As noted in our previous report, the most important feature of IPFire 2.19 Core Update 109 is the inclusion of the unbound 1.6.0 recursive and caching DNS resolver in the distro’s built-in DNS proxy to address some important bugs, re-activate QNAME minimisation and hardening below NX domains, and implement the ability for the firewall to check if a router loses longer DNS responses. Besides improving the DNS proxy, IPFire 2.19 Core Update 109 implements support for newer eMMC modules into the Linux kernel packages, adds support for standard 802.3 bridges to the built-in network scripts, improves support for various hardware architectures for the backup scripts, and lets the firewall GUI create subnets that are a subnet of one of the standard networks.
