[ANN] nsdiff version 1.33

[Tony Finch]

nsdiff is an add-on tool for BIND that compares old and new versions of a
zone and generates an nsupdate script that turns the old version into the
new version. It is designed to bridge the gap between static master files
and dynamic DNS updates, making it easier to use "auto-dnssec maintain".

This update includes an important fix to deal with replacing a CNAME with
other RRtypes or vice versa. The DNS update protocol requires that all the
old RRs are removed before adding the new RRs if any of them are CNAMEs.
If you violate this requirement part of the update will be ignored, with
the only sign of a problem being a message in BIND's logs.

Other changes include: configurable SOA serial number formats and
verbosity; more control over how large numbers of changes are split into
multiple update requests; and fewer restrictions on DNS record owner name
syntax.
