variationcache 8.x-1.5

Still the end of the line

VariationCache is now part of Drupal core 10.2 and up. This release keeps it working on D10.0 and D10.1 but also makes it so it does not collide with D10.2 and actually uses the core classes by virtue of class_alias(). It improves upon 1.4 in that some edge cases regarding kernel events now also work.

Once you upgrade to Drupal 10.2 and none of your code still refers to the Drupal/variationcache namespace, it is safe and recommended to turn off and remove this module.
