None
An --enable-querytrace configure switch is now available to enable very verbose query tracelogging. This option can only be set at compile time. This option has a negative performance impact and should be used only for debugging.
None
Large inline-signing changes should be less disruptive.
Signature generation is now done incrementally; the number
of signatures to be generated in each quantum is controlled
by "sig-signing-signatures number;".
[RT #37927]
Retrieving the local port range from net.ipv4.ip_local_port_range on Linux is now supported.
Asynchronous zone loads were not handled correctly when the zone load was already in progress; this could trigger a crash in zt.c. [RT #37573]
A race during shutdown or reconfiguration could cause an assertion failure in mem.c. [RT #38979]
Some answer formatting options didn't work correctly with dig +short. [RT #39291]
The BIND 9.9 (Extended Support Version) will be supported until June, 2017. https://www.isc.org/downloads/software-support-policy/
