Updated matrix version Transform for BoundingOrientedBox and BoundingFrustum to handle scaling
March 2012 (3.03)
Breaking change: Removed union members from XMMATRIX type to make it a fully 'opaque' type
Marked single-parameter C++ constructors for XMFLOAT2, XMFLOAT2A, XMFLOAT3, XMFLOAT3A, XMFLOAT4, and XMFLOAT4A explicit
February 2012 (3.02)
ARM-NEON intrinsics (selected by default for the ARM platform)
reworked XMVectorPermute, change of XM_PERMUTE_ defines, removal of XMVectorPermuteControl
Addition of XM_SWIZZLE_ defines
Optimizations for transcendental functions
Template forms for permute, swizzle, shift-left, rotate-left, rotation-right, and insert
Removal of deprecated types and functions
(XM_CACHE_LINE_SIZE define, XMVectorExpEst, XMVectorLogEst, XMVectorPowEst, XMVectorSinHEs, XMVectorCosHEst, XMVectorTanHEst,
XMVector2InBoundsR, XMVector3InBoundsR, XMVector4InBoundsR)
Removed XM_STRICT_VECTOR4; XMVECTOR in NO-INTRINSICS always defined without .x, .y, .z, .w, .v, or .u
Additional bounding types
SAL fixes and improvements
September 2011 (3.00)
Renamed and reorganized the headers
Introduced C++ namespaces
Removed the Xbox 360-specific GPU types
(HENDN3, XMHEND3, XMUHENDN3, XMUHEND3, XMDHENN3, XMDHEN3,
XMUDHENN3, XMUDHEN3, XMXICON4, XMXICO4, XMICON4, XMICO4, XMUICON4, XMUICO4 )
