New Features

• Introducing Burst mode.

var screenShotOptions = new ScreenshotOptions ; await page.GoToAsync("https://www.google.com"); for(var x = 0; x < 100; x++) { await page.ScreenshotBase64Async(screenShotOptions); } await page.SetBurstModeOffAsync();

New APIs

• ScreenshotOptions.BurstMode and Page.SetBurstModeOff.
• Browser.Target.
• ConnectOptions/LaunchOptions.Transport and ConnectionOptions/LaunchOptions.EnqueueTransportMessages.
• Frame.GoToAsync

Breaking Changes

Evaluate changes

EvaluateFunctionAsync and EvaluateExpressionAsync won't try to infer the output type when used without generics. It will return a ** JToken** instead.

A piece of code like this:

int x = page.EvaluateExpressionAsync("1");

Will need to be replaced by one of these two options:

int x = page.EvaluateExpressionAsync("1"); int x = page.EvaluateExpressionAsync("1").ToObject();
