+it 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 is encouraged to use "git add --ignore-removal <path>" and
+get used to it.
Updates since v1.8.2
--------------------
+Foreign interface
+
+ * remote-hg and remote-bzr helpers (in contrib/) have been updated.
+
+
UI, Workflows & Features
+ * "git branch --vv" learned to paint the name of the branch it
+ integrates with in a different color (color.branch.upstream,
+ which defaults to blue).
+
+ * In a sparsely populated working tree, "git checkout <pathspec>" no
+ longer unmarks paths that match the given pathspec that were
+ originally ignored with "--sparse" (use --ignore-skip-worktree-bits
+ option to resurrect these paths out of the index if you really want
+ to).
+
+ * "git log --format" specifier learned %C(auto) token that tells Git
+ to use color when interpolating %d (decoration), %h (short commit
+ object name), etc. for terminal output.
+
+ * "git bisect" leaves the final outcome as a comment in its bisect
+ log file.
+
+ * "git clone --reference" can now refer to a gitfile "textual symlink"
+ that points at the real location of the repository.
+
+ * "git count-objects" learned "--human-readable" aka "-H" option to
+ show various large numbers in Ki/Mi/GiB scaled as necessary.
+
+ * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense,
+ and a more readable error message e.g. "can't cherry-pick a tree"
+ is given (we used to say "expected exactly one commit").
+
+ * The "--annotate" option to "git send-email" can be turned on (or
+ off) by default with sendemail.annotate configuration variable (you
+ can use --no-annotate from the command line to override it).
+
+ * The "--cover-letter" option to "git format-patch" can be turned on
+ (or off) by default with format.coverLetter configuration
+ variable. By setting it to 'auto', you can turn it on only for a
+ series with two or more patches.
+
+ * The bash completion support (in contrib/) learned that cherry-pick
+ takes a few more options than it already knew about.
+
+ * "git help" learned "-g" option to show the list of guides just like
+ list of commands are given with "-a".
+
+ * A triangular "pull from one place, push to another place" workflow
+ is supported better by new remote.pushdefault (overrides the
+ "origin" thing) and branch.*.pushremote (overrides the
+ branch.*.remote) configuration variables.
+
+ * "git status" learned to report that you are in the middle of a
+ revert session, just like it does for a cherry-pick and a bisect
+ session.
+
+ * The handling by "git branch --set-upstream-to" against various forms
+ of erroneous inputs was suboptimal and has been improved.
+
* When the interactive access to git-shell is not enabled, it issues
- a message meant to help the system admininstrator to enable it.

An explicit way to help the end users who connect to the service by
issuing custom messages to refuse such an access has been added.
ref by specifying a raw object name from the command line when the
server side supports this feature.
+ * Output from "git log --graph" works better with submodule log
+ output now.
+
* "git count-objects -v" learned to report leftover temporary
packfiles and other garbage in the object store.
* Updates for building under msvc.
+ * A handful of issues in the code to traverse working tree to find
+ untracked and/or ignored files have been fixed, and the general
+ codepath involved in "status -u" and "clean" have been cleaned up
+ and optimized.
+
+ * The stack footprint of some codepaths that access an object from a
+ pack has been shrunk.
+
+ * The logic to coalesce the same lines removed from the parents in
+ the output from "diff -c/--cc" has been updated, but with an O(n^2)
+ complexity, so this might turn out to be undesirable.
+
+ * The code to enforce permission bits on files in $GIT_DIR/ for
+ shared repositories have been simplified.
+
* A few codepaths knew how much data they need to put in the
hashtables they use upfront, but still started from a small table
repeatedly growing and rehashing.
which have been consolidated. Also a bug in "git checkout dir/"
that is started from an unmerged index has been fixed.
+ * A few bugfixes to "git rerere" working on corner case merge
+ conflicts have been applied.

Fixes since v1.8.2
track are contained in this release (see release notes to them for
details).
+ * When receive-pack detects error in the pack header it received in
+ order to decide which of unpack-objects or index-pack to run, it
+ returned without closing the error stream, which led to a hang
+ sideband thread.
+
+ * Zsh completion forgot that '%' character used to signal untracked
+ files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+ crashed some code that trusted that a name, an email and an
+ timestamp can always be found in it.
+
+ * When "upload-pack" fails while generating a pack in response to
+ "git fetch" (or "git clone"), the receiving side mistakenly said
+ there was a programming error to trigger the die handler
+ recursively.
+
+ * "rev-list --stdin" and friends kept bogus pointers into input
+ buffer around as human readble object names. This was not a huge
+ problem but was exposed by a new change that uses these names in
+ error output.
+ (merge 70d26c6 tr/copy-revisions-from-stdin later to maint).
+
+ * Smart-capable HTTP servers were not restricted via the
+ GIT_NAMESPACE mechanism when talking with commit-walker clients,
+ like they do when talking with smart HTTP clients.
+ (merge 6130f86 jk/http-dumb-namespaces later to maint).
+
+ * "git merge-tree" did not omit a merge result that is identical to
+ "our" side in certain cases.
+ (merge aacecc3 jk/merge-tree-added-identically later to maint).
+
+ * Perl scripts like "git-svn" closed (not redirecting to /dev/null)
+ the standard error stream, which is not a very smart thing to do.
+ Later open may return file descriptor #2 for unrelated purpose, and
+ error reporting code may write into them.
+
+ * "git show-branch" was not prepared to show a very long run of
+ ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.
+
+ * "git diff --diff-algorithm algo" is also understood as "git diff
+ --diff-algorithm=algo".
+
+ * The new core.commentchar configuration was not applied to a few
+ places.
+
+ * "git bundle" did not like a bundle created using a commit without
+ any message as its one of the prerequistes.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+ there was no way to disable this. Make it honor --no-textconv
+ option.
+
+ * When used with "-d temporary-directory" option, "git filter-branch"
+ failed to come back to the original working tree to perform the
+ final clean-up procedure.
+
* "git merge $(git rev-parse v1.8.2)" behaved quite differently from
"git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
not pay much attention to the annotated tag payload. Make the code
notice the type of the tag object, in addition to the dwim_ref()
based classification the current code uses (i.e. the name appears
in refs/tags/) to decide when to special case merging of tags.
- (merge a38d3d7 jc/merge-tag-object later to maint).
* Fix 1.8.1.x regression that stopped matching "dir" (without
trailing slash) to a directory "dir".
* The prompt string generator (in contrib/completion/) did not notice
when we are in a middle of a "git revert" session.
- (merge 3ee4452 rr/prompt-revert-head later to maint).
* "submodule summary --summary-limit" option did not support
"--option=value" form.
- (merge 862ae6c rs/submodule-summary-limit later to maint).
- * "index-pack --fix-thin" used uninitialize value to compute delta
- depths of objects it appends to the resulting pack.
- (merge 57165db jk/index-pack-correct-depth-fix later to maint).
+ * "index-pack --fix-thin" used an uninitialized value to compute
+ delta depths of objects it appends to the resulting pack.
* "index-pack --verify-stat" used a few counters outside protection
of mutex, possibly showing incorrect numbers.
- (merge 8f82aad nd/index-pack-threaded-fixes later to maint).
* The code to keep track of what directory names are known to Git on
platforms with case insensitive filesystems can get confused upon a
correctly to the ls-remote and fetch with recent version of Git.
* Recent optimization broke shallow clones.
- (merge f59de5d jk/peel-ref later to maint).

instead the parser kept reading beyond the end of the string.
