 The dates in the following release notes denote when Chrome and the NaCl SDK
 reached canary status. The stable release is typically 6 weeks later.

 SDK
 ---
 
 * The SDK now contains experimental versions of ``i686-nacl-clang``,
   ``x86_64-nacl-clang``, and ``arm-nacl-clang`` as well as the ``clang++``
   equivalents. These toolchains are based on the same LLVM version as PNaCl, but
   can be used to generate NaCl ``.nexe`` files instead of translating a
   ``.pexe`` locally or using the GCC toolchain.
 
 NaCl
 ----
 
 * The x86 NaCl validators accept instructions from the FMA3 extensions, as well
-  as AVX2 instructions (except `VGATHER`).

 PNaCl
 -----
 
-* PNaCl supports C11/C++11 memory orders `acquire`, `release`, and `acq_rel`. It
-  used to upgrade all accesses to `seq_cst`. It still upgrades `consume` to
-  `acquire` (no compiler currently implements `consume`), and `relaxed` to
-  `seq_cst` (to conservatively avoid platform differences due to out-of-thin-air
-  problems). This is currently disabled by default in the SDK so that the
-  in-browser translator installed on users' machines has time to gain this
-  support. Developers can turn it on by passing the

 * PNaCl handles nested struct type expansion, which allows it to better support
   non-C languages such as Rust.
 * PNaCl breaks up many integer operations over 64-bits into individual 64-bit
   operations. This is often encountered when using large consecutive bitfields.

 * The ``CompletionCallbackFactory`` class template now takes a thread traits
   class as its second parameter. For details see the `CompletionCallbackFactory
