-Git v1.7.0 Release Notes
-========================
-
-Notes on behaviour change
--------------------------
-
- * "git push" into a branch that is currently checked out (i.e. pointed at by
-   HEAD in a repository that is not bare) is 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.
-
- * "git send-email" does 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.
-
-   It has been possible already to configure send-email to send "shallow thread"
-   by setting sendemail.chainreplyto configuration variable to false.  The
-   only thing this release does is to change the default when you haven't
-   configured that variable.
-
- * "git status" is not "git commit --dry-run" anymore.  This change does
-   not affect you if you run the command without argument.
-
- * "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 this release, the "ignore whitespaces" options affect the semantics
-   of the diff operation.  A change that does not affect anything but
-   whitespaces is reported with zero exit status when run with
-   --exit-code, and there is no "diff --git" header for such a change.
-
- * External diff and textconv helpers are now executed using the shell.
-   This makes them consistent with other programs executed by git, and
-   allows you to pass command-line parameters to the helpers. Any helper
-   paths containing spaces or other metacharacters now need to be
-   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
-   environment, and diff.*.command and diff.*.textconv in the config
-   file.
-
- * The --max-pack-size argument to 'git repack', 'git pack-objects', and
-   'git fast-import' was assuming the provided size to be expressed in MiB,
-   unlike the corresponding config variable and other similar options accepting
-   a size value.  It is now expecting a size expressed in bytes, with a possible
-   unit suffix of 'k', 'm', or 'g'.
-
-Updates since v1.6.6
---------------------
-
-(subsystems)
-
- * "git fast-import" updates; adds "option" and "feature" to detect the
-   mismatch between fast-import and the frontends that produce the input
-   stream.
-
- * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
-
- * "gitk" and "git gui" translation updates.
-
- * "gitweb" updates (code clean-up, load checking etc.)
-
-(portability)
-
- * Some more MSVC portability patches for msysgit port.
-
- * Minimum Pthreads emulation for msysgit port.
-
-(performance)
-
- * More performance improvement patches for msysgit port.
-
-(usability, bells and whistles)
-
- * More commands learned "--quiet" and "--[no-]progress" options.
-
- * Various commands given by the end user (e.g. diff.type.textconv,
-   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
-   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
-
- * "sparse checkout" feature allows only part of the work tree to be
-   checked out.
-
- * HTTP transfer can use authentication scheme other than basic
-   (i.e./e.g. digest).
-
- * Switching from a version of superproject that used to have a submodule
-   to another version of superproject that no longer has it did not remove
-   the submodule directory when it should (namely, when you are not
-   interested in the submodule at all and didn't clone/checkout).
-
- * A new attribute conflict-marker-size can be used to change the size of
-   the conflict markers from the default 7; this is useful when tracked
-   contents (e.g. git-merge documentation) have strings that resemble the
-   conflict markers.
-
- * A new syntax "<branch>@{upstream}" can be used on the command line to
-   substitute the name of the "upstream" of the branch.  Missing branch
-   defaults to the current branch, so "git fetch && git merge @{upstream}"
-   will be equivalent to "git pull".
-
- * "git am --resolved" has a synonym "git am --continue".
-
- * "git branch --set-upstream" can be used to update the (surprise!) upstream,
-   i.e. where the branch is supposed to pull and merge from (or rebase onto).
-
- * "git checkout A...B" is a way to detach HEAD at the merge base between
-   A and B.
-
- * "git checkout -m path" to reset the work tree file back into the
-   conflicted state works even when you already ran "git add path" and
-   resolved the conflicts.
-
- * "git commit --date='<date>'" can be used to override the author date
-   just like "git commit --author='<name> <email>'" can be used to
-   override the author identity.
-
- * "git commit --no-status" can be used to omit the listing of the index
-   and the work tree status in the editor used to prepare the log message.
-
- * "git commit" warns a bit more aggressively until you configure user.email,
-   whose default value almost always is not (and fundamentally cannot be)
-   what you want.
-
- * "git difftool" has been extended to make it easier to integrate it
-   with gitk.
-
- * "git fetch --all" can now be used in place of "git remote update".
-
- * "git grep" does not rely on external grep anymore.  It can use more than
-   one thread to accelerate the operation.
-
- * "git grep" learned "--quiet" option.
-
- * "git log" and friends learned "--glob=heads/*" syntax that is a more
-   flexible way to complement "--branches/--tags/--remotes".
-
- * "git merge" learned to pass options specific to strategy-backends.  E.g.
-
-    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
-      strategy how much to shift the trees explicitly.
-
-    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
-      while discarding your own changes and taking merged version in
-      conflicted regions.
-
- * "git push" learned "git push origin --delete branch", a syntactic sugar
-   for "git push origin :branch".
-
- * "git push" learned "git push --set-upstream origin forker:forkee" that
-   lets you configure your "forker" branch to later pull from "forkee"
-   branch at "origin".
-
- * "git rebase --onto A...B" means the history is replayed on top of the
-   merge base between A and B.
-
- * "git rebase -i" learned new action "fixup" that squashes the change
-   but does not affect existing log message.
-
- * "git rebase -i" also learned --autosquash option that is useful
-   together with the new "fixup" action.
-
- * "git remote" learned set-url subcommand that updates (surprise!) url
-   for an existing remote nickname.
-
- * "git rerere" learned "forget path" subcommand.  Together with "git
-   checkout -m path" it will be useful when you recorded a wrong
-   resolution.
-
- * Use of "git reset --merge" has become easier when resetting away a
-   conflicted mess left in the work tree.
-
- * "git rerere" had rerere.autoupdate configuration but there was no way
-   to countermand it from the command line; --no-rerere-autoupdate option
-   given to "merge", "revert", etc. fixes this.
-
- * "git status" learned "-s(hort)" output format.
-
-(developers)
-
- * The infrastructure to build foreign SCM interface has been updated.
-
- * Many more commands are now built-in.
-
- * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
-   compression will always take advantage of it.
-
-Fixes since v1.6.6
-------------------
-
-All of the fixes in v1.6.6.X maintenance series are included in this
-release, unless otherwise noted.
-
- * "git branch -d branch" used to refuse deleting the branch even when
-   the branch is fully merged to its upstream branch if it is not merged
-   to the current branch.  It now deletes it in such a case.
-
- * "filter-branch" command incorrectly said --prune-empty and --filter-commit
-   were incompatible; the latter should be read as --commit-filter.
-
- * When using "git status" or asking "git diff" to compare the work tree
-   with something, they used to consider that a checked-out submodule with
-   uncommitted changes is not modified; this could cause people to forget
-   committing these changes in the submodule before committing in the
-   superproject. They now consider such a change as a modification and
-   "git diff" will append a "-dirty" to the work tree side when generating
-   patch output or when used with the --submodule option.
