8.0.28 is available via this link. It works completely fine for connecting to a live broker, can handle at least 1 Rithmic connection, and multiple Tradovate, CQG and most other available NT connections. It has full orderflow capability enabled. It's not the latest version, but is MultiPC, meaning you don't need a license, and it's not tied to any one hardware ID. Few people need the newer/newest copies of NT, unless a specific indicator uses some of the modified scripting they've introduced.
