-## 1.0.8 (September 6, 2016)
-- Update dependencies
-- Flowtype 0.32
-- Fix code style issues
-
-## 1.0.7 (August 15, 2016)
-- fix: babel build via the workaround https://phabricator.babeljs.io/T2877#78089 Huh, it's too tricky to use Map/Set in ES5.
-
-## 1.0.6 (August 13, 2016)
-- fix: babel build process
-
-## 1.0.5 (August 10, 2016)
-- Update packages, add `babel-plugin-transform-runtime` for build process. Fix [issue](https://github.com/nodkz/graphql-compose-connection/issues/2) for vanilla node.js users without babel (thanks @jacobbubu).
-
-## 1.0.4 (August 9, 2016)
-- Add `ofType` property to `Connection` and `Edge` types.
-Connection type is some kind of wrapper under GraphQLNamedType.
-This behavior needed for `graphql-compose` module in `projection` helper, otherwise, it incorrectly constructs projectionMapper for tricky fields.
-
-## 1.0.3 (July 22, 2016)
-- If `first` or `last` args not provided, then get first 20 records by default.
-
-## 1.0.2 (July 20, 2016)
-- fix: return non-empty PageInfo if records not found
-
-## 1.0.1 (July 18, 2016)
-* Add fallback to `sort` arg, due [unexpected behavior](https://github.com/graphql/graphql-js/issues/435#issuecomment-233297537) of defaultValue for enum field
-* Move `graphql-compose` module to peerDependencies.
-
-## 1.0.0 (July 15, 2016)
-* Production ready version
-
-## 0.0.1 (July 10, 2016)

 This is a plugin for [graphql-compose](https://github.com/graphql-compose/graphql-compose) family, which adds to the ObjectTypeComposer `connection` resolver.

+This package completely follows to Relay Cursor Connections Specification (<https://relay.dev/graphql/connections.htm>).
 
 Besides standard connection arguments `first`, `last`, `before` and `after`, also added significant arguments:
-* `filter` arg - for filtering records
-* `sort` arg - for sorting records. Build in mechanism allows sort by any unique indexes (not only by id). Also supported compound sorting (by several fields).

-Installation
-============
-```
+## Installation
+
+```bash
 npm install graphql graphql-compose graphql-compose-connection --save
 ```
 
 Modules `graphql` and `graphql-compose` are in `peerDependencies`, so should be installed explicitly in your app. They should not installed as submodules, cause internally checks the classes instances.

-Requirements
-============
+## Requirements
+
 Types should have following resolvers:
-* `count` - for counting records
-* `findMany` - for filtering records. Also required that this resolver supports search with operators (lt, gt), which used in `directionFilter` option. Resolver `findMany` should have `filter` argument, which will be copied to connection. Also should have `limit` and `skip` args.
