Starting with package version `42-1`, the mkinitcpio systemd hook now includes `systemd-pcrosseparator.service` (as [intended by systemd v261]).
This affects the measurements of PCR values `0-7`, `9` and `12-14`. If you configured the systemd hook and unlock LUKS partitions, that depend on these values, you need to re-enroll the [TPM2] in use. For guidance, please refer to [systemd-cryptenroll(1)], or the [ArchWiki article on systemd-cryptenroll], when using pinned values. Refer to [systemd-pcrlock(8)], when relying on custom policies and a disabled `systemd-pcrlock-make-policy.service`.
