## [0.3.1] - 2025-02-01

### Added

- **Non-null Field Support**: Added `:non_null` and `:nullable` options to `gql_object` and `gql_fields` macros
  - Fields can be marked as `non_null` by passing `non_null: [:field1, :field2]` option
  - The `:nullable` option takes precedence and can override fields marked as non-null
  - Non-null wrapping is automatically skipped for `input_object` types (input fields remain nullable)

## [0.3.0] - 2025-01-19

### Added

- **Association Support**: Automatic handling of Ecto schema associations (`has_one`, `has_many`, `belongs_to`) in GraphQL types

  - New `extract_associations/1` function in `EctoGraphql.SchemaHelper` to extract association metadata from Ecto schemas
  - Association fields are automatically generated with Dataloader resolvers in `gql_fields` macro
  - New `:include_associations` option for `gql_fields` (defaults to `true`)

- **Dataloader Integration**: Built-in support for Dataloader in generated schemas

  - `gql.gen.init` task now adds `dataloader` dependency to `mix.exs`
  - Generated root schema includes `context/1` function with Dataloader setup
  - Generated root schema includes `plugins/0` function with `Absinthe.Middleware.Dataloader`

- **Optional Dataloader Dependency**: Added `{:dataloader, "~> 2.0", optional: true}` as an optional dependency

### Changed

- Renamed `filter_by_name/2` to `filter_by_field_name/2` in `EctoGraphql.GqlFields` for clarity
- Input objects (`gql_input_object`) now automatically exclude association fields

### Fixed

- Resolved issue where association fields caused compilation errors in input object types
- Fixed Dataloader function availability by using fully qualified module path `Absinthe.Resolution.Helpers.dataloader/1`

## [0.2.0] - - 2025-01-09

### Added

- Initial release with `gql_object` and `gql_fields` macros
- `mix gql.gen` task for generating GraphQL types, schemas, and resolvers
- `mix gql.gen.init` task for initializing Absinthe in a Phoenix project
- Automatic type mapping from Ecto to GraphQL types
- Field filtering with `:only` and `:except` options
- Custom field support via `do` blocks
