Version 0.1.0 (2008-10-15):
* Initial public release
Version 0.1.1 (2009-07-06):
* Added intel_fn11 fields to cpu_raw_data_t to handle
new processor topology enumeration required on Core i7
* Support for Intel Nehalem architecture CPUs (Core i7, Xeon i7)
Version 0.1.2 (2009-09-26):
* Added support for MSR reading through self-extracting kernel driver
on Win32.
Version 0.1.3 (2010-04-20):
* Added support for greater more accurate CPU clock measurements with
cpu_clock_by_ic()
Version 0.2.0 (2011-10-11):
* Support for AMD Bulldozer CPUs, 128-bit SSE unit size checking.
A backwards-incompatible change, since the sizeof cpu_id_t is now
different.
Version 0.2.1 (2012-05-26):
* Support for Ivy Bridge, and detecting the presence of the RdRand
instruction.
Version 0.2.2 (2015-11-04):
* Support for newer processors up to Haswell and Vishera
* Fix clock detection in cpu_clock_by_ic() for Bulldozer
* Support for detection of AVX/AVX2/BMI1/BMI2
* More entries supported in cpu_msrinfo()
* Rename of some CPU codenames, made more consistent
* *BSD and Solaris support (unofficial)
Version 0.3.0 (2016-07-09):
* A backwards-incompatible change, since the sizeof cpu_raw_data_t and
cpu_id_t are now different.
* Support for processors up to Skylake.
* Fix clock detection in cpu_clock_by_ic() for Skylake.
* Support up to 8 subleaf entries for CPUID leaf 04 and detection
of L4 cache.
* MSR functions supported on FreeBSD.
* INFO_VOLTAGE request supported by cpu_msrinfo().
Version 0.4.0 (2016-09-30):
* A backwards-incompatible change, since the sizeof cpu_raw_data_t and
cpu_id_t are now different.
* Better detection of AMD clock multiplier with msrinfo.
* Support for Intel SGX detection
