• Deprecation of extended and extended/deploy editions. See #14728. In the "Repository packages" and "Package managers" sections for each OS, replace the extended edition instructions with the standard edition instructions. Don't display both commands and don't display a deprecation badge. Including two commands for every installation method will be difficult to read and potentially overwhelming. In the "Editions" sections, display deprecation badges. In the "Build from source" sections, display deprecation badges and retain instructions for building the extended and extended/deploy editions.

• Never auto-fallback to page resources in other roles/versions. See #14753. I don't know enough about this to determine if we need adjust the documentation.
• Add a more flexible filename identifier scheme that also allows setting roles and versions. See #14754.
