What's New in Bag 2.6

Improvements to Optional Property Validation

Bag 2.6 improves validation of Optional properties.

This release changes the behavior of validation when Optionals are involved. Prior to this release, if your validation for an Optional field was a simple presence requirement (e.g. required, present), an Optional value would pass, whereas a type/format validator would fail.

After this change, unless you use the OptionalOr validator, Optional values are stripped from the validated values, allowing rules like required to fail as expected.

This is a minor backward incompatible change, but the behavior is now what would have been expected previously.
