| 12 | +Notes for BIND 9.19.13 |
| 13 | +---------------------- |
| 14 | + |
| 15 | +New Features |
| 16 | +~~~~~~~~~~~~ |
| 17 | + |
| 18 | +- :iscman:`dnstap-read` can now print long timestamps with millisecond |
| 19 | + precision. :gl:`#2360` |
| 20 | + |
| 21 | +Bug Fixes |
| 22 | +~~~~~~~~~ |
| 23 | + |
| 24 | +- When the same :any:`notify-source` address and port number was |
| 25 | + configured for multiple destinations and zones, an unresponsive server |
| 26 | + could tie up the relevant network socket until it timed out; in the |
| 27 | + meantime, NOTIFY messages for other servers silently failed. |
| 28 | + :iscman:`named` will now retry sending such NOTIFY messages over TCP. |
| 29 | + Furthermore, NOTIFY failures are now logged at the INFO level. |
| 30 | + :gl:`#4001` :gl:`#4002` |
| 31 | + |
| 32 | +- The :any:`max-transfer-time-in` and :any:`max-transfer-idle-in` have |
| 33 | + not had any effect since the BIND 9 networking stack was refactored in |
| 34 | + version 9.16. The missing functionality has been re-implemented and |
| 35 | + incoming zone transfers now time out properly when not progressing. |
| 36 | + :gl:`#4004` |
| 37 | + |
| 38 | +- The read timeout in :iscman:`rndc` is now 60 seconds, matching the |
| 39 | + behavior in BIND 9.16 and earlier. It had previously been lowered to |
| 40 | + 30 seconds by mistake. :gl:`#4046` |
| 41 | + |
| 42 | +- When the ``ISC_R_INVALIDPROTO`` (``ENOPROTOOPT``, ``EPROTONOSUPPORT``) |
| 43 | + error code is returned by libuv, it is now treated as a network |
| 44 | + failure: the server for which that error code is returned gets marked |
| 45 | + as broken and is not contacted again during a given resolution |
| 46 | + process. :gl:`#4005` |
| 47 | + |
| 48 | +- When removing delegations from an opt-out range, empty-non-terminal |
| 49 | + NSEC3 records generated by those delegations were not cleaned up. This |
| 50 | + has been fixed. :gl:`#4027` |
| 51 | + |
| 52 | +- A flaw in reworked code responsible for accepting TCP connections has |
| 53 | + been addressed. This issue could cause a visible performance drop for |
| 54 | + TCP queries on some platforms, notably FreeBSD, and has now been |
| 55 | + fixed. :gl:`#3985` |
| 56 | + |
| 57 | +- Log file rotation code did not clean up older versions of log files |
| 58 | + when the logging :any:`channel` had an absolute path configured as a |
| 59 | + ``file`` destination. This has been fixed. :gl:`#3991` |
| 60 | + |
| 61 | +Known Issues |
| 62 | +~~~~~~~~~~~~ |
| 63 | + |
| 64 | +- There are no new known issues with this release. See :ref:`above |
| 65 | + <relnotes_known_issues>` for a list of all known issues affecting this |
| 66 | + BIND 9 branch. |
