samba - Nov 2019 - Changes in Linux CIFS Kernel Module w.r.t. ACL features

I passed by the changelog for the Linux CIFS Kernel Module at
https://wiki.samba.org/index.php/LinuxCIFSKernel.
The following two sections caught my attention:
>> 4.19 Kernel (69 changesets, module version 2.13)
>>Allow cifs.ko to be built with insecure dialects disabled (vers=1.0 and
vers=2.0 not allowed). Add support for snapshot
>> mounts (specifying "snapshot=" on the mount allows a previous
version of the share to be mounted, read-only). Bug fixes
>> including improving statfs output; support for ACLs when using
vers=3.1.1; Allow displaying count of "slow" responses
>> (greater than 1 second). Add additional commonly requested tracepoints
(e.g. for reconnections, session expiration, slow
>> requests). Improve performance of statfs (add support for compounding
of query_fs calls).
My question: Which ACL support does it refer to?

>> 4.13 Kernel (24 changesets)
>> Default dialect changed to SMB3 (from CIFS). SMB3 support added for
"cifsacl" mount option (and can now emulate
>> retrieving mode from ACL in SMB3). Bug fixes. 
My question: This enables full support for mapping of CIFS/NTFS ACLs to/from
Linux file permission bits as with CIFS/SMBv1?
