OpenBGPD 8.4 released

We have released OpenBGPD 8.4, which will be arriving in the
OpenBGPD directory of your local OpenBSD mirror soon.

This release includes the following changes to the previous release:

* 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.

OpenBGPD-portable is known to compile and run on FreeBSD and the
Linux distributions Alpine, Debian, Fedora, RHEL/CentOS and Ubuntu.
It is our hope that packagers take interest and help adapt OpenBGPD-portable
to more distributions.

We welcome feedback and improvements from the broader community.
Thanks to all of the contributors who helped make this release
possible.
