@SimonSapin maybe using wildcards could be better, to make less painful updates for servo?

In Cargo, gleam = "0.1" is equivalent to gleam = "^0.1" which is equivalent to gleam = ">=0.1 <0.2". So cargo update will automatically pick up 0.1.1, 0.1.2 etc when we publish them. If we follow SemVer, 0.2 means that there was a breaking change and we might not want to update automatically. I think this is what we want.

https://users.rust-lang.org/t/should-be-used-for-cargo-dependencies/313 has some more discussion.
