During November 2024, hr567 enhanced the XTLS/Xray-core repository by implementing a heartbeatPeriod configuration for the WebSocket transport layer, enabling periodic heartbeat messages to improve connection stability and facilitate early detection of dead connections. This feature required careful protocol implementation and network programming in Go, ensuring both client and server support. To complement the code changes, hr567 updated XTLS/Xray-docs-next with clear documentation in Markdown, detailing the new configuration’s purpose and usage. The work demonstrated a thorough approach to configuration management and cross-repository consistency, addressing reliability concerns for WebSocket connections and providing maintainers with actionable, user-facing documentation.
