You can apply them to a constraint, or just apply them to an empty constraint if you want to allow unstable packages of a dependency for example.

In most cases this is not required and should be omitted (see below).

Example: additionally support explicit references (i.e. commit) for dev versions to make sure they are locked to a given state, even when you run update.

These only work if you explicitly require a dev version and append the reference with Note: While this is convenient at times, it should not be how you use packages in the long term because it comes with a technical limitation.The metadata will still be read from the branch name you specify before the hash.Because of that in some cases it will not be a practical workaround, and you should always try to switch to tagged releases as soon as you can. The package will not be installed unless those requirements can be met.Lists packages required for developing this package, or running tests, etc.The dev requirements of the root package are installed by default.Both option that prevents dev dependencies from being installed.
