Introduction This document summarizes changes since the last production release of BIND on the corresponding major release branch. Download The latest versions of BIND 9 software can always be found at http://www.isc.org/downloads/. There you will find additional information about each release, source code, and pre-compiled versions for Microsoft Windows operating systems. Security Fixes None New Features 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. Feature Changes 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. Bug Fixes 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] End of Life The BIND 9.9 (Extended Support Version) will be supported until June, 2017. https://www.isc.org/downloads/software-support-policy/ Thank You Thank you to everyone who assisted us in making this release possible.
