During November 2024, hr567 enhanced the XTLS/Xray-core repository by implementing a heartbeatPeriod configuration for the WebSocket transport layer, using Go to enable periodic heartbeat messages between client and server. This addition improved connection stability and allowed for early detection of dead connections, addressing reliability concerns in network programming. To ensure users could effectively leverage this feature, hr567 also updated the XTLS/Xray-docs-next repository, providing clear Markdown documentation on configuring the new heartbeatPeriod option. The work demonstrated depth in protocol implementation and configuration management, with careful alignment between code and documentation to maintain consistency across both repositories.
