 * 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
+  early adopters might bump into.
