   for more details.
 
+* ``ValueTypes.td`` is made richer to represent attributes for
+  ``MVT``.
+
+* ``Intrinsics.td`` is able to emit definitions of
+  ``TypeSig``. ``IntrinsicEmitter`` doesn't depend on
+  ``MachineValueTypes.h`` anymore.
+
+* ``llvm/CodeGen/MachineValueType.h`` is moved from ``llvm/Support``.
+  It uses values defined in ``ValueTypes.td``.
+
 Changes to building LLVM
 ------------------------
 
+* ``llvm-min-tblgen`` is internally introduced to build LLVM public
+  headers. Note that ``llvm-tblgen`` depends on `GenVT.inc` that is
+  generated by ``llvm-min-tblgen``. Specify the external
+  ``llvm-tblgen`` for ``LLVM_TABLEGEN`` when you use prebuilt tablegen
+  tools, since ``llvm-tblgen`` is built as the superset of
+  ``llvm-min-tblgen``.
+
 Changes to TableGen
 -------------------
 
 * Named arguments are supported. Arguments can be specified in the form of
   ``name=value``.
 
+* Each tablegen backend can declare itself as self-contained with
+  ``llvm::TableGen::Emitter`` as the registry. You don't need to
+  append entries and options to ``TableGen.cpp``. For now, It is
+  applied only to ``llvm-tblgen``.
+
+* The new bang operator ``!range(m, n)`` is introduced.
+
+* A list subscript ``list_var[i]`` accepts not only immutable values
+  but also expressions.
+
+* A list slice ``list_foo[list_bar]`` accepts ``list<int>``
+  expressions.

 Changes to Optimizations
