 If no version range is specified with `cycjimmy/semantic-release-action@v3` then [semantic-release](https://github.com/semantic-release/semantic-release/) version [19.0.5](https://github.com/semantic-release/semantic-release/releases/tag/v19.0.5) is used. Earlier versions of `cycjimmy/semantic-release-action` default to using the latest version of [semantic-release](https://github.com/semantic-release/semantic-release/), so in this case it is recommended to specify version 19 or lower to avoid compatibility issues.
