⚡ Performance & Enhancements (1)

  • We've written a blog post about the 300% increase in proxy performance delivered in 3.3.0.

🔧 Bug Fixes & Patches (6)

  • Cypress no longer accidentally prints internal Electron logs when running `cypress run`. This bug would exhibit itself when verifying and running Cypress the first time after installation. You may have seen these logs when running in CI. Fixes #4255.
  • Fixed a bug for users running external network proxies that prevented requests from completing. Requests should now all work correctly. Fixes #4257.
  • Fixed a regression in 3.3.0 causing large requests such as `multipart/form-data` uploads to hang. Fixes #4240, #4252, and #4253.
  • Fixed issue where support for `have.focus`, `not.have.focus`, `be.focused` and `not.be.focused` assertions were not working. Fixes #4265.
  • Names given to .as() now work properly when they contain a `.` character. Fixes #3512.
  • The proper error is now thrown when passing `{log: false}` to a Cypress command that failed. Fixes #3847.
