- Implement incremental resizing of RBT hash tables to perform the rehashing - Internal data structures maintained for each cache database are now
gradually instead all-at-once to be able to grow the memory usage gradually grown incrementally when they need to be expanded. This helps maintain
while keeping steady response rate during the rehashing. :gl:`#2941` a steady response rate on a loaded resolver while these internal data
structures are resized. :gl:`#2941`
- Add finer-grained ``update-policy`` rule types, ``krb5-subdomain-self-rhs`` - New finer-grained ``update-policy`` rule types,
and ``ms-subdomain-self-rhs``, that restrict updates to SRV and PTR records ``krb5-subdomain-self-rhs`` and ``ms-subdomain-self-rhs``, were added.

- Add support for OpenSSL 3.0.0. OpenSSL 3.0.0 deprecated 'engine' support. - OpenSSL 3.0.0 deprecated support for so-called "engines." Since BIND 9
If OpenSSL 3.0.0 has been built without support for deprecated functionality currently uses engine_pkcs11 for PKCS#11, compiling BIND 9 against an
pkcs11 via engine_pkcs11 is no longer available. At this point in time OpenSSL 3.0.0 build which does not retain support for deprecated APIs
there is no replacement ``provider`` for pkcs11 which is the replacement to makes it impossible to use PKCS#11 in BIND 9. A replacement for
the ``engine API``. :gl:`#2843` engine_pkcs11 which employs the new "provider" approach introduced in
OpenSSL 3.0.0 is in the making. :gl:`#2843`
