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 Version 0.4.1 (2019-02-05): * Better support for Skylake Core i5 (#76) * Misdiagnosis microarchitecture for i3-3220T (#81) * Ability to dump MSR values to a file (PR #82) * AMD Ryzen support (#86) * Support for Coffee and Kaby Lake (#104) * Support for Raven Ridge and Threadripper (#106) * Support for Pinnacle Ridge (#111) * Fix P-III Celeron misdetection * Support for Skylake-X (#116) * Support for Zen+ Threadripper Version 0.5.0 (2020-05-23): * A backwards-incompatible change, since the sizeof cpu_raw_data_t and cpu_id_t are now different. * Support for Hygon Dhyana (#123) * Support for Zen 2 (#125, #137) * Stubs for AArch64 (#127) * Support for Intel AVX512VNNI detection (#129) * Typo fixes (#130) * Support for get_total_cpus on Haiku (#131) * Fix build on PPC (#132) * Support for CMake build system (#138) and vcpkg packaging (#140) * Support for Cannon Lake * Support for Coffee Lake-U and Coffee Lake Refresh * Support for Comet Lake * Support for Ice Lake * Support for Renoir * Fix ThreadSanitizer report (#142) * Better support of L1 intruction cache (--l1i-assoc, --l1i-cacheline) * Support for Ivy Bridge-E (Xeon) * Support up to 4 subleaf entries for CPUID leaf 0x8000001D and fix detection of L3 cache on Zen 2 * Support for RDSEED/ADX/SHA_NI detection (AMD) * Support for ABM/AVX512VBMI/AVX512VBMI2 detection (Intel) Version 0.5.1 (2021-03-20): * Convert all python scripts to Python 3 * Support for Kaby Lake Refresh * Support for Kaby Lake-G * Support for Comet Lake-U * Support for Gemini Lake * Support for Vermeer * Support for Whiskey Lake-U * Support for Cezanne * Support for Milan * Support for Rocket Lake
