Composer can't find the release

Hi, I was able to install the version 2.0@beta without any issues via composer. Can you try updating your composer and then again install as there sometimes can be version constraints.

>composer require drupal/viewsreference:2.0@beta
./composer.json has been updated
Running composer update drupal/viewsreference
Gathering patches for root package.
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires drupal/viewsreference 2.0@beta (exact version match), found drupal/viewsreference[dev-1.x, dev-2.x, 1.0.0-alpha1, ..., 1.x-dev (alias of dev-1.x), 2.0.0-alpha1, ..., 2.x-dev (alias of dev-2.x)] but it does not match the constraint.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

after about 15 tries, I found out that the correct name is " 2.0.0-beta1 "

You forgot the ^ character. It's trying to install an exact version otherwise, one that doesn't exist. The correct command can be found on the project page, you just need to copy it.

composer require 'drupal/viewsreference:^2.0@beta'

I tried both variants.
