"Notes for BIND 9.16.26
Feature Changes

    The DLZ API has been updated: EDNS Client-Subnet (ECS) options sent
    by a client are now included in the client information sent to DLZ
    modules when processing queries. [GL #3082]

Bug Fixes

    Previously, recvmmsg support was enabled in libuv 1.35.0 and 1.36.0,
    but not in libuv versions 1.37.0 or greater, reducing the maximum
    query-response performance. This has been fixed. [GL #3095]

    A failed view configuration during a named reconfiguration procedure
    could cause inconsistencies in BIND internal structures, causing
    a crash or other unexpected errors. This has been fixed. [GL #3060]

    Previously, named logged a “quota reached” message when it hit its
    hard quota on the number of connections. That message was
    accidentally removed but has now been restored. [GL #3125]

    Build errors were introduced in some DLZ modules due to an
    incomplete change in the previous release. This has been fixed. [GL
    #3111]"
