The Used By feature shows a badge at the top of public repositories which indicates how many repositories are known to depend on a public package published by this repository. In repositories that publish multiple packages, repository administrators can now choose the package to display in the repository settings experience.
Publishing packages from a GitHub Action to GitHub Package Registry
You can now use a
`GITHUB_TOKEN` when publishing or installing a npm or Apache Maven package to GitHub Package Registry from a GitHub Action. You can also publish or install packages of any type to GitHub Package Registry from a GitHub Action using a Personal Access Token.
As of right now, only users and organizations who are part of the GitHub Package Registry Beta can publish packages.
