yarn-plugin-backstage

This yarn plugin adds a backstage: version protocol to yarn, which replaces specific version ranges for @backstage/ packages. The recommended mode of use is to set all versions strings to backstage:* in package.json, which causes all versions to be resolved based on the version of Backstage specified in backstage.json. This ensures that all @backstage/ packages always correspond to a single release, and removes the need for package.json files to change when upgrading to a new release.

This plugin is still under active development, and requires some further testing before we recommend it for general use.
