Most likely new IPv6 features will not be added in ROS v6.
Thanks for being forthright about that. I do hope that ROSv7 reaches beta soon, in that case. I can't even remember all of the things that are promised to be fixed in v7, but it's a lot, and much of it in the IPv4 side of the house. Mikrotik is such a fantastic product in so many ways, I hate to see such a shocking gap in feature parity where IPv6 is concerned. I can use a Mikrotik to do damned-near anything I can imagine in IPv4 - their utility as a troubleshooting tool, workaround tool, execellent low-cost CPE, etc is mind boggling. In IPv6, though, all of that goes right out the window.
My company is a complete Mikrotik shop for CPE except stuff that Mikrotik doesn't do, such as VoIP ATAs / DSL modems. I'm getting ready to focus on rolling out production IPv6 to the customer base. We've had the protocol operational for years on our core, but never have started delivering it as part of the daily production. We're actually fortunate enough to have enough IPv4 address space left to continue operations in a native dual stack model if need be, but many users on here aren't so lucky, and without any advanced functionality in IPv6, Mikrotik really loses its edge as "the lowest cost MPLS-capable router anywhere."
This saddens me, but I keep hoping that things will improve on this front.
