When not set, the action heuristically enables all features that are not unstable, nightly, or internal-only. Possible values: `all-features`, `default-features`, `only-explicit-features`. | |

 | `release-type`       | Sets the release type instead of deriving it from the version number specified in the `Cargo.toml` file. Possible values are `major`, `minor`, `patch`. | |
 | `rust-toolchain`     | Rust toolchain name to use, e.g. `stable`, `nightly` or `1.68.0`. It will be installed if necessary and used regardless of local overrides and the `rust-toolchain.toml` file. However, if the input is set to `manual`, the action assumes some Rust toolchain is already installed and uses the default one. | `stable` |
