+BIND 9.20.19
+------------
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Update requirements for system test suite. ``a2a9b1b878``
+
+  Python 3.10 or newer is now required for running the system test
+  suite. The required python packages and their version requirements are
+  now tracked in `bin/tests/system/requirements.txt`.
+
+  Support for pytest 9.0.0 has been added its minimum supported version
+  has been raised to 7.0.0. The minimum supported dnspython version has
+  been raised to 2.3.0. :gl:`#5690`  :gl:`#5614` :gl:`!11469`
+
+- Use enum rather than numbers for isc_base64_tobuffer and
+  isc_hex_tobuffer. ``47b8ca5ac7``
+
+  Use isc_one_or_more and isc_zero_or_more rather than (-2) and (-1)
+  when calling isc_base64_tobuffer. Similarly for isc_hex_tobuffer. This
+  should help reduce the probability that the wrong number is used and
+  it makes the intent clearer. :gl:`#5713` :gl:`!11498`
+
+Bug Fixes
+~~~~~~~~~
+
+- Fix inbound IXFR performance regression. ``318a7535d2``
+
+  Very large inbound IXFR transfers were much slower compared to BIND
+  9.18. The performance was improved by adding specialized logic to
+  handle IXFR transfers. :gl:`#5442` :gl:`!11355`
+
+- Make catalog zone names and member zones' entry names
+  case-insensitive. ``cd23f0250a``
+
+  Previously, the catalog zone names and their member zones' entry names
+  were unintentionally case-sensitive. This has been fixed. :gl:`#5693`
+  :gl:`!11450`
+
+- Use const pointer with strchr of const pointer. ``736b84ad46``
+
+  :gl:`#5694` :gl:`!11463`
+
+- Fix brid and hhit implementation. ``f73ef3b24f``
+
+  Fix bugs in BRID and HHIT implementation and enable the unit tests.
+  :gl:`#5710` :gl:`!11492`
+
+- DSYNC record incorrectly used two octets for the Scheme Field.
+  ``bd9f73c705``
+
+  When creating the `DSYNC` record from a structure, `uint16_tobuffer`
+  was used instead of `uint8_tobuffer` when adding the scheme, causing a
+  `DSYNC` record that was one octet too long. This has been fixed.
+  :gl:`#5711` :gl:`!11483`
+
+- Fix a possible issue with reponse policy zones and catalog zones.
+  ``3d0823ee68``
+
+  If a response policy zone (RPZ) or a catalog zone contained an
+  `$INCLUDE` directive, then manually reloading that zone could fail to
+  process the changes in the response policy or in the catalog,
+  respectively. This has been fixed. :gl:`#5714` :gl:`!11496`
+
