# Changelog

## v0.18.2

### Bug fixes
  * Fixed issue with included relationships - #351

## v0.18.1

### Bug fixes
  * Fixed warnings in Elixir 1.17

## v0.18.0

### Breaking
  * Fixed warning in Elixir 1.14 for using Application.get_env/3 in module body.
    This required Application.compile_env/3 which is only available in Elixir 1.10+

## v0.17.0

### Breaking
  * Empty relationships with links are now handled properly. Instead of
    returning a relationship resource with a broken link, we now remove the
    broken links from the serialized "relationships" key. - #340

### Bug fixes
  * Allow "import" to be used as a relationship name - #336

## v0.16.0

### Breaking
  * Bump dependencies and remove support for Elixir < 1.7
  * Raise exception when using a reserved keyword in attributes/1 macro
  * Removed JaSerializer generators in favor of documenting how to use with
    Phoenix generators.

## v0.15.0

### Features
  * Add optional support for camelCase key format as recommended by
    JSON:API v1.1 - #316/#317
  * Make JaSerializer.TopLevel.Builder.normalize_includes/1 public - #323

### Bug fixes
  * Allow accept header with quality param - #320
  * Include relationships in sparse field definition - #324

### Breaking
  * Don't render empty relationships - #311
  * Omit prev/next links when current page is > last page - #317
  * Don't raise AssociationNotLoadedError if belongs to relationship can
    be determined. - #322

The following workaround is no longer needed:

```
has_one :city, serializer: MyApp.CityView

def city(%{city: %Ecto.Association.NotLoaded{}, city_id: nil}, _conn), do: nil
def city(%{city: %Ecto.Association.NotLoaded{}, city_id: id}, _conn), do: %{id: id}
def city(%{city: city}, _conn), do: city
```

## v0.14.1

### Bug fixes
  * Fix application start up w/out Poison - #310

## v0.14.0

### Breaking
  * Only include attributes key when there are attributes present - #297
  * Serializer attribute and relationship function overrides must be public.
  Previously there was an untested/undocumented way of overriding attributes with
  private functions, but this is no longer supported.

In other words, change this:

```
defmodule PostSerializer do
  use JaSerializer, dsl: true
  attributes [:html]

  defp html(post, _conn) do
    Earmark.to_html(post.body)
  end
end
```

to this:

```
defmodule PostSerializer do
  use JaSerializer, dsl: true
  attributes [:html]

  def html(post, _conn) do
    Earmark.to_html(post.body)
  end
end
```
