I've updated as many applications as possible to a supported runtime version. (See: https://discourse.flathub.org/t/eol-runtime-working-team/6627/24)

My knowledge is limited, and I haven't been able to update the following applications.

I would be grateful for your help.

End-of-life runtime transition

To focus our resources on maintaining high-quality, up-to-date runtimes, we'll be completing the removal of several end-of-life runtimes in January 2026.

Apps using runtimes older than freedesktop-sdk 22.08, GNOME 45, KDE 5.15-22.08 or KDE 6.6 will be marked as EOL shortly.
