Our April 2025 maintenance releases of BIND 9 are available and can be downloaded from the ISC software download page, https://www.isc.org/download. Packages and container images provided by ISC will be updated later today.

A summary of significant changes in the new releases can be found in their release notes:

  - Current supported stable branches:

As a reminder, BIND’s supported platforms are listed in the ARM (https://downloads.isc.org/isc/bind9/9.18.33/doc/arm/html/chapter2.html#supported-platforms) and in this knowledgebase article (https://kb.isc.org/docs/supported-platforms). We ended support for RHEL 7 in June 2024 (as noted in release notes at the time). BIND will no longer build on RHEL7.
