- Loop Vectorizer
- ---------------
- We've continued the work on the loop vectorizer. The loop vectorizer now has the following features:
-  # Loops with unknown trip count.
-  # Runtime checks of pointers
-  # Reductions, Inductions
-  # If Conversion
-  # Pointer induction variables
-  # Reverse iterators
-  # Vectorization of mixed types
-  # Vectorization of function calls
-  # Partial unrolling during vectorization
-
-  We've also improved the X86 and ARM cost model.
-
-  TargetTransformInfo
-  -------------------
-  TargetTransformInto (TTI) is a new interface that can be used by IR-level passes
-  to obtain target-specific information, such as the costs of instructions. Only "Lowering"
-  passes such as LSR and the vectorizer are allowed to use the TTI infrastructure.

+AArch64 target
+--------------
+
+We've added support for AArch64, ARM's 64-bit architecture. Development is still
+in fairly early stages, but we expect successful compilation when:
+
+- compiling standard compliant C99 and C++03 with Clang;
+- using Linux as a target platform;
+- where code + static data doesn't exceed 4GB in size (heap allocated data has
+  no limitation).
+
+Some additional functionality is also implemented, notably DWARF debugging,
+GNU-style thread local storage and inline assembly.

+R600 Backend
+------------
+
+The R600 backend was added in this release, it supports AMD GPUs
+(HD2XXX - HD7XXX).  This backend is used in AMD's Open Source
+graphics / compute drivers which are developed as part of the `Mesa3D
+<http://www.mesa3d.org>`_ project.
