Cypress v5.4.0 — Release Notes & Engineering Impact

*Released 10/14/2020* **Features:** - You can now run [`cypress cache prune`](https://on.cypress.io/command-line#cypress-cache-prune) to delete all installed Cypress versions from the cache except for the currently-installed version. Addresses [#5972](https://github.com/cypress-io/cypress/issues/5972). - There's a new `--size` option for the [`cypress cache list`](https://on.cypress.io/command-line#cypress-cache-list) command that prints the sizes of the Cypress cache folders. Addresses [#6404](https://github.com/cypress-io/cypress/issues/6404). - For video recordings of runs, there is now a video chapter key for each test. If your video player supports chapters, you can move to the start of each test right away. Addresses [#3626](https://github.com/cypress-io/cypress/issues/3626). - In Windows, you can now append the browser type to the end of the path passed to the `--browser` flag, like `cypress open --browser C:/User/App/browser.exe:chrome`, to help detect the browser type. Addresses [#6389](https://github.com/cypress-io/cypress/issues/6389). - [`cy.viewport()`](https://on.cypress.io/viewport) has new `iphone-7`, `iphone-8`, and `iphone-se2` presets. Addressed in [#8624](https://github.com/cypress-io/cypress/issues/8624) - When there is a new version of Cypress available, the update modal has a new design with 'copy to clipboard' buttons to copy the upgrade commands. Addressed in [#8751](https://github.com/cypress-io/cypress/issues/8751). - The [Command Log](https://on.cypress.io/test-runner#Command-Log) can be hidden by passing the `CYPRESS_NO_COMMAND_LOG=1` environment variable during `cypress open` or `cypress run` to be used as a tool to debug performance issues. Addressed in [#8689](https://github.com/cypress-io/cypress/issues/8689). **Bugfixes:** - We fixed a regression in [5.0.0](https://on.cypress.io/changelog-5-8-0) where the `chromeWebSecurity` option had no effect in Electron. Fixes [#8399](https://github.com/cypress-io/cypress/issues/8399). - Tests will no longer hang and now properly throw when there is an error thrown from a `test:after:run` event listener. Fixes [#2271](https://github.com/cypress-io/cypress/issues/2271) and [#8701](https://github.com/cypress-io/cypress/issues/8701). - When a command is chained after [`.within()`](https://on.cypress.io/within) and "`cy.get()`" is called inside it, the scope will no longer permanently change. Fixes [#2106](https://github.com/cypress-io/cypress/issues/2106), [#4672](https://github.com/cypress-io/cypress/issues/4672), [#4757](https://github.com/cypress-io/cypress/issues/4757), and [#5183](https://github.com/cypress-io/cypress/issues/5183). - Dual commands like [`cy.contains()`](https://on.cypress.io/contains) when used after an [`.each()`](https://on.cypress.io/each) commands now query as expected. Fixes [#4921](https://github.com/cypress-io/cypress/issues/4921). - `/` is no longer added to the URL when `baseUrl` has param(s). Fixes [#2101](https://github.com/cypress-io/cypress/issues/2101). - When using [`cy.route2()`](https://on.cypress.io/route2) the route handler timeouts will no longer leak into other tests and cause random failures. Addressed in [#8727](https://github.com/cypress-io/cypress/issues/8727). - Re-running failed build steps in Bitbucket will no longer create a new run on the Cypress Dashboard. Fixes [#8720](https://github.com/cypress-io/cypress/issues/8720). - The forced garbage collection timer will no longer display when using a version of Firefox newer than 80. Fixes [#8725](https://github.com/cypress-io/cypress/issues/8725). - The browser dropdown is no longer covered when opened from the Runs tab in the Test Runner. Fixed in [#8745](https://github.com/cypress-io/cypress/issues/8745). - Fixed an issue where preprocessor-related plugins would cause tests not to run and a duplicate instance of Cypress to be spawned. Fixes [#8634](https://github.com/cypress-io/cypress/issues/8634). **Misc:** - Improved type definitions for [`cy.route2()`](https://on.cypress.io/route2). Addresses [#8694](https://github.com/cypress-io/cypress/issues/8694) and [#8782](https://github.com/cypress-io/cypress/issues/8782). - The Test Runner now shows an indicator in the footer and a toast notification if there is a new version available.
