Lines 56 to 62 in 7ea0e6c

	var (
	FullAPIVersion0 = newVer(1, 5, 0)
	FullAPIVersion1 = newVer(2, 3, 0)
	MinerAPIVersion0 = newVer(1, 5, 0)
	WorkerAPIVersion0 = newVer(1, 7, 0)
	)

TIL about this, and it hasn't been bumped since 2022, and that's not great. IT should be bumped if the external API has been broken, added to, or something has been fixed about the way they work. Proper semver.
