Gave beta 5 a test - install is monolithic - packages are gone.
Not possible to disable stuf fon routers that don't need those and conserve memory for useful things - e.g. wireless, ppp, ipv6, advanced tools to free up ram to run iBPG and/or MPLS
Why is RIP still there? BGP is gone on those small memory (32mb) routers, MPLS is also missing.
Also a feature request - combine ipv4 and ipv6 firewalls and perhaps combine the ip and ipv6 settings. Instead of living in different trees in cli and different menus in winbox combine them under one and where applicable add an option to specify which is which - if not specified apply to both.
