## [0.3.2] - 2018-12-26
|
||||
### Added
|
||||
- The admin socket is now multithreaded, greatly improving performance of the crawler and allowing concurrent lookups to take place
|
||||
- The ability to hide NodeInfo defaults through either setting the `NodeInfoPrivacy` option or through setting individual `NodeInfo` attributes to `null`
|
||||
|
||||
### Changed
|
||||
- The `armhf` build now targets ARMv6 instead of ARMv7, adding support for Raspberry Pi Zero and other older models, amongst others
|
||||
|
||||
### Fixed
|
||||
- DHT entries are now populated using a copy in memory to fix various potential DHT bugs
|
||||
- DHT traffic should now throttle back exponentially to reduce idle traffic
|
||||
- Adjust how nodes are inserted into the DHT which should help to reduce some incorrect DHT traffic
|
||||
- In TAP mode, the NDP target address is now correctly used when populating the peer MAC table. This fixes serious connectivity problems when in TAP mode, particularly on BSD
|
||||
- In TUN mode, ICMPv6 packets are now ignored whereas they were incorrectly processed before
|
||||
|
||||
## [0.3.1] - 2018-12-17
|
||||
### Added
|
||||
- Build name and version is now imprinted onto the binaries if available/specified during build

|

Given the coordinates of any two nodes, it is possible to calculate the length of some real path through the network between the two nodes.
|
||||
|
||||
Traffic is forwarded using a [greedy routing](https://en.wikipedia.org/wiki/Small-world_routing#Greedy_routing) scheme, where each node forwards the packet to a one-hop neighbor that is closer to the destination (according to this distance metric) than the current node.
|
||||
In particular, when a packet needs to be forward, a node will forward it to whatever peer is closest to the destination in the greedy [metric space](https://en.wikipedia.org/wiki/Metric_space) used by the network, provided that the peer is closer to the destination than the current node.
|
||||
In particular, when a packet needs to be forwarded, a node will forward it to whatever peer is closest to the destination in the greedy [metric space](https://en.wikipedia.org/wiki/Metric_space) used by the network, provided that the peer is closer to the destination than the current node.
|
||||
|
||||
If no closer peers are idle, then the packet is queued in FIFO order, with separate queues per destination coords (currently, as a bit of a hack, IPv6 flow labels are embedeed after the end of the significant part of the coords, so queues distinguish between different traffic streams with the same destination).
|
||||
Whenever the node finishes forwarding a packet to a peer, it checks the queues, and will forward the first packet from the queue with the maximum `<age of first packet>/<queue size in bytes>`, i.e. the bandwidth the queue is attempting to use, subject to the constraint that the peer is a valid next hop (i.e. closer to the destination than the current node).
