lldpd (1.0.7)
  * Fix:
    + Do not listen only to LLDP packets on Linux. When an interface
      is enslaved to an Open vSwitch, incoming packets are missed.

lldpd (1.0.6)

  * Fix:
    + Don't clear chassis TLV on shutdown LLDPDU.
    + Don't require/display powerpairs for Dot3 power when device type
      is PD.

lldpd (1.0.4)

    + Add "configure system max-neighbors XX" command to modify maximum
      of neighbors accepted per port.
    + Implement lldpRemOrgDefInfoTable table for custom TLVs.
  * Fix:
    + Better compliance for statsTLVsUnrecognizedTotal and
      statsAgeoutsTotal counters.
    + On Linux, handle rare blocking case in Netlink code.

lldpd (1.0.3)
  * Fix:
    + Fix creation of chroot directory.

lldpd (1.0.2)
  * Changes:
    + On Linux, the monitor process will now drop its privileges
      instead of running as root. It will keep CAP_NET_RAW,
      CAP_NET_ADMIN and CAP_DAC_OVERRIDE capabilities.
    + Support for CDP PD PoE (with negotiation). Thanks to Gustav
      Wiklander.
    + Move support for bonded devices on Linux < 2.6.27 into the
      `--enable-oldies` option. This avoids duplicate packets
      starting from Linux 4.19.

lldpd (1.0.1)
  * Fix:
    + Use "mkdir -p" instead of "mkdir" in systemd unit.

lldpd (1.0.0)
  * Changes:
    + Chassis ID can be set to an arbitrary value with "configure system
      chassisid".
    + Port description can be overriden directly with "configure lldp
      portdescription".
    + Command "configure system interface permanent" enables one to
      specify a pattern for interfaces to be kept in memory even when
      they are removed from the system.
  * Fix:
    + Ensure chassis-related changes are propagated immediately.
    + Ensure management address change is correctly detected.

lldpd (0.9.9)
  * Changes:
    + lldpcli can now display local interfaces with LLDP data sent on
      each of them ("show interfaces").
    + As Dot3 PD device, echo back allocated value from PSE device.
  * Fix:
    + Don't remove interfaces when they are released from a bridge.
    + Don't use "expect stop" with Upstart. It's buggy.

lldpd (0.9.8)
  * Changes:
    + "Station" capability is only set if no other bit is set.
    + Use ethtool to get permanent address for bonds and teams. This
      might provide different results than the previous method. Some
      devices may still use the previous method.
    + Don't run ethtool as root. Kernels older than 2.6.19 won't get
      link information anymore.
    + Add "configure system hostname ." option to not use a FQDN
      for system name.
    + Add "-f json0" to provide a more regular/machine-parsable output
      to JSON output, even when not compiled with --enable-json0.
  * Fixes:
    + Handle team interfaces like a bond. Real MAC address cannot be
      retrieved yet.

lldpd (0.9.7)
  * Changes:
    + Attach remote TTL to port instead of chassis.
    + JSON support is now built-in and unconditionally enabled. Use
      --enable-json0 to keep the pre-0.9.2 json-c format.
    + When logging to syslog and daemonizing, don't log to stderr.
    + vxlan interfaces are now ignored as they are multi-point interfaces.
    + Maximum number of neighbors for an interface is increased from 4 to 32.

lldpd (0.9.6)
  * Changes:
    + Add a compile-time option to restore pre-0.9.2 JSON format (when
      using json-c). Use `--enable-json0` to enable this option.
    + Support for newer ethtool interface on Linux
      (ETHTOOL_GLINKSETTINGS) and additional speed settings.
    + Current MAU type is displayed even when autoneg is off.
    + Increase netlink receive buffer by default. Can be changed at
      compile-time through ./configure.
  * Fixes:
    + Correctly parse LLDP-MED civic address when the length of the
      TLV exceeds the length of the address.
    + Fix 100% CPU on some rare error condition.
    + Fix lost timer when an interface is enslaved on Linux.

lldpd (0.9.5)
  * Changes:
    + More Ethernet media supported. However, RFC4836 is quite
      out-of-date with respected to 10G+ speeds, bringing some
      inaccuracies.
    + Directly get media information for an interface without using
      the privileged process.
    + LLDP-MED capability TLV is not sent when LLDP-MED is not enabled,
      even if other LLDP-MED TLV are present.
  * Fixes:
    + Compilation fix with older versions of GCC.
    + Don't use ethtool at all to get real MAC address for enslaved
      devices (always use /proc).

lldpd (0.9.4)
  * Changes:
    + Make lldpd accepts a `-p` option to specify the PID file.
    + Ability to change multicast MAC address to two additional values
      to reach customer bridges.
    + lldpcli will now display chassis TTL when detailed view is enabled.
  * Fixes:
    + Fix setting of local value for port ID.
    + Fix compilation with BSD make.
    + Ensure lldpcli returns an error code on invalid commands.

lldpd (0.9.3)
  * Changes:
    + Do not rely on support of constructors for liblldpctl.
    + Always log to stderr (even in addition to syslog).
    + `lldpcli watch` accepts a limit on the number of received events.
  * Fixes:
    + `lldpcli -f {xml,json} watch` should work now.
    + Consider `veth` interfaces as physical interfaces.

lldpd (0.9.2)
  * Changes:
    + Ability to add/remove/replace custom TLV from lldpcli.
    + LLDP-MED capabilities are displayed differently in lldpcli.
    + Limit the maximum depth (5) when trying to apply a VLAN.
    + Change JSON output format when using json-c to match Jansson
      output.
    + Integration tests for the major parts of lldpd, including use of
      address and leak sanitizer.
  * Fixes:
    + LLDP-MED POE TLV are now displayed in lldpcli.
    + Ignore lower link when it is in another namespace.
    + Fix various problems with interfaces being enslaved.
    + Fix a memory leak when modifying port-related settings.

lldpd (0.9.1)
  * Changes:
    + Rework packaging for OS X to make it work with El Capitan. To
      simplify a bit, it is not possible anymore to build fat
      binaries. Latest version of OS X supporting 32bit was 10.6.
  * Fixes:
    + By default, when using port alias as description, use port name
      as port ID.
    + Miscellaneous fixes with netlink cache.
    + Ensure large netlink messages can be received.

lldpd (0.9.0)
  * Changes:
    + Don't rely on libnl3 for netlink. Reuse the previous code and
      implement a lighweight cache.

lldpd (0.8.0, never released)
  * Changes:
    + PIE is now disabled by default. It's too difficult to reliably
      detect if it works. Use --enable-pie to enable it.
    + Retrieve the permanent MAC address of an interface through
      ethtool for Linux if /proc/net/bonding is not available.
    + Running lldpd with "-d" will keep the process in foreground but
      logs will still go to syslog. To log to the console, add at
      least one "-d".
    + Fix minimal kernel version to 2.6.39. Add a runtime warning when
      this is not the case.
    + Remove old bridge code (the one using ioctl).
    + Don't discard down interfaces. Notably, this enables us to keep
      their specific configuration if any.
    + For Linux, switch to libnl3. Be aware of the licensing issues in
      case of static linking.
    + Introduce the notion of default local port. New interfaces will
      use it as a base. This allows setting various MED stuff.
    + Provide an apparmor profile (untested).
  * Fixes:
    + Fix a buffer overflow when receiving a too large management
      address TLV. Unless hardening has been disabled, this overflow
      cannot be used for arbitrary code execution.
    + Update LLDP-MED policy L2 priority values to match
      802.1Q-2005. This may be a breaking change.

lldpd (0.7.17)
  * Fixes:
    + Fix the way libevent configure is called.
    + Fix an infinite loop when using veth on Linux 4.1+ kernels.
    + Make CDP advertise the appropriate kernel name as platform,
      not just "Linux".

lldpd (0.7.16)
  * Changes:
    + For Linux, 2.6.32 is now the minimal required kernel. When using
      an older kernel, use `--enable-oldies`.
    + For Linux, use netlink to retrieve information about bridges,
      VLAN and bonds. The code was contributed by Cumulus Networks.
    + Use symbol versioning for liblldpctl.so.
    + Ability to get local chassis information with "show
      chassis".
    + The library also has the same ability with the
      `lldpctl_get_local_chassis()` function. It is also possible to
      get a chassis atom from a port with `lldpctl_k_port_chassis`
      key. This is now the preferred way to retrieve chassis related
      information.
  * Fixes:
    + Fix build on OS X.
    + Accept "language" when configuring MED location as a civic address.

lldpd (0.7.15)
  * Changes:
    + Optional features can be configured with "auto" to autodetect if
      they are usable. This is the default value for JSON and XML support.
    + Ability to send and decode custom/unknown TLV. Thanks to Alexandru
      Ardelean.
    + Modify checksum function. While this should be strictly
      equivalent, if you notice CDP packets not accepted anymore, this
      change is the first culprit.

lldpd (0.7.14)
  * Changes:
    + Shutdown LLPDU are sent on MSAP change and when lldpd exits.
    + When an exact IP is provided as a management pattern, use it
      unconditionally.
    + Ability to set port ID and description to an arbitrary value,
      thanks to Alexandru Ardelean.
  * Fixes:
    + Incorrect boundary check when decoding management address and
      protocol identity may lead to lldpd crash when processing
      malformed LLDPDU.
    + Many edge cases where lldpd was leaving hanging processes after
      crashing.

lldpd (0.7.13)
  * Fixes:
    + Unbreak customization of Unix socket path from command line.

lldpd (0.7.12)
  * Changes:
    + Interface pattern, management pattern, system description,
      system platform and system hostname can be unconfigured to their
      default values.
  * Fixes:
    + Don't complain when parsing a commented line.
    + Correctly persist configuration changes for "system interface
      promiscuous", "system interface description" "med fast-start
      enable", "pause" and "resume".
    + Fix listening on bond devices for old kernels (< 2.6.27).

lldpd (0.7.11)
  * Changes:
    + Ship bash and zsh completion.
    + Abort when some command-line options are repeated.
  * Fixes:
    + Handle correctly read failures in liblldpctl.

lldpd (0.7.10)
  * Changes:
    + Ability to set promiscuous mode to work around bugs of some
      switches encapsulating LLDP frames inside 802.1Q frames.
    + JSON support for lldpcli can use json-c instead of jansson,
      thanks to Michel Stam.
  * Fixes:
    + Fix checksum computation for Cisco CDP.
    + Fix ability to disable LLDP.
    + Fix seccomp sandbox, thanks to Patrick McLean.

lldpd (0.7.9)
  * Changes:
    + Default location for chroot, socket and PID are now configurable
      in `./configure`. The default location is based on the value of
      `runstatedir` which in turn may be based on the value of
      `localstatedir` which defaults to `/usr/local/var`. Therefore,
      to get the previous locations, lldpd should be configured with
      `./configure --localstatedir=/var`.
    + Add support for shutdown LLDPU.
    + Ability to configure IP management pattern from lldpcli.
    + Ability to choose what port ID should be (MAC or interface name).
  * Fixes:
    + Fix `configure system bond-slave-src-mac-type local`. Also use
      it as default.

lldpd (0.7.8)
  * Changes:
    + Android support
    + Add the possibility to disable privilege separation (lower
      memory consumption, lower security, don't do it).
    + Interfaces can now be whitelisted. For example, *,!eth*,!!eth1
      is a valid pattern for all interfaces except eth ones, except
      eth1. Moreover, on exact match, an matching interface
      circumvents most sanity checks (like VLAN handling).
    + Ability to override the hostname.
  * Fixes:
    + Don't hard-code default values for system name, system
      description and port description. When the field is not present,
      just don't display it.
    + Fix lldpcli behaviour when suid.
    + On OSX, don't use p2p0 interfaces: it would break WLAN.
    + Fix SNMP support on RHEL.

lldpd (0.7.7)
  * Changes:
    + Use a locally administered MAC address or an arbitrary one
      instead of null MAC address for bond devices on Linux. This is
      configurable through `lldpcli`.
    + Add support for "team" driver (alternative to bond devices).
    + Preliminary support for DTrace/systemtap.
    + Preliminary support for seccomp (for monitor process).
    + Setup chroot inside lldpd instead of relying on init script.
  * Fixes:
    + Various bugs related to fixed point number handling (for
      coordinates in LLDP-MED)
    + Fix a regression in how MAC address of an enslaved device is
      retrieved.

lldpd (0.7.6)
  * Changes:
    + Provide a way to build packages for OSX.
    + Add an option to update interface description with neighbor name.
  * Fixes:
    + Compilation fix for OSX 10.6.

lldpd (0.7.5)
  * Fixes:
    + Segfault while tokenizing in lldpcli.

lldpd (0.7.4)
  * Fixes:
    + Segfault in lldpcli.
    + Memory leak in liblldpctl when using a custom log handler.
    + Fix some unaligned memory accesses.
    + Fix frame reception on OpenBSD.
  * Changes:
    + Allow to configure hold value from lldpcli (and hence the TTL).
    + Allow to configure pattern for valid interfaces from lldpcli.
    + Allow to override system description from lldpcli.
    + Display the neighbor connected as the process title (or the
      number of connected neighbors).

lldpd (0.7.3)
  * Changes:
    + DragonFly BSD support.
    + Solaris support (incomplete).
    + LLDP-MED fast start support (thanks to Roopa Prabhu).
    + Provide global statistics through "show statistics summary"
      command (thanks to Roopa Prabhu).
  * Fixes:
    + Fix IPv4/IPv6 address discovery in Linux.

lldpd (0.7.2)
  * Changes:
    + lldpd can be configured through /etc/lldpd.conf and
      /etc/lldpd.d. All commands accepted by lldpcli are accepted.
    + Lock BPF interfaces before handing them to chrooted process on
      BSD.
    + Limit the number of neighbors for each port to 4 (per protocol).
    + Force CDPv2 protocol with argument `-ccc`.
    + Provide port statistics through "show statistics" command
      (thanks to Roopa Prabhu).
  * Fixes:
    + Driver whitelisting is done before checking if an interface has
      a lower interface in Linux.
    + Expire remote ports and chassis in a timely manner.

lldpd (0.7.1)
  * Changes:
    + Mac OS X support, sponsored by Xcloud, Mac cloud server hosting
      provider. http://xcloud.me/
    + Upstart and systemd support.
    + Remove Unix socket when there is no process listening.

lldpd (0.7.0)
  * Changes:
    + FreeBSD support.
    + OpenBSD support.
    + NetBSD support.
    + Detect interface changes.
    + CLI for lldpctl: lldpcli.
    + Allow to disable LLDP protocol (with `-ll`). In this case, the
      first enabled protocol will be used when no neighbor is detected.
    + Allow to filter debug logs using tokens. Add more debug logs.
    + lldpctl can now output JSON.
    + Use netlink to gather interface information on Linux.
    + Don't use ioctl for bridges anymore on Linux. The configure
      option `--enable-oldies` allow to reenable their uses for
      systems not supporting sysfs.

lldpd (0.6.1)
  * Changes:
    + Provide liblldpctl.so, a library to interface with lldpd. The
      documentation is provided through Doxygen. See src/lib/lldpctl.h
      which contains all the exported functions.
    + Make lldpctl uses liblldpctl.so.
    + Add a "watch" option to lldpctl to monitor neighbor changes.
    + Add the possibility to display the current configuration of
      lldpd with lldpctl. Also add the possibility to reset the
      current transmit delay.

lldpd (0.6)
  * Changes:
    + Allow lldpctl to display hidden ports.
    + Add a switch to specify interfaces to use to get chassis ID.
    + Support for multiple management addresses and IPv6 management
      addresses. Contributed by João Valverde.
    + Switch to libevent. See README.md for details.
    + Partial rewrite of the SNMP part. Less code.
    + Unit tests for SNMP.
    + Major rewrite of the protocol between lldpd and lldpctl. Less
      code.
  * Fixes:
    + Several small SNMP fixes (discovered by unit tests).

lldpd (0.5.7)
 * Fixes:
    + Configure issue with NetSNMP and some linkers
    + Fix infinite loop for the receive part: on certain conditions,
      lldpd will stop sending packets and stop updating local data.

lldpd (0.5.6)
  * Changes:
    + Send and receive native VLAN TLV with CDP
    + Add a whitelist for some drivers (currently: dsa and veth)
  * Fixes:
    + Compilation issues with NetSNMP 5.7 (and with earlier versions too)
    + Small optimization of BPF filter

lldpd (0.5.5)
  * Changes:
    + Support for PPVID and PI Dot1 TLV, thanks to Shuah Khan.
    + Extend whitelist with possibility to blacklist.
  * Fixes:
    + Key/value output was incorrect when a dot was present in
      interface names. This is fixed but it is preferable to use XML
      output since the parsing is more difficult in this case.
    + Only grab DMI information once. Only uses DMI for x86 platform.
    + Padding issues with socket protocol. This introduces a change in
      the socket protocol!
    + Fix a segfault when neither /etc/os-release nor lsb_release
      are available.

lldpd (0.5.4)
  * Changes:
    + Get OS information from /etc/os-release if available. Patch from
      Michael Tremer.
    + Add a flag to specify which interfaces lldpd should listen to.

lldpd (0.5.3)
  * Changes:
    + Handle Dot3 POE-MDI TLV (802.3af and 802.3at).
    + Allow to set Dot3 POE-MDI from lldpctl.
  * Fixes:
    + Allow root to change configuration of lldpd when lldpctl has suid set.

lldpd (0.5.2)
  * Changes:
    + More flexible smart mode and new default. Manual page has been updated.
    + Add a "receive-only" mode with "-r" switch.

lldpd (0.5.1)
  * Changes:
    + Allow to force a protocol even when no peer for this protocol is
      detected.
    + Add a smart mode that allows to discard bogus port information,
      for example CDP packets that are flooded through a switch that
      does not support CDP.
    + Allow to set LLDP-MED network policy from lldpctl, thanks to a patch from
      Philipp Kempgen.
    + Allow to set LLDP-MED POE-MDI from lldpctl.
    + Add a summary of available options in "lldpd -h" and "lldpctl -h",
      thanks to a patch from Jorge Boncompte.
    + Add a new output (keyvalue) for lldpctl.
    + Listen on VLAN using an appropriate BPF filter, VLAN
      decapsulation. Older "listen on vlan" feature is discarded. See
      README for more information on the new feature.
    + Use output of lsb_release if available for system description.
  * Fixes:
    + Ignore interface with no queue. It should filter out interfaces
      like "vnet0" that would fail if we try to send something on them.
    + Don't check CDP checksums (not really a fix but it appears that
      Cisco checksum have some difficult corner cases).

lldpd (0.5.0)
  * Changes:
    + lldpd can now handle several systems on the same port. This
      modification also allows to speak to a switch using CDP and LLDP
      for example.
    + The way that lldpd gathers information for each port has been
      abstracted. This should allow to support more systems (BSD for
      examples) or switch cores in the future. Sending/receive support
      is also abstracted.
    + Add "-k" switch to avoid to emit too much information on running
      kernel.
    + Support of ifAlias with kernel >= 2.6.28
    + Lot of portability stuff. lldpd can now be compiled on RHEL
      2.1. Still Linux-only though.
    + Add an option to specify AgentX socket (-X).
    + Add some unit tests
    + lldpctl has been reworked; it is now able to output data in XML
      format for easier parsing. Patches were provided by Andreas
      Hofmeister.
  * Fixes:
    + Fix EDP VLAN handling
    + Silent warnings about bridge stuff.
    + Copy /etc/localtime into chroot before starting lldpd daemon to
      ensure correct timestamps for logs.

lldpd (0.4.1)
  * Fix EDP handling when there is no VLAN

    step.
