- in case of vulnerabilities.

## [0.3.0] - 2018-12-12
### Added
- Crypto-key routing support for tunnelling both IPv4 and IPv6 over Yggdrasil
- Add advanced `SwitchOptions` in configuration file for tuning the switch
- Add `dhtPing` to the admin socket to aid in crawling the network
- New macOS .pkgs built automatically by CircleCI
- Add Dockerfile to repository for Docker support
- Add `-json` command line flag for generating and normalising configuration in plain JSON instead of HJSON
- Build name and version numbers are now imprinted onto the build, accessible through `yggdrasil -version` and `yggdrasilctl getSelf`
- Add ability to disable admin socket by setting `AdminListen` to `"none"`
- `yggdrasilctl` now tries to look for the default configuration file to find `AdminListen` if `-endpoint` is not specified
- `yggdrasilctl` now returns more useful logging in the event of a fatal error
### Changed
- Switched to Chord DHT (instead of Kademlia, although still compatible at the protocol level)
- The `AdminListen` option and `yggdrasilctl` now default to `unix:///var/run/yggdrasil.sock` on BSDs, macOS and Linux
- Cleaned up some of the parameter naming in the admin socket
- Latency-based parent selection for the switch instead of uptime-based (should help to avoid high latency links somewhat)
- Real peering endpoints now shown in the admin socket `getPeers` call to help identify peerings
- Reuse the multicast port on supported platforms so that multiple Yggdrasil processes can run
- `yggdrasilctl` now has more useful help text (with `-help` or when no arguments passed)
### Fixed
- Memory leaks in the DHT fixed
- Crash fixed where the ICMPv6 NDP goroutine would incorrectly start in TUN mode
- Removing peers from the switch table if they stop sending switch messages but keep the TCP connection alive
## [0.2.7] - 2018-10-13
### Added
- Session firewall, which makes it possible to control who can open sessions with your node

%description
Yggdrasil is a proof-of-concept to explore a wholly different approach to
network routing. Whereas current computer networks depend heavily on very
centralised design and configuration, Yggdrasil breaks this mould by making
use of a global spanning tree to form a scalable IPv6 encrypted mesh network.
