## 8.4 - 2024-03-07
    * Rewrite the internal message passing mechanism to use a new
      memory-safe API.

    * Rewrite most protocol parsers to use the new memory-safe API.
      Convert the UPDATE parser, all of RTR, as well as both the MRT
      dump code in bgpd and the parser in bgpctl.

    * Improve RTR logging, error handling and version negotiation.

    * Switch to autoconf 2.71 to generate the supplied configure scripts.


## 8.3 - 2023-10-13
    * bgpd 8.1 and 8.2 could send a bad COMMUNITY attribute when
      non-transitive ext-communities are present. A workaround is to
      add a filter rule to clear non-transitive ext-communities:
            match to ebgp set ext-community delete ovs *
      This fix is included in OpenBSD 7.4.

    * Fix a possible fatal error in the RDE when "announce add-path send all"
      is used. The error is triggered by an ineligible path which is wrongly
      distributed.

    * Fix selection of the local nexthop for the alternate address family.
      This is used by 'announce IPv6 unicast' over an IPv4 session or
      vice-versa.


## 8.2 - 2023-10-02
    * Update ASPA support to follow draft-ietf-sidrops-aspa-verification-16
      and draft-ietf-sidrops-aspa-profile-16 by making the ASPA lookup
      tables AFI-agnostic.

    * Fix a fatal error in the Linux netlink parser which was triggered
      because of a mismatched netlink message size.

    * Rework UPDATE message generation to use the new ibuf API instead
      of the hand-rolled solution before. 

    * Improve error message in bgpctl for features not supported by the
      portable version of OpenBGPD.

    * Adjusted example GRACEFUL_SHUTDOWN filter rule in the example config
      to only match on ebgp sessions.

## 8.1 - 2023-07-12
    * Include OpenBSD 7.3 errata 002:
      Avoid fatal errors in bgpd(8) due to incorrect refcounting and
      mishandling of ASPA objects. Fix bgpctl(8) 'show rib in' by renaming
      'invalid' into 'disqualified'.

    * Include OpenBSD 7.3 errata 006:
      Incorrect length handling of path attributes in bgpd(8) can lead to a
      session reset.

    * Include OpenBSD 7.3 errata 009:
      When tracking nexthops over IPv6 multipath routes, or when receiving
      a NOTIFICATION while reaching an internal limit, bgpd(8) could crash.

      When checking the next hop for IPv6 multipath routes, or when receiving
      a NOTIFICATION while reaching an internal limit, bgpd(8) could crash.

    * Add configure options to adjust WWW_USER and wwwrunstatedir.

    * Fix 'ext-community * *' matching which also affects filters removing
      all ext-commuinites.

    * Limit the socket buffer size to 64k for all sessions.
      Limiting the buffer size to a reasonable size ensures that not too many
      updates end up queued in the TCP stack.


## 8.0 - 2023-05-04
    * Include OpenBSD 7.3 errata 001 (link: https://www.openbsd.org/errata73.html#p001_bgpd):
      A new ASPA object appeared in the RPKI ecosystem and exposed bugs in
      bgpd(8) and rpki-client(8).

    * Introduce a semaphore to protect intermittent RTR session data 
      from being published to the RDE.

    * Add first version of flowspec support. Right now only announcement
      of flowspec rules is possible.

    * Improve and extend the bgpctl parser to handle commands like
      `bgpctl show rib 192.0.2.0/24 detail`. Also add various flowspec
      specific commands.
