RELEASE HISTORY
---------------

January 2017 (3.10)
    Added XMVectorSum for horizontal adds
    ARMv8 intrinsics use for ARM64 platform (division, rounding, half-precision conversion)
    Added SSE3 codepaths using opt-in _XM_SSE3_INTRINSICS_
    XMVectorRound fix for no-intrinsics to match round to nearest (even)
    XMStoreFloat3SE fix when max channel isn't a perfect power of 2
    constexpr conformance fix and workaround for compiler bug in VS 2015 RTM
    Remove support for VS 2012 compilers
    Remove __vector4i deprecated type

June 2016 (3.09)
    Includes support for additional optimizations when built with /arch:AVX or /arch:AVX2
    Added use of constexpr for type constructors, XMConvertToRadians, and XMConvertToDegrees
    Marked __vector4i, XMXDEC4, XMDECN4, XMDEC4, and associated Load & Store functions as deprecated.
        These are vestiges of Xbox 360 support and will be removed in a future release
    Renamed parameter in XMMatrixPerspectiveFov* to reduce user confusion when relying on IntelliSense
    XMU565, XMUNIBBLE4 constructors take uint8_t instead of int8_t

May 2016
    DirectXMath 3.08 released under the MIT license

November 2015 (3.08)
    Added use of _mm_sfence for Stream methods
    Fixed bug with non-uniform scaling transforms for BoundingOrientedBox
    Added asserts for Near/FarZ in XMMatrix* methods
    Added use of =default for PODs with VS 2013/2015
    Additional SSE and ARM-NEON optimizations for PackedVector functions

April 2015 (3.07)
    Fix customer reported bugs in BoundingBox methods
    Fix customer reported bug in XMStoreFloat3SE  
    Fix customer reported bug in XMVectorATan2, XMVectorATan2Est  
    Fix customer reported bug in XMVectorRound 

October 2013 (3.06)
    Fixed load/store of XMFLOAT3SE to properly match the DXGI_FORMAT_R9G9B9E5_SHAREDEXP
    Added XMLoadUDecN4_XR and XMStoreUDecN4_XR to match DXGI_FORMAT_R10G10B10_XR_BIAS_A2_UNORM
    Added XMColorRGBToSRGB and XMColorSRGBToRGB to convert linear RGB <-> sRGB

July 2013 (3.05)
    Use x86/x64 __vectorcall calling-convention when available (XM_CALLCONV, HXMVECTOR, FXMMATRIX introduced)
    Fixed bug with XMVectorFloor and XMVectorCeiling when given whole odd numbers (i.e. 105.0)
    Improved XMVectorRound algorithm
    ARM-NEON optimizations for XMVectorExp2, XMVectorLog2, XMVectorExpE, and XMVectorLogE  
    ARM-NEON code paths use multiply-by-scalar intrinsics when supported

    Fixed potential warning C4723 using operator/ or operator/=

March 2013 (3.04)
    XMVectorExp2, XMVectorLog2, XMVectorExpE, and XMVectorLogE functions added to provide base-e support in addition to the existing base-2 support
