v1.1.0
This release adds the Rust version as reported by cargo
to the cache key.
This fixes a bug where the dependencies kept being re-compiled after a new Rust version has been released.
Background
Because newer Rust versions often contain performance optimizations, updating your Rust version will re-compile the dependencies.
If the dependencies were cached with an older Rust version, this will render the cache almost useless.
Including the Rust version in the cache key will result in the cache being re-generated as you update your Rust version and afterwards you should get fast CI again.
