Simple Alarm Clock disappeared from F-Droid repo


Simple Alarm Clock (com.better.alarm) just disappeared from main F-Droid repo (moved to F-Droid Archive repo). Latest version in the Archive repo is 2.9.01, but you can find that the actual latest version is 2.9.07 Now F-Droid Archive repo suggests me to uninstall the app due to some known vulnerabilities and some disabled algorithm (F-Droid 1.0-alpha4).
I’ve contacted the author of the app, but he doesn’t know anything about any vulnerabilities in his app.
Could you please clarify that moment with the vulnerabilities and the disabled algorithm?
Otherwise, please consider to return it back to the main repo.
Thank you.


The known vulnerabilities means it uses the old F-Droid signing key.
