Release Notes for BIND Version 9.13.0

Introduction

   BIND 9.13 is an unstable development release of BIND. This document
   summarizes new features and functional changes that have been
   introduced on this branch. With each development release leading up to
   the stable BIND 9.14 release, this document will be updated with
   additional features added and bugs fixed.

Note on Version Numbering

   Prior to BIND 9.13, new feature development releases were tagged as
   "alpha" and "beta", leading up to the first stable release for a given
   development branch, which always ended in ".0".

   Now, however, BIND has adopted the "odd-unstable/even-stable" release
   numbering convention. There will be no "alpha" or "beta" releases in
   the 9.13 branch, only increasing version numbers. So, for example, what
   would previously have been called 9.13.0a1, 9.13.0a2, 9.13.0b1, and so
   on, will instead be called 9.13.0, 9.13.1, 9.13.2, etc.

   The first stable release from this development branch will be renamed
   as 9.14.0. Thereafter, maintenance releases will continue on the 9.14
   branch, while unstable feature development proceeds in 9.15.

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

     * BIND now can be compiled against the libidn2 library to add
       IDNA2008 support. Previously, BIND supported IDNA2003 using the
       (now obsolete and unsupported) idnkit-1 library.
     * named now supports the "root key sentinel" mechanism. This enables
       validating resolvers to indicate to which trust anchors are
       configured for the root, so that information about root key
       rollover status can be gathered. To disable this feature, add
       root-key-sentinel no; to named.conf.
     * The dnskey-sig-validity option allows the sig-validity-interval to
       be overriden for signatures covering DNSKEY RRsets. [GL #145]

Removed Features

     * dnssec-keygen can no longer generate HMAC keys for TSIG
       authentication. Use tsig-keygen to generate these keys. [RT #46404]
     * Support for OpenSSL 0.9.x has been removed. OpenSSL version 1.0.0
       or greater, or LibreSSL is now required.
     * The configure --enable-seccomp option, which formerly turned on
       system-call filtering on Linux, has been removed. [GL #93]
     * IPv4 addresses in forms other than dotted-quad are no longer
       accepted in master files. [GL #13] [GL #56]
     * IDNA2003 support via (bundled) idnkit-1.0 has been removed.
     * The "rbtdb64" database implementation (a parallel implementation of
       "rbt") has been removed. [GL #217]
     * The -r randomdev option to explicitly select random device has been
       removed from the ddns-confgen, rndc-confgen, nsupdate,
       dnssec-confgen, and dnssec-signzone commands.
       The -p option to use pseudo-random data has been removed from the
       dnssec-signzone command.

Feature Changes

     * BIND will now always use the best CSPRNG (cryptographically-secure
       pseudo-random number generator) available on the platform where it
       is compiled. It will use arc4random() family of functions on BSD
       operating systems, getrandom() on Linux and Solaris, CryptGenRandom
       on Windows, and the selected cryptography provider library (OpenSSL
       or PKCS#11) as the last resort. [GL #221]
     * BIND can no longer be built without DNSSEC support. A cryptography
       provder (i.e., OpenSSL or a hardware service module with PKCS#11
       support) must be available. [GL #244]
     * Zone types primary and secondary are now available as synonyms for
       master and slave, respectively, in named.conf.
     * named will now log a warning if the old root DNSSEC key is
       explicitly configured and has not been updated. [RT #43670]
     * dig +nssearch will now list name servers that have timed out, in
       addition to those that respond. [GL #64]
     * dig +noidnin can be used to disable IDN processing on the input
       domain name, when BIND is compiled with IDN support.
     * Up to 64 response-policy zones are now supported by default;
       previously the limit was 32. [GL #123]
     * Several configuration options for time periods can now use TTL
       value suffixes (for example, 2h or 1d) in addition to an integer
       number of seconds. These include fstrm-set-reopen-interval,
       interface-interval, max-cache-ttl, max-ncache-ttl, max-policy-ttl,
       and min-update-interval. [GL #203]

Bug Fixes

     * None.

End of Life

   BIND 9.13 is an unstable development branch. When its development is
   complete, it will be renamed to BIND 9.14, which will be a stable
   branch.

   The end of life date for BIND 9.14 has not yet been determined. For
   those needing long term support, the current Extended Support Version
   (ESV) is BIND 9.11, which will be supported until at least December
   2021. See https://www.isc.org/downloads/software-support-policy/ for
