In March 2026, delivered performance and stability enhancements across XTLS/Xray-core and related documentation, focusing on transport efficiency, header customization, QUIC configuration, and network reliability. Key features delivered include MTU-aware mKCP ACK enforcement to improve transmission efficiency and reliability; header-custom with fragmentation and stability improvements for TCP/UDP, along with UDP noise handling and improved stability for XDNS/XICMP; unified QUIC configuration with an upgrade to newer quic-go to boost congestion control and overall stability; RandRange expansion for header-custom and UDP noise masking to improve randomness and noise quality; and WireGuard UDP FullCone NAT support plus inbound multi-peer routing fixes to enhance NAT handling and routing reliability. Documentation updates describe Hysteria protocol and Finalmask integration to help users configure features effectively. These changes collectively improve throughput, reduce latency, and enhance resilience across deployed configurations, delivering tangible business value for clients relying on high-performance, reliable transport and secure tunneling.

February 2026 monthly summary for XTLS/Xray-core. Delivered major transport-layer enhancements and security features with a focus on enabling scalable, low-latency connections across diverse networks. The work included XICMP transport layer support (client/server implementations with IP/ID configuration management), UDP transport security enhancements (WireGuard and Shadowsocks AEAD, with dialer logic updates and UdpmaskManager integration), and Hysteria 2 inbound and transport capabilities (multi-listening port support, Salamander finalmask integration, and expanded user/transport configuration options). These contributions strengthen security, improve performance, and broaden deployment scenarios for client and server implementations across various environments.

January 2026 highlights for XTLS/Xray-core focused on expanding high-performance transport capabilities and reliability. The team delivered a major Hysteria transport integration with UDP-based outbound transport, congestion control options, and obfuscation features, along with improved UDP dialing reliability and QUIC compatibility; introduced a dedicated congestion configuration and enforced Hysteria client version. In parallel, XDNS functionality was added via mKCP, enabling header-configurable, mkcp-supported DNS-related connections and AES128GCM encryption to boost transport performance and security across multiple protocols. Key outcomes include a more robust proxy stack with configurable transport behavior, reduced latency and improved resilience under variable network conditions, and expanded support for secure, low-latency connections across DNS, DTLS, SRTP, UTP, WeChat, and WireGuard.

Monthly summary for 2025-08 (XTLS/Xray-core). Focused on delivering business value through reliability improvements and API quality enhancements in IP-based online user tracking.
