go only officially supports the two most recent minor versions: 1.20 and 1.21; 1.21 just released (1.20.0) so 1.20 will be supported for 6 more months, until 1.22 releases.
Go has had no breaking changes since the previous release used, 1.17 however it has added a new syntax for generics in 1.18.

Go does very well keeping code written in older versions working: https://tip.golang.org/doc/go1compat
