* 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

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.
* 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
* 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
* syntax in 50-ypbind hook has been fixed
* man page corrections
* report hwaddr used by dhcpcd when debug is enabled
* Fix detecting inet address for INFORM support
* document reason RELEASE in dhcpcd-run-hooks
* Support RTM_CHGADDR in the upcoming NetBSD-6
This is used to work out if the hwaddr has changed as the interface
does not go down/up unlike other OSes
* ntp hook no longer attempts to restart ntpd if 1st attempt failed
* -H, --xidhwaddr uses the last 4 bytes of the hardware address as
the DHCP xid
* -J, --broadcast tells the DHCP server to broadcast replies
* no longer warn about InfiniBand being an unsupported family
* infinite lease times are valid when reading old leases
* discard address correctly if lease is invalid
* ClientID is now reported when interface starts.
* -w, --wait forces dhcpcd to wait until an interface gets a lease or
times out.
* Ensure DHCP socket is open when sending a DECLINE.
* Uses new hwaddr if existing interface is downed and then changed.
* No longer works on firewire interfaces by default.
dhcpcd-5.1.2 has a new behaviour change - when starting up and at least 1
interface has a carrier then it tries to get a lease or times out.
It still daemonises regardless. This, along with the -b and -w flags
allows total control over the desired behaviour of dhcpcd.
Changes from dhcpcd-5.0.7 include
* Only allow hardware families we know by default (over-ridable)
* Fix persistent and timeout 0 options
* Fix parsing of escape code sequencies
* Don't bring up interfaces brought down when handling new interfaces
* Allow un-encapsulated vendor option
* Don't null terminate gratuitously when handling quotes
* Fix various typos and grammatical errors
* dhcpcd.conf simplified a little
Changes from dhcpcd-5.0.6 include:
* Fix -f path/to/config
* -e, --env var=value for profile specific env vars
* Many issues resolved when running in test mode
* Don't print a (null) string when there is no NAK message
* read ssize_t instead of size_t when checking signals
Changes from dhcpcd-5.0.5 include
* Fix crash on MIPS, fixes PR bin/41682
Thanks to Tim McIntosh <tmcintos@eskimo.com> for the patch
* Save and restore interface MTU when changing
* IP whitelist
* Ensure that the lease and pidfile directories exist at startup
Major changes from dhcpcd-4 include
* Single daemon can now run DHCP on multiple interfaces at the same time
* Configuration profiles per interface, ssid, arping and fallback
* Listens to 3rd party programs changing routing information
* Supports DHCP INFORM over PPP
* Can configure static options for destination address
* Control socket so 3rd party program can control or listen directly
to dhcpcd events
* Is also a BOOTP client
Fixed since dhcpcd-4.0.12 include
* Every DHCP message now requires a ServerID as some rogue DHCP servers
NAK without one.
* Extra UDP validation is now done for testing dhcpcd over a loopback
DHCP_DECLINE now includes the IP and Server in the message.
Trailing NULLs are stripped from string options.
ntpd is only restarted if it is already running.
ClientID is no longer sent by default.
CSR comes before routers and static routes as per RFC 3442.
Host routes are now added correctly.
If a the interface link flaps but status does not change, do not reset the timer.
- basic resolvconf like functionality to combine the resolv.conf entries
from running instances
- improve timer handling to not break with early wake ups and other edge
cases related to the kernel time granularity
- improve handling of dhcpcd -n and rebinding after carrier loss to
better deal with changing networks
- add option to black list servers based on server id
- don't check for ARP conflict if the interface already has the address
- improve signal handling during vfork/exec
- support for link state notification (e.g. renew lease after carrier
returned)
- support to start go into background immediately
- don't cleanup interface state. dhcpcd will leave the interface in the
same state as before if the lease uses separate addresses. -p still
stops it from removing the configured address on exit
- various smaller bugfixes, optimisations and cleanups
