Changelog 8.0

Major changes

Behavior

Coming up in the next release:

Many users are familiar with vtysh's "walk up" behavior. If a command is entered which isn't valid in the current CLI context mode, vtysh will "walk up" to higher, more general contexts and attempt to evaluate the command there. In prior releases, this would happen if the command entered was ambiguous for the current context. This caused more problems than it was worth and so an upcoming release the behavior will be changed so that vtysh will no longer walk up when an ambiguous command is entered. Some users that have configurations which rely on this behavior may notice that their configurations no longer work. This should be a very small minority of users but please keep it in mind if you start seeing weird configuration issues in a future release. It's worth taking some time now to see if you're relying on ambiguous command walkup.

Features

A new daemon, pathd, has been added. This daemon implements support for segment routing. Documentation is currently lacking, but there are example configurations to look at here (http://docs.frrouting.org/en/latest/pathd.html).

EVPN Multihoming is now fully supported

OSPFv3 now supports VRFs

TI-LFA has been implemented in IS-IS and OSPF

Zebra now has the ability to dump netlink messages in a human-friendly format

LDP gained SNMP support

Dependencies

FRR uses libyang (https://github.com/CESNET/libyang) to implement support for YANG models and related functionality. In this release we've transitioned to libyang2 to provide both better performance and to receive better support from future libyang changes. Packaged libyang2 is provided in our Debian and RPM repositories.
