Nope, strike lines 11-13, with no repos availabe it's not possible to upgrade from a previous release on i686.

I'd also add something like:

i686 packages will continue to be available in the x86_64 repos for multiarch (running 32bit binaries on 64 bit installs such as steam or wine or other legacy software)

Users with i686 installs may want to check if their hardware is 64bit capable and reinstall with a 64bit Fedora install, switch to another distribution that continues i686 support or move to new 64bit capable hardware.

I updated the wording.

Let's not tell people to switch to another distro in our release notes :)

Don't use the {PRODVER} attribute; these are useful in other versioned docs but not release note since we always start them from scratch and each particular relnote will only ever be applicable to a specific release.

Also, "no longer ships i686 repositories" - no article

Well, I think it shows we care about their situation and want them to be happy, but I'm fine dropping that if you think it's over the line.

FWIW, I'm okay with pointing users to some of our downstream choices or even remixes when they better cover specific use cases. Hopefully those distros will do the same for us!

Nit: "Fedora now no longer..." is clunky. I'd just go with "Fedora no longer...".
Or "As of this release, Fedora no longer..." if it's really important to tell people it's a new development.

Merged manually.
