It has some significant changes that I wanted to highlight from the changelog and quickly show the changes in the winbox interface.
!) bridge – implemented software based vlan-aware bridges;
!) switch – “master-port” conversion into a bridge with hardware offload “hw” option;
!) detnet – implemented “/interface detect-internet” feature;
The switch changes is the one that got my interest, as this is the one that I have known and used since I first started to use Mikrotik hardware. So now I have to get my head around the fact it has changed.
You can see from the images above that Master Port is no longer used and/or available under your interfaces to group interfaces together as switched ports. This is now done differently.
Upgraded one of my routers and I think I understand how this change impacts future configurations and setup process.
