-Updated core library to 0.5.9, presenting these changes:
-
-Changed
-The routing algorithm has been updated with RTT-aware link costing, which should prefer lower latency links over higher latency links where possible
-The calculated cost is an average of the link RTT, but newly established links are costed higher to begin with, such that unstable peerings can be avoided
-Link costs are only used where multiple next-hops are available and will be ignored if there is only one loop-free path to the destination
-This is protocol-compatible with existing v0.5.x nodes but will have the best results when peering with nodes that are also running the latest version
-The getPeers endpoint will now report the calculated link cost for each given peer
-Upgrade dependencies
-
-Fixed
-Multicast discovery should now work again when building Yggdrasil as an Android framework
-Multicast discovery will now correctly ignore interfaces that are not marked as running
-Ephemeral links, such as those added by multicast, will no longer try to reconnect in a fast loop, fixing a high CPU issue
-The TUN interface will no longer stop working when hitting a segment read error from vectorised reads
-The AllowedPublicKeys option will once again no longer apply to multicast peerings, as was originally intended
-A potential panic when shutting down peering links has been fixed
-A redundant system call for setting MTU on OpenBSD has been removed

-Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network.

-Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.

-This app allows you to connect to Yggdrasil Network and use any service located in this network. It works as VPN service, but all your usual traffic will go trough your provider, not through Yggdrasil Network.

-Also, it is not a goal of the Yggdrasil project to provide anonymity. Direct peers over the Internet will be able to see your IP address and may be able to use this information to determine your location or identity. Multicast-discovered peerings on the same network will typically expose your device MAC address. Other nodes on the network may be able to discern some information about which nodes you are peered with.
-
-All traffic sent across the Yggdrasil network is encrypted end-to-end. Assuming that our crypto is solid, it cannot be decrypted or read by any intermediate nodes, and can only be decrypted by the recipient for which it was intended. However, please note that Yggdrasil has not been officially externally audited.

-Расчетная стоимость представляет собой среднее значение RTT соединения, но новые соединения изначально оцениваются выше, так что можно избежать проблем с нестабильными узлами
-Стоимость соединения используется только при наличии нескольких следующих переходов и будет игнорироваться, если есть только один путь без петель к месту назначения

-Yggdrasil это рабочая реализация полностью зашифрованной сети IPv6.
-Она лёгкая, само-организующаяся, поддерживающая множество платформ, и позволяющая любому ПО, способному работать с IPv6, свободно коммуницировать с другими узлами сети Yggdrasil.
-Yggdrasil не требует Интернет-подключения по IPv6 - она работает и поверх IPv4.
-
-Это приложение позволяет вам подключиться к Yggdrasil Network и пользоваться любыми сервисами, расположенными в этой сети. Оно работает как сервис VPN, но весь ваш обычный Интернет-трафик будет идти через вашего провайдера, не через сеть Yggdrasil.
-
-Заметьте, что анонимность не является целью Yggdrasil. Прямые пиры через Интернет смогут видеть ваш настоящий адрес IP и смогут использовать эту информацию для определения вашего местоположения или идентификации. Пиры, подключающиеся с помощью multicast, скорее всего смогут узнать ваш MAC-адрес. Некоторые узлы в сети могут вычислить через какие узлы вы входите в сеть Yggdrasil.
-
-Весь трафик, пересылаемый через сеть Yggdrasil зашифрован от точки к точке. Предполагая, что наше шифрование  реализовано правильно, трафик не может быть расшифрован или прочитан промежуточными узлами, иможет быть расшифрован только адресатом. Однако, просим заметить, что Yggdrasil не подвергался официальному внешнему аудиту.
