3.0 is out, 3.1 is out, so…when will 2.9 vanish from download section? 
This will be best imaginable signal, that MT3 is ready for production use - or so does MikroTik hope
I think that 2.9 will be there for some time, because not all of users want to switch to 3.x
Well, that’s the perplexing state of things… We apparently have 2 stable branches now…
2.9 is considered legacy
yes, until now we used .v..49, and we have nice to sleep...
so, sorry we are never try beta.... 
maybe later...., we don't know why...!

Version 3 is not beta ! It is released as stable version.
Everyone is welcome to report issues with 3.0 versions (if there are any).
Posts with arguments are more worth for other users too.
Running 50+ 3.0 radios here without any issues. There is a learning curve and some things to do differently.
Unfortunately many users/operators her have a hard time grasping the concept of doing things differently and can’t get ver 3 to run…
