v0.1.3

Added

• Add info log when next hop of a peer changes.
• Add windows builds to CI.

Changed

• When printing the connected peers, print the underlay IP instead of the overlay IP.
• The link cost of a peer is now the smoothed average. This makes sure a single short latency spike doesn't disrupt routing.
• On Linux, set the TUN ip as /7 and avoid setting a /64 route. This brings it in line with OSX.
• When selecting the best route for a subnet, consider the currently
  installed route and only switch if it is significantly better, or
  directly connected.
• Increase the static link cost component of a peer. This will increase
  the value of a hop in the metric of a route, in turn increasing the
  impact of multiple hops on route selection. The route selection will
  thus be more inclined to find a path with fewer hops toward a
  destination. Ultimately, if multiple paths to a destination exist with
  roughly the same latency, they one with fewer hops should be
  preferred, since this avoids putting unnecessary pressure on multiple
  nodes in the network.
• IHU packets now include the underlay IP instead of the overlay IP.
• When a new peer connects the underlay IP is logged instead of the
  overlay IP.

Fixed

• Ignore retraction updates if the route table has an existing but retracted route already. This fixes
  an issue where retracted routes would not be flushed from the routing table.

Removed

• All uses of the exchanged overlay IP in the peer handshake are fully
  removed. Handshake is still performed to stay backwards compatible
  until the next breaking release.
