What's new in this version:

- CPU:OCCT: Added instruction set to test summary in the UI
- CPU:LINPACK: Fixed a critical bug with Linpack parsing on CPUs with a huge number of cores - false positives were reported in some (thankfully rare) cases
- CPU:LINPACK: Improved test efficiency on CPU with lots of cores
- CPU:LINPACK: Removed the ability to specify memory in percent, as between 1GB and 8GB is best
- GPU:3D: No longer slows down when its window gets out of focus
- GPU:3D: Improved graphic card selection in multi-GPU configurations
- GPU:3D: Fixed a crash when GPU:3D has more than 30 sensors to display
- POWER SUPPLY: Switched to CPU:OCCT in small data set instead of Linpack
- MONITORING: The max temperature threshold can now be disabled/enabled with a checkbox and is disabled by default
- TESTING: Added a difference between "Cancelled" (triggers when a user closes GPU:3D's window for instance ) and "Crashed" (the test process terminated unexpectedly)
- Translations: Added Danish
- Translations: Added Korean
