BIND 9.5.0a7 is a alpha release for BIND 9.5.0.
This is a technology preview of new functionality to be be
released in BIND 9.5.0. New APIs are not yet frozen.
Please as a minimum perform a test build on your operating
system. We don't have test platforms for every operating
system and sometimes we accidently break builds. Now is
the time to tell us about that. bind9-bugsisc.org.
Bugs should be reported to bind9-bugsisc.org.
BIND 9.5 has a number of new features over BIND 9.4, including:
BIND 9.5.0 has a number of new features over 9.4,
