Terminable Loop Command

Terminable Loop Command 1.2.1

This small new patch was needed because we discovered that PHP official Docker images override the STOPSIGNAL directive, using SIGQUIT instead of SIGTERM when shutting down a container. Thanks to Gabriele Colombera for providing the PR.

Terminable Loop Command 1.2.0

This new minor release is a maintenance one, which drops support for older (and EOLed) PHP & Symfony versions; this allowed me to bump all the development dependencies and streamline the CI flow.
