You still forgot my #[SUP-126246]: Winbox IPv6 ND reachable time units. Cosmetic bug (works correctly and the value is specified in seconds, only Winbox and Webfig show wrong units label “ms” instead of “s”), but introduced in 6.47.10 which itself was a long-term release.
Reported exactly one year ago, and the response was: “This has been fixed in RouterOS V7, in RouterOS V6 branches this won’t be fixed as V6 updates will only include security fixes.” (yeah, so the long-term 6.47.10 showing the wrong units was a security fix?)
I plan to stick with v6 for a long time on RB931/RB941-2nD (the cheap basic routers which I give to customers for free with the service, tired of supporting cheap crappy chinese routers), simply because of limited hardware resources.
