+* The optimization to move the prologue and epilogue of functions in colder
+  code path (shrink-wrapping) is now enabled by default.
+
+* A new target-independent gcc-compatible emulated Thread Local Storage mode
+  is added.  When ``-femultated-tls`` flag is used, all accesses to TLS
+  variables are converted to calls to ``__emutls_get_address`` in the runtime
+  library.
+
+* MSVC compatible exception handling has been completely overhauled. New
+  instructions have been introduced to facilitate this:
+  `New exception handling instructions <ExceptionHandling.html#new-exception-handling-instructions>`_. 
+  While we have done our best to test this feature thoroughly, it would
+  not be completely surprising if there were a few lingering issues that

+Changes to the ARM Backends
+---------------------------
+
+During this release the AArch64 target has:
+
+* Added support for more sanitizers (MSAN, TSAN) and made them compatible with
+  all VMA kernel configurations (currently tested on 39 and 42 bits).
+* Gained initial LLD support in the new ELF back-end
+* Extended the Load/Store optimiser and cleaned up some of the bad decisions
+  made earlier.
+* Expanded LLDB support, including watchpoints, native building, Renderscript,
+  LLDB-server, debugging 32-bit applications.
+* Added support for the ``Exynos M1`` chip.
+
+During this release the ARM target has:
+
+* Gained massive performance improvements on embedded benchmarks due to finally
+  running the stride vectorizer in full form, incrementing the performance gains
+  that we already had in the previous releases with limited stride vectorization.
+* Expanded LLDB support, including watchpoints, unwind tables
+* Extended the Load/Store optimiser and cleaned up some of the bad decisions
+  made earlier.
+* Simplified code generation for global variable addresses in ELF, resulting in
+  a significant (4% in Chromium) reduction in code size.
+* Gained some additional code size improvements, though there's still a long road
+  ahead, especially for older cores.
+* Added some EABI floating point comparison functions to Compiler-RT
+* Added support for Windows+GNU triple, +features in -mcpu/-march options.
 
 
 Changes to the MIPS Target

 * TLS is enabled for Cygwin as emutls.
 
+* Smaller code for materializing 32-bit 1 and -1 constants at ``-Os``.
+
+* More efficient code for wide integer compares. (E.g. 64-bit compares
+  on 32-bit targets.)
+
+* Tail call support for ``thiscall``, ``stdcall``, ``vectorcall``, and
+  ``fastcall`` functions.
+
+Changes to the Hexagon Target
+-----------------------------
+
+In addition to general code size and performance improvements, Hexagon target
+now has basic support for Hexagon V60 architecture and Hexagon Vector
+Extensions (HVX).
+
+Changes to the AVR Target
+-------------------------
+
+Slightly less than half of the AVR backend has been merged in at this point. It is still
+missing a number large parts which cause it to be unusable, but is well on the
+road to being completely merged and workable.
