# v1.0.0 to-be-released

### Added

* New `Repository#transaction` API for executing operations inside a database transaction (flash-gordon+solnic)
* `aggregate` and `combine` support nested association specs, ie `combine(users: [tasks: :tags])` (beauby)
* Changesets support data as arrays too (solnic)
* Changesets support custom command types via `Changeset#with(command_type: :my_command)` (solnic)
* `Changeset::Delete` was added and is accessible via `repo.changeset(delete: some_relation.by_pk(1))` (solnic)
* Ability to define custom changeset classes that can be instantiated via `repo.changeset(MyChangesetClass[:rel_name]).data(some_data)` or `root_repo.changeset(MyChangesetClass)` where `MyChangesetClass` inherits from a core changeset class (solnic)
* `Changeset.map` which accepts a block and exposes a DSL for data transformations (all [transproc hash methods](https://github.com/solnic/transproc)) are available (solnic)
* `Changeset.map` which accepts a custom block that can transform data (executed in the context of a changeset object) (solnic)
* Support for composing multiple mappings via `Changeset.map` (solnic)
* `Changeset#associate` method that accepts another changeset or parent data and an association identifier, ie `post_changeset.associate(user, :author)` (solnic)
* Support for inferring typed structs based on relation schemas (solnic)
* You can now use `wrap_parent` in combined relations too (which is gazillion times faster than `combine_parents`) (solnic)

### Changed

* `ROM::Struct` is now based on `Dry::Struct` (solnic)
* rom-support dependency was removed (flash-gordon)
* `update?` and `create?` methods were removed from `Changeset:*` subclasses (solnic)

### Fixed

* FKs are always included in auto-generated structs used in aggregates (solnic)
* Calling undefined methods on repo relations raises a nicer error (solnic)

# v0.3.1 2016-07-27

Fixed gemspec so that we don't exclude all files with 'bin' in their name, geez (solnic)

[Compare v0.3.0...v0.3.1](https://github.com/rom-rb/rom-repository/compare/v0.3.0...v0.3.1)

# v0.3.0 2016-07-27

### Added

* `Repository#command` for inferring commands automatically from relations (solnic)
* `Repository.commands` macro which generates command methods (solnic)
* `Repository[rel_name]` for setting up a repository with a root relation (solnic)
* `Repository#aggregate` as a shortcut for composing relation graphs from root (solnic)
* `Repository#changeset` API for building specialized objects for handling changes in relations (solnic)

### Fixed

* Auto-mapping includes default custom mapper for a given relation (AMHOL)
* When custom mapper is set, default struct mapper won't be used (AMHOL)

### Changed

* `Relation#combine` supports passing name of configured associations for automatic relation composition (solnic)
* `Repository` constructor simply expects a rom container, which makes it work with DI libs like `dry-auto_inject` (solnic)
* Depends on `rom 2.0.0` now (solnic)
* Replace anima with `ROM::Repository::StructAttributes` (flash-gordon)

[Compare v0.2.0...v0.3.0](https://github.com/rom-rb/rom-repository/compare/v0.2.0...v0.3.0)

# v0.2.0 2016-01-06

### Added

* You can now pass a custom class that will be used for mapping using `.as(MyClass)` interface (solnic)

### Changed

* Relation plugins have been moved to `rom` and `rom-sql`. Other adapters can
  enable them too which means repository can now be used *with any adapter* (solnic)
* `Repository::Base` is deprecated, just inherit from `ROM::Repository` (solnic)

## Fixed

* Added `respond_to_missing?` to `LoadingProxy` (AMHOL)
