 - Support for Offline KSK implemented.

-  management. Signed Key Response (SKR) files created with `dnssec-ksr`
-  (or other program) can now be imported into `named` with the new `rndc
-  skr -import` command. Rather than creating new DNSKEY, CDS and CDNSKEY
-  records and generating signatures covering these types, these records
-  are loaded from the currently active bundle from the imported SKR.

-- Support restricted key tag range when generating new keys.
+- Support a restricted key tag range when generating new keys.
+
+  When multiple signers are being used to sign a zone, it is useful to
+  be able to specify a restricted range of key tags to be used by an
+  operator to sign the zone. The range can be specified with
+  ``tag-range`` in :any:`dnssec-policy`'s :ref:`keys
+  <dnssec-policy-keys>` (for :iscman:`named` and :iscman:`dnssec-ksr`)
+  and with the new options :option:`dnssec-keyfromlabel -M` and
+  :option:`dnssec-keygen -M`. :gl:`#4830`

 Bug Fixes

-- Delay release of root privileges until after configuring controls.
+- Delay the release of root privileges until after configuring controls.
 
   Delay relinquishing root privileges until the control channel has been
   configured, for the benefit of systems that require root to use
   privileged port numbers.  This mostly affects systems without fine-
   grained privilege systems (i.e., other than Linux). :gl:`#4793`
 
-- Fix rare assertion failure when shutting down incoming transfer.

-  A very rare assertion failure can be triggered when the incoming
-  transfer is either forcefully shut down or it is finished during
-  printing the details about the statistics channel.  This has been

+- Fix algorithm rollover bug when there are two keys with the same
   keytag.
 
-  If there is an algorithm rollover and two keys of different algorithm
-  share the same keytags, then there is a possibility that if we check
-  that a key matches a specific state, we are checking against the wrong
-  key. This has been fixed by not only checking for matching key tag but
-  also key algorithm. :gl:`#4878`
