+Git v1.8.3.2 Release Notes
+==========================
+
+Fixes since v1.8.3.1
+--------------------
+
+ * Cloning with "git clone --depth N" while fetch.fsckobjects (or
+ transfer.fsckobjects) is set to true did not tell the cut-off
+ points of the shallow history to the process that validates the
+ objects and the history received, causing the validation to fail.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+ "git checkout -t -b foo remotes/origin/foo". This codepath has been
+ updated to correctly take existing remote definitions into account.
+
+ * "git fetch" into a shallow repository from a repository that does
+ not know about the shallow boundary commits (e.g. a different fork
+ from the repository the current shallow repository was cloned from)
+ did not work correctly.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+ checks to lose data at the remote side.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+ not pay attention to the fact that the merge base between A and B
+ was the bottom of the range being specified.
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+ another hunk immediately begins where the earlier one ends.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+ incorrectly when your previous branch was "frotz" (it should be
+ rewritten to "git merge frotz~22" instead).
+
+ * "git commit --allow-empty-message -m ''" should not start an
+ editor.
+
+ * "git push --[no-]verify" was not documented.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+ can take in the HTML documentation was made into a clickable link
+ by mistake.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+ work due to slight differences in array variable notation between
+ these two shells.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+ being rebased when "rebase -i/-m/-p" modes are in use, but not the
+ plain vanilla "rebase".
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+ it was easy to flip it around while push is still going on and push
+ out a branch that the user did not originally intended when the
+ command was started.
+
+ * "difftool --dir-diff" did not copy back changes made by the
+ end-user in the diff tool backend to the working tree in some
+ cases.

+Git v1.8.3.3 Release Notes
+==========================
+
+Fixes since v1.8.3.2
+--------------------
+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+ bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+ their CommonCrypto, not with OpenSSL.
UI, Workflows & Features
+ * Various subcommands of "git submodule" refused to run from anywhere
+ other than the top of the working tree of the superproject, but
+ they have been taught to let you run from a subdirectory.
+
+ * "git diff" learned a mode that ignores hunks whose change consists
+ only of additions and removals of blank lines, which is the same as
+ "diff -B" (ignore blank lines) of GNU diff.
+
* "git rm" gives a single message followed by list of paths to report
multiple paths that cannot be removed.
Performance, Internal Implementation, etc.
+ * "git pack-refs" that races with new ref creation or deletion have
+ been susceptible to lossage of refs under right conditions, which
+ has been tightened up.
+
+ * We read loose and packed rerferences in two steps, but after
+ deciding to read a loose ref but before actually opening it to read
+ it, another process racing with us can unlink it, which would cause
+ us to barf. The codepath has been updated to retry when such a
+ race is detected, instead of outright failing.
+
* Uses of the platform fnmatch(3) function (many places in the code,
matching pathspec, .gitignore and .gitattributes to name a few)
have been replaced with wildmatch, allowing "foo/**/bar" that would
track are contained in this release (see release notes to them for
details).
+ * "git name-rev --refs=tags/v*" were forbidden, which was a bit
+ inconvenient (you had to give a pattern to match refs fully, like
+ --refs=refs/tags/v*).
+ (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint).
+
* "git apply" parsed patches that add new files, generated by
programs other than Git, incorrectly. This is an old breakage in
v1.7.11 and will need to be merged down to the maintanance tracks.
(merge 212eb96 tr/maint-apply-non-git-patch-parsefix later to maint).
+ * Older cURL wanted piece of memory we call it with to be stable, but
+ we updated the auth material after handing it to a call.
+ (merge a94cf2c bc/http-keep-memory-given-to-curl later to maint).
+
+ * "git pull" into nothing trashed "local changes" that were in the
+ index, and this avoids it.
+ (merge b4dc085 jk/pull-into-dirty-unborn later to maint).
+
* Many "git submodule" operations do not work on a submodule at a
path whose name is not in ASCII.

-----------
Create a stash (which is a regular commit object) and return its
object name, without storing it anywhere in the ref namespace.
+ This is intended to be useful for scripts. It is probably not
+ the command you want to use; see "save" above.
+store::
+
+ Store a given stash created via 'git stash create' (which is a
+ dangling merge commit) in the stash ref, updating the stash
