4708. [cleanup] Legacy Windows builds (i.e. for XP and earlier)
are no longer supported. [RT #45186]
4707. [func] The lightweight resolver daemon and library (lwresd
and liblwres) have been removed. [RT #45186]
4706. [func] Code implementing name server query processing has
been moved from bin/named to a new library "libns".
Functions remaining in bin/named are now prefixed
with "named_" rather than "ns_". This will make it
easier to write unit tests for name server code, or
link name server functionality into new tools.
[RT #45186]
digest length were used incorrectly, leading to
interoperability problems with other DNS
implementations. This has been corrected.
(Note: If an oversize key is in use, and
compatibility is needed with an older release of
BIND, the new tool "isc-hmac-fixup" can convert
the key secret to a form that will work with all
versions.) [RT #20751]
