This is almost surely related to this upstream change:

,----
| CHANGES WITH 198:
| 
|         * The journal files are now owned by a new group
|           "systemd-journal", which exists specifically to allow access
|           to the journal, and nothing else. Previously, we used the
|           "adm" group for that, which however possibly covers more
|           than just journal/log file access. This new group is now
|           already used by systemd-journal-gatewayd to ensure this
|           daemon gets access to the journal files and as little else
|           as possible. Note that "make install" will also set FS ACLs
|           up for /var/log/journal to give "adm" and "wheel" read
|           access to it, in addition to "systemd-journal" which owns
|           the journal files. We recommend that packaging scripts also
|           add read access to "adm" + "wheel" to /var/log/journal, and
|           all existing/future journal files. To normal users and
|           administrators little changes, however packagers need to
|           ensure to create the "systemd-journal" system group at
|           package installation time.

As a result, journalctl doesn't work:

,----
| $ journalctl                           
| Hint: You are currently not seeing messages from other users and the system.
|       Users in the 'systemd-journal' group can see all messages. Pass -q to
|       turn off this notice.
| No journal files were opened due to insufficient permissions.
