## Executive Summary (TL;DR)
Cypress v2.1.0. Source highlight: Prevent a bug with `node-sass` on OSX + Windows when local `node` version does not match bundled `node` when importing components directly in spec files. The underlying issue was because we forgot to update `Buildkite` and `Appveyor` when we upgraded `Electron` in `2.0.0`. Fixes #1387 and #1390.

## Bug Fixes
- Prevent a bug with `node-sass` on OSX + Windows when local `node` version does not match bundled `node` when importing components directly in spec files. The underlying issue was because we forgot to update `Buildkite` and `Appveyor` when we upgraded `Electron` in `2.0.0`. Fixes #1387 and #1390.
- The Selector Playground has been updated to automatically prefer `data-cy`, `data-test` or `data-testid` attributes when providing the unique selector for an element. Additionally it now exposes a public API that you can use to control how it determines which selector to use. Fixes #1135.
