0.15.1 - 2022-02-24

In this release a license generation step was fixed, which caused the automated binary builds to fail.
In addition, a Cargo feature toggle was added which adds a feature gate for the rust-dist release source of
the rust-releases crate. This allows people who build from source to build cargo-msrv without the default
features (i.e. without rust-dist), which reduces build time and binary size.

This release does not contain user-facing changes, hence the lack of changelog entries for this version.
