# Changelog

#### v0.11.4
- findBreakingChanges utility (see #199)

#### v0.11.3
- StandardServer: Support non pre-parsed PSR-7 request body (see #202)

#### v0.11.2
- Bugfix: provide descriptions to custom scalars (see #181)

#### v0.11.1
- Ability to override internal types via `types` option of the schema (see #174).

## v0.11.0
This release brings little changes but there are two reasons why it is released as major version:

1. To follow reference implementation versions (it matches 0.11.x series of graphql-js)
2. It may break existing applications because scalar input coercion rules are stricter now:<br>
In previous versions sloppy client input could leak through with unexpected results. 
For example string `"false"` accidentally sent in variables was converted to boolean `true` 
and passed to field arguments. In the new version, such input will produce an error 
(which is a spec-compliant behavior).

Improvements: 
- Stricter input coercion (see #171)
- Types built with `BuildSchema` now have reference to AST node with corresponding AST definition (in $astNode property)
- Account for query offset for error locations (e.g. when query is stored in `.graphql` file)

#### v0.10.2
- StandardServer improvement: do not raise an error when variables are passed as empty string (see #156)

#### v0.10.1
- Fixed infinite loop in the server (see #153)

## v0.10.0
This release brings several breaking changes. Please refer to [UPGRADE](UPGRADE.md) document for details.

New features and notable changes:
- Changed minimum PHP version from 5.4 to 5.5
- Lazy loading of types without separate build step (see #69, see [docs](http://webonyx.github.io/graphql-php/type-system/schema/#lazy-loading-of-types))
- PSR-7 compliant Standard Server (see [docs](http://webonyx.github.io/graphql-php/executing-queries/#using-server))
- New default error formatting, which does not expose sensitive data (see [docs](http://webonyx.github.io/graphql-php/error-handling/))
- Ability to define custom error handler to filter/log/re-throw exceptions after execution (see [docs](http://webonyx.github.io/graphql-php/error-handling/#custom-error-handling-and-formatting))
- Allow defining schema configuration using objects with fluent setters vs array (see [docs](http://webonyx.github.io/graphql-php/type-system/schema/#using-config-class))
- Allow serializing AST to array and re-creating AST from array lazily (see [docs](http://webonyx.github.io/graphql-php/reference/#graphqlutilsast))
- [Apollo-style](https://dev-blog.apollodata.com/query-batching-in-apollo-63acfd859862) query batching support via server (see [docs](http://webonyx.github.io/graphql-php/executing-queries/#query-batching))
- Schema validation, including validation of interface implementations (see [docs](http://webonyx.github.io/graphql-php/type-system/schema/#schema-validation))
- Ability to pass custom config formatter when defining schema using [GraphQL type language](http://graphql.org/learn/schema/#type-language) (see [docs](http://webonyx.github.io/graphql-php/type-system/type-language/))

Improvements:
- Significantly improved parser performance (see #137 and #128)
- Support for PHP7 exceptions everywhere (see #127)
- Improved [documentation](http://webonyx.github.io/graphql-php/) and docblock comments
