a/kernel-firmware-20230117_7e4f0ed-noarch-1.txz:  Upgraded.
a/kernel-generic-6.1.7-x86_64-1.txz:  Upgraded.
a/kernel-huge-6.1.7-x86_64-1.txz:  Upgraded.
a/kernel-modules-6.1.7-x86_64-1.txz:  Upgraded.
a/pkgtools-15.1-noarch-3.txz:  Rebuilt.
  installpkg: allow xz to use all the available CPU threads.
  makepkg: by default, allow xz to determine how many threads to use. However,
  on 32-bit platforms default to 2 threads since we were using this before. If
  allowed to decide, xz seems to only want to use a single thread on 32-bit.
ap/nano-7.2-x86_64-1.txz:  Upgraded.
ap/sudo-1.9.12p2-x86_64-1.txz:  Upgraded.
  This update fixes a flaw in sudo's -e option (aka sudoedit) that could allow
  a malicious user with sudoedit privileges to edit arbitrary files.
  For more information, see:
