Jordi Boggiano, co-founder of Packagist and lead developer of Composer, announced the release of version 1.3.0 of Composer. It has some great new features and added a workaround for the performance impact that is caused by running PHP with Xdebug enabled. Composer can update itself by running the
self-update command (see here in the documentation).
