+* The ``.inst`` assembler directive is now usable on both COFF and Mach-O

+Changes to the ARM Target
+-------------------------
+
+* The ``.inst`` assembler directive is now usable on both COFF and Mach-O
+  targets, in addition to ELF. For Thumb, it can now also automatically
+  deduce the instruction size, without having to specify it with
+  e.g. ``.inst.w`` as before.
+
+Changes to the Hexagon Target
+-----------------------------
+
+* Hexagon now supports auto-vectorization for HVX. It is disabled by default
+  and can be turned on with ``-fvectorize``. For auto-vectorization to take
+  effect, code generation for HVX needs to be enabled with ``-mhvx``.
+  The complete set of options should include ``-fvectorize``, ``-mhvx``,
+  and ``-mhvx-length={64b|128b}``.
+
+* The support for Hexagon ISA V4 is deprecated and will be removed in the
+  next release.

 Changes to the X86 Target

- During this release ...
+* The calling convention for the ``f80`` data type on MinGW targets has been
+  fixed. Normally, the calling convention for this type is handled within clang,
+  but if an intrinsic is used, which LLVM expands into a libcall, the
+  proper calling convention needs to be supported in LLVM as well. (Note,
+  on Windows, this data type is only used for long doubles in MinGW
+  environments - in MSVC environments, long doubles are the same size as
+  normal doubles.)
