-4.4.3 is the final release for those components.

-While release 4.4.3 is primarily a maintenance release that addresses a number
-of issues, it does introduce a few new features:
-
-1. BIND libraries updated to the latest version, 9.11.36. This fixes a number 
-  of compilation issues on various systems, including OpenWRT.
-   [gitlab #218, #171, #180, #192]
-
-2. Improved PRNG initialization. There is now a new configure flag --with-randomdev=PATH
-  that specifies the device from which to read the initial seed. That is typically
-  /dev/random (the default value) or /dev/urandom, but may be other as preferred on
-  your system. If this option is enabled, dhclient will use the file as a seed. If
-  not, the previous algorithm (get last 4 bytes of hardware addresses from all network
-  interfaces that have them, use current time and process ID) will be used.
-
-3. The IPv6-only preferred option, defined in RFC8925, is now supported.
-   [gitlab #132]
-
-4. Compilation fixed for gcc-10.
-   [gitlab #117]
-
-5. Client fix: wrong argument to memcpy()
-   [gitlab #190]
-
-6. The server's limit on the size of lease file that can be loaded at start up
-   is now only enforced on 32-bit systems.
-   [gitlab #64]

-- After a report about predictable seeding of transaction identifier

-  random the already existing --with-randomdev configure argument was
-  extended. Please remember its default is "/dev/random" which is not
-  convenient on all systems.
+- The PRNG initialization has been improved. It now uses the configure flag
+  `--with-randomdev=PATH`, which specifies the device from which to read the
+  initial seed. That is typically `/dev/random` (the default value) or
+  `/dev/urandom`, but may be specified otherwise on the local system. If not
+  explicitly specified, the default device (`/dev/random`) is used. The old
+  behavior can be forced by disabling this feature (`--with-randomdev=no`).
+  If the initialization is disabled or reading from the random device fails,
+  the previous algorithm (retrieve the last four bytes of hardware addresses
+  from all network interfaces that have them, and use the current time and
+  process ID) is used.
