+## 7.4.5
+
+* open sdk range to dart 2!
+* update built_value and source_gen dependencies
+* use SharedPartBuilder rather than PartBuilder in the generator
+
+## 7.4.4-dev
+
+* use typedef names in action generator
+
+## 7.4.3-dev
+
+* update dependency range on analyzer
+* update dependency range on test
+* fix broken test caused by dart 2's new asyc behavior
+
 ## 7.4.2
 
 * add lint ignores to generated files
 
+## 7.4.1-dev
+
+* open sourc-gen range
+* run tests on the dev compiler
+
 ## 7.4.1
 
 * fix cast issues around store changes in dart 2
 * open analyzer version range
 
+## 7.4.0-dev
+
+* add build.yaml and build.dart to comply with build_runner 0.7.x
+
+With the dev tag you can consume the latest versions of built_value, build, and build_runner that are only compatable with dart 2.
+
+In order to migrate:
+
+* remove your old build scripts
+* update your pubspec to include
+
+```yaml
+  build_runner: ^0.7.9
+```
+
+* add a build.yaml to the root of your repo that contains the following:
+
+```yaml
+targets:
+  $default:
+    builders:
+      built_value_generator|built_value:
+        enabled: false
+```
+
+* run `pub run build_runner build`.
+
+The build script is only a temporary measure until https://github.com/dart-lang/source_gen/issues/319 is resolved.
+
+
 ## 7.4.0
 
 * add built_redux_test_utils library - exposes an expectDispatched function for expecting a given action gets dispatched asynchronously

 built_redux is a state management library written in dart that enforces immutability.
 built_redux is not only an implementation of [redux][redux_git], but also a framework for building middleware and reducers in a type safe manner.
 
 Inspired by [redux][redux_git]
 
 Built using [built_value][built_value_git]
 
-## Using dart 2?
-Check out the [dart 2 dev branch](https://github.com/davidmarne/built_redux/tree/dart-2-dev), which works with the latest versions of build, build_runner, and built_value.

 # Setup
 
-built_value and built_redux both rely on code generation.
+built_value and built_redux both rely on build_runner for code generation.
 
 1. Add the `built_redux` package as a dependency in your `pubspec.yaml`.
+  
   ```yaml
   dependencies:
-    built_redux: ^7.0.0
-    built_value: ^5.0.0
+    built_redux: ^7.4.5
+    built_value: '>=5.5.5 <7.0.0'
   dev_dependencies:
-    build_runner: ^0.6.0
-    built_value_generator: '>=4.1.0 < 6.0.0'
-    source_gen: ^0.7.0
+    build_runner: ^0.9.0
+    built_value_generator: ^6.0.0
   ```
 
-2. Create a script to run generators for generating built_values and built_redux action classes.
-  ```dart
-  import 'dart:async';
-
-  import 'package:build_runner/build_runner.dart';
-  import 'package:built_value_generator/built_value_generator.dart';
-  import 'package:source_gen/source_gen.dart';
-  import 'package:built_redux/generator.dart';
-
-  Future main(List<String> args) async {
-    await build([
-      new BuildAction(
-          new PartBuilder([
-            new BuiltValueGenerator(),
-            new BuiltReduxGenerator(),
-          ]),
-          // your lib name here
-          'built_redux',
-          // tweak the files that invoke the generator here
-          inputs: const ['lib/**/*.dart'])
-    ], deleteFilesByDefault: true);
-  }
-  ```
-
-3. Run the build script from the command line to generate your built_values and built_redux action classes by running `dart [build script name].dart`
+2. Use build runner to build the generated files by executing `pub run build_runner build`
