## [Unreleased]

## [1.3.7] - 2023-01-31

### Fixed

* Disable the stable access to the sparse registry.
    Setting the value causes problem on version before stabilization, e.g., 1.67.
    For example, "cargo add" fails.

## [1.3.6] - 2023-01-31

### Fixed

* The the correct environment variable to enable the sparse registry access.
    The pull request originally had the wrong value, without `CARGO_` prefix.

## [1.3.5] - 2023-01-21

### Changed

* Use the newly stabilized setting to enable sparse registry access.
    This speeds up access to the crate registry and is in addition to the unstable nightly env var.

## [1.3.4] - 2022-10-15

### Changed

## [1.3.3] - 2022-10-13

### Changed

* Switch from set-output to $GITHUB_OUTPUT to avoid warning

## [1.3.2] - 2022-09-15

## [1.3.0] - 2022-07-30

    Thanks to @filips123 for the PR.

## [1.2.1] - 2022-07-29

### Added

* Prefer toolchain definitions in `rust-toolchain` or `rust-toolchain.toml` files ([Toolchain File](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file)).
    Other input values are ignored if either file is found.
