1.10.0

This release increases the minimum supported version of composer to v2 (currently in alpha,
but you should REALLY try it out).

By doing so, the code has been massively reduced, and a few relevant bugs around the detected
installed package versions have been squished in the process.

In order to upgrade, you must first have composer v2 installed, which you can get by runnning
its self-update tooling: composer self-update --2.
