It has been only a month since previous release, but I'm happy to announce UnrealIRCd 6.1.7(.1). The main focus of this release is adding new features, such as ASN support, more flexible ban user { } and require authentication { } blocks and more. See the Release Notes for all information.
UPDATE: A few days after 6.1.7 we released 6.1.7.1 which fixes a harmless message that appeared to IRCOps sometimes ("[BUG] trying to modify fd -2 in fd table"), depending on library versions and circumstances. If you already upgraded to 6.1.7 and you don't see this message or are not annoyed by it then there is no reason to upgrade from 6.1.7 to 6.1.7.1.
As always, you can download UnrealIRCd from unrealircd.org. If you want to upgrade on *NIX, then use: ./unrealircd upgrade
For those who missed: UnrealIRCd turned 25 years last May - See UnrealIRCd celebrates its 25th birthday.
