Not to say previous releases haven't been as great (they all are), but I must say that 5.9 really does feel like a huge step towards a massive milestone (well done), and 6.0 will hopefully be the release that kills the GIANT lock for OpenBSD as a firewall. So really thank you..
For ourselves, the biggest anticlimax for OpenBSD 6.0 would be, still no 64bit support for the Queue size.. :( OpenBSD can shift traffic at well above 4.2Gbps now, so it's such a shame to be superficially limited to 4Gbps still :( And a small, but "nice to have" would be; Bandwidth defined as percentages of the parent queue. Just wishing, nothing else ;) Humbly yours, Andy.
