 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 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.

The action takes the project's npm, pnpm or Yarn package manager lock file, installs dependencies and caches these dependencies for future use. It then proceeds to run Cypress end-to-end tests with the built-in Electron browser and provides a test summary after completion.
