+### ⚠️ WARNING: Breaking Changes! ⚠️
+
+The ProcessGraphQl was rewritten to use [webonyx/graphql-php][webonyx/graphql-php] instead of [youshido/graphql](http://github.com/youshido/graphql). There are also several deprecations regarding the built in page fields.
 
 - The following fields no longer will be available for Page object types.
-	- `find`
-	- `next`
-	- `prev`
-	- `rootParent`
-	- `siblings`
+  - `find`
+  - `next`
+  - `prev`
+  - `rootParent`
+  - `siblings`
 - Also an experimental `pages` field is no longer supported.
 - The lowest version of PHP is 7.1 is required.
 - If you had used a third-party module to support additional PW fields for GraphQL, then they are no longer going to work. You'll have to update them to use [webonyx/graphql-php][webonyx/graphql-php].
 - If you used `GraphqlFieldtypeMapMarker` module, you need to update it to the latest vesion available.
 
 ### 0.23.3
+

 ### 0.17.0
-This release introduces lots of changes to repository structure and development
-process.
-- The master branch no longer tracks the vendor directory. This means that it
-is not suitable as a ProcessWire module. Instead you need to use [latest release][latest-release]
-tags as a ProcessWire module. Release branches are a minified version of this
-module that includes everything needed and works out of the box. The master
-branch is used for development.
-- Now we have a Continious Integration implemented. [![Build Status][travis-ci-badge]][travis-ci]
-This means that people can contribute confidently by running test suite and
-be sure that nothing has broken and a pull-request will be merged.
-- `$ProcessGraphQL->executeGraphQL` now accepts `payload` & `variables` as an
-argument. This allows you to modify the payload from client and manually pass
-it to the module to meet your needs.
