> Since rust crate version numbers without leading '^' sometimes leads to confusions, how about prepend the versions changed in this PR with '^' to make it more clear? @mqy -- I think it is common in rust projects (especially library crates like Arrow) to allow some flexibility in their dependencies and thus not prefix with `^`. Cargo claims to implement [semve](https://semver.org/) -- which I think means in theory crate publishers should take care and ensure that "non major version upgrades" (aka 1.2.1 --> 1.2.2, or 1.2.1 --> 1.3.0) don't contain breaking changes. If you use the `^` prefix we would prevent crates / projects that depend of Arrow from using anything other than the exact version specified. As you saw, the parquet-format crate didn't follow the semver versioning convention thus breaking our CI :( ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
