January 2026 monthly summary for reactos/reactos focusing on audio subsystem UX improvements and reliability across virtualization and external control scenarios.

November 2025 (86Box/86Box) focused on improving cross-platform stability for ATI graphics emulation. Delivered a targeted fix to prevent startup crash (exit code 11) when an ATI graphics adapter is used on non-Windows platforms, improving reliability for Linux/macOS and other non-Windows environments. This work stems from a low-level NVRAM initialization adjustment on the MCA bus variant for ATI (commit 138929caec75ecd0ee528b87639fedf178cd9c1c).

July 2025: Delivered SEH2 macro compatibility fix for Linux x64 GCC/Clang builds in reactos/reactos. Guarded SEH2 macros with #ifndef __try to avoid conflicts with GCC's x64 Linux STL and STLport-related issues (affecting wlanwiz). Result: smoother CI builds, fewer regressions across Linux x64 builders and improved macro reliability.

June 2025 monthly summary for reactos/reactos focused on expanding Wi-Fi security support by updating the PSDK DOT11_AUTH_ALGORITHM enumeration. Key feature delivered: WPA3 support with new algorithm values (WPA3, WPA3-SAE, WPA3-ENT), plus conditional WPA3-ENT_192 and OWE gating based on Windows version to maintain backward compatibility while aligning with modern security standards. This work is implemented in a single cored feature under the commit 26368a1eadbd759621a37760a639d0c88bdec274, titled "[PSDK] Enumerate WPA3 algorithms in `DOT11_AUTH_ALGORITHM` (#8129).

January 2025 monthly summary focused on strengthening WLAN API capabilities and improving cross-compiler build stability for ReactOS. Key work delivered includes new WLAN radio state data structures and enumeration for WlanQueryInterface, along with native data access permission flags to govern read/write/execute access to WLAN data via API functions. A dedicated build fix addressed i386 compile failures when using x64 clang-cl by applying -m32 in CMAKE_C_FLAGS and CMAKE_CXX_FLAGS under USE_CLANG_CL (excluding ARM64), ensuring reliable operation in the x86 Native Tools environment. These changes reduce security and data-access risks while expanding cross-platform support and maintainability. Impact and value: Enables safer, more controlled WLAN data exposure through the API, improves build stability for a wider range of targets, and accelerates downstream development and testing cycles. Technologies/skills demonstrated: CMake, clang-cl cross-compilation, Windows WLAN API design, data-structure/enumeration design, cross-architecture compatibility, and disciplined commit-based change management.

December 2024 monthly summary for reactos/reactos focusing on targeted codebase standardization and bug resolution. The primary effort this month was aligning SDK naming conventions for Network Connections (CLSID) across multiple modules to reflect public Windows SDK naming (CLSID_NetworkConnections). This work enhances consistency, reduces cross-module maintenance complexity, and improves future SDK compatibility.

2024-11 monthly summary focusing on key accomplishments, business value, and technical achievements for reactos/reactos. Key features delivered: - Wi-Fi API: WLAN_AVAILABLE_NETWORK.dwFlags definitions added to wlanapi.h to expose detailed Wi-Fi access point states (connection status, profile availability), aligning with Windows 10 SDK updates to improve Wi-Fi network management capabilities. Major bugs fixed: - None reported this month related to WLAN; no major bug fixes recorded for this period. Overall impact and accomplishments: - Aligns ReactOS with Windows SDK expectations, enabling more accurate Wi-Fi state reporting and smoother integration with Windows-based networks. - Lays groundwork for improved Wi-Fi configuration flows and troubleshooting, reducing feature gaps for network management. Technologies/skills demonstrated: - C/C++ code changes in the ReactOS WLAN API surface - Adherence to Windows SDK alignment and ABI compatibility - Patch contribution and commit traceability with reference to (#7504) and commit 2e3a080e108f58e47385e463babb3e31a29d40af Repository: reactos/reactos
