# see also: https://golang.org/doc/install/source

# Go <= 1.4: a C toolchain.
# 1.5 <= Go <= 1.19: a Go 1.4 compiler.
# 1.20 <= Go <= 1.21: a Go 1.17 compiler.
# 1.22 <= Go <= 1.23: a Go 1.20 compiler.
# Going forward, Go version 1.N will require a Go 1.M compiler, where M is N-2 rounded down to an even number. Example: Go 1.24 and 1.25 require Go 1.22.
