What's new in this version:

- Changed the recommended "optimal" congestion control algorithm from CTCP to CUBIC for newer Windows 10 and Server 2019 builds. CUBIC works slightly better for pure throughput, CTCP may work slightly better for VoIP and gaming in combination with ECN and lossy connections.
