ALT Composer 2.3 is ready for a release, and we need your help to help test it and report any regression. This release is special as it contains almost only big internal changes allowing us to modernize our PHP code: - Upgraded minimum supported PHP version from 5.3.2 to 7.2.5 - Upgraded symfony component dependencies from 2.8.x to 5.4.x - Added scalar parameter types where possible - Added return types where possible - Added declare(strict_types=1) We'd be very glad if anyone can try it out with their projects, and especially for people extending Composer in some way (plugin or other) to try it out. - Running `composer self-update --preview` will get you the 2.3.0-RC1 (if you are running PHP 7.2.5 or above) - Running `composer self-update --stable` will get you back on the latest 2.2 stable release if things broke. - Report any issues you encounter as a new issue specifying you tried the 2.3 RC and please include stack traces & repro details.
