4.4.0

Released Released on April 12, 2020

Features:

TypeScript test files are now supported without using special preprocessors plugins. Addresses #1859.

Bugfixes:

We fixed an issue where Cypress could crash with a This socket has been ended by the other party error when testing applications that make use of WebSockets. Fixes #6458.
Uncaught errors thrown from within application or test code now display their proper stack trace. Fixes #6964.
Assertion errors now include a stack trace that includes the calling code. Fixes #6969.
We now clone the options object passed into Cypress commands so that they're not mutated and receive the proper options. Fixes #3171.
We fixed an issue where invalid Set-Cookie values could cause requests to fail with a cannot read property key of undefined error. Now, invalid Set-Cookie values will be ignored. Fixes #6890.

Misc:

Cypress no longer hides output from cypress --version, cypress version, cypress cache path, or cypress cache list commands when npm log level is silent or warn. Addresses #2705.
The cy.task() error message is now more specific about the promise resolution value required. Addresses #6241.
