- DNS over HTTPS support can be disabled at the compile time via the new
configuration option ``--disable-doh``. This allows BIND 9 to be
compiled without libnghttp2 library. [GL #2478]
compiled without libnghttp2 library. :gl:`#2478`
- Memory allocation has been substantially refactored, and is now based on
the memory allocation API provided by the `jemalloc` library on platforms
where it is available. This library is now recommended for building BIND 9.
:gl:`#2433`
- Previously, named accepted FORMERR responses both with and without
an OPT record, as an indication that a given server did not support
EDNS. To implement full compliance with RFC 6891, only FORMERR
responses without an OPT record are now accepted. This intentionally
breaks communication with servers that do not support EDNS and
that incorrectly echo back the query message with the RCODE field
set to FORMERR and the QR bit set to 1. :gl:`#2249`
