# 1.0.0 2019-04-23
## Changed
-* `valid?` and `===` behave differently, `===` works the same way `Class#===` does and `valid?` checks if the value _can be_ coerced to the struct (flash-gordon)

## BREAKING CHANGES
-* `constructor_type` was removed, use `transform_types` and `transform_keys` as a replacement (see below)
-* Default types are evaluated _only_ on missing values. Again, use `tranform_types` as a work around for `nil`s
-* Values are now stored within a single instance variable names `@attributes`, this sped up struct creation and improved support for reserved attribute names such as `hash`, they don't get a getter but still can be read via `#[]`
-* Ruby 2.3 is a minimal supported version

## Added
-* `Dry::Struct.transform_types` accepts a block which is yielded on every type to add. Since types are `dry-types`' objects that come with a robust DSL it's rather simple to restore the behavior of `constructor_type`. See https://github.com/dry-rb/dry-struct/pull/64 for details (flash-gordon)
