 * Added `ember test --server` to run the `testem` command line server. `ember test --server` will automatically re-run your tests after a rebuild. [#474](https://github.com/stefanpenner/ember-cli/pull/474)
 * Add JSHinting for `app/` and `test/` trees when building in development. This generates console logs as well as QUnit tests (so that `ember test` shows failures). [#482](https://github.com/stefanpenner/ember-cli/pull/482)
 * Use the name specified in `package.json` while doing `ember init`. This allows you to use a different application name than your folder name. [#491](https://github.com/stefanpenner/ember-cli/pull/491)
+* Allow disabling live reload via `ember server --live-reload=false`. [#510](https://github.com/stefanpenner/ember-cli/pull/510)
