MediaElement has been upgraded to 4.2.6 (see #39686), which includes many bug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. fixes as well as:
- Removal of all dependencies to jQuery in code to make it more portable
- Updated UI User interface, using flexbox
- Improved accessibility Accessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers).

- Dropped support for older browsers (supports IE11+, Chrome, FF, Safari, Android 4+ and iOS The operating system used on iPhones and iPads. 8+), keep in mind that ME.js applies to the front end and not just WP Admin (and super admin)

- Added support for iOS 10 and Mac OS on websites using HTTPS HTTPS is an acronym for Hyper Text Transfer Protocol Secure. HTTPS is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between your browser and the website are encrypted. This is especially helpful for protecting sensitive data like banking information.

Props to @rafa8626 for helping write this Dev Note Each important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase..
