The instructions for installing BOINC 8.0 on Fedora were incorrect. Corrected instructions are here: https://boinc.berkeley.edu/linux_install.php
If you have a Fedora system, please retest.
For Android users, BOINC 8.0.0 is also available for testing on F-Droid: https://f-droid.org/en/packages/edu.berkeley.boinc/
Linux users! Please update your BOINC 8.0.0 (that contains backdoor in liblzma/xz library) to BOINC 8.0.1. TL;DR: You are still safe. More details here: https://aenbleidd.blogspot.com/2024/04/boinc-release-800-and-liblzma.html
