did you open a ticket with support about it?
Exactly. MT has redefined what stable means. Perhaps we need another version: super-stable and tested. 
no i havent.
but most of the time a resealer doesnt help with the problems!
actually they can help,with settings etc. but not to fix a bug.
If you found a bug contact Mikrotik support.
Ain’t that the truth! In my early days with RouterOS, I had a problem where remote PPTP clients on the same subnet could not comminucate with the other LAN computers. A simple Proxy-ARP issue but the reseller here in South Africa (M) had no clue. I was even put through to their official Mikrotik trainer who gladly takes your money in return for ‘theory’ training. He didn’t have a clue of course!
Last week I phoned to enquire about the new 433UAH boards. “No problem” they say, “plenty of those”. “Cases?” say I. “Of course, plenty of 433 cases in stock” says the sales guy. I then hinted that “the new boards have onboard USB ports which surely need additional connectors on the case”. “Um, oh dear, yes you must be right, gee we didn’t think of that” was the mumbled reply.
I may as well just import the stuff myself…
Yet again - “stable, not stable” discussion…
It is at least 5th time someone starts this discussion.
Bottom line of previous discussions was:
“Rapid development of software have advantages and disadvantages, be aware of them and learn to live with them.”
MT is working like this for years, try to get some fix/feature request from Cisco 
- it can take up to year. Here everything happens fast, and more you talk/provide information to MT, the better they get. SO you get a feeling that you are part of development, par of community - sorry, but I like it the way it is
fair enough,best to stick with a version that all used functions are stable,until next one is released.
like the new menus setup, i can now see menus with my little eepc 401… 
it’s ‘stable’ in all tested cases. unfortunately, there’s no way to test all possible cases for all possible users
firefox installed, supposedly stable, but its crashes on my machine every few minutes. its the only thing that ever crashes on my PC. exactly as Chupaka said, it’s stable in their environment : )
Would all of this be put to rest if there was just a text warning on the download page that says ‘releases are considered stable after 2 weeks w/ no additional releases’.
By that standard all current RB hardware would be shipping with unstable firmware…

Which one do you suggest for RB450G?
the golden rule: if it works - do not upgrade it!
