+* Lots of improvements to generation of Windows unwind data; the unwind
+  data is optimized and written in packed form where possible, reducing
+  the size of unwind data (pdata and xdata sections) by around 60%

+* Support for creating Windows unwind data using ``.seh_*`` assembler

+
+* Produce proper assembly output for the Windows target, including
+  ``:lo12:`` relocation specifiers, to allow the assembly output
+  to actually be assembled.
