OpenWrt "Chaos Calmer" 15.05 released

I define "old" as "not manufactured any longer"

the WNDR3700 was at v4 the last time I looked (a couple years ago), so talking about the v2 even at that time was old. There were a couple years there where none of the wndr3700 devices that were being manufactured were usable with OpenWRT because of the change in flash. That has been fixed in the last year or so (I don't know if it made it in to BB, but it was in the available source for compiling your own image, and is in CC)

If a device cannot be purchased new from the manufacturer, I call it "old"

"Old" devices can still be used, and I'm about to buy 60 "old" devices to support an upcoming conference. But I would not point at them as the first choice, but only as a last chance.

Like dlang wrote, the issue is getting hold of one of those stable and nicely working devices. When I tried to get a 3700v2, I was sent a later version (I think it was a v4) at the first try, even though it was described as v2 when ordering. Thankfully, I got a 3800 in the end, and at a reasonable price. They used to appear on Amazon from time to time but only in low quantities.

So yeah, if you already have one of those, they're super-awesome. But when it's basically impossible to buy them, recommending them to potential buyers is not that useful.
