a/kernel-firmware-20241101_376de1f-noarch-1.txz: Upgraded.
a/kernel-generic-6.11.6-x86_64-1.txz: Upgraded.
a/mkinitrd-1.4.11-x86_64-42.txz: Rebuilt.
geninitrd: you can still point this at a kernel symlink, but by default it
will make initrd-${KERNEL_VERSION}.img for the newest kernel it finds in
the /boot directory.
a/pkgtools-15.1-noarch-16.txz: Rebuilt.
make-kernel-backup: don't make copies of any of the files, nor include an
initrd in the package. The only added "files" will be two symlinks,
vmlinuz-backup, and initrd-backup.img (if symlinks are enabled).
d/kernel-headers-6.11.6-x86-1.txz: Upgraded.
d/valgrind-3.24.0-x86_64-1.txz: Upgraded.
k/kernel-source-6.11.6-noarch-1.txz: Upgraded.
l/fluidsynth-2.4.0-x86_64-1.txz: Upgraded.
l/gtk4-4.16.4-x86_64-1.txz: Upgraded.
l/libzip-1.11.2-x86_64-1.txz: Upgraded.
Fix performance regression in zip_stat introduced in 1.11.
l/spirv-llvm-translator-19.1.1-x86_64-1.txz: Upgraded.
n/uucp-1.07-x86_64-7.txz: Rebuilt.
Add some documentation. Thanks to jayjwa.
isolinux/initrd.img: Rebuilt.
kernels/*: Upgraded.
usb-and-pxe-installers/usbboot.img: Rebuilt.
