Package abandoned how to remove it?

One can normally find out what is depending on an outdated package with this command:

composer depends --tree jakub-onderka/php-console-color

In this case it might show something like this:

jakub-onderka/php-console-color v0.2
└──jakub-onderka/php-console-highlighter v0.4 (requires jakub-onderka/php-console-color ~0.2)
   └──psy/psysh v0.9.9 (requires jakub-onderka/php-console-highlighter 0.3.*|0.4.*)
      └──laravel/tinker v1.0.8 (requires psy/psysh 0.7.*|0.8.*|0.9.*)
         └──your/project (requires laravel/tinker ^1.0)

These packages are used by nunomaduro/collision which is a Laravel dependency.

The package creator Tweeted out the issue was fixed on April 4th 2020*

Therefore, a composer update should bring in the new version of collision without the dependency and remove the warning.

Please note: These packages may also be used by other composer packages you are using so there's no guarantee this will work.
