+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.
+
+Also contains various documentation updates and code clean-ups.
