Problem/Motivation

Drupal 8 has been officially unsupported since November 2021 but the Scheduler module has so far continued to be compatible with Drupal 8. However, this needs to change because we can no longer support PHP7.4, due to #3546172: Add @Constraint annotation to validation plugins where the attributes syntax needs PHP8.

Drupal 8 does not run on PHP8 - see this failed Drupal 8 Composer job where the PHP version was set to 8.0 

Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - Root composer.json requires drupal/core-recommended ^8.9 -> satisfiable by drupal/core-recommended[8.9.0-beta1, ..., 8.9.x-dev].
    - composer/installers v1.7.0 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.6.0] but it does not match the constraint.
    - composer/semver[1.1.0, ..., 1.7.1] require php ^5.3.2 || ^7.0 -> your php version (8.0.28) does not satisfy that requirement.
    - drupal/core 8.9.20 requires php ^7.0.8 -> your php version (8.0.28) does not satisfy that requirement.
    - drupal/core-recommended[8.9.0-beta1, ..., 8.9.0-rc1] require composer/installers v1.7.0 -> satisfiable by composer/installers[v1.7.0].
    - drupal/core-recommended[8.9.0, ..., 8.9.x-dev] require composer/semver 1.5.1 -> satisfiable by composer/semver[1.5.1].
    - drupal/core-recommended 8.9.20 requires drupal/core 8.9.20 -> satisfiable by drupal/core[8.9.20].

Proposed resolution

Make a new release of 2.x will be the last to be compatible with Drupal 8.
