🔧 Bug Fixes & Patches (6)

We fixed a bug where `cypress run --headless` would not run Chrome-family browsers headlessly. Fixes #5949.
We fixed an issue where, on some systems with IPv4 and IPv6 enabled, Cypress would fail to connect to the Chrome DevTools Protocol while launching Chrome, leading to test failures. Fixes #5912.
The strict cookie validation added in 3.5.0 for `cy.setCookie()`, `cy.clearCookie()`, and `cy.getCookie()` has been removed. Fixes #5642.
We fixed a regression in 3.8.0 where using `.type()` on number inputs to type non-number characters or the `{enter}` special character would not type the correct value. Fixes #5968 and #5997.
Configuration values set from the plugin file now display with the correct background color in the Configuration panel in the Test Runner Settings. Fixes #6024.
We removed the 'Me' and 'An Organization' selections in the Test Runner when setting up a project to more closely match the Dashboard UI. This also fixes an edge case where a user with no default organizations could potentially be unable to set up a project. Fixes #5954.
