+Updated core library to 0.5.7, presenting these changes:
+
+Added
+WebSocket support for peerings, by using the new ws:// scheme in Listen and Peers
+Additionally, the wss:// scheme can be used to connect to a WebSocket peer behind a HTTPS reverse proxy
+
+Changed
+On Linux, the TUN adapter now uses vectorised reads/writes where possible, which should reduce the amount of CPU time spent on syscalls and potentially improve throughput
+Link error handling has been improved and various link error messages have been rewritten to be clearer
+Upgrade dependencies
+
+Fixed
+Multiple multicast connections to the same remote machine should now work correctly
+You may get two connections in some cases, one inbound and one outbound, this is known and will not cause problems

+Обновлена основная библиотека до версии 0.5.7, в которой представлены следующие изменения:
+
+Добавлено
+Поддержка WebSocket для пиринга с использованием новой схемы ws:// в Listen и Peers
+Кроме того, схему wss:// можно использовать для подключения к узлам WebSocket за обратным прокси-сервером HTTPS вроде Nginx
+
+Изменено
+В Linux адаптер TUN теперь использует векторизованную чтение/запись, где это возможно, что должно сократить количество времени ЦП, затрачиваемого на системные вызовы, и потенциально повысить пропускную способность
+Улучшена обработка ошибок соединения, а различные сообщения об ошибках соединения были переписаны для большей ясности
+Обновление зависимостей
+
+Исправлено
+Несколько мультикаст подключений к одной и той же удаленной машине теперь должны работать правильно
+В некоторых случаях вы можете получить два подключения, одно входящее и одно исходящее, это известное поведение и не вызовет проблем
