 - [#35](https://github.com/zendframework/zend-validator/pull/35) modifies the
   `NotEmpty` validator to no longer treat the float `0.0` as an empty value for
   purposes of validation.
+- [#25](https://github.com/zendframework/zend-validator/pull/25) fixes the
+  `Date` validator to check against `DateTimeImmutable` and not
+  `DateTimeInterface` (as PHP has restrictions currently on how the latter can
+  be used).
