What's new in 6.41rc21 (2017-Sep-01 08:56):
Important note!!! Backup before upgrade!
RouterOS (v6.40rc36-rc40 and) v6.41rc1+ contains new bridge implementation that supports hardware offloading (hw-offload).
This update will convert all interface "master-port" configuration into new bridge configuration, and eliminate "master-port" option as such.
Bridge will handle all Layer2 forwarding and the use of switch-chip (hw-offload) will be automatically turned on based on appropriate conditions.
The rest of RouterOS Switch specific configuration remains untouched in usual menus for now.
Please, note that downgrading to previous RouterOS versions will not restore "master-port" configuration, so use backups to restore configuration on downgrade.
Before an upgrade:
1) Remember to make backup/export files before an upgrade and save them on another storage device;
2) Make sure the device will not lose power during upgrade process;
3) Device has enough free storage space for all RouterOS packages to be downloaded.
