Composer 2.0, released on October 24, 2020, offers significant improvements over its predecessor, including up to 50% better performance in speed and memory usage for PHP dependency resolution. This update is particularly impactful given PHP's widespread use, with around 80% of websites incorporating PHP. Artifactory 7.24 supports the transition by accommodating both Composer v1 and v2 standards, allowing teams to migrate at their own pace while maintaining their existing Composer packages. Packagist, the primary PHP Composer registry, has deprecated Composer 1.x by reducing its metadata API update rate and restricting access to unused packages, encouraging developers to adopt Composer v2. Artifactory's new features, such as the Composer v2 metadata API and support for Drupal registries, facilitate seamless integration and improved performance. Users can enable or disable Composer v1 indexing in Artifactory configurations and are advised to update to the latest version of Artifactory to ensure compatibility and optimize package management services.
