-# How to release new crate versions
+Releasing new crate versions
+============================
+
+Releasing of [workspace] crates of this project is performed by pushing the Git release tag (having `<crate-name>@<version>` format), following by the [CI pipeline] creating a [GitHub release] and publishing the crate to [crates.io].
+
+> __WARNING__: Only one [workspace] crate may be released at a time. So, if you need to release multiple [workspace] crates, do this sequentially.
+
+
+

 ## Prerequisites

-It is generally best to start with a clean respository dedicated to a release so that no git weirdness happens:
-
-```
-git clone git@github.com:graphql-rust/juniper.git juniper_release;
-cd juniper_release;
+We use [`cargo-release`] to automate crate releases. You will need to install it locally:
+```bash
+cargo install cargo-release
 ```

-We use the `nightly` toolchain when releasing. This is because some of our crates require nightly:

-`rustup default nightly`

-We use [`cargo-make`](cargo-make) and [`cargo-release`](cargo-release) to automate crate releases. You will need to install them locally:

- `cargo install -f cargo-make`
- `cargo install -f cargo-release`
+## Preparing

-## Preparing for a release
+To produce a new release a [workspace] crate, perform the following steps:

-There are two general classes of releases:
+1. Check its `CHANGELOG.md` file to be complete and correctly formatted. The section for the new release __should start__ with `## master` header. Commit any changes you've made.

-1. All public workspace crates should be released and all share the same release level ("patch", "minor", "major").
+2. Determine a new release [bump level] (`patch`, `minor`, `major`, or default `release`).

-2. A subset of workspace crates need to be released, or not all crate releases share the same release level.
+3. Run the release process in dry-run mode and check the produced diffs to be made in the returned output.
+    ```bash
+    make release crate=juniper ver=minor
+    ```

-**All release commands must be run from the root directory of the repository.**
+4. (Optional) Not everything may be captured in dry-run mode. It may be a good idea to run a local test, without pushing the created Git commit and tag.
+    ```bash
+    make release crate=juniper ver=minor exec=yes push=no
+    ```

-## Determine new release level

-For each crate, determine the desired release level (`patch`, `minor`, `major`). Set the `RELEASE_LEVEL` env variable to the desired release level.

-## Determine which crates to release

-If a subset of workspace crates need to be released, or not all crate releases share the same release level, set the `CARGO_MAKE_WORKSPACE_INCLUDE_MEMBERS` env
-variable to choose specific workspace crates. The value is a list of semicolon-delineated crate names or a regular expressions.
+## Executing

-## Dry run
+Once everything is prepared and checked, just execute the releasing process:
+```bash
+make release crate=juniper ver=minor exec=yes
+```

-It is a good idea to do a dry run to sanity check what actions will be performed.
+Once the [CI pipeline] for the pushed Git tag successfully finishes, the crate is fully released.

- For case #1 above, run `cargo make release-dry-run`.
- For case #2 above, run `CARGO_MAKE_WORKSPACE_INCLUDE_MEMBERS="crate1;crate2" cargo make release-dry-run`.

-  If the command finishes super quickly with no output you likely did not set `RELEASE_LEVEL`.

-## Local test

-Not everything is captured in the dry run. It is a good idea to run a local test.
-In a local test, all the release actions are performed on your local checkout
-but nothing is pushed to Github or crates.io.
-
- For case #1 above, run `cargo make release-local-test`.
- For case #2 above, run `CARGO_MAKE_WORKSPACE_INCLUDE_MEMBERS="crate1;crate2" cargo make release-local-test`.
-
-  If the command finishes super quickly with no output you likely did not set `RELEASE_LEVEL`.
-
-After, your local git repository should have the changes ready to push to Github.
-Use `git rebase -i HEAD~10` and drop the new commits.
-
-## Release
-
-After testing locally and via a dry run, it is time to release. A release
-consists of bumping versions, starting a new changelog section, pushing a tag to Github, and updating crates.io. This should all be handled by running the automated commands.
-
- For case #1 above, run `cargo make release`.
- For case #2 above, run `CARGO_MAKE_WORKSPACE_INCLUDE_MEMBERS="crate1;crate2" cargo make release`.
-
-  If the command finishes super quickly with no output you likely did not set `RELEASE_LEVEL`,

+Juniper Book
+============
+
+Book containing the [`juniper`](https://docs.rs/juniper) user guide.
+
+
+
+
+## Contributing
+
+
+### Requirements
+
+The Book is built with [mdBook](https://github.com/rust-lang/mdBook).
+
+You may install it with:
+```bash
+cargo install mdbook
+```
+
+
+### Local test server
+
+To launch a local test server that continually re-builds the Book and auto-reloads the page, run:
+```bash
+mdbook serve
+
+# or from project root dir:
+make book.serve
+```
+
+
+### Building
+
+You may build the Book to rendered HTML with this command:
+```bash
+mdbook build
+
+# or from project root dir:
+make book
+```
+
+The output will be in the `_rendered/` directory.
+
+
+### Testing
+
+To run the tests validating all code examples in the book, run:
+```bash
+cd tests/
+cargo test
+
+# or from project root dir:
+cargo test -p juniper_book_tests
+
+# or via shortcut from project root dir:
+make test.book
+```
+
+
+
+
+## Test setup
+
+All Rust code examples in the book are compiled on the CI.
+
+This is done using the [skeptic](https://github.com/budziq/rust-skeptic) crate.

-## Security
-
- Fix panic on malformed queries with recursive fragments. *This is a potential denial-of-service attack vector.* Thanks to [@quapka](https://github.com/quapka) for the detailed vulnerability report and reproduction steps.
-
-## Breaking Changes
-
- Replaced `Visitor` associated type with `DeserializeOwned` requirement in `ScalarValue` trait. ([#985](https://github.com/graphql-rust/juniper/pull/985))
- Removed `Serialize` implementation from `#[derive(GraphQLScalarValue)]`macro, now should be provided explicitly. ([#985](https://github.com/graphql-rust/juniper/pull/985))
- `#[graphql_object]` and `#[graphql_subscription]` macros expansion now preserves defined `impl` blocks "as is" and reuses defined methods in opaque way. ([#971](https://github.com/graphql-rust/juniper/pull/971))
- `rename = "<policy>"` attribute's argument renamed to `rename_all = "<policy>"`. ([#971](https://github.com/graphql-rust/juniper/pull/971))
- Upgrade `bson` feature to [2.0 version of its crate](https://github.com/mongodb/bson-rust/releases/tag/v2.0.0). ([#979](https://github.com/graphql-rust/juniper/pull/979))
- Make `FromInputValue` methods fallible to allow post-validation. ([#987](https://github.com/graphql-rust/juniper/pull/987))
- Change `Option` to `Result` in `from_input_value()` return type of `#[graphql_scalar]` macro. ([#987](https://github.com/graphql-rust/juniper/pull/987))
- Forbid `__typename` field on `subscription` operations [accordingly to October 2021 spec](https://spec.graphql.org/October2021/#note-bc213). ([#1001](https://github.com/graphql-rust/juniper/pull/1001), [#1000](https://github.com/graphql-rust/juniper/pull/1000))
- Redesign `#[graphql_interface]` macro: ([#1009](https://github.com/graphql-rust/juniper/pull/1009))

-## Features
-
- Added async support. ([#2](https://github.com/graphql-rust/juniper/issues/2))
-  - `execute()` is now async. Synchronous execution can still be used via `execute_sync()`.
-  - Field resolvers may optionally be declared as `async` and return a future.
-
- Added *experimental* support for GraphQL subscriptions. ([#433](https://github.com/graphql-rust/juniper/pull/433))
-
- Added support for generating the [GraphQL Schema Language](https://graphql.org/learn/schema/#type-language) representation of a schema using `RootNode::as_schema_language()`. ([#676](https://github.com/graphql-rust/juniper/pull/676))
-  - This is controlled by the `schema-language` feature and is on by default. It may be turned off if you do not need this functionality to reduce dependencies and speed up compile times.
-  - Note that this is for generating the GraphQL Schema Language representation from the Rust schema. For the opposite--generating a Rust schema from a GraphQL Schema Language file--see the [`juniper_from_schema`](https://github.com/davidpdrsn/juniper-from-schema) project. 
-
- Most GraphQL spec violations are now caught at compile-time. ([#631](https://github.com/graphql-rust/juniper/pull/631))
-  - The enhanced error messages now include the reason and a link to the spec.
-    For example, if you try to declare a GraphQL object with no fields:
-    ```rust
-      error: GraphQL object expects at least one field
-     --> $DIR/impl_no_fields.rs:4:1
-      |
-    4 | impl Object {}
-      | ^^^^^^^^^^^^^^
-      |
-      = note: https://spec.graphql.org/June2018/#sec-Objects
-    ```
-
- [Raw identifiers](https://doc.rust-lang.org/edition-guide/rust-2018/module-system/raw-identifiers.html) are now supported in field and argument names.
-
- Most error types now implement `std::error::Error`. ([#419](https://github.com/graphql-rust/juniper/pull/419))
-  - `GraphQLError`
-  - `LexerError`
-  - `ParseError`
-  - `RuleError`
-
- Support `chrono-tz::Tz` scalar behind a `chrono-tz` feature flag. ([#519](https://github.com/graphql-rust/juniper/pull/519))
-
- Added support for distinguishing between between implicit and explicit null. ([#795](https://github.com/graphql-rust/juniper/pull/795))
-
- Implement `IntoFieldError` for `std::convert::Infallible`. ([#796](https://github.com/graphql-rust/juniper/pull/796))
-
- Allow using `#[graphql(Scalar = DefaultScalarValue)]` for derive macro `GraphQLScalarValue` ([#807](https://github.com/graphql-rust/juniper/pull/807))
-
-## Fixes
-
- Massively improved the `#[graphql_union]` proc macro. ([#666](https://github.com/graphql-rust/juniper/pull/666)):
-  - Applicable to traits.
-  - Supports custom resolvers.
-  - Supports generics.
-  - Supports multiple `#[graphql_union]` attributes.
-
- Massively improved the `#[derive(GraphQLUnion)]` macro. ([#666](https://github.com/graphql-rust/juniper/pull/666)):
-  - Applicable to enums and structs.
-  - Supports custom resolvers.
-  - Supports generics.
-  - Supports multiple `#[graphql]` attributes.
-
- Massively improved the `#[graphql_interface]` macro. ([#682](https://github.com/graphql-rust/juniper/pull/682)):
-  - Applicable to traits and generates enum or trait object to represent a GraphQL interface (see the [example of migration from `graphql_interface!` macro](https://github.com/graphql-rust/juniper/commit/3472fe6d10d23472752b1a4cd26c6f3da767ae0e#diff-3506bce1e02051ceed41963a86ef59d660ee7d0cd26df1e9c87372918e3b01f0)).
-  - Supports passing context and executor to a field resolver. 
-  - Supports custom downcast functions and methods.
-  - Supports generics.
-  - Supports multiple `#[graphql_interface]` attributes.
-    
- The `GraphQLEnum` derive now supports specifying a custom context. ([#621](https://github.com/graphql-rust/juniper/pull/621))
-  - Example:
-  ```rust
-  #[derive(juniper::GraphQLEnum)]
-  #[graphql(context = CustomContext)]
-  enum TestEnum {
-      A,
-  }
-  ```
-
- Added support for renaming arguments within a GraphQL object. ([#631](https://github.com/graphql-rust/juniper/pull/631))
-  - Example:
-  ```rust
-    #[graphql(arguments(argA(name = "test")))]
-  ```
-
- `SchemaType` is now public.
-  - This is helpful when using `context.getSchema()` inside of your field resolvers.
-
- Improved lookahead visibility for aliased fields. ([#662](https://github.com/graphql-rust/juniper/pull/662))
-
- When enabled, the optional `bson` integration now requires `bson-1.0.0`. ([#678](https://github.com/graphql-rust/juniper/pull/678))
-
- Fixed panic on `executor.look_ahead()` for nested fragments ([#500](https://github.com/graphql-rust/juniper/issues/500))
-
-## Breaking Changes
-
- `GraphQLType` trait was split into 2 traits: ([#685](https://github.com/graphql-rust/juniper/pull/685))
-  - An object-safe `GraphQLValue` trait containing resolving logic.
-  - A static `GraphQLType` trait containing GraphQL type information.
-
- `juniper::graphiql` has moved to `juniper::http::graphiql`.
-  - `juniper::http::graphiql::graphiql_source()` now requires a second parameter for subscriptions.
-
- Renamed the `object` proc macro to `graphql_object`.
- Removed the `graphql_object!` macro. Use the `#[graphql_object]` proc macro instead.
- Made `#[graphql_object]` macro to generate code generic over `ScalarValue` by default. ([#779](https://github.com/graphql-rust/juniper/pull/779))
-
- Renamed the `scalar` proc macro to `graphql_scalar`.
- Removed the `graphql_scalar!` macro. Use the `#[graphql_scalar]` proc macro instead.
-
- Removed the deprecated `ScalarValue` custom derive. Use `GraphQLScalarValue` instead.
-
- Removed the `graphql_interface!` macro. Use the `#[graphql_interface]` proc macro instead.
-
- Removed the `graphql_union!` macro. Use the `#[graphql_union]` proc macro or custom resolvers for the `#[derive(GraphQLUnion)]` instead.
-
- The `#[derive(GraphQLUnion)]` macro no longer generates `From` impls for enum variants. ([#666](https://github.com/graphql-rust/juniper/pull/666))
-  - Consider using the [`derive_more`](https//docs.rs/derive_more) crate directly.
-
- The `ScalarRefValue` trait has been removed as it was not required.
-
- Prefixing variables or fields with an underscore now matches Rust's behavior. ([#684](https://github.com/graphql-rust/juniper/pull/684))
-
- The return type of `GraphQLType::resolve()` has been changed to `ExecutionResult`.
-  - This was done to unify the return type of all resolver methods. The previous `Value` return type was just an internal artifact of 
-  error handling.
-
- Subscription-related: 
-  - Add subscription type to `RootNode`.
-  - Add subscription endpoint to `playground_source()`.
-  - Add subscription endpoint to `graphiql_source()`.
-
- Specifying a scalar type via a string is no longer supported. ([#631](https://github.com/graphql-rust/juniper/pull/631))
-  - For example, instead of `#[graphql(scalar = "DefaultScalarValue")]` use `#[graphql(scalar = DefaultScalarValue)]`. *Note the lack of quotes*.
-
- Integration tests:
-  - Renamed `http::tests::HTTPIntegration` as `http::tests::HttpIntegration`.
-  - Added support for `application/graphql` POST request.
-
- `RootNode::new()` now returns `RootNode` parametrized with `DefaultScalarValue`. For custom `ScalarValue` use `RootNode::new_with_scalar_value()` instead. ([#779](https://github.com/graphql-rust/juniper/pull/779))
-
- When using `LookAheadMethods` to access child selections, children are always found using their alias if it exists rather than their name. ([#662](https://github.com/graphql-rust/juniper/pull/662))
-  - These methods are also deprecated in favor of the new `LookAheadMethods::children()` method.

-
-### newtype ScalarValue derive
-
-See [#345](https://github.com/graphql-rust/juniper/pull/345).
-
-The newtype pattern can now be used with the `GraphQLScalarValue` custom derive
-to easily implement custom scalar values that just wrap another scalar,
-similar to serdes `#[serde(transparent)]` functionality.
-
-Example:
-
-```rust
-#[derive(juniper::GraphQLScalarValue)]
-struct UserId(i32);
-```
-
-### Other Changes

-
-[#333](https://github.com/graphql-rust/juniper/pull/333)
-
-### 2018 Edition
-
-All crates were refactored to the Rust 2018 edition.
-

-
-### Other changes
-
- The minimum required Rust version is now `1.34.0`.
- The `GraphQLType` impl for () was removed to improve compile time safefty. [#355](https://github.com/graphql-rust/juniper/pull/355)
- The `ScalarValue` custom derive has been renamed to `GraphQLScalarValue`.

-
-# [0.11.1] 2018-12-19

-## Changes
-
- The minimum required Rust version is now `1.30`.
- All macros and the custom derives now support the macro system changes properly
-  and also support Rust 2018 edition crates.
-
-  [#298](https://github.com/graphql-rust/juniper/pull/298)
-
-# [0.11.0] 2018-12-17
-
-## Changes
-
- The minimum required Rust version is now `1.30.0`.
-
-  [#271](https://github.com/graphql-rust/juniper/pull/271)
-
- Juniper is now generic about the exact representation of scalar values. This
-  allows downstream crates to add support for own scalar value representations.
-
-  There are two use cases for this feature:
-
-  - You want to support new scalar types not representable by the provided default
-    scalar value representation like for example `i64`
-  - You want to support a type from a third party crate that is not supported by juniper
-
-  **Note:** This may need some changes in down stream code, especially if working with
-  generic code. To retain the current behaviour use `DefaultScalarValue` as scalar value type
-
-  [#251](https://github.com/graphql-rust/juniper/pull/251)
-
- The `GraphQLObject` and `GraphQLEnum` derives will mark graphql fields as
-  `@deprecated` when struct fields or enum variants are marked with the
-  builtin `#[deprecated]` attribute.
-
-  The deprecation reason can be set using the `note = ...` meta item
-  (e.g. `#[deprecated(note = "Replaced by betterField")]`).
-  The `since` attribute is ignored.
-
-  [#269](https://github.com/graphql-rust/juniper/pull/269)
-
-* There is an alternative syntax for setting a field's _description_ and
-  _deprecation reason_ in the `graphql_object!` and `graphql_interface!` macros.
-
-  To **deprecate** a graphql field:
-
-  ```rust
-  // Original syntax for setting deprecation reason
-  field deprecated "Reason" my_field() -> { ... }
-
-  // New alternative syntax for deprecation reason.
-  #[deprecated(note = "Reason")]
-  field my_field() -> { ... }
-
-  // You can now also deprecate without a reason.
-  #[deprecated]
-  field my_field() -> { ... }
-  ```
-
-  To set the **description** of a graphql field:
-
-  ```rust
-  // Original syntax for field descriptions
-  field my_field() as "Description" -> { ... }
-
-  // Original syntax for argument descriptions
-  field my_field(
-    floops: i32 as "The number of starfish to be returned. \
-                    Can't be more than 100.",
-  ) -> {
-    ...
-  }
-
-  // New alternative syntax for field descriptions
-  /// Description
-  field my_field() -> { ... }
-
-  // New alternative syntax for argument descriptions
-  field my_field(
-    /// The number of starfish to be returned.
-    /// Can't be more than 100.
-    arg: i32,
-  ) -> {
-    ...
-  }
-
-  // You can also use raw strings and const &'static str.
-  //
-  // Multiple docstrings will be collapsed into a single
-  // description separated by newlines.
-  /// This is my field.
-  ///
-  /// Make sure not to filtz the bitlet.
-  /// Flitzing without a bitlet has undefined behaviour.
-  ///
-  #[doc = my_consts::ADDED_IN_VERSION_XYZ]

-# [0.10.0] 2018-09-13
-
-## Changes
-
- Changed serialization of `NaiveDate` when using the optional `chronos` support.
-
-  **Note:** while this is not a Rust breaking change, if you relied on the serialization format (perhaps by storing serialized data in a database or making asumptions in your client code written in another language) it could be a breaking change for your application.
-
-  [#151](https://github.com/graphql-rust/juniper/pull/151)
-
- The `GraphQLObject`, `GraphQLInputObject`, and `GraphQLEnum` custom derives will reject
-  invalid [names](http://facebook.github.io/graphql/October2016/#Name) at compile time.
-
-  [#170](https://github.com/graphql-rust/juniper/pull/170)
-
- Large integers (> signed 32bit) are now deserialized as floats. Previously,
-  they produced an "integer out of range" error. For languages that do not
-  have a distinction between integer and floating point types (such as
-  javascript), this meant large whole floating point values could not be
-  decoded (because they were represented without a fractional value such as `.0`).
-
-  [#179](https://github.com/graphql-rust/juniper/pull/179)
-
- The `GraphQLObject`, `GraphQLInputObject`, and `GraphQLEnum` custom derives
-  now parse doc strings and use them as descriptions. This behavior can be
-  overridden by using an explicit GraphQL `description` annotation such as
-  `#[graphql(description = "my description")]`. [View documentation](https://graphql-rust.github.io/types/objects/defining_objects.html#defining-objects).
-
-  [#194](https://github.com/graphql-rust/juniper/issues/194)
-
- Introduced `IntoFieldError` trait to allow custom error handling
-  i.e. custom result type. The error type must implement this trait resolving
-  the errors into `FieldError`. [View documentation](https://graphql-rust.github.io/types/objects/error_handling.html#structured-errors).
-
-  [#40](https://github.com/graphql-rust/juniper/issues/40)
-
- `GraphQLType` and `ToInputValue` are now implemented for Arc<T>
-
-  [#212](https://github.com/graphql-rust/juniper/pull/212)
-
- Error responses no longer have a _data_ field, instead, error details are stored in the _extensions_ field
-
-  **Note:** while this is a breaking change, it is a necessary one to better align with the latest [GraphQL June 2018](https://facebook.github.io/graphql/June2018/#sec-Errors) specification, which defines the reserved _extensions_ field for error details. [View documentation](https://graphql-rust.github.io/types/objects/error_handling.html#structured-errors).
-
-  [#219](https://github.com/graphql-rust/juniper/pull/219)
-
-* The `GraphQLObject` and `GraphQLInputObject` custom derives
-  now support lifetime annotations.
-
-  [#225](https://github.com/graphql-rust/juniper/issues/225)
-
-* When using the `GraphQLObject` custom derive, fields can now be omitted by annotating the field with `#[graphql(skip)]`. [View documentation](https://graphql-rust.github.io/types/objects/defining_objects.html#skipping-fields).
-
-  [#220](https://github.com/graphql-rust/juniper/issues/220)
-
-* Due to newer dependencies, the oldest Rust version supported is now 1.22.0
-
-  [#231](https://github.com/graphql-rust/juniper/pull/231)
-
-# [0.9.2] 2018-01-13
-
-## Changes
-
-### `__typename` for unions
-
-The [`__typename`](http://graphql.org/learn/queries/#meta-fields) query meta-field now works on unions.
-
-[#112](https://github.com/graphql-rust/juniper/issues/112)
-
-### Debug impls.
-
-http::GraphQLRequest now implements `Debug`.
-
-# [0.9.0] 2017-12-03
-
-## Changes
-
-This is the first release in a long time.
-Quite a few changes have accumulated since `0.8.1`, including multiple breaking
-changes.
-
-### Custom derive & macros
-
-Juniper has gained custom derive implementations for input objects, objects and
-enums.
-
- `#[derive(GraphQLInputObject)]`
- `#[derive(GraphQLEnum)]`
- `#[derive(GraphQLObject)]`
-
-The `graphql_enum!` and `graphql_input_object!` macros did not provide any more
-benefits, so they have been removed!
-All functionality is now covered by custom derive.
-Check the [docs](https://graphql-rust.github.io) to find out more.
-
-### Web framework integrations - Iron & Rocket
-
-The iron and rocket integrations were removed from the main crate, and are now
-available via the [juniper_iron](https://crates.io/crates/juniper_iron) and
-[juniper_rocket](https://crates.io/crates/juniper_rocket) crates.
-
-### FieldError rewrite (custom data)
-
-The `FieldError` type now supports custom data with the `Value` type from
-serde_json. Use this to populate the `data` field in returned errors.
-
-This also means that try! and `?` now work in resolvers, which is quite nice.
-
-Also, the `ResultExt` extension and the `jtry!` macro were removed, since they
-are redundant now!
-
-### Dynamic Schemas
-
-Juniper has gained support for dynamic schemas, thanks to @srijs.
-
-That also means the type of `RootNode` has changed to include a lifetime.
-
-The repository was restructured to a multi crate workspace to enable several new
-features like custom_derive and an extracted parser.
-
-#[#66](https://github.com/graphql-rust/juniper/pull/66)
-
-### Data Type Integrations
-
-Integrations with multiple popular crates was added to make working with them
-easier.
-
- uuid
- url
- chrono
-
-### Field Order
-
-To better comply with the specification, order of requested fields is
-now preserved.
-
-[#82](https://github.com/graphql-rust/juniper/issues/82
-
-### From/ToInputValue
-
-The `::from` and `::to` methods in `From/ToInputValue` were renamed to
-`from/to_input_value()` to not conflict with other methods.
-
-[#90](https://github.com/graphql-rust/juniper/pull/90)
-
-### Other changes
-
- Several small performance improvements
- Use [fnv](https://github.com/servo/rust-fnv) hash map for better performance

-# [0.8.1] – 2017-06-15
-
-Tiny release to fix broken crate metadata on crates.io.
-
-# [0.8.0] – 2017-06-15
-
-## Breaking changes
-
- To better comply with the specification, and to avoid weird bugs with very
-  large positive or negative integers, support for `i64` has been completely
-  dropped and replaced with `i32`. `i64` is no longer a valid GraphQL type in
-  Juniper, and `InputValue`/`Value` can only represent 32 bit integers.
-
-  If an incoming integer is out of range for a 32 bit signed integer type, an
-  error will be returned to the client.
-  ([#52](https://github.com/graphql-rust/juniper/issues/52),
-  [#49](https://github.com/graphql-rust/juniper/issues/49))
-
- Serde has been updated to 1.0. If your application depends on an older
-  version, you will need to first update your application before you can upgrade
-  to a more recent Juniper. ([#43](https://github.com/graphql-rust/juniper/pull/43))
-
- `rustc_serialize` support has been dropped since this library is now
-  deprecated. ([#51](https://github.com/graphql-rust/juniper/pull/51))
-
-## New features
-
- A new `rocket-handlers` feature now includes some tools to use the
-  [Rocket](https://rocket.rs) framework. [A simple
-  example](juniper_rocket/examples/rocket-server.rs) has been added to the examples folder.
-
-## Bugfixes
-
- A panic in the parser has been replaced with a proper error
-  ([#44](https://github.com/graphql-rust/juniper/pull/44))
-
-# [0.7.0] – 2017-02-26
-
-### Breaking changes
-
- The `iron-handlers` feature now depends on Iron 0.5
-  ([#30](https://github.com/graphql-rust/juniper/pull/30)). Because of
-  this, support for Rust 1.12 has been dropped. It might still work if
-  you're not using the Iron integrations feature, however.
-
-### New features
-
- Input objects defined by the `graphql_input_object!` can now be used
-  as default values to field arguments and other input object fields.
-
-# [0.6.3] – 2017-02-19
-
-### New features
-
- Add support for default values on input object fields
-  ([#28](https://github.com/graphql-rust/juniper/issues/28))
-
-# [0.6.2] – 2017-02-05
-
-### New features
-
- The `null` literal is now supported in the GraphQL
-  language. ([#26](https://github.com/graphql-rust/juniper/pull/26))
- Rustc-serialize is now optional, but enabled by default. If you
-  _only_ want Serde support, include Juniper without default features
-  and enable
-  Serde. ([#12](https://github.com/graphql-rust/juniper/pull/12))
- The built-in `ID` type now has a public constructor and derives a
-  few traits (`Clone`, `Debug`, `Eq`, `PartialEq`, `From<String>`,
-  `Deref<Target=str>`). ([#19](https://github.com/graphql-rust/juniper/pull/19))
- Juniper is now built and tested against all Rust compilers since
-  version 1.12.1.
-
-### Minor breaking change
-
- Serde has been updated to
-  0.9. ([#25](https://github.com/graphql-rust/juniper/pull/25))
-
-### Bugfixes
-
- The built-in GraphiQL handler had a bug in variable serialization.
-  ([#16](https://github.com/graphql-rust/juniper/pull/16))
- The example should now build and run without problems on
-  Windows. ([#15](https://github.com/graphql-rust/juniper/pull/15))
- Object types now properly implement
-  `__typename`. ([#22](https://github.com/graphql-rust/juniper/pull/22))
- String variables are now properly parsed into GraphQL
-  enums. ([#17](https://github.com/graphql-rust/juniper/pull/17))
-
-# [0.6.1] – 2017-01-06
-
-### New features
-
- Optional Serde support
-  ([#8](https://github.com/graphql-rust/juniper/pull/8))
-
-### Improvements
-
- The `graphql_input_object!` macro can now be used to define input
-  objects as public Rust structs.
- GraphiQL in the Iron GraphiQL handler has been updated to 0.8.1
-  (#[#11](https://github.com/graphql-rust/juniper/pull/11))
-
-### Minor breaking changes
-
-Some undocumented but public APIs were changed.
-
- `to_snake_case` correctly renamed to `to_camel_case`
-  ([#9](https://github.com/graphql-rust/juniper/pull/9))
- JSON serialization of `GraphQLError` changed to be more consistent
-  with how other values were serialized
-  ([#10](https://github.com/graphql-rust/juniper/pull/10)).
-
-# [0.6.0] – 2017-01-02
-
-TL;DR: Many big changes in how context types work and how they
-interact with the executor. Not too much to worry about if you're only
-using the macros and not deriving `GraphQLType` directly.
-
-### Breaking changes
-
- The `executor` argument in all resolver methods is now
-  immutable. The executor instead uses interior mutability to store
-  errors in a thread-safe manner.
-
-  This change could open up for asynchronous or multi-threaded
-  execution: you can today use something like rayon in your resolve
-  methods to let child nodes be concurrently resolved.
-
-  **How to fix:** All field resolvers that looked like `field name(&mut executor` now should say `field name(&executor`.
-
- The context type of `GraphQLType` is moved to an associated type;
-  meaning it's no longer generic. This only affects people who
-  implement the trait manually, _not_ macro users.
-
-  This greatly simplifies a lot of code by ensuring that there only
-  can be one `GraphQLType` implementation for any given Rust
-  type. However, it has the downside that support for generic contexts
-  previously used in scalars, has been removed. Instead, use the new
-  context conversion features to accomplish the same task.
-
-  **How to fix:** Instead of `impl GraphQLType<MyContext> for ...`,
-  you use `impl GraphQLType for ... { type Context = MyContext;`.
-
- All context types must derive the `Context` marker trait. This is
-  part of an overarching change to allow different types to use
-  different contexts.
-
-  **How to fix:** If you have written e.g. `graphql_object!(MyType: MyContext ...)` you will need to add `impl Context for MyContext {}`. Simple as that.
-
- `Registry` and all meta type structs now takes one lifetime
-  parameter, which affects `GraphQLType`'s `meta` method. This only
-  affects people who implement the trait manually.
-
-  **How to fix:** Change the type signature of `meta()` to read `fn meta<'r>(registry: &mut Registry<'r>) -> MetaType<'r>`.
-
- The type builder methods on `Registry` no longer return functions
-  taking types or fields. Due to how the borrow checker works with
-  expressions, you will have to split up the instantiation into two
-  statements. This only affects people who implement the `GraphQLType`
-  trait manually.
-
-  **How to fix:** Change the contents of your `meta()` methods to
-  something like this:
-
-  ```rust
-  fn meta<'r>(registry: &mut Registry<r>) -> MetaType<'r> {
-      let fields = &[ /* your fields ... */ ];
-
-      registry.build_object_type::<Self>(fields).into_meta()
-  }
-  ```

+
+### BC Breaks
+
+- [October 2021] GraphQL spec: ([#1000])
+    - Forbade [`__typename` field on `subscription` operations](https://spec.graphql.org/October2021#note-bc213). ([#1001])
+    - Supported `isRepeatable` field on directives. ([#1003])
+    - Supported `__Schema.description`, `__Type.specifiedByURL` and `__Directive.isRepeatable` fields in introspection. ([#1003])
+    - Supported directives on variables definitions. ([#1005])
+- Replaced `Visitor` associated type with `DeserializeOwned` requirement in `ScalarValue` trait. ([#985])
+- `#[graphql_object]` and `#[graphql_subscription]` expansions now preserve defined `impl` blocks "as is" and reuse defined methods in opaque way. ([#971])
+- Renamed `rename = "<policy>"` attribute argument to `rename_all = "<policy>"` (following `serde` style). ([#971])
+- Upgraded [`bson` crate] integration to [2.0 version](https://github.com/mongodb/bson-rust/releases/tag/v2.0.0). ([#979])
+- Made `FromInputValue` trait methods fallible to allow post-validation. ([#987])
+- Redesigned `#[graphql_interface]` macro: ([#1009])
+    - Removed support for `dyn` attribute argument (interface values as trait objects).
+    - Removed support for `downcast` attribute argument (custom resolution into implementer types).
+    - Removed support for `async` trait methods (not required anymore).
+    - Removed necessity of writing `impl Trait for Type` blocks (interfaces are implemented just by matching their fields now).
+    - Forbade default implementations of non-ignored trait methods.
+    - Supported coercion of additional `null`able arguments and return sub-typing on implementer.
+    - Supported `rename_all = "<policy>"` attribute argument influencing all its fields and their arguments. ([#971])
+- Split `#[derive(GraphQLScalarValue)]` macro into: 
+    - `#[derive(GraphQLScalar)]` for implementing GraphQL scalar: ([#1017]) 
+        - Supported generic `ScalarValue`.
+        - Supported structs with single named field.
+        - Supported overriding resolvers with external functions, methods or modules.
+        - Supported `specified_by_url` attribute argument. ([#1003], [#1000])
+    - `#[derive(ScalarValue)]` for implementing `ScalarValue` trait: ([#1025])
+        - Removed `Serialize` implementation (now should be provided explicitly). ([#985])
+- Redesigned `#[graphql_scalar]` macro: ([#1014])
+    - Changed `from_input_value()` return type from `Option` to `Result`. ([#987]) 
+    - Mirrored new `#[derive(GraphQLScalar)]` macro.
+    - Supported usage on type aliases in case `#[derive(GraphQLScalar)]` isn't applicable because of [orphan rules].
+- Renamed `ScalarValue::as_boolean` method to `ScalarValue::as_bool`. ([#1025])
+- Reworked [`chrono` crate] integration GraphQL scalars according to [graphql-scalars.dev] specs: ([#1010])
+    - Disabled `chrono` [Cargo feature] by default.
+    - Removed `scalar-naivetime` [Cargo feature].

 ### Added

- Support for different contexts for different types. As GraphQL
-  schemas tend to get large, narrowing down the context type to
-  exactly what a given type needs is great for
-  encapsulation. Similarly, letting different subsystems use different
-  resources thorugh the context is also useful for the same reasons.
+- Usage of Rust arrays as GraphQL lists. ([#966], [#918])
+- `From` implementations for `InputValue` mirroring the ones for `Value` and better support for `Option` handling. ([#996])
+- `null` in addition to `None` for creating `Value::Null` in `graphql_value!` macro (following `serde_json::json!` style). ([#996])
+- `graphql_input_value!` and `graphql_vars!` macros. ([#996])
+- [`time` crate] integration behind `time` [Cargo feature]. ([#1006])
+- `#[derive(GraphQLInterface)]` macro allowing using structs as GraphQL interfaces. ([#1026])

-  Juniper supports two different methods of doing this, depending on
-  your needs: if you have two contexts where one can be converted into
-  the other _without any extra knowledge_, you can implement the new
-  `FromContext` trait. This is useful if you have multiple crates or
-  modules that all belong to the same GraphQL schema:
+### Changed

-  ```rust
-  struct TopContext {
-    db: DatabaseConnection,
-    session: WebSession,
-    current_user: User,
-  }
+- Made `GraphQLRequest` fields public. ([#750])

-  struct ModuleOneContext {
-    db: DatabaseConnection, // This module only requires a database connection
-  }
+## Fixed

-  impl Context for TopContext {}
-  impl Context for ModuleOneContext {}
+- Unsupported spreading GraphQL interface fragments on unions and other interfaces. ([#965], [#798])
+- Unsupported expressions in `graphql_value!` macro. ([#996], [#503])
+- Incorrect GraphQL list coercion rules: `null` cannot be coerced to an `[Int!]!` or `[Int]!`. ([#1004])

-  impl FromContext<TopContext> for ModuleOneContext {
-    fn from(ctx: &TopContext) -> ModuleOneContext {
-      ModuleOneContext {
-        db: ctx.db.clone()
-      }
-    }
-  }

-  graphql_object!(Query: TopContext |&self| {
-    field item(&executor) -> Item {
-      executor.context().db.get_item()
-    }
-  });

-  // The `Item` type uses another context type - conversion is automatic
-  graphql_object!(Item: ModuleOneContext |&self| {
-    // ...
-  });
-  ```

-  The other way is to manually perform the conversion in a field
-  resolver. This method is preferred when the child context needs
-  extra knowledge than what exists in the parent context:

-  ```rust
-  // Each entity has its own context
-  struct TopContext {
-    entities: HashMap<i32, EntityContext>,
-    db: DatabaseConnection,
-  }
+## Previous releases

-  struct EntityContext {
-    // fields
-  }
+See [old CHANGELOG](/../../blob/juniper-v0.15.9/juniper/CHANGELOG.md).

-  impl Context for TopContext {}
-  impl Context for EntityContext {}

-  graphql_object!(Query: TopContext |&self| {
-    // By returning a tuple (&Context, GraphQLType), you can tell the executor
-    // to switch out the context for the returned value. You can wrap the
-    // tuple in Option<>, FieldResult<>, FieldResult<Option<>>, or just return
-    // the tuple without wrapping it.
-    field entity(&executor, key: i32) -> Option<(&EntityContext, Entity)> {
-      executor.context().entities.get(&key)
-        .map(|ctx| (ctx, executor.context().db.get_entity(key)))
-    }
-  });

-  graphql_object!(Entity: EntityContext |&self| {
-    // ...
-  });
-  ```

-### Improvements
-
- Parser and query execution has now reduced the allocation overhead
-  by reusing as much as possible from the query source and meta type
-  information.
-
-# [0.5.3] – 2016-12-05
-
-### Added
-
- `jtry!`: Helper macro to produce `FieldResult`s from regular
-  `Result`s. Wherever you would be using `try!` in a regular function
-  or method, you can use `jtry!` in a field resolver:
-
-  ```rust
-  graphql_object(MyType: Database |&self| {
-    field count(&executor) -> FieldResult<i32> {
-      let txn = jtry!(executor.context().transaction());
-
-      let count = jtry!(txn.execute("SELECT COUNT(*) FROM user"));
-
-      Ok(count[0][0])
-    }
-  });
-  ```
-
-### Changes
-
- Relax context type trait requirements for the iron handler: your
-  contexts no longer have to be `Send + Sync`.
-
- `RootNode` is now `Send` and `Sync` if both the mutation and query
-  types implement `Send` and `Sync`.
-
-### Bugfixes
-
- `return` statements inside field resolvers no longer cause syntax
-  errors.
-
-## 0.5.2 – 2016-11-13
-
-### Added
-
- Support for marking fields and enum values deprecated.
- `input_object!` helper macro
-
-### Changes
-
- The included example server now uses the simple Star Wars schema
-  used in query/introspection tests.
-
-### Bugfixes
-
- The query validators - particularly ones concerned with validation
-  of input data and variables - have been improved significantly. A
-  large number of test cases have been added.
-
- Macro syntax stability has also been improved. All syntactical edge
-  cases of the macros have gotten tests to verify their correctness.
