v4.0.0

Adds the concept of an optional :merge_strategy to Attribute.merge(). This is used to determine which value to take from when a value is present in both the attributes and params. The strategy can be set to :param_priority (default), or :attribute_priority.

The behavior before this release was attribute priority.

v3.0.1

Fixes an issue so that optional :map attributes not supplied in the params are now present in the validated attributes with nil values.

v3.0.0

Optional booleans that are not present now return nil instead of false. This makes it easier to detect if the value was present.

attribute :param1, :boolean, optional: true

If the intent is to use spec to coerce an optional property to only true/false, use default:

attribute :param1, :boolean, default: false

v2.0.0

Added metadata to the return value of input validation. See the validation metadata section in the readme for more information.

v1.2.2
