[Samba] File Create Mask - did something change since the update?

Hi all,

After updating Samba last Friday (from 4.3.3-1 to 4.4.5-1), some issues
appeared that weren't there before.

Consider the following share (on a domain member):

path = /srv/samba/sharename
guest ok = no
writeable = yes
acl_xattr:ignore system acls = yes

This worked perfectly well until now and Windows ACLs were correctly
applied. Since last Friday, however, new files are created with the
following Linux permissions:

-rwx r-- ---

i.e., only the owner can modify the new files.

Windows share permissions and ACLs on the other hand look perfectly fine
but they are still restricted by the ("invisible") Linux permissions which
made this error kind of difficult to find.

What changed that this share definition is not working anymore, and how do
you propose I change it to get rid of the issue?

Appreciate any pointers.
