Git v1.6.6 Release Notes (draft)
================================

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, 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 use 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 transtion period, and ended up panicking on the day
their sysadmins updated their git installation.  We tried very hard to
avoid repeating that unpleasantness.

For changes decided to be in 1.7.0, we have been much louder to strongly
discourage such procrastination.  If you have been using recent versions
of git, you would have already seen warnings issued when you exercised
features whose behaviour will change, with the instruction on how to
keep the existing behaviour if you want to.  You hopefully should be
well prepared already.

Of course, we have also given "this and that will change in 1.7.0;
prepare yourselves" warnings in the release notes and announcement
messages.  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 them
  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
  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 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
  ammount 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 git-gui updates including new translations, wm states, etc.

* 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.

* The ancient "git merge <message> HEAD <branch>..." syntax will be
  removed in later versions of git.  A warning is given and tells
  users to use the "git merge -m <message> <branch>..." instead.

* "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.

* "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.

Fixes since v1.6.5
------------------

All of the fixes in v1.6.5.X maintenance series are included in this
release, unless otherwise noted.

* Enumeration of available merge strategies iterated over the list of
  commands in a wrong way, sometimes producing an incorrect result.
  Will backport by merging ed87465 (builtin-merge.c: call
  exclude_cmds() correctly., 2009-11-25).

* "git format-patch revisions... -- path" issued an incorrect error
  message that suggested to use "--" on the command line when path
  does not exist in the current work tree (it is a separate matter if
  it makes sense to limit format-patch with pathspecs like that
  without using the --full-diff option).  Will backport by merging
  7e93d3b (format-patch: add test for parsing of "--", 2009-11-26).

* "git shortlog" did not honor the "encoding" header embedded in the
  commit object like "git log" did.  Will backport by merging 79f7ca0
  (shortlog: respect commit encoding, 2009-11-25).
