The keyword “2021” is crucial. While the base game was released in 2019/2020, the majority of quality-of-life improvements, stability fixes, and feature unlocks arrived via patches released throughout 2020 and early 2021. The last major, stable update that the scene widely adopted was released around April 2021 (patch version 1.1.2, depending on regional title ID).
