Cypress v3.8.0 — Release Notes & Engineering Impact

*Released 12/12/2019* **Features:** - Chrome can now be run in headless mode by using `cypress run --headless --browser chrome`. Addresses [#832](https://github.com/cypress-io/cypress/issues/832). - Cypress now accepts a [`--tag`](https://on.cypress.io/command-line#cypress-run-tag-lt-tag-gt) argument to be used to identify separate runs. Any tags assigned will be shown on the run in the Cypress Dashboard. Addresses [#2561](https://github.com/cypress-io/cypress/issues/2561). - The commands [`.its()`](https://on.cypress.io/its) and [`.invoke()`](https://on.cypress.io/invoke) now accept an `options` object to allow changing logging options. Addresses [#1450](https://github.com/cypress-io/cypress/issues/1450). - Cypress will now attempt to use the `unzip` binary during `cypress install` before trying the slower, Node.js-based unzipping method. Addresses [#3803](https://github.com/cypress-io/cypress/issues/3803). - Upgraded Electron to 7.1.4. This bumps the internal Node version to 12.8.1 and the internal Chromium version to 78.0.3904.113. **Bugfixes:** - We fixed a regression in [3.5.0](https://on.cypress.io/changelog-3-5-0) where Cypress would crash on Windows when trying to pass a url through `--config` or `--env` command line flags. Fixes [#5466](https://github.com/cypress-io/cypress/issues/5466). - We fixed a regression in [3.5.0](https://on.cypress.io/changelog-3-5-0) where a supplied `Cookie` header during "`cy.visit()` visit or [`cy.request()`](https://on.cypress.io/request) would be overwritten by the `Cookie` header generated from the browser's cookie store. Fixes [#5894](https://github.com/cypress-io/cypress/issues/5894). - We fixed a regression in [3.5.0](https://on.cypress.io/changelog-3-5-0) where [`cy.getCookie()`](https://on.cypress.io/getcookie) would incorrectly filter cookies by their domain, leading to unexpected results. Fixes [#5656](https://github.com/cypress-io/cypress/issues/5656). - We fixed a regression in [3.5.0](https://on.cypress.io/changelog-3-5-0) where calling `.type({ force: true })` on hidden inputs would not type the correct characters. Fixes [#5835](https://github.com/cypress-io/cypress/issues/5835). - We fixed a regression in [3.5.0](https://on.cypress.io/changelog-3-5-0) where [`.type()`](https://on.cypress.io/type) was not respecting previous selections if the current value of the input was the same as the key. This also fixed an where [`.type()`](https://on.cypress.io/type) would not respect previous selections in non-selectionRange inputs (like email or number inputs). Fixes [#5703](https://github.com/cypress-io/cypress/issues/5703). - During visibility checks, Cypress now properly evaluates a DOM element transformed by `scale(0)` or `rotateY(90deg)` as not visible. Fixes [#723](https://github.com/cypress-io/cypress/issues/723). - Fixed a bug where the specs list in interactive mode would not refresh when files are changed on disk. Fixes [#5933](https://github.com/cypress-io/cypress/issues/5933). - `env` configuration option displays properly within the settings panel. Previously, setting env options would incorrectly render `"undefined"` as the value. Fixes [#5859](https://github.com/cypress-io/cypress/issues/5859). **Misc:** - We removed the max viewport size and lowered min viewport size to `0` for [`cy.viewport()`](https://on.cypress.io/viewport) Addresses [#5871](https://github.com/cypress-io/cypress/issues/5871) and [#5892](https://github.com/cypress-io/cypress/issues/5892). - The Test Runner now shows a non-Chrome logo for [browsers passed in via `config.browser`](https://on.cypress.io/launching-browsers#Customize-available-browsers) that are not of the Chrome family. It also supports showing the Firefox logo (in preparation for Firefox browser support). Fixes [#5745](https://github.com/cypress-io/cypress/issues/5745). - We updated the look of some of our icons. Addressed in [#5822](https://github.com/cypress-io/cypress/pull/5822). - We're continuing to make progress in converting our codebase from CoffeeScript to JavaScript. Addresses [#2690](https://github.com/cypress-io/cypress/issues/2690) in [#5643](https://github.com/cypress-io/cypress/pull/5643). - `cy.request` will now automatically encode special characters in the request URL, including Unicode.
