Amazon CloudWatch Synthetics now supports custom browser launch settings

CloudWatch Synthetics now supports customizing the default launch settings on the Chrome browser with a new minor runtime version, syn-nodejs-2.1. This allows for more flexibility in the canary launched browser settings such as viewport, setting chromium flags, and handling errors. With syn-nodejs-2.1, you can also configure canary scripts to not take screenshots on a canary step, thereby reducing costs, and avoiding screenshots for sensitive data.
