* Added a `composer-runtime-api` virtual package which you can require (as e.g. `^2.0`) to ensure things like the InstalledVersions class above are present. It will effectively force people to use Composer 2.x to install your project

- The new platform-check feature means that Composer checks the runtime PHP version and available extensions to ensure they match the project dependencies. If a mismatch is found, it exits with error details to make sure problems are not overlooked. To avoid issues when deploying to production it is recommended to run `composer check-platform-reqs` with the production PHP process as part of your build or deployment process.
- If a packages exists in a higher priority repository, it will now be entirely ignored in lower priority repositories.
