+Git v1.7.1 Release Notes (draft)
+================================
+
+Updates since v1.7.0
+--------------------
+
+ * Some commands (e.g. svn and http interfaces) that interactively ask
+ password can be told to use an external program given via GIT_ASKPASS.
+
+ * "git am" learned "--keep-cr" option to handle inputs that are
+ mixture of changes to files with and without CRLF line endings.
+
+ * "git cvsimport" learned -R option to leave revision mapping between
+ CVS revisions and resulting git commits.
+
+ * "git diff --submodule" notices and descries dirty submodules.
+
+ * "git for-each-ref" learned %(symref), %(symref:short) and %(flag)
+ tokens.
+
+ * "git hash-object --stdin-paths" can take "--no-filters" option now.
+
+ * "git init" can be told to look at init.templatedir configuration
+ variable (obviously that has to come from either /etc/gitconfig or
+ $HOME/.gitconfig).
+
+ * "git grep" learned "--no-index" option, to search inside contents that
+ are not managed by git.
+
+ * "git grep" learned --color=auto/always/never.
+
+ * "git grep" learned to paint filename and line-number in colors.
+
+ * "git log -p --first-parent -m" shows one-parent diff for merge
+ commits, instead of showing combined diff.
+
+ * "git merge-file" learned to use custom conflict marker size and also use
+ the "union merge" behaviour.
+
+ * "git notes" command has been rewritten in C and learned quite a
+ many commands and features to help you carry notes forward across
+ rebases and amends.
+
+ * "git request-pull" identifies the commit the request is relative to in
+ a more readable way.
+
+ * "git reset" learned "--keep" option that lets you discard commits
+ near the tip while preserving your local changes in a way similar
+ to how "git checkout branch" does.
+
+ * "git status" notices and descries dirty submodules.
+
+ * "git svn" should work better when interacting with repositories
+ with CRLF line endings.
+
+ * "git imap-send" learned to support CRAM-MD5 authentication.
+
+Fixes since v1.7.0
+------------------
+
+All of the fixes in v1.7.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git add frotz/nitfol" did not complain when the entire frotz/ directory
+ was ignored.

executed from the top-level directory of a repository, which may
not necessarily be the current directory.
+am.keepcr::
+ If true, git-am will call git-mailsplit for patches in mbox format
+ with parameter '--keep-cr'. In this case git-mailsplit will
+ not remove `\r` from lines ending with `\r\n`. Can be overrriden
+ by giving '--no-keep-cr' from the command line.
+ See linkgit:git-am[1], linkgit:git-mailsplit[1].
+
apply.ignorewhitespace::
When set to 'change', tells 'git apply' to ignore changes in
whitespace, in the same way as the '--ignore-space-change'
`never`), never. When set to `true` or `auto`, use color only
when the output is written to the terminal. Defaults to `false`.

color.interactive::
When set to `always`, always use colors for interactive prompts
The configuration variables in the 'imap' section are described
in linkgit:git-imap-send[1].
+init.templatedir::
+ Specify the directory from which templates will be copied.
+ (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
+
instaweb.browser::
Specify the program that will be used to browse your working
repository in gitweb. See linkgit:git-instaweb[1].
mergetool.prompt::
Prompt before each invocation of the merge resolution program.
+notes.displayRef::
+ The (fully qualified) refname from which to show notes when
+ showing commit messages. The value of this variable can be set
+ to a glob, in which case notes from all matching refs will be
+ shown. You may also specify this configuration variable
+ several times. A warning will be issued for refs that do not
+ exist, but a glob that does not match any refs is silently
+ ignored.
++
+This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
+environment variable, which must be a colon separated list of refs or
+globs.
++
+The effective value of "core.notesRef" (possibly overridden by
+GIT_NOTES_REF) is also implicitly added to the list of refs to be
+displayed.
+
+notes.rewrite.<command>::
+ When rewriting commits with <command> (currently `amend` or
+ `rebase`) and this variable is set to `true`, git
+ automatically copies your notes from the original to the
+ rewritten commit. Defaults to `true`, but see
+ "notes.rewriteRef" below.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
+environment variable, which must be a colon separated list of refs or
+globs.
+
+notes.rewriteMode::
+ When copying notes during a rewrite (see the
+ "notes.rewrite.<command>" option), determines what to do if
+ the target commit already has a note. Must be one of
+ `overwrite`, `concatenate`, or `ignore`. Defaults to
+ `concatenate`.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
+environment variable.
+
+notes.rewriteRef::
+ When copying notes during a rewrite, specifies the (fully
+ qualified) ref whose notes should be copied. The ref may be a
+ glob, in which case notes in all matching refs will be copied.
+ You may also specify this configuration several times.

DESCRIPTION
-----------
-This command allows you to add notes to commit messages, without
-changing the commit. To discern these notes from the message stored
-in the commit object, the notes are indented like the message, after
-an unindented line saying "Notes:".
+This command allows you to add/remove notes to/from objects, without
+changing the objects themselves.
+
+A typical use of notes is to extend a commit message without having
+to change the commit itself. Such commit notes can be shown by `git log`
+along with the original commit message. To discern these notes from the
+message stored in the commit object, the notes are indented like the
+message, after an unindented line saying "Notes (<refname>):" (or
+"Notes:" for the default setting).
-To disable commit notes, you have to set the config variable
-core.notesRef to the empty string. Alternatively, you can set it
-to a different ref, something like "refs/notes/bugzilla". This setting
-can be overridden by the environment variable "GIT_NOTES_REF".
+This command always manipulates the notes specified in "core.notesRef"
+(see linkgit:git-config[1]), which can be overridden by GIT_NOTES_REF.
+To change which notes are shown by 'git-log', see the
+"notes.displayRef" configuration.
+
+See the description of "notes.rewrite.<command>" in
+linkgit:git-config[1] for a way of carrying your notes across commands
+that rewrite commits.

+ List the notes object for a given object. If no object is
+ given, show a list of all note objects and the objects they
+ annotate (in the format "<note object> <annotated object>").
+ This is the default subcommand if no subcommand is given.
+
+add::
+ Add notes for a given object (defaults to HEAD). Abort if the
+ object already has notes (use `-f` to overwrite an
+ existing note).
+
+copy::
+ Copy the notes for the first object onto the second object.
+ Abort if the second object already has notes, or if the first
+ object has none (use -f to overwrite existing notes to the
+ second object). This subcommand is equivalent to:
+ `git notes add [-f] -C $(git notes list <from-object>) <to-object>`
++
+In `\--stdin` mode, take lines in the format
++
+----------
+<from-object> SP <to-object> [ SP <rest> ] LF
+----------
++
+on standard input, and copy the notes from each <from-object> to its
+corresponding <to-object>. (The optional `<rest>` is ignored so that
+the command can read the input given to the `post-rewrite` hook.)
+
+append::
+ Append to the notes of an existing object (defaults to HEAD).
+ Creates a new notes object if needed.
+
edit::
- Edit the notes for a given commit (defaults to HEAD).
+ Edit the notes for a given object (defaults to HEAD).
show::
- Show the notes for a given commit (defaults to HEAD).
+ Show the notes for a given object (defaults to HEAD).
+
+remove::
+ Remove the notes for a given object (defaults to HEAD).
+ This is equivalent to specifying an empty note message to
+ the `edit` subcommand.
+prune::
+ Remove all notes for non-existing/unreachable objects.
OPTIONS
-------
+-f::
+--force::
+ When adding notes to an object that already has notes,
+ overwrite the existing notes (instead of aborting).
+
-m <msg>::
+--message=<msg>::
Use the given note message (instead of prompting).
- If multiple `-m` (or `-F`) options are given, their
- values are concatenated as separate paragraphs.
+ If multiple `-m` options are given, their values
+ are concatenated as separate paragraphs.
-F <file>::
+--file=<file>::
Take the note message from the given file. Use '-' to
read the note message from the standard input.
- If multiple `-F` (or `-m`) options are given, their
- values are concatenated as separate paragraphs.
+
+-C <object>::
+--reuse-message=<object>::
+ Reuse the note message from the given note object.
+
+-c <object>::
+--reedit-message=<object>::
+ Like '-C', but with '-c' the editor is invoked, so that
+ the user can further edit the note message.
+
+--ref <ref>::
+ Manipulate the notes tree in <ref>. This overrides both
+ GIT_NOTES_REF and the "core.notesRef" configuration. The ref
+ is taken to be in `refs/notes/` if it is not qualified.
+
+
+NOTES
+-----
+
+Every notes change creates a new commit at the specified notes ref.
+You can therefore inspect the history of the notes by invoking, e.g.,
+`git log -p notes/commits`.
+
+Currently the commit message only records which operation triggered
+the update, and the commit authorship is determined according to the
+usual rules (see linkgit:git-commit[1]). These details may change in
+the future.

and updates the files that are different between the named commit
and the current commit in the working tree.
+--keep::
+ Reset the index to the given commit, keeping local changes in
+ the working tree since the current commit, while updating
+ working tree files without local changes to what appears in
+ the given commit. If a file that is different between the
+ current commit and the given commit has local changes, reset
+ is aborted.

"reset --merge" is meant to be used when resetting out of a conflicted
merge. Any mergy operation guarantees that the work tree file that is
resetting out from a state that a mergy operation left after failing
with a conflict. That is why we disallow --merge option in this case.
+"reset --keep" is meant to be used when removing some of the last
+commits in the current branch while keeping changes in the working
+tree. If there could be conflicts between the changes in the commit we
+want to remove and the changes in the working tree we want to keep,
+the reset is disallowed. That's why it is disallowed if there are both
+changes between the working tree and HEAD, and between HEAD and the
+target. To be safe, it is also disallowed when there are unmerged
+entries.
+
The following tables show what happens when there are unmerged
entries:
--mixed X B B
--hard B B B
--merge B B B
+ --keep (disallowed)
working index HEAD target working index HEAD
----------------------------------------------------
--mixed X A A
--hard A A A
--merge A A A
+ --keep (disallowed)
X means any state and U means an unmerged index.
<2> This commits all other changes in the index.
<3> Adds the file to the index again.
+Keep changes in working tree while discarding some previous commits::
++
+Suppose you are working on something and you commit it, and then you
+continue working a bit more, but now you think that what you have in
+your working tree should be in another branch that has nothing to do
+with what you commited previously. You can start a new branch and
+reset it while keeping the changes in your work tree.
++
+------------
+$ git tag start
+$ git checkout -b branch1
+$ edit
+$ git commit ... <1>
+$ edit
+$ git checkout -b branch2 <2>
+$ git reset --keep start <3>
+------------
++
+<1> This commits your first edits in branch1.
+<2> In the ideal world, you could have realized that the earlier
+ commit did not belong to the new topic when you created and switched
+ to branch2 (i.e. "git checkout -b branch2 start"), but nobody is
+ perfect.
+<3> But you can use "reset --keep" to remove the unwanted commit after
+ you switched to "branch2".

Color the status sign (one of these: `*` `!` `+` `-`) of each commit
corresponding to the branch it's in.

--no-color::
Turn off colored output, even when the configuration file gives the
default to color output.
+ Same as `--color=never`.
Note that --more, --list, --independent and --merge-base options
are mutually exclusive.

exiting with non-zero status from this script causes the 'git gc --auto'
to abort.
+post-rewrite
+~~~~~~~~~~~~
+
+This hook is invoked by commands that rewrite commits (`git commit
+--amend`, 'git-rebase'; currently 'git-filter-branch' does 'not' call
+it!). Its first argument denotes the command it was invoked by:
+currently one of `amend` or `rebase`. Further command-dependent
+arguments may be passed in the future.
+
+The hook receives a list of the rewritten commits on stdin, in the
+format
+
+ <old-sha1> SP <new-sha1> [ SP <extra-info> ] LF
+
+The 'extra-info' is again command-dependent. If it is empty, the
+preceding SP is also omitted. Currently, no commands pass any
+'extra-info'.
+
+The hook always runs after the automatic note copying (see
+"notes.rewrite.<command>" in linkgit:git-config.txt) has happened, and
+thus has access to these notes.
+
+The following command-specific comments apply:
+
+rebase::
+ For the 'squash' and 'fixup' operation, all commits that were
+ squashed are listed as being rewritten to the squashed commit.
+ This means that there will be several lines sharing the same
+ 'new-sha1'.
++
+The commits are guaranteed to be listed in the order that they were
+processed by rebase.
+
+There is no default 'post-rewrite' hook, but see the
+`post-receive-copy-notes` script in `contrib/hooks` for an example
+that copies your git-notes to the rewritten commits.

- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a

- * want "git checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- * find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
- *
- * or:
- *
- * find . -name '*.h' -print0 | git checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,
