So, when using composer we get:

Deprecation Notice: The Composer\Package\LinkConstraint\VersionConstraint class is deprecated, use Composer\Semver\Constraint\Constraint instead. in phar:///www/htdocs/w00ee986/webmail/composer.phar/src/Composer/Package/LinkConstraint/VersionConstraint.php:17
Deprecation Notice: The Composer\Package\LinkConstraint\LinkConstraintInterface interface is deprecated, use Composer\Semver\Constraint\ConstraintInterface instead. in phar:///www/htdocs/w00ee986/webmail/composer.phar/src/Composer/Package/LinkConstraint/LinkConstraintInterface.php:17
