 ## [Unreleased]
 
+## [2.0.0-rc.1] - 2018-12-13
+
+## What Changed?
+
+For details on the changes since 1.x, see the [`2.0.0-beta.1` release notes](
+https://github.com/typed-ember/ember-cli-typescript/releases/tag/v2.0.0-beta.1).
+
+### Fixed 🔧
+
+- Builds no longer hang if a changed TypeScript file did not trigger a TS rebuild (which can happen e.g. if it is not yet imported elsewhere).
+- Type-checking information now properly gets injected into the build pipeline for test builds as well as development and production builds.
+- Declaration maps now have test coverage to make sure they don't break.
+
+### Changed 💥
+
+- The build system now uses the `tsconfig.json` file's `paths` key to copy type definitions during precompile, rather than assuming Ember project structure.
+
+### Added ⭐️
+
+- The addon now checks to confirm you're using Ember CLI 3.5+, since the new approach to builds has serious performance problems with a local `tmp` directory.
+
+### Under the hood 🚗 
+
+- Bumped *many* dependency versions.
+- Set up Azure Pipelines configuration.
+- Updated internals to use TypeScript themselves.
+
+## Upgrading ⚙️
+
+```
+ember install ember-cli-typescript@next
