v2.2.3

• Attempt to fix the memory leak in readFileAsBytes()

v2.2.2

• Renamed CPUTune.kext to CPUTuneCore.kext

v2.2.1

• Fixed a kernel panic when resart the timer in readConfigAtRuntime()

v2.2.0

• Fixed return status in start()
• Reverted to less aggressive MSR writters with null pointer protection
• Removed redudant log in setIfNotEqual

v2.1.9

• Fixed some nits

v2.1.8

• Protected against null pointer
• Fixed the readConfigAtRuntime read and set logic (use setIfNotEqual)
• Added Base to know region as new Xcode

v 2.1.7

• Fixed the kernel panic at boostrap due to write log to filesystem

v 2.1.6

• Fixed a kernel panic that reads MSR_IA32_HWP_REQUEST on CPUs unsupport HWP

v2.1.5

• Fixed the NVRAM log string buffer

v2.1.4

• Add version info for CPUTune; rename readFileNBytes to readFileAsBytes

v2.1.3

• Add line number, better code style for LOG and DBGLOG

v2.1.2

• Better logging with function name, more readable

v2.1.1

• Fixed timer sounce timeout in CPUTune::start

v2.1.0

• Introduce DBGLOG() macro to reduce the log noise
• Rename myLOG() to LOG()

v2.0.9

• Remove unused header in CPUInfo's header; bump to the right version

v2.0.8

• Check turbo rate limit RW/RO before writting to MSR

v2.0.7

v2.0.6

• Tune turbo ratio limit at runtime when turbo is enabled

v2.0.5

• Make code cleaner and shorter, remove unnecessary initKextPreferences()

v2.0.4

• Make update timeout configurable so that we have a more looser/tigher control over the HWP request
