The primary goal of this release is to improve stability and consistency of the user experience. Many changes are designed to ensure the smoothest experience possible, as there have been some pitfalls you could easily run into as a new user. This includes ensuring you don’t run into issues such as your keyboard freaking out when turning on Tachyon mode, or random keys not working when it turns on.
Incase you missed it, the v4.5.0 changelog:
Tachyon Focus mode will let you achieve 1ms latency on the Wooting Two HE and Lekker Edition.
Applies to the Wooting Two HE and Wooting Two Lekker edition
Added option to control the behaviour of the Num Lock indicator
Can be found in Keyboard Settings
