+Git v1.9 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+"git submodule foreach $cmd $args" used to treat "$cmd $args" the same
+way "ssh" did, concatenating them into a single string and letting the
+shell unquote. Careless users who forget to sufficiently quote $args
+gets their argument split at $IFS whitespaces by the shell, and got
+unexpected results due to this. Starting from this release, the
+command line is passed directly to the shell, if it has an argument.
+
+Read-only support for experimental loose-object format, in which users
+could optionally choose to write in their loose objects for a short
+while between v1.4.3 to v1.5.3 era, has been dropped.
+
+The meanings of "--tags" option to "git fetch" has changed; the
+command fetches tags _in addition to_ what are fetched by the same
+command line without the option.
+
+The way "git push $there $what" interprets $what part given on the
+command line, when it does not have a colon that explicitly tells us
+what ref at the $there repository is to be updated, has been enhanced.
+
+A handful of ancient commands that have long been deprecated are
+finally gone (repo-config, tar-tree, lost-found, and peek-remote).
+
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there). In Git 2.0, the default will change to the "simple"
+semantics, which pushes:
+
+ - only the current branch to the branch with the same name, and only
+ when the current branch is set to integrate with that remote
+ branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+ are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this. If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour. If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands. There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes. A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal. Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0. For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.5
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * The HTTP transport, when talking GSS-Negotiate, uses "100
+ Continue" response to avoid having to rewind and resend a large
+ payload, which may not be always doable.
+
+ * Various bugfixes to remote-bzr and remote-hg (in contrib/).
+
+ * The build procedure is aware of MirBSD now.
+
+
+UI, Workflows & Features
+
+ * Fetching from a shallowly-cloned repository used to be forbidden,
+ primarily because the codepaths involved were not carefully vetted
+ and we did not bother supporting such usage. This release attempts
+ to allow object transfer out of a shallowly-cloned repository in a
+ more controlled way (i.e. the receiver become a shallow repository
+ with a truncated history).
+
+ * Just like we give a reasonable default for "less" via the LESS
+ environment variable, we now specify a reasonable default for "lv"
+ via the "LV" environment variable when spawning the pager.
+
+ * Two-level configuration variable names in "branch.*" and "remote.*"
+ hierarchies, whose variables are predominantly three-level, were
+ not completed by hitting a <TAB> in bash and zsh completions.
+
+ * Fetching 'frotz' branch with "git fetch", while 'frotz/nitfol'
+ remote-tracking branch from an earlier fetch was still there, would
+ error out, primarily because the command was not told that it is
+ allowed to lose any information on our side. "git fetch --prune"
+ now can be used to remove 'frotz/nitfol' to make room to fetch and
+ store 'frotz' remote-tracking branch.
+
+ * "diff.orderfile=<file>" configuration variable can be used to
+ pretend as if the "-O<file>" option were given from the command
+ line of "git diff", etc.
+
+ * The negative pathspec syntax allows "git log -- . ':!dir'" to tell
+ us "I am interested in everything but 'dir' directory".
+
+ * "git difftool" shows how many different paths there are in total,
+ and how many of them have been shown so far, to indicate progress.
+
+ * "git push origin master" used to push our 'master' branch to update
+ the 'master' branch at the 'origin' repository. This has been
+ enhanced to use the same ref mapping "git push origin" would use to
+ determine what ref at the 'origin' to be updated with our 'master'.
+ For example, with this configuration
+
+ [remote "origin"]
+ push = refs/heads/*:refs/review/*
+
+ that would cause "git push origin" to push out our local branches
+ to corresponding refs under refs/review/ hierarchy at 'origin',
+ "git push origin master" would update 'refs/review/master' over
+ there. Alternatively, if push.default is set to 'upstream' and our
+ 'master' is set to integrate with 'topic' from the 'origin' branch,
+ running "git push origin" while on our 'master' would update their
+ 'topic' branch, and running "git push origin master" while on any
+ of our branches does the same.
+
+ * "gitweb" learned to treat ref hierarchies other than refs/heads as
+ if they are additional branch namespaces (e.g. refs/changes/ in
+ Gerrit).
+
+ * "git for-each-ref --format=..." learned a few formatting directives;
+ e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
+
+ * The command string given to "git submodule foreach" is passed
+ directly to the shell, without being eval'ed. This is a backward
+ incompatible change that may break existing users.
+
+ * "git log" and friends learned the "--exclude=<glob>" option, to
+ allow people to say "list history of all branches except those that
+ match this pattern" with "git log --exclude='*/*' --branches".
+
+ * "git rev-parse --parseopt" learned a new "--stuck-long" option to
+ help scripts parse options with an optional parameter.
+
+ * The "--tags" option to "git fetch" no longer tells the command to
+ fetch _only_ the tags. It instead fetches tags _in addition to_
+ what are fetched by the same command line without the option.
+
+
+Performance, Internal Implementation, etc.
+
+ * When parsing a 40-hex string into the object name, the string is
+ checked to see if it can be interpreted as a ref so that a warning
+ can be given for ambiguity. The code kicked in even when the
+ core.warnambiguousrefs is set to false to squelch this warning, in
+ which case the cycles spent to look at the ref namespace were an
+ expensive no-op, as the result was discarded without being used.
+
+ * The naming convention of the packfiles has been updated; it used to
+ be based on the enumeration of names of the objects that are
+ contained in the pack, but now it also depends on how the packed
+ result is represented---packing the same set of objects using
+ different settings (or delta order) would produce a pack with
+ different name.
+
+ * "git diff --no-index" mode used to unnecessarily attempt to read
+ the index when there is one.
+
+ * The deprecated parse-options macro OPT_BOOLEAN has been removed;
+ use OPT_BOOL or OPT_COUNTUP in new code.
+
+ * A few duplicate implementations of prefix/suffix string comparison
+ functions have been unified to starts_with() and ends_with().
+
+ * The new PERLLIB_EXTRA makefile variable can be used to specify
+ additional directories Perl modules (e.g. the ones necessary to run
+ git-svn) are installed on the platform when building.
+
+ * "git merge-base" learned the "--fork-point" mode, that implements
+ the same logic used in "git pull --rebase" to find a suitable fork
+ point out of the reflog entries for the remote-tracking branch the
+ work has been based on. "git rebase" has the same logic that can be
+ triggered with the "--fork-point" option.
+
+ * A third-party "receive-pack" (the responder to "git push") can
+ advertise the "no-thin" capability to tell "git push" not to use
+ the thin-pack optimization. Our receive-pack has always been
+ capable of accepting and fattening a thin-pack, and will continue
+ not to ask "git push" to use a non-thin pack.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.5
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.5 in the maintenance
+track are contained in this release (see the maintenance releases' notes
+for details).
+
+ * "submodule.*.update=checkout", when propagated from .gitmodules to
+ .git/config, turned into a "submodule.*.update=none", which did not
+ make much sense.
+ (merge efa8fd7 fp/submodule-checkout-mode later to maint).
+
+ * The implementation of 'git stash $cmd "stash@{...}"' did not quote
+ the stash argument properly and left it split at IFS whitespace.
+ (merge 2a07e43 ow/stash-with-ifs later to maint).
+
+ * The "--[no-]informative-errors" options to "git daemon" were parsed
+ a bit too loosely, allowing any other string after these option
+ names.
+ (merge 82246b7 nd/daemon-informative-errors-typofix later to maint).
+
+ * There is no reason to have a hardcoded upper limit of the number of
+ parents for an octopus merge, created via the graft mechanism, but
+ there was.
+ (merge e228c17 js/lift-parent-count-limit later to maint).
+
+ * The basic test used to leave unnecessary trash directories in the
+ t/ directory.
+ (merge 738a8be jk/test-framework-updates later to maint).
+
+ * "git merge-base --octopus" used to leave cleaning up suboptimal
+ result to the caller, but now it does the clean-up itself.
+ (merge 8f29299 bm/merge-base-octopus-dedup later to maint).
+
+ * A "gc" process running as a different user should be able to stop a
+ new "gc" process from starting, but it didn't.
+ (merge ed7eda8 km/gc-eperm later to maint).
+
+ * An earlier "clean-up" introduced an unnecessary memory leak.
+ (merge e1c1a32 jk/credential-plug-leak later to maint).
+
+ * "git add -A" (no other arguments) in a totally empty working tree
+ used to emit an error.
+ (merge 64ed07c nd/add-empty-fix later to maint).
+
+ * "git log --decorate" did not handle a tag pointed by another tag
+ nicely.
+ (merge 5e1361c bc/log-decoration later to maint).
+
+ * When we figure out how many file descriptors to allocate for
+ keeping packfiles open, a system with non-working getrlimit() could
+ cause us to die(), but because we make this call only to get a
+ rough estimate of how many is available and we do not even attempt
+ to use up all file descriptors available ourselves, it is nicer to
+ fall back to a reasonable low value rather than dying.
+ (merge 491a8de jh/rlimit-nofile-fallback later to maint).
+
+ * read_sha1_file(), that is the workhorse to read the contents given
+ an object name, honoured object replacements, but there was no
+ corresponding mechanism to sha1_object_info() that was used to
+ obtain the metainfo (e.g. type & size) about the object. This led
+ callers to weird inconsistencies.
+ (merge 663a856 cc/replace-object-info later to maint).
+
+ * "git cat-file --batch=", an admittedly useless command, did not
+ behave very well.
+ (merge 6554dfa jk/cat-file-regression-fix later to maint).
+
+ * "git rev-parse <revs> -- <paths>" did not implement the usual
+ disambiguation rules the commands in the "git log" family used in
+ the same way.
+ (merge 62f162f jk/rev-parse-double-dashes later to maint).
+
+ * "git mv A B/", when B does not exist as a directory, should error
+ out, but it didn't.
+ (merge c57f628 mm/mv-file-to-no-such-dir-with-slash later to maint).
+
+ * A workaround to an old bug in glibc prior to glibc 2.17 has been
+ retired; this would remove a side effect of the workaround that
+ corrupts system error messages in non-C locales.
+
+ * SSL-related options were not passed correctly to underlying socket
+ layer in "git send-email".
+ (merge 5508f3e tr/send-email-ssl later to maint).
+
+ * "git commit -v" appends the patch to the log message before
+ editing, and then removes the patch when the editor returned
+ control. However, the patch was not stripped correctly when the
+ first modified path was a submodule.
+ (merge 1a72cfd jl/commit-v-strip-marker later to maint).
+
+ * "git fetch --depth=0" was a no-op, and was silently ignored.
+ Diagnose it as an error.
+ (merge 5594bca nd/transport-positive-depth-only later to maint).
+
+ * Remote repository URL expressed in scp-style host:path notation are
+ parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
+ to connect to user's home directory on host at address ::1.
+ (merge a2036d7 tb/clone-ssh-with-colon-for-port later to maint).
+
+ * "git diff -- ':(icase)makefile'" was unnecessarily rejected at the
+ command line parser.
+ (merge 887c6c1 nd/magic-pathspec later to maint).
+
+ * "git cat-file --batch-check=ok" did not check the existence of
+ the named object.
+ (merge 4ef8d1d sb/sha1-loose-object-info-check-existence later to maint).
+
+ * "git am --abort" sometimes complained about not being able to write
+ a tree with an 0{40} object in it.
+ (merge 77b43ca jk/two-way-merge-corner-case-fix later to maint).
+
+ * Two processes creating loose objects at the same time could have
+ failed unnecessarily when the name of their new objects started
+ with the same byte value, due to a race condition.
+ (merge b2476a6 jh/loose-object-dirs-creation-race later to maint).

-pointed by remote tags that it does not yet have, then fetch
-those missing tags. If the other end has tags that point at
-branches you are not interested in, you will not get them.
+By default, tags are auto-followed. This means that when fetching
+from a remote, any tags on the remote that point to objects that exist
+in the local repository are fetched. The effect is to fetch tags that
+point at branches that you are interested in. This default behavior
+can be changed by using the --tags or --no-tags options, by
+configuring remote.<name>.tagopt, or by using a refspec that fetches
+tags explicitly.
'git fetch' can fetch from either a single named repository,
or from several repositories at once if <group> is given and
there is a remotes.<group> entry in the configuration file.
(See linkgit:git-config[1]).
+When no remote is specified, by default the `origin` remote will be used,
+unless there's an upstream branch configured for the current branch.

+Notes
+-----
+
+git-filter-branch allows you to make complex shell-scripted rewrites
+of your Git history, but you probably don't need this flexibility if
+you're simply _removing unwanted data_ like large files or passwords.
+For those operations you may want to consider
+link:http://rtyley.github.io/bfg-repo-cleaner/[The BFG Repo-Cleaner],
+a JVM-based alternative to git-filter-branch, typically at least
+10-50x faster for those use-cases, and with quite different
+characteristics:
+
+* Any particular version of a file is cleaned exactly _once_. The BFG,
+ unlike git-filter-branch, does not give you the opportunity to
+ handle a file differently based on where or when it was committed
+ within your history. This constraint gives the core performance
+ benefit of The BFG, and is well-suited to the task of cleansing bad
+ data - you don't care _where_ the bad data is, you just want it
+ _gone_.
+
+* By default The BFG takes full advantage of multi-core machines,
+ cleansing commit file-trees in parallel. git-filter-branch cleans
+ commits sequentially (ie in a single-threaded manner), though it
+ _is_ possible to write filters that include their own parallellism,
+ in the scripts executed against each commit.
+
+* The link:http://rtyley.github.io/bfg-repo-cleaner/#examples[command options]

-
-Finds dangling commits and tags from the object database, and
-creates refs to them in the .git/lost-found/ directory. Commits and
-tags that dereference to commits are stored in .git/lost-found/commit,
-and other objects are stored in .git/lost-found/other.

-OUTPUT
-------
-Prints to standard output the object names and one-line descriptions
-of any commits or tags found.
-
-EXAMPLE
--------
-
-Suppose you run 'git tag -f' and mistype the tag to overwrite.
-The ref to your tag is overwritten, but until you run 'git
-prune', the tag itself is still there.

-SYNOPSIS
---------

-'git tar-tree' [--remote=<repo>] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-THIS COMMAND IS DEPRECATED. Use 'git archive' with `--format=tar`
-option instead (and move the <base> argument to `--prefix=base/`).
-
-Creates a tar archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated tar archive.
-
-'git tar-tree' behaves differently when given a tree ID versus when given
-a commit ID or tag ID. In the first case the current time is used as
-modification time of each file in the archive. In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored in a global extended pax header.
-It can be extracted using 'git get-tar-commit-id'.
-
-OPTIONS
--------
-
-<tree-ish>::
- The tree or commit to produce tar archive for. If it is
- the object name of a commit object.
-
-<base>::
- Leading path to the files in the resulting tar archive.
-
---remote=<repo>::
- Instead of making a tar archive from local repository,
- retrieve a tar archive from a remote repository.
-
-CONFIGURATION
--------------
-
-tar.umask::
- This variable can be used to restrict the permission bits of
- tar archive entries. The default is 0002, which turns off the
- world write bit. The special value "user" indicates that the
- archiving user's umask will be used instead. See umask(2) for
- details.
-
-EXAMPLES
---------
-`git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)`::
-
- Create a tar archive that contains the contents of the
- latest commit on the current branch, and extracts it in
- `/var/tmp/junk` directory.

+A thin pack is one with deltas which reference base objects not

+Receive-pack, on the other hand, is assumed by default to be able to
