# Changelog
## 0.16.0 - 05.11.2020
### Breaking Changes
- signature changes:
- `render`:
`a -> Text`
to `a -> ByteString`
- parseTypeSystemDefinition :
`Text -> Eventless (Schema VALID)`
to `ByteString -> Eventless (Schema VALID)`
- parseTypeDefinitions:
`Text -> Eventless [TypeDefinition ANY CONST]`
to `ByteString -> Eventless [TypeDefinition ANY CONST]`
### new features
### Minor Changes
- parser performance optimization
## 0.15.1 - 12.09.2020
relaxed upper boundary of `megaparsec` up to 10.0.0
## 0.15.0 - 12.09.2020
### new features
- `render` renders SchemaDefinition e.g
```graphql
schema {
query: MyQuery
}
```
- query validator automatically adds `__typename` to interface types
- type : `App`
```hs
api :: a -> m b
api = runApp (mkApp schema resolvers)
```
- `App` supports semigroup(`schema Stitching`):
if whe have two apps `app1` and `app2` with type `Api EVENT IO` we can merge it as.
```hs
mergedApi :: a -> m b
mergedApi = runApp (app1 <> app2)
```
- `runApp` changed signature to:
```hs
runApp :: Api e m -> a -> m b
```
### Breaking Changes
- removed `runApi`.
### Minor Changes
- internal refactoring
## 0.14.1 - 16.08.2020
## 0.14.0 - 15.08.2020
### new features
- query validation supports interfaces
- exposed: `Data.Morpheus.Types.SelectionTree`
- configurable api: `Data.Morpheus.Core` exports
- `Config`
- `defaultConfig`
- `debugConfig`
- for better debugging, internal errors messages will display resolving state:
- `current TypeName`
- `current Selection`
- `OperationDefinition`
- `SchemaDefinition`
- rendering graphql "AST". e.g `render (selection :: Selection VALID)` will render
```graphql
{
user(arg1: 1) {
name
}
}
```
- quasiquoter `[dsl| <type definitions> |]` generates `Schema VALID`.
- parser supports custom directive definition. e.g
```graphql
directive @MyDirective on FIELD_DEFINITION | OBJECT
```
- directive Validation for Document (TypeSystem).
- supports of block string values. e.g:
```graphql
query {
createDeity(
name: """
power
bla \n sd
blu \\ date
"""
) {
name
}
}
```
- support of `schema`. issue #412
```graphql
schema {
query: MyQuery
}
```
### Breaking Changes
- `Context' renamed to`ResolverContext'
- removed : `EventCon` from `Data.Morpheus.Core`
- internal refactoring: changed AST.
Schema AST Types now need parameter `stage = RAW | CONST | VALID`.
- `Schema VALID`
- `TypeDefinition VALID`
- `FieldDefinition IN VALID`
- ...
- runApi requires argument config
```hs
runApi ::
Schema s ->
RootResModel event m ->
Config ->
GQLRequest ->
ResponseStream event m (Value VALID)
```
## 0.13.0 - 22.06.2020
### new features
- exposed: `Data.Morpheus.Types.GQLScalar`
- exposed: `Data.Morpheus.Types.ID`
- finished interface validation
- supports default values
## minor changes
- internal refactoring
- added dependency `mtl`
- validates strings as enum from JSON value
## 0.12.0 - 21.05.2020
## New features
- parser supports implements interfaces separated with empty spaces
```gql
type T implements A , B C & D {
```
- introspection can render interfaces
