The ps command in #OracleSolaris 11.4.69 now accepts the -I flag to display the start time ("STIME") column in an ISO 8601 format. Alternatively, the sitime keyword can be passed to the -o option to specify a start time in an ISO 8601 format.
In #OracleSolaris 11.4.69, the default/etc/ssh/sshd_config file has added "Include /etc/ssh/sshd_config.d/*.conf" so you can just drop new config fragments in that directory via IPS/ansible/puppet/etc. instead of having to edit the existing configs. The equivalent was also done for the ssh_config file, if you need to do things like enable old algorithms to ssh to hosts running older ssh versions.
The autofs SMF service in #OracleSolaris 11.4.69 has added support for reloading automount maps on a periodic basis, so when you update the map on your LDAP server you don't need to manually run automount on all the clients to get the new maps. You can also run "svcadm refresh" now to force a manual reload.
