4.9.0

Released Released on June 22, 2020

Features:

An animated progress bar now displays on every command in the Command Log indicating how long the command has left to run before reaching its command timeout. Addresses #7642.
There is now an experimentalFetchPolyfill configuration option. When this option is true, Cypress will automatically replace window.fetch with a polyfill that Cypress can spy on and stub. Addresses #7710.
You can now pass a --quiet flag to cypress run to silence any Cypress specific output from stdout. Addresses #7714.

Bugfixes:

cy.wait() now correctly resolves when waiting for XHR requests that contain resource-like text in the XHR's query params or hash (like .js, .html, .css). #7280.
We fixed a regression in 4.6.0 where errors thrown from the application under test as strings would not be correctly handled. Fixes #7590.
We fixed a regression in 4.8.0 where .click() would hang if the subject had a shadow root and experimentalShadowDomSupport was not enabled. Fixes #7679.
We fixed a regression in 4.6.0 so that .should('have.value') now properly asserts against <progress>, <meter> or <li> element's values. Fixes #7603.
Cypress no longer responds with 413 responses during a recorded cypress run when the stdout is too large. Fixes #7548.
We fixed an issue where Cypress could exit successfully even with failing tests when launched in global mode. Fixes #7755.
Assertion logs now properly display as parent commands in the Command Log regardless of what is in the beforeEach hook. Fixes #7731.
When experimentalShadowDomSupport is enabled, querying shadow dom in certain situations will no longer cause the error Cannot read property 'length' of undefined during cypress run. Fixes #7676.
Highlighting of elements upon hover of a command in the Command Log are now visible when targeting absolute positioned elements. Fixes #7762.
cypress run will no longer crash when provided an empty string to the --project flag. Fixes #7743.

Misc:

There is now a loading state to indicate when tests are loading in the Command Log. Addresses #7700.
The type definitions for fixturesFolder, pluginsFile, screenshotsFolders and videoCompression have been updated to allow false TypeScript types. Addresses #7654.
The type definitions for cy.wait(ms) now correctly yield the type of the previous subject. Addresses #7682.
The type definitions now allow for the 'key' keyword when chaining off 'any' or 'all' assertion chainers. Addresses #7665.
