History

1.10

Fix bad include of sub-BSD os headers from main BSD header.
Fix use of deprecated TARGET_IPHONE_SIMULATOR instead of newer TARGET_OS_SIMULATOR.
Add BOOST_PLAT_ANDROID to resolve conflict between Linux and Android OS predefs. The BOOST_OS_ANDROID predef is now deprecated and will be removed in a future release.
Add support for consuming Predef as a CMake project.
Add support for consuming Predef as a standalone B2 project.

1.9

Fixes for BOOST_COMP_NVCC* predefs. (from Benjamin Worpitz)
Add specific version information for Cygwin OS predef. (from James E. King III)

1.8

Add support for __ARM_ARCH macro. (from Tim Blechmann)
Add detection for PTX architecture. (from Benjamin Worpitz)
Add nvcc compiler detection. (from Benjamin Worpitz)
Add support for detecting CUDA. (from Benjamin Worpitz)
Remove reference to obsolete BOOST_ARCH_AMD64. (from Peter Kolbus)

1.7

Fix BOOST_ARCH_PARISK/BOOST_ARCH_PARISC typo.
Improved Windows Universal Platform detection. (from James E. King, III)
Add detection for CloudABI with cloudlibc. (from James E. King, III)

1.6

Fix Intel C/C++ version 9999 detection to be 12.1.0.
Addition of BOOST_PREDEF_WORKAROUND and BOOST_PREDEF_TESTED_AT macros for defect workarounds and detection.
Add ARM64 MSVC SIMD detection. (from Minmin Gong)
Add detection of iOS simulator vs device as a platform choice. (from Ruslan Baratov)
Fix MinGW incorrect header guard. (from Ruslan Baratov)

1.5

Fix Intel C/C++ compiler version specification.
Add BOOST_VERSION_NUMBER_MAJOR, BOOST_VERSION_NUMBER_MINOR, BOOST_VERSION_NUMBER_PATCH macros to extract components from valid version numbers.
Change VS version numbering. Version after VS2015 will use the compiler version instead of the varied product versions.

1.4.1

Small fixes for some redefinition errors, and mispelled macros.
Slightly rearrangement of structure to comply with current library requirements.

1.4

Add detection of SIMD hardware. With the addition of the BOOST_HW_* category (from Charly Chevalier).
Add compile only version of check utilities to address cross-compile use cases. And changed the BBv2 check support to use compile only checks.
Fix test warnings.
Fix typos on AVAILABLE macros for Windows Platform. (from Vemund Handeland)

1.3

Fix many problems with predef_check functionality.
Update SunPro detection to accomodate latest version of compiler from Oracle.
Addition of Travis-CI and Appveyor testing.
Add and and or logical operators for predef_check expression on the Boost Build side.
Fix BOOST_ARCH_PARISC to correctly spelled name (from Graham Hanson).
Fix MAKE_YYYYM macros to correctly limit the month (from rick68).

1.2

Account for skip in Visual Studio product version vs. compiler version. This supports version of VS 2015 an onward.
Add detection of Haiku OS (from Jessica Hamilton).
Some fixes to endian detection for Android (from mstahl-at-redhat.com).
Add missing BOOST_PREDEF_MAKE_0X_VVRRPP macro (from Erik Lindahl).
Add predef_check program and BBv2 integration for build configuration checks.

1.1

Addition of BOOST_PLAT_* platform definitions for MinGW and Windows platform variants.
Detection of ARM architecture for Windows compilers to target mobile devices of Windows 8.
Improved ARM detection for 64 bit ARM.
Added detection of iOS an an operating system.
Improved detection of endianess on some platforms.
Addition of exclusive plus emulated definitions for platform and compiler detection.

	Warning
	The big change for this version is the restructuring of the definitions to avoid duplicate definitions in one category. That is, only one `BOOST_OS_`, `BOOST_COMP_`, and `BOOST_PLAT_*` variant will be detected (except for sub-categories).
