Feature Changes
~~~~~~~~~~~~~~~
-- Add DEBUG(1) level messages when starting and ending BIND 9 task exclusive mode
- that stops the normal DNS operation (f.e. for reconfiguration, interface
- scans, and other events that require exclusive access to a shared resources).
- :gl:`#3137`
+- DEBUG(1)-level messages were added when starting and ending the BIND 9
+ task-exclusive mode that stops normal DNS operation (e.g. for
+ reconfiguration, interface scans, and other events that require
+ exclusive access to a shared resource). :gl:`#3137`
Bug Fixes
~~~~~~~~~
-- TCP connections could hang indefinitely if the TCP write buffers
- were full because of the other party not reading sent data. This has
- been fixed by adding a "write" timer. Connections that are hung
- while writing will now time out after the ``tcp-idle-timeout`` period
- has elapsed. :gl:`#3132`
-
-- The ``max-transfer-time-out`` and ``max-transfer-idle-out`` options were
- not implemented when the BIND 9 networking stack was refactored in 9.16.
- The missing functionality has been re-implemented and outgoing zone
- transfers now time out properly when not progressing. :gl:`#1897`
