🔧 Bug Fixes & Patches (6)

Fixed a regression caused in `3.1.1` where we attempted to set a property on an invalid cookie sent from a server. Fixes #2724.
Fixed Cypress not correctly aborting long running connections (such as server sent events) on proxied requests. Fixes #2612.
Fixed bug where tests were failing due to assertions causing Cypress to accidentally iterate through cross origin iframes. If you were seeing "random" cross origin errors, this likely fixes those issues. Fixes #2784.
Fixed incorrectly setting `charCode` and `keyCode` when using .type() on a few different special characters such as `{`. Fixes #2105.
Fixed another regression in `3.1.1` where passing `undefined` to a `setTimeout` caused Cypress to error. Fixes #2719.
Fixed a bug in node core where Cypress would not show up in `Windows` for users on `node >= 11`. Fixes #2667.
