Fedora Update Notification
FEDORA-2018-c894f896fd
2018-07-12 14:18:11.697524
——————————————————————————–

Name : knot-resolver
Product : Fedora 28
Version : 2.4.0
Release : 1.fc28
URL : https://www.knot-resolver.cz/
Summary : Caching full DNS Resolver
Description :
The Knot DNS Resolver is a caching full resolver implementation written in C
and LuaJIT, including both a resolver library and a daemon. Modular
architecture of the library keeps the core tiny and efficient, and provides
a state-machine like API for extensions.

The package is pre-configured as local caching resolver.
To start using it, start a single kresd instance:
$ systemctl start kresd@1.service

Knot Resolver 2.4.0 (2018-07-03) ================================ Incompatible
changes ——————– – minimal libknot version is now 2.6.7 to pull in
latest fixes (#366) Security ——– – fix a rare case of zones incorrectly
dowgraded to insecure status (!576) New features ———— – TLS session
