// Version for Go-compiled builds that didn't go through goreleaser.
//
// This is mostly here to make sure that people that use `go get` don't
// have a completely broken experience. It controls:
//
// 1) The version data you see when you run `tilt version`
// 2) The web JS you download when you're in web-mode prod.
//
// For distributed binaries, version is automatically baked
// into the binary with goreleaser. If this doesn't get updated
// on every release, it's often not that big a deal.
