Today I have released 6.1.7.2. It fixes an issue for people using Central Blocklist when the central blocklist server is down. Other than that, it removes support for local curlinstall since it is no longer needed. See also the release notes. That's all, there is nothing more, other than the version bump.
For almost everyone there is no reason to upgrade, it is mostly for new installations. Even people using Central Blocklist won't have to upgrade, as they were already informed privately a couple of days ago and provided a hot-patch, not requiring a restart.
UnrealIRCd 6.1.8, which will contain more changes, is scheduled for end of September / early October.
