Doug Barton d1fdc8795a Update to the final release version of BIND 9.6.1. It has the following
changes from the 9.6.1rc1 version. The first 2 only affect DNSSEC.

          named could incorrectly delete NSEC3 records for
          empty nodes when processing a update request.

          Accept DS responses from delegation only zones.

          "delegation-only" was not being accepted in
          delegation-only type zones.

dnssec-signzone was designed so that it could sign a zone partially, using
only a subset of the DNSSEC keys needed to produce a fully-signed zone.
This permits a zone administrator, for example, to sign a zone with one
key on one machine, move the resulting partially-signed zone to a second
machine, and sign it again with a second key.
An unfortunate side-effect of this flexibility is that dnssec-signzone
does not check to make sure it's signing a zone with any valid keys at
all. An attempt to sign a zone without any keys will appear to succeed,
producing a "signed" zone with no signatures. There is no warning issued
when a zone is not signed.
This will be corrected in a future release. In the meantime, ISC
recommends examining the output of dnssec-signzone to confirm that
the zone is properly signed by all keys before using it.
