_Released 1/31/2022_ **Features** - Enhancements were made to `.selectFile()` after receiving feedback after its initial release in [9.3.0](https://docs.cypress.io/guides/references/changelog#9-3-0). - The default behavior was updated to automatically infer the mime type of files based on their extension to correctly encode file uploads. Addressed in [#19751](https://github.com/cypress-io/cypress/issues/19751). - Added the `mimeType` property so you can explicitly set the mime type on files using the `mimeType` property. Addressed in [#19751](https://github.com/cypress-io/cypress/issues/19751). - Updated file contents types to allow either a [`TypedArray`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray) instance or a `Cypress.Buffer` instance, where previously file contents were expected to only be an instance of `Cypress.Buffer`. Addressed in [#19751](https://github.com/cypress-io/cypress/issues/19751). - Updated `.selectFile()` to retain the fileName of files read from disk to work with aliases. Addressed in [#19803](https://github.com/cypress-io/cypress/issues/19803). **Bugfixes:** - Fixed a regression in [9.3.0](https://docs.cypress.io/guides/references/changelog#9-3-0) to correctly parse the `--spec` CLI parameter for glob patterns containing a range. Fixes [#19783](https://github.com/cypress-io/cypress/issues/19783). - Fixed regression in [9.2.1](https://docs.cypress.io/guides/references/changelog#9-1-1) where the `--openssl-legacy-provider` flag was not being passed to the plugins' child process when the user's system Node version was Node 17+ built with OpenSSL v3+ which resulted in Cypress crashing when trying to run tests. Fixes [#19712](https://github.com/cypress-io/cypress/issues/19712). - Update `cy.type('{enter}')` to align with the W3C standards where a click event should be dispatched when the Enter key is pressed and the current focus is on astate-changing element with type `button`, `image`, `submit` or `reset`. Fixes [#19541](https://github.com/cypress-io/cypress/issues/19541).
