Introduced in branch: 
11.3.x
Introduced in version: 
11.3.0
Description: 

By optimizing how we handle Composite constraits from Symfony we no longer need AtLeastOneOfConstraintValidator that was introduced in 11.2.0 but moved to the default implementation from Symfony.

If you are using or extending the AtLeastOneOfConstraint this should not affect you. Only if you have custom validation logic in the extended class.
