Drupal 9.x compatibility

I'd like to help with this, as it would help me out on a project that I'm working on.
What needs done?
Dealing with a composer error when trying to install on D9.5

Problem 1
- drupal/cacheflush[1.0.0-beta1, ..., 1.0.0-beta4] require drupal/cacheflush_entity * -> found drupal/cacheflush_entity[dev-1.x, 1.0.0-alpha1, ..., 1.x-dev (alias of dev-1.x)] but it does not match your minimum-stability.
- Root composer.json requires drupal/cacheflush ^1.0@beta -> satisfiable by drupal/cacheflush[1.0.0-beta1, 1.0.0-beta2, 1.0.0-beta3, 1.0.0-beta4].

Thank you.

The Drupal 9 version of the latest 2.0.x branch is full featured working. We are working on the next Drupal 10.x readiness issues currently. Thank you.

I close the issue as Done.
