Permission on /var/tmp changes after upgrade to Solaris 11.4

Hi team, I hope this question is in the right category.

So after upgrading from 11.3 to 11.4 I found out the permissions changed from 1777 in 11.3 to 0755 in 11.4

:~$ ls -ld /var/tmp

drwxr-xr-x  2 root   root      2 Oct 16 11:42 /var/tmp

The consequence of this is bring impact to the application on the organization I work. So I guess I would need to restore the permissions if we need it.

Thanks in advance.
