I think the commit message of the relevant commit describes the situation quite well: https://git.proxmox.com/?p=pve-common.git;a=commit;h=354ec8dee37d481ebae49b488349a8e932dce736 it disables learning on the individual ports - but at the same time also the unicast_flood flag is set to false - see `man 8 bridge` - so I'd expect the combination of the 2 to work as advertised (and will try to rephrase the release note entry a bit too be less confusing) I hope this helps!
