RouterOS 6.41 released in Dec has a new bridge implementation. One of the consequence of that is that there are no more master/slave ethernet configs. When upgrading to 6.41, sometimes the conversion gets screwed up leaving you with a non-working bridge. So for those who upgrading now, you might want to go straight to 6.42rc5.
3/1/2018 Version 6.42rc5 has been released.
CODE
Changes since previous release:
*) bridge - fixed bridge related settings conversation during upgrade from pre-v6.41 bridge implementation (introduced v6.41);

*) detnet - additional work on "detect-internet" implementation;

*) ike1 - display error message when peer requests "mode-config" when it is not configured;
*) ike1 - fixed "aes-ctr" and "aes-gcm" encryption algorithms (introduced v6.41);
*) ike2 - improve half-open connection handling;

*) log - properly report bridge interface MAC address changes;
*) poe-out - do not show "poe-out-current" on devices which can not determine it;
*) rb1100ahx4 - fixed reset button responsiveness when regular firmware is used;
*) ssh - improved key import error messages;

Thanks for the heads up. Updated!
Got apa interesting tweaks?

Haven't really played with it much but I really like the new bridge implementation especially when working with vlans. It's much more intuitive, to me anyway.
