Cypress v4.3.0. Source highlight: *Released 3/30/2020*

## New Features
- Errors shown in the Test Runner have a new design including an expandable stack trace, better highlighting of code elements, and 'Learn more' links that link to relevant Cypress documentation. This is part of our larger improvements to error display with more exciting features to come. Addresses #3762.
- When you open a Cypress project, clicking on the **Settings** tab and clicking into the **Experiments** panel will display the experimental features that are available and whether they are enabled for your project.
- Added support for setting cookie `sameSite` values via `cy.setCookie()`. Addresses #2437.
- Added experimental support for adding `sameSite` values to the objects yielded from `cy.setCookie()`, `cy.getCookie()`, and `cy.getCookies()`. Users can enable this by setting the `experimentalGetCookiesSameSite` configuration value to `true`. In Cypress 5, this will be the default. Addresses #2437.
- Added support for the `SameSite` cookie attribute in `cy.request()`, `cy.visit()`, and proxied HTTP requests. Addresses #6757.
- Type added for `tag` property when using Module API. Addresses #6795.
