Rebased on the GCC (GNU Compiler Collection) 9.2 compiler system series, IPFire 2.25 Core Update 141 is here to introduce a brand new DNS (Domain Name Server) system that features a unified settings page, the ability to add more than two DNS servers, DNS-over-TLS support, Safe Search support, faster boot, and other optimizations. IPFire will now automatically use the fastest DNS server when more are added. Moreover, system administration can now easily filter adult content from the entire network without the need of a web proxy. It is now also possible to use TLS and TCP as transport on networks where the ISP filters DNS responses.
