April 2026: Delivered measurable business value through CI/CD modernization, robust QUIC transport enhancements, security hardening, and flexible datagram parameter handling across two repositories (apernet/hysteria and SagerNet/quic-go). These changes improved deployment reliability, connection performance, security posture, and protocol adaptability under diverse network conditions.

Summary for 2026-03: Delivered key features improving reliability, configurability and CI; refactor header to xForwarded, added configurable congestion modes and BBR profiles, server-side UDP port range listening, and port hopping with random intervals. CI enhancements included updating artifact tool versions and test workflow. Fixed critical bugs including BBR scale window for datagram size, Go test command invocation, dependencies updates, quic-go datagram size panic, and firewall/iptables adjustments. These changes reduce operational risk, improve performance, and enable scalable deployments.

February 2026 (2026-02) — Apernet/hysteria monthly summary. Focused on delivering configurable testing capabilities and stabilizing the development pipeline to boost velocity and reliability. Key outcomes include a new time-based speed test mode, updated CI/CD workflows with dependency upgrades, and targeted code quality improvements that reduce duplication and simplify configuration handling. Business value centers on faster, more flexible testing experiences for users and more maintainable, stable build processes for the team.

January 2026: Quic-go upgrade and congestion interface integration across apernet/hysteria. Upgraded Quic-go to v0.57.2, migrated to the new monotone congestion interface, and updated dependencies across modules to ensure compatibility and leverage latest congestion control improvements. This work improves transport performance under variable networks, reduces risk of congestion-related stalls, and enhances maintainability through a unified congestion interface across the repository.

December 2025 performance summary for apernet/hysteria. Delivered targeted improvements in CI/CD artifact management and critical congestion control reliability, with measurable impact on release velocity and runtime stability.

October 2025: Focused on stability and performance improvements in apernet/hysteria by upgrading a core network dependency to address memory leak and enhance resource management. Completed a cross-module quic-go upgrade, updated module manifests, and validated builds. Emphasized maintainability and scalability by updating go.mod/go.sum and coordinating dependency changes across modules. Commit reference used for the fix: 6e59b176a642625e4641395ef431b14ecbf601ab.

Month: 2025-09 | Apernet/hysteria focused on network reliability, build stability, and maintainability. Key features delivered and issues fixed include: (1) UDP Session Manager Race Condition Fix: resolved a race in the cleanup process, improved error handling and return values across UDP operations, with code formatting updates for maintainability. (2) Quic-go Library Upgrade and Protocol Robustness: upgraded to quic-go v0.54.0 to refine QUIC handling and strengthen network robustness, aligning internal mocks and dependencies. (3) Go Toolchain and Build Environment Updates: updated Go to 1.25.1 across modules and CI workflows to ensure compatibility and forward-compatibility in builds. (4) Code Quality and Maintainability: broader formatting and readability improvements (gofumpt) across the network stack.

June 2025 delivered a stability-focused QUIC path management improvement for apernet/hysteria by updating the QUIC stack to v0.52.1 and enabling a new DisablePathManager option on both client and server. This work, tied to commit b5ddcb5bc49cdee6a2c58084e6afff4063748b3a, reduces path flapping and improves connection resilience in unstable networks. No high-severity bugs were reported; the focus was on feature delivery, reliability, and maintainability. The update enhances business value by improving user experience in variable networks and simplifying network path tuning.
