+Notes for BIND 9.18.48
+----------------------
+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- Fix crash when reconfiguring zone update policy during active updates.
+
+  Fixed a crash that could occur when running rndc reconfig to change a
+  zone's update policy (e.g., from allow-update to update-policy) while
+  DNS UPDATE requests were being processed for that zone.
+
+  ISC would like to thank Vitaly Simonovich for bringing this issue to
+  our attention. :gl:`#5817`
+
+Bug Fixes
+~~~~~~~~~
+
+- Fix a crash triggered by rndc modzone on zone from configuration file.
+
+  Calling `rndc modzone` on a zone that was configured in the
+  configuration file caused a crash. This has been fixed.
+
+  ISC would like to thank Nathan Reilly for reporting this. :gl:`#5800`
+
+- Fix a crash triggered by rndc modzone on zone that already existed in
+  NZF file.
+
+  Calling `rndc modzone` didn't work properly for a zone hat was
+  configured in  the configuration file. It could crash if BIND 9 was
+  built without LMDB or if  there was already an NZF file for the zone.
+  In addition, `rndc modzone` failed in subsequent attempts. These
+  problems are now fixed. :gl:`#5826`
