  * The internal implementation of "git rebase -i" has been updated to
    avoid forking a separate "rebase--interactive" process.
+ * Allow DEP and ASLR for Windows build to for security hardening.
+ * Performance test framework has been broken and measured the version
+   of Git that happens to be on $PATH, not the specified one to
+   measure, for a while, which has been corrected.
+ * Optionally "make coccicheck" can feed multiple source files to
+   spatch, gaining performance while spending more memory.
+ * Attempt to use an abbreviated option in "git clone --recurs" is
+   responded by a request to disambiguate between --recursive and
+   --recurse-submodules, which is bad because these two are synonyms.
+   The parse-options API has been extended to define such synonyms
+   more easily and not produce an unnecessary failure.
+ * A pair of private functions in http.c that had names similar to
+   fread/fwrite did not return the number of elements, which was found
+   to be confusing.
+ * Update collision-detecting SHA-1 code to build properly on HP-UX.
