-line logs
-   instead of differences between the commit object names.
-
- * "git diff" learned to honor diff.color.func configuration to paint
-   function name hint printed on the hunk header "@@ -j,k +l,m @@" line
-   in the specified color.
-
- * "git fetch" learned --all and --multiple options, to run fetch from
-   many repositories, and --prune option to remove remote tracking
-   branches that went stale.  These make "git remote update" and "git
-   remote prune" less necessary (there is no plan to remove "remote
-   update" nor "remote prune", though).
-
- * "git fsck" by default checks the packfiles (i.e. "--full" is the
-   default); you can turn it off with "git fsck --no-full".
-
- * "git grep" can use -F (fixed strings) and -i (ignore case) together.
-
- * import-tars contributed fast-import frontend learned more types of
-   compressed tarballs.
-
- * "git instaweb" knows how to talk with mod_cgid to apache2.
-
- * "git log --decorate" shows the location of HEAD as well.
-
- * "git log" and "git rev-list" learned to take revs and pathspecs from
-   the standard input with the new "--stdin" option.
-
- * "--pretty=format" option to "log" family of commands learned:
-
-   . to wrap text with the "%w()" specifier.
-   . to show reflog information with "%g[sdD]" specifier.
-
- * "git notes" command to annotate existing commits.
-
- * "git merge" (and "git pull") learned --ff-only option to make it fail
-   if the merge does not result in a fast-forward.
-
- * "git mergetool" learned to use p4merge.
-
- * "git rebase -i" learned "reword" that acts like "edit" but immediately
-   starts an editor to tweak the log message without returning control to
-   the shell, which is done by "edit" to give an opportunity to tweak the
-   contents.
-
- * "git send-email" can be told with "--envelope-sender=auto" to use the
-   same address as "From:" address as the envelope sender address.
-
- * "git send-email" will issue a warning when it defaults to the
-   --chain-reply-to behaviour without being told by the user and
-   instructs to prepare for the change of the default in 1.7.0 release.
-
- * In "git submodule add <repository> <path>", <path> is now optional and
-   inferred from <repository> the same way "git clone <repository>" does.
-
- * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
-
- * "git svn" learned to recreate empty directories tracked only by SVN.
-
- * "gitweb" can optionally render its "blame" output incrementally (this
-   requires JavaScript on the client side).
-
- * Author names shown in gitweb output are links to search commits by the
-   author.
