re: [Bob McBobbington]
Hello Bob,
Test days usually run for several days, not just one.
You can test and report results anytime during that window or later after test days is also fine. The ones with confirmed dates are listed at testdays.fedoraproject.org.
Many of the others are still being planned and only exist as Forge tickets for now and dates will be set later. There’s no hard deadline for reporting, any bugs you find go to Bugzilla as usual.
added comment about plasma 6.8 during f45: Making sure you're not a bot!
The systemd-boot vs GRUB question is an upstream/Fedora engineering topic.
systemd-boot is NOT the default and not officially supported as a bootloader in Fedora. If you want to raise it, fedora-devel mailing list (devel@lists.fedoraproject.org) or Fedora Discussion (discussion.fedoraproject.org) would be the right place.
