+Git v2.12.2 Release Notes
+=========================
+
+Fixes since v2.12.1
+-------------------
+
+ * "git status --porcelain" is supposed to give a stable output, but a
+   few strings were left as translatable by mistake.
+
+ * "Dumb http" transport used to misparse a nonsense http-alternates
+   response, which has been fixed.
+
+ * "git diff --quiet" relies on the size field in diff_filespec to be
+   correctly populated, but diff_populate_filespec() helper function
+   made an incorrect short-cut when asked only to populate the size
+   field for paths that need to go through convert_to_git() (e.g. CRLF
+   conversion).
+
+ * There is no need for Python only to give a few messages to the
+   standard error stream, but we somehow did.
+
+ * A leak in a codepath to read from a packed object in (rare) cases
+   has been plugged.
+
+ * "git upload-pack", which is a counter-part of "git fetch", did not
+   report a request for a ref that was not advertised as invalid.
+   This is generally not a problem (because "git fetch" will stop
+   before making such a request), but is the right thing to do.
+
+ * A "gc.log" file left by a backgrounded "gc --auto" disables further
+   automatic gc; it has been taught to run at least once a day (by
+   default) by ignoring a stale "gc.log" file that is too old.
+
+ * "git remote rm X", when a branch has remote X configured as the
+   value of its branch.*.remote, tried to remove branch.*.remote and
+   branch.*.merge and failed if either is unset.
+
+ * A caller of tempfile API that uses stdio interface to write to
+   files may ignore errors while writing, which is detected when
+   tempfile is closed (with a call to ferror()).  By that time, the
+   original errno that may have told us what went wrong is likely to
+   be long gone and was overwritten by an irrelevant value.
+   close_tempfile() now resets errno to EIO to make errno at least
+   predictable.
+
+ * "git show-branch" expected there were only very short branch names
+   in the repository and used a fixed-length buffer to hold them
+   without checking for overflow.
+
+ * The code that parses header fields in the commit object has been
+   updated for (micro)performance and code hygiene.
+
+ * A test that creates a confusing branch whose name is HEAD has been
+   corrected not to do so.
+
+ * "Cc:" on the trailer part does not have to conform to RFC strictly,
+   unlike in the e-mail header.  "git send-email" has been updated to
+   ignore anything after '>' when picking addresses, to allow non-address
+   cruft like " # stable 4.4" after the address.
+
+ * "git push" had a handful of codepaths that could lead to a deadlock
+   when unexpected error happened, which has been fixed.
+
+ * Code to read submodule.<name>.ignore config did not state the
+   variable name correctly when giving an error message diagnosing
+   misconfiguration.
+
+ * "git ls-remote" and "git archive --remote" are designed to work
+   without being in a directory under Git's control.  However, recent
+   updates revealed that we randomly look into a directory called
+   .git/ without actually doing necessary set-up when working in a
+   repository.  Stop doing so.
+
+ * The code to parse the command line "git grep <patterns>... <rev>
+   [[--] <pathspec>...]" has been cleaned up, and a handful of bugs
+   have been fixed (e.g. we used to check "--" if it is a rev).
+
+ * The code to parse "git -c VAR=VAL cmd" and set configuration
+   variable for the duration of cmd had two small bugs, which have
+   been fixed.
+   This supersedes jc/config-case-cmdline topic that has been discarded.
+
+Also contains various documentation updates and code clean-ups.

+Git version interoperability tests
+==================================
+
+This directory has interoperability tests for git. Each script is
+similar to the normal test scripts found in t/, but with the added twist
+that two special versions of git, "git.a" and "git.b", are available in
+the PATH. Individual tests can then check the interaction between the
+two versions.
+
+When you add a feature that handles backwards compatibility between git
+versions, it's encouraged to add a test here to make sure it behaves as
+you expect.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make".  This runs all
+the tests against their default versions.
+
+You can run a single test like:
+
+    $ ./i0000-basic.sh
+    ok 1 - bare git is forbidden
+    ok 2 - git.a version (v1.6.6.3)
+    ok 3 - git.b version (v2.11.1)
+    # passed all 3 test(s)
+    1..3
+
+Each test contains default versions to run against. You may override
+these by setting `GIT_TEST_VERSION_A` and `GIT_TEST_VERSION_B` in the
+environment. Note that not all combinations will give sensible outcomes
+for all tests (e.g., a test checking for a specific old/new interaction
+may want something "old" enough" and something "new" enough; see
+individual tests for details).
+
+Version names should be resolvable as revisions in the current
+repository. They will be exported and built as needed using the
+config.mak files found at the root of your working tree.
+
+The exception is the special version "." which uses the currently-built
+contents of your working tree.
+
+You can set the following variables (in the environment or in your config.mak):
+
+    GIT_INTEROP_MAKE_OPTS
+       Options to pass to `make` when building a git version (e.g.,
+       `-j8`).
+
+You can also pass any command-line options taken by ordinary git tests (e.g.,
+"-v").
+
+
+Naming Tests
+------------
+
+The interop test files are named like:
+
+       iNNNN-short-description.sh
+
+where N is a decimal digit.  The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+An interop test script starts like a normal script, declaring a few
+variables and then including interop-lib.sh (which includes test-lib.sh).
+Besides test_description, you should also set the $VERSION_A and $VERSION_B
+variables to give the default versions to test against. See t0000-basic.sh for
+an example.
+
+You can then use test_expect_success as usual, with a few differences:
+
+  1. The special commands "git.a" and "git.b" correspond to the
+     two versions.
+
+  2. You cannot call a bare "git". This is to prevent accidents where
+     you meant "git.a" or "git.b".
+
+  3. The trash directory is _not_ a git repository by default. You
+     should create one with the appropriate version of git.
+
+At the end of the script, call test_done as usual.

+# This mirrors a repeated push setup:
+#
+# 1. A client repeatedly modifies some files, makes a
+#      commit, and pushes the result. It does this N times
+#      before we get around to repacking.
+#
+# 2. Each push generates a thin pack with the new version of
+#    various objects. Let's consider some file in the root tree
+#    which is updated in each commit.
+#
+#    When generating push number X, we feed commit X-1 (and
+#    thus blob X-1) as a preferred base. The resulting pack has
+#    blob X as a thin delta against blob X-1.
+#
+#    On the receiving end, "index-pack --fix-thin" will
+#    complete the pack with a base copy of blob X-1.
+#
+# 3. In older versions of git, if we used the delta from
+#    pack X, then we'd always find blob X-1 as a base in the
+#    same pack (and generate a fresh delta).
+#
+#    But with the pack mru, we jump from delta to delta
+#    following the traversal order:
+#
+#      a. We grab blob X from pack X as a delta, putting it at
+#         the tip of our mru list.
+#
+#      b. Eventually we move onto commit X-1. We need other
+#         objects which are only in pack X-1 (in the test code
+#         below, it's the containing tree). That puts pack X-1
+#         at the tip of our mru list.
+#
+#      c. Eventually we look for blob X-1, and we find the
+#         version in pack X-1 (because it's the mru tip).
+#
+# Now we have blob X as a delta against X-1, which is a delta
+# against X-2, and so forth.
+#
+# In the real world, these small pushes would get exploded by
+# unpack-objects rather than "index-pack --fix-thin", but the
