This release upgrades ocramius/proxy-manager to use composer-runtime-api:^2: this means that you will need composer:^2 to install this version of ProxyManager.

In order to upgrade to composer v2, you can run composer self-update --2 on your development or CI/CD system.

In addition to that, few notable improvements:

• the ocramius/package-versions dependency has been replaced by composer-runtime-api
• testing and static analysis have been noticeably improved, making it easier for others to contribute to the project.
