# v0.7.2 2016-03-28

### Added

* Support for nested schemas inside high-level rules (solnic)
* `Schema#to_proc` so that you can do `data.each(&schema)` (solnic)

[Compare v0.7.1...v0.7.2](https://github.com/dryrb/dry-validation/compare/v0.7.1...v0.7.2)

# v0.7.1 2016-03-21

### Added

* You can use `schema` inside `each` macro (solnic)

### Fixed

* `confirmation` macro defines an optional key with maybe value with `_confirmation` suffix (solnic)
* `each` macro works correctly when its inner rule specify just one key (solnic)
* error messages for `each` rules where input is equal are now correctly generated (solnic)

### Changed

* Now depends on `dry-logic` >= `0.2.1` (solnic)

[Compare v0.7.0...v0.7.1](https://github.com/dryrb/dry-validation/compare/v0.7.0...v0.7.1)

# v0.7.0 2016-03-16

### Added

* Support for macros:
  * `required` - when value must be filled
  * `maybe` - when value can be nil (or empty, in case of `Form`)
  * `when` - for composing high-level rule based on predicates applied to a
    validated value
  * `confirmation` - for confirmation validation
* Support for `value(:foo).eql?(value(:bar))` syntax in high-level rules (solnic)
* New DSL for defining schema objects `Dry::Validation.Schema do .. end` (solnic)
* Ability to define a schema for an array via top-level `each` rule (solnic)
* Ability to define nested schemas via `key(:location).schema do .. end` (solnic)
* Ability to re-use schemas inside other schemas via `key(:location).schema(LocationSchema)` (solnic)
* Ability to inherit rules from another schema via `Dry::Validation.Schema(Other) do .. end` (solnic)
* Ability to inject arbitrary dependencies to schemas via `Schema.option` + `Schema#with` (solnic)
* Ability to provide translations for rule names under `%{locale}.rules.%{name}` pattern (solnic)
* Ability to configure input processor, either `:form` or `:sanitizer` (solnic)
* Ability to pass a constrained dry type when defining keys or attrs, ie `key(:age, Types::Age)` (solnic)
* `Result#messages` supports `:full` option to get messages with rule names, disabled by default (solnic)
* `Validation::Result` responds to `#[]` and `#each` (delegating to its output)
  and it's an enumerable (solnic)

### Changed

* `schema` was **removed** from the DSL, just use `key(:name).schema` instead (solnic)
* `confirmation` is now a macro that you can call on a key rule (solnic)
* rule names for nested structures are now fully qualified, which means you can
  provide customized messages for them. ie `user: :email` (solnic)
* `Schema::Result#params` was renamed to `#output` (solnic)
* `Schema::Result` is now `Validation::Result` and it no longer has success and
  failure results, only error results are provided (solnic)

### Fixed

* Qualified rule names properly use last node by default for error messages (solnic)
* Validation hints only include relevant messages (solnic)
* `:yaml` messages respect `:locale` option in `Result#messages` (solnic)

# v0.6.0 2016-01-20

### Added

* Support for validating objects with attr readers via `attr` (SunnyMagadan)
* Support for `value` interface in the DSL for composing high-level rules based on values (solnic)
* Support for `rule(name: :something)` syntax for grouping high-level rules under
  the same name (solnic)
* Support for `confirmation(:foo, some_predicate: some_argument)` shortcut syntax (solnic)
* Support for error messages for grouped rules (like `confirmation`) (solnic)
* Schemas support injecting rules from the outside (solnic)

## Changed

* `rule` uses objects that inherit from `BasicObject` to avoid conflicts with
  predicate names and built-in `Object` methods (solnic)
* In `Schema::Form` both `key` and `optional` will apply `filled?` predicate by
  default when no block is passed (solnic)

### Fixed

  errors and messages
