* Most configuration options that previously accepted percentage values
now also accept permille values with the '‰' suffix (instead of '%').
- * systemd-logind will offer hibernation only if the currently used
- kernel image is still available on disk.
-
* systemd-resolved may now optionally use OpenSSL instead of GnuTLS for
DNS-over-TLS.
