What's new in this version:

Main:
- Added an auto-updater feature

Main:
- Lots of code cleanup and refactoring

Main:
- Workaround - Nvidia drivers apply G-sync to OCCT's GUI (which is pointless), which results in mouse stuttering

Ui:
- Revamped the settings screen and moved it into its separate section

Monitoring:
- Added Core usage monitoring section

Monitoring:
- Added a no monitoring option - the engine will still be started, but never updated to keep CPU usage low

Monitoring:
- Added a "Monitoring interval" settings, controlling how often should the monitoring be updated

Monitoring:
- Added a "Graph update" setting, controlling how often should the graphs be updated

Monitoring:
- Improved CPU Core usage sensor detection algorithm

Cpu:
- Fixed issues with core affinity on systems with more than 64 cores

Cpu:
- Added "Cycle" display in summary, which shows which cycle you are in. Each cycle uses different operands

Memory:
- Fixed various issues on systems with more than 64 cores

Gpu:
- You can now test simultaneously several GPUs, even of different brands (no SLI/Crossfire required)

Power:
- You can now test simultaneously several GPUs, even of different brands (no SLI/Crossfire required)

Enterprise:
- Added a new program "OcctCmd", to the enterprise edition - you can now run OCCT without any GUI, using a full command line interface (supports running tests only, there's no way to replicate OCCT's GUI in command line)

Enterprise:
- Greatly improved the report generation speed at the end of a long test
