The missing functionality has been 21 re-implemented and incoming zone transfers now time out properly when 22 not progressing. :gl:`#4004` 23 24- The read timeout in :iscman:`rndc` is now 60 seconds, matching the 25 behavior in BIND 9.16 and earlier. It had previously been lowered to 26 30 seconds by mistake. :gl:`#4046` 27 28- When the ``ISC_R_INVALIDPROTO`` (``ENOPROTOOPT``, ``EPROTONOSUPPORT``) 29 error code is returned by libuv, it is now treated as a network 30 failure: the server for which that error code is returned gets marked 31 as broken and is not contacted again during a given resolution 32 process. :gl:`#4005` 33 34- When removing delegations from an opt-out range, empty-non-terminal 35 NSEC3 records generated by those delegations were not cleaned up. This 36 has been fixed. :gl:`#4027` 37 38- Log file rotation code did not clean up older versions of log files 39 when the logging :any:`channel` had an absolute path configured as a 40 ``file`` destination. This has been fixed. :gl:`#3991` 41 42Known Issues 43~~~~~~~~~~~~ 44 45- Sending NOTIFY messages silently fails when the source port specified 46 in the :any:`notify-source` statement is already in use. This can 47 happen e.g. when multiple servers are configured as NOTIFY targets for 48 a zone and some of them are unresponsive. This issue can be worked 49 around by not specifying the source port for NOTIFY messages in the 50 :any:`notify-source` statement; note that source port configuration is 51 already `deprecated`_ and will be removed altogether in a future 52 release. :gl:`#4002` 53 54- See :ref:`above <relnotes_known_issues>` for a list of all known 55 issues affecting this BIND 9 branch. 56 57.. _deprecated: https://gitlab.isc.org/isc-projects/bind9/-/issues/3781 58
