Semver rule 4 specifies that 0.x.z, anything may change at anytime

[nishtala]

Semver rule #4 (https://semver.org/#spec-item-4) specifies that "
Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.
"
The text currently says you can get the latest patch release that will still compile, which is incorrect for x.y.z | (x==0)

Rust has a slightly stricter interpretation than SemVer does—specifically, the Cargo resolver handles Default Requirements like this:

Default requirements specify a minimum version with the ability to update to [SemVer] compatible versions.
Versions are considered compatible if their left-most non-zero major/minor/patch component is the same.
This is different from [SemVer] which considers all pre-1.0.0 packages to be incompatible.
