## [Unreleased]

## [0.6.0] - 2020-09-23

### Added

* `Flows::Plugin::Interface` basic implementation
* `Flows::SharedContextPipeline` simple sub-pipelines injection

### Changed

* `Flows::SharedContextPipeline` callbacks execution method is changed to `instance_exec` (previously was `.call`)

### Fixed

* `Flows::Plugin::DependencyInjector` and modules generated by `Flows::Util::InheritableSingletonVars::DupStrategy` now can be safely included several times in the inheritance chain

## [0.5.1] - 2020-06-29

### Fixed

* `Flows::SharedContextPipeline` wrap DSL failure in case of inheritance, [issue](https://github.com/ffloyd/flows/issues/18)

## [0.5.0] - 2020-05-18

### Added

* `Flows::SharedContextPipeline` wrap DSL, [issue](https://github.com/ffloyd/flows/issues/7)
* `Flows::Flow` routing integrity check on initialization
* `Flows::Plugin::OutputContract` skip contract DSL method
* `Flows::Plugin::Profiler` introduced. Report types: raw, tree and flat.

### Changed

* `Flows::SharedContextPipeline` callback API, [issue](https://github.com/ffloyd/flows/issues/6)
* `Flows::Util` modules API, [issue](https://github.com/ffloyd/flows/issues/11)
* `Flows::Contract::CaseEq` default error expanded to present more context

## [0.4.0] - 2020-04-21

### Added

* `Flows::Contract` - type contracts with specific transformation feature.
* `Flows::Flow` - fast and lightweight logic execution engine, designed for
  internal usage and library writers.
* `Flows::Plugin::DependencyInjector` - simple dependency injection plugin for your classes
* `Flows::Plugin::ImplicitInit` - allows to use `MyClass.call` instead of
  `MyClass.new.call`, an class instance will be created once.
* `Flows::Plugin::OutputContract` - plugin for output type checks and
  transformations for service objects which return `Flows::Result`.
* `Flows::Railway` - stupid simple implementation of the railway pattern.
* `Flows::Result` - general purpose Result Object designed after Rust Result type.
* `Flows::Result::Do` - do-notation for Result Objects.
* `Flows::SharedContextPipeline` - much more flexible adoption of the railway
  pattern for Ruby.
* `Flows::Util::InheritableSingletonVars` - allows to define behavior for
  singleton variables in the context of inheritance.
* `Flows::Util::PrependToClass` - allows to prepend some module to class even if
  target module did not included directly into class.
