 Fixes since v1.8.3.2
 --------------------
 
+ * "git apply" parsed patches that add new files, generated by programs
+   other than Git, incorrectly.  This is an old breakage in v1.7.11.
+
+ * 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.
+
+ * "git pull" into nothing trashed "local changes" that were in the
+   index.
+
+ * Many "git submodule" operations did not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in its error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
  * "gitweb" forgot to clear a global variable $search_regexp upon each
    request, mistakenly carrying over the previous search to a new one
    when used as a persistent CGI.

+   This function helps systems whose filesystem does not support symbolic

+   important that the file system entry is a symbolic link, i.e., instead
+   of the sequence
+
+	ln -s foo bar &&
+	git add bar
+
+   Sometimes it is possible to split a test in a part that does not need
+   the symbolic link in the file system and a part that does; then only
+   the latter part need be protected by a SYMLINKS prerequisite (see below).
