Go uses Minimum Version Selection (MVS) instead of a SAT solver. There are no ranges in any go dependency specifications. It's actually a very simple and elegant algorithm for dependency version selection
> Minimal version selection assumes that each module declares its own dependency requirements: a list of minimum versions of other modules. Modules are assumed to follow the import compatibility rule—packages in any newer version should work as well as older ones—so a dependency requirement gives only a minimum version, never a maximum version or a list of incompatible later versions.
That sounds like a non-starter. You almost never want to to unintentionally 'upgrade' to the next 'major' ver. There's also occasionally broken or hacked/compromised minor vers.
thankfully major versions in go have different names (module, module/v2, module/v3) enforced by tooling, so you'll never upgrade to the next major (except v0 -> v1).
