# lukechampine.com/blake3
../../../lukechampine.com/blake3/blake3.go:302:16: invalid operation: 1 << i (shift count type int, must be unsigned integer)

This is a feature that was added in Go 1.13: https://golang.org/doc/go1.13#language

It's not a big deal to change it, but seeing as Go 1.14 is due out this month, I think it's fair to require Go 1.13.
