1.2.0

Features:

• 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 'Stubbing Google Analytics' recipe demonstrating this. Fixes #442.

• Added chai assertions in TypeScript to generate autocompletion. Fixes #1073.

Bugfixes:

• 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 issue #1048 to understand what you will need to update.

Misc:

• Renamed environmentVariables to env in the Desktop GUI. Fixes #1052.

• Cypress.config() now returns a complete set of configuration values. Fixes #509.
