This document summarizes changes since the last production release of BIND on the corresponding major release branch.
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.
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]
When retrying a query via TCP due to the first answer being truncated, dig will now correctly send the SIT (server identity token) value returned by the server in the prior response. [RT #39047]
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]
A bug in the RPZ implementation could cause some policy zones that did not specifically require recursion to be treated as if they did; consequently, setting qname-wait-recurse no; was sometimes ineffective. This has been corrected. In most configurations, behavioral changes due to this fix will not be noticeable. [RT #39229]
A bug in RPZ could cause the server to crash if policy zones were updated (e.g. via rndc reload or an incoming zone transfer) while RPZ processing was still ongoing for an active query. [RT #39415]
The end of life for BIND 9.10 is yet to be determined but will not be before BIND 9.12.0 has been released for 6 months. https://www.isc.org/downloads/software-support-policy/
