First Router Designed Specifically For OpenWrt Released

This is a most excellent place for technology news and articles.
I personally just buy MikroTik routers. Yeah, they're not FOSS AFAIK, but they work really well and there are a ton of guides and whatnot. They also have a good assortment of hardware, so finding the right fit for my network is pretty easy.
If I ever decided to go away from MikroTik, I'd probably DIY my own router instead of going w/ something like OpenWRT. I did my time w/ DD-WRT, Tomato, and OpenWRT, and honestly, I prefer my MikroTik router.
I once setup MikroTik routers... they were cool, but the ipv6 implementation required manual intervention - this is not something you want with an isp that dynamically rotates their ipv6 addresses often. Once I discovered pfSense/OPNSense, it was so much better in configurability and ease of upgrade, as those OSses are FreeBSD-based and designed to run on PCs.
My ISP doesn't support IPv6, so I haven't needed to touch that, but we'll be getting muni fiber soon-ish (they claim the next year or two), so that could change. I'll definitely think about upgrading to pfSense or something when that happens.
