## Executive Summary (TL;DR)
Cypress v0.12.6. Source highlight: *Released 11/29/2015*

## Bug Fixes
- Setup/Teardown code was not properly running on nested mocha `before`hooks which caused the error: `The XHR server is unavailable or missing...`. Fixes #80 and #86.
- Prevent accidental mutation of cy.server() options when cy.route() was provided options. Fixes #84 and #85.
- Cross-Origin requests are now proxied by Cypress. In other words their URL's are transparently rewritten which bypasses CORS problems. This is a quick fix which should satisfy most of the problems users were having with CORS requests. However there is a much bigger change coming in `0.14.0` where the entire proxy layer will be rewritten to accommodate CORS, `window.fetch` and `domain cookies` flawlessly. As it stands Cypress is prone to errors in complex setups.
