 ## DEV:
+- **[Add]**: Add `allowBlank` parameter to `isEmpty` string validator.
 - **[Add]**: Add `IntInput` as a specialized variant of GladeInput<int> which has additional, int related, validations such as `isBetween`, `isMin`, `isMax`
 - **[Add]**: Support skipping particular validation with `shouldValidate` callback.
 - **[Breaking]**: The `resetToPure` method on both GladeInput and GladeModel has been renamed to `setAsNewPure`. This change better reflects the method's behavior of setting a new pure state rather than resetting to the original state.
