* FRRouting 2021 GSOC Project

  FRRouting's GSOC student implemented the infrastructure needed to add the
  ability to call out to user provided Lua scripts from within FRR. Keep an eye
  out for developments in this area.

  You can read about the work he did here:

  Thank you @dlqs!

* Behavior Changes

- Every node in running config now has an explicit "exit" tag
- Link bandwidth in BGP is now correctly encoded according to IEEE 754.
  To stay with old incorrect encoding use:
  `neighbor PEER disable-link-bw-encoding-ieee`
