Security News > 2024 > July > BIND 9.20 released: Enhanced DNSSEC support, application infrastructure improvements

BIND 9.20, a stable branch suitable for production use, has been released.

In BIND 9.16, the developers introduced a new networking manager using libuv as an asynchronous event handler on top of the existing application infrastructure.

In BIND 9.20, the transition to libuv asynchronous loops is complete and BIND 9 is powered by libuv from the ground up.

A new database backend, called QP trie, has been added to BIND 9 and made the default cache and zone database, replacing the venerable RBTDB. The QP trie database uses the Userspace RCU Library, which is now mandatory to compile and run BIND 9.

The DNS name compression algorithm used in BIND 9 has been revised: it now compresses more thoroughly than before, so responses containing names with many labels may have a more compact encoding than before.

BIND 9 is open source and licensed under the MPL 2.0 license.
