NOTE: The client and relay components are now End-Of-Life.
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]

[Gitlab #92]
- After a report about predictable seeding of transaction identifier
pseudo-random generation on systems where process identifiers are not
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.
