✨ New Features & Capabilities (2)

  • Added `Configuration API`
  • Added `Recipes`

🔧 Bug Fixes & Patches (6)

  • Plugins can now return a `Promise` and modify the yielded `config` to set new configuration values and environment variables. Fixes #1042 and #909 and #576.
  • There is a new `userAgent` option in `cypress.json`. This enables you to change the `userAgent` of the browser for the entire browsing session. Fixes #364.
  • There is a new `blacklistHosts` option in `cypress.json` that allows you to block requests made to those hosts. Blocked requests will respond with a `503` status code. This is useful for blocking 3rd party domains like Google Analytics. We have added a new recipe demonstrating this. Fixes #442.
  • Added chai assertions in TypeScript to generate autocompletion. Fixes #1073.
  • Updated TypeScript definitions to more accurately match the current Cypress API. Fixes #1050. Also note that if you were extending Cypress in TypeScript the `Chainer` interface changed. Please read 1048#issuecomment-351891910 to understand what you will need to update.
  • Renamed `environmentVariables` to `env` in the Desktop GUI. Fixes #1052.
