* Fixed a segfault when configuring a static route in dhcpcd.conf
* Merged IPv6 ND and RA codebases
* Persistent configuration is now a default option in dhcpcd.conf
* Store configured IPv4 addresses against the interface so we only add
them if actually missing to avoid RTM_DELADDR/NEWADDR loops on some OS's
* waitip now supports waiting for any, IPv4, IPv6 or both protocols
* DHCPv6 addresses are added with a /128 prefix and should not attempt to
associate with any existing prefix or make one up as per RFC 5942
* Fix initial carrier status
* Fix requesting >1 DHCPv6 address
Fixes PR bin/48140
* hostname is not stamped on anymore if already set
* hostname will be set to a FQDN when possible as per RFC4702 section 3.1
* a domain is derived from the FQDN if no domain option is set
* add new hostname_short command to send a short hostname for DDNS
* hostname_fqdn is now documented, along with a new server setting and the
potential problems associated with it
* the FQDN option is no longer sent by default for DHCPv4 messages
* dhcpcd will now assign a short hostname by default
To use a FQDN hostname, set this in dhcpcd.conf(5)
env hostname_fqdn=YES
* Only start DHCPv6 if the RA is new or has changed
* Fixed dhcpcd owning RA addressing and routes if disabled in kernel
* DHCPv6 support
* wpa_supplicant hook script
* route IPv4 addresses to 127.0.0.1 for machine centric traffic
* DHCPv6 Prefix Delegation support
* DHCPv6 FQDN support
* Control existing IPv4 routes
* less spamy to syslog by default
* IPv6 protocols now wait for a valid LL address before starting
* IPv6 DAD support now listens to kernel for more accurate timings
* IPv4 code split out more cleanly so dhcpcd can be compiled for
IPv4, IPv6 or IPv4 AND IPv6
* MTU is no longer requested by default
* a DUID is now generated in /etc/dhcpcd.duid and this is used as a
client ID for DHCPv4 and DHCPv6
This does mean that you may get new DHCPv4 addresses
Many bugs have also been fixed along the way and this release addresses

* Preserve space in static routes on the command line.
* Check correct interface the RAP came from; fixes PR bin/47433 thanks to
Taylor R Campbell
* Ensure the nooption works for IPv4 routes
* add interface scope to exported IPv6 link local addresses
* DUID feature works again
* If we receive >1 MTU in the RA we use the last one
* Expire RA options separately from the RA
* Merge multiple RA options together except when a single is needed
* Some memory leaks plugged
* Don't overwrite invalid memory when DNSSL options begin with a NULL
* Ensure we have a large enough buffer for an escaped DNSSL option from RA
Disable kernel RA earlier on Linux
* Don't set if_up or if_down as true when testing
* ra%d_prefix is now a space separated array of the finished address/len
* If we fail to open sockets, don't bother sending the request
* Send our NS solicitation directly to the router
* Change the NS times so that we assume reachable until the reachable time
expires, then send probes at retrans intervals until
DELAY_FIRST_PROBE_TIME is reached at which point we expire the router
* Remove -v from --version in usage
* Only add our own host or destination routes to the build table when we
are adding gateways
* Ensure we have correct memory allocation for each prefix in the RA
Improve IPv6 RA support by allowing dhcpcd to manage addreses and
routes instead of the kernel. dhcpcd will only do this if RA has been
disabled in the kernel or instructed to do so via the dhcpcd.conf(5)
ipv6ra_own and/or ipv6ra_owndefault directives.
Send and process IPv6 Neighbor Solicitions and Adverts to prove router
reachability. If a router cannot be reached in this way then it is
expired.
* Add a suffix to all our config files so that RA never stamps on IPv4
* All valgrind errors fixed on FreeBSD (with ./configure --debug=YES)
* When started with an interface list, respect that with signal handling
* Fix a potential route table corruption if we failed to add a route
New sentence, new line.
Sort options and option descriptions.
Sort SEE ALSO.
Use Fl Fl for long options.
Comment out --version description which binary doesn't support.
* We store the RA against the interface so we can do a comparsion
so we don't spam the log frequently.
* By default only fork on RA if it has a valid RDNSS option
* Add .Lk macros to the man pages
* Use correct event loop calls in RA handling code
* Fix several memory overrun issues
* Use CSR more than once
* Allow operation on Bridge and VLAN interfaces
* Disregard IFF_RUNNING on link state changes
* Warn about the kernel not configured for IPv6 RAs instead of
complaining it can't send messages
OK: releng@
* Stop checking IFF_RUNNING in RTM_IFINFO in an unknown link state
* RA expiry now tiggers off the first option if newer than the prefix
* Prefer a DHCP lease over an IPv4LL one
* Don't start IPv6 RS if disabled globally
* Allow dhcpcd to run on a read only filesystem
* Don't attempt to run the script if an empty string or /dev/null
* Stop truncating the netmask sockaddr on routing messages for BSD
* Shell portability fixes, including proper printf usage.
* Detect a valid ntp.conf before adjusting it
* reboot timeout changed to 5 seconds
* When rebooting and not daemonized, reduce the discover timeout
to allow for fallback or IPv4LL
* Respect each kernel carrier message
* Optimize some bitwise logic
* Don't remove interfaces for which commands have not been sent
* Store the assigned metric to each route so that we can change metrics on the fly
dhcpcd -n --metric 100 iwi0
* Add SixRD support, RFC5969
* Fix SIP server support
* Only regen resolv.conf if it has changed
* Fix --reconfigure from spinning
* Add IPv6 Router Solicitation support we regards to RDNSS and DNSSL, RFC6016
* 20-resolv.conf now uses the correct variable for $IF_METRIC
* Exclude interface values when dumping the lease
* Parse static value subnet_mask when it exists instead of deriving from
ip address
* logger calls now resemble dhcpcd calls to syslog(3)
* Reject offered IP address if INADDR_BROADCAST or INADDR_ANY
* Change the route if source address has changed
* Note the address we are requesting in the broadcast log entry
* When operating on one interface, respect the timeout for in dhcpcd.conf
* Escape | and & characters before passing the value to the shell
Ensure we set a valid hostname, DNS domain and NIS domain.
Document the need for input validation in dhcpcd-run-hooks(8).
