In addition to bug fixes and feature improvements, these releases also contain fixes for security vulnerabilities (CVE-2024-11187, CVE-2024-12705), about which more information is provided in the following Security Advisories:

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). As of this release, BIND will no longer build on RHEL7.
