-1. New versions of this action will be released automatically by the CI when merged to the `master` branch, see [.github/workflows/main.yml](.github/workflows/main.yml). This will create a new [GitHub release](https://github.com/cypress-io/github-action/releases) and will update the current `v5` branch.

This will create a new [GitHub release](https://github.com/cypress-io/github-action/releases) and will update the current highest branch from the series `v5`, `v6`, ... etc. Thus specifying `uses: cypress-io/github-action@v6` (or higher version if available) selects the new version automatically. This **will not** push the latest release to GitHub Marketplace.
 1. The action's CI is configured to use the [default Angular release rules](https://github.com/semantic-release/commit-analyzer/blob/master/lib/default-release-rules.js). This means that only `feat:`, `fix:` and `perf:` trigger a new release which is then logged to the [releases](https://github.com/cypress-io/github-action/releases) page. Other Angular commit types listed on [Contributing to Angular](https://github.com/angular/angular/blob/main/CONTRIBUTING.md#-commit-message-format) can be used for documentation purposes, however they are ignored by the currently configured release process.
