- Default Electron browser upgraded from Chromium 53 to 59, a breaking change that may affect test behavior.
- Introduced automatic removal of obstructive JavaScript (modifyObstructiveCode, true by default) and now clears the browser's disk cache on each run (future cy.clearCache API).
- Multiple bug fixes: blacklistHosts cache handling, spy/stub retry, basic auth handling in Chrome 63/64, spec path normalization, CI networking flag removal, UI improvements, and free tier now includes private projects.
