Introducing BIND 9.9.0a3
This is a technology preview of new functionality to be be
included in BIND 9.9.0. Not all new functionality is in
place. APIs and configuration syntax are not yet frozen.
BIND 9.9.0a3 is the third alpha release of BIND 9.9.0. It
differs from 9.9.0a2 largely in that it fixes several bugs.
However, there are a few new bits of functionality:
RPZ update:
- fix precedence among competing rules
- improve ARM text including documenting rule
precedence
- try to rewrite CNAME chains until first hit
- new "rpz" logging channel
Enable DLZ modules to retrieve client information, so that
responses can be changed depending on the source address of
the query.
Reduce the time spent in "rndc reconfig" by parsing the
config file before pausing the server.

release or visit https://deepthought.isc.org/article/AA-00477/81/
