Contao 3.5.15: Package Management does not update the installed packages. I also can't update "contao-community-alliance/composer" which stays at version 0.13.2. With each attempt to update I get the following message:
"The Composer\Package\LinkConstraint\VersionConstraint class is deprecated, use Composer\Semver\Constraint\Constraint instead."
Any help is appreciated.
