"Notes for BIND 9.16.39
Feature Changes

    libuv support for receiving multiple UDP messages in a single
    recvmmsg() system call has been tweaked several times between libuv
    versions 1.35.0 and 1.40.0; the current recommended libuv version is
    1.40.0 or higher. New rules are now in effect for running with a
    different version of libuv than the one used at compilation time. These
    rules may trigger a fatal error at startup:

        Building against or running with libuv versions 1.35.0 and 1.36.0
        is now a fatal error.

        Running with libuv version higher than 1.34.2 is now a fatal error
        when named is built against libuv version 1.34.2 or lower.

        Running with libuv version higher than 1.39.0 is now a fatal error
        when named is built against libuv version 1.37.0, 1.38.0, 1.38.1,
        or 1.39.0.

    This prevents the use of libuv versions that may trigger an assertion
    failure when receiving multiple UDP messages in a single system call.
    [GL #3840]

Bug Fixes

    named could crash with an assertion failure when adding a new zone into
    the configuration file for a name which was already configured as a
    member zone for a catalog zone. This has been fixed. [GL #3911]"

    When named starts up, it sends a query for the DNSSEC key for each
    configured trust anchor to determine whether the key has changed. In
    some unusual cases, the query might depend on a zone for which the
    server is itself authoritative, and would have failed if it were sent
    before the zone was fully loaded. This has now been fixed by delaying
    the key queries until all zones have finished loading. [GL #3673]"
