October 2025 (Month: 2025-10) monthly summary for wazuh/wazuh: focus on reliability, observability, and workflow robustness. Delivered two critical bug fixes improving build agent reliability and log quality, with CI/workflow improvements that reduce toil and false alarms. These changes improved CI stability, reduced log noise, and enhanced cross-platform packaging and journald detection.

September 2025: Deprecation of HP-UX support across agent and build system, stabilization of AIX packaging, and CI/build reliability improvements. These changes reduce maintenance overhead, minimize platform-specific risk, and improve build stability and delivery velocity.

Monthly summary for 2025-08 focusing on key features delivered, major bug fixes, business impact, and technical achievements across wazuh/wazuh and wazuh/qa-integration-framework.

July 2025 Monthly Summary for wazuh/wazuh Key features delivered: - Graceful configuration reload via new 'reload' command for Wazuh agent and manager, enabling reloads without full restarts (commit 2fb05aa...). Improves operational flexibility and reduces downtime during config changes. - Packaging metadata standardization across RPM and Debian to 'Wazuh, Inc.' including the period for agent and manager components (commit cd10fb4819...). Ensures branding consistency and easier compliance checks. - Windows test suite compatibility improvement by conditionally compiling winagent buffer tests to avoid Windows-specific compilation errors, increasing cross-OS test reliability (commit 68a06c5d...). - Robust installation script with improved error handling, extensive journalctl checks, cleanup of executables before reinstallation, and immediate exit on failure (commits d3033fe63d..., a21a413d1a...). - Test artifacts cleanup in installation-related script by removing lines that delete test executables/binaries, streamlining the install process (commit 1da7d61a7aa...). Major bugs fixed: - OpenSCAP integration removal: deprecated and removed the OpenSCAP module and its configuration, along with related code, tests, and language templates to simplify the product and align with current strategy (commits 04906a57..., d961ad53..., 25b07e83...). - General stabilization of test suites across targets via Windows compatibility updates and artifact cleanup. Overall impact and accomplishments: - Enhanced deployment reliability and runtime operability across platforms, enabling safer config reloads, streamlined installations, and reduced maintenance burden through standardization and deprecation of outdated components. These changes support faster time-to-value for operators and a clearer strategic direction for the product. Technologies/skills demonstrated: - Release engineering and build/test hygiene (CI, packaging, test silos) - Cross-platform test strategy and conditional compilation for Windows - Shell scripting robustness (robust error handling, logging) and artifact management - Branding/packaging standardization and deprecation planning

Concise monthly summary for 2025-05 focusing on key bug fixes and stability improvements for wazuh/wazuh. Delivered two critical fixes that strengthen deployment reliability and data integrity.

April 2025 (2025-04) – wazuh/wazuh: Focused on reliability improvements for service lifecycle by optimizing startup and shutdown timings. Implemented startup/shutdown timing optimization: increased wazuh-agent and wazuh-manager startup timeouts to 45 seconds and shortened the force-stop duration by reducing maximum kill attempts from 600 to 300, achieving an approximate 30-second force-stop. This change enhances startup reliability, reduces shutdown latency, and lowers deployment risk. Commit reference: 035642c38f16cffd6260b902b786cd2bbadd0982.

March 2025 performance and delivery summary for wazuh/wazuh. Delivered packaging enablement for the Wazuh agent with packaging updates and a refined eBPF filtering path to cut unnecessary event processing, resulting in leaner agent operation and lower resource usage. Implemented Linux-only eBPF build to prevent cross-platform build/runtime issues, improving build stability and reducing platform-specific failures. Strengthened the eBPF capability with enhanced error handling, a new testing framework, and multiple unit tests verifying eBPF availability and whodata processing; these changes included refactors and infrastructure improvements, including smartpointer usage for ebpf_helper and related modules. This work lays a foundation for robust, observable eBPF behavior in production, with increased test coverage and maintainability.

February 2025 monthly summary focusing on eBPF deployment improvements in wazuh/wazuh. Delivered dynamic libbpf loading to enable flexible eBPF usage and updated installation dependencies to support the new loading mechanism, improving setup and deployment of eBPF in the Wazuh agent. This reduces static dependencies and enhances runtime flexibility for eBPF features.

January 2025 — Delivered self-restart capability for wazuh-agent to improve resilience and uptime. Implemented restart via systemd or by forking a new process, added tests, and laid out Unix-specific logic with a Windows placeholder, plus a stop timeout. Documentation updated for the restart command and agent lifecycle.

December 2024: Delivered a critical uninstall data-persistence fix for wazuh-agent, preserving agent data and configurations across uninstall/reinstall, and reducing potential data loss and support tickets. Commit d69891cef328eb3d055de432f0a3cbac79b446d6.

November 2024 monthly summary: Focused on strengthening Windows data collection, packaging reliability, and Debian packaging hygiene across wazuh/wazuh and wazuh/wazuh-agent. Key investments centered on Windows hotfix inventory through WMI and Windows Update Agent APIs, CI/packaging improvements for Windows builds (including Wine packaging), and packaging maintainability in the agent with Debian-specific refinements. These efforts improved visibility into Windows hotfix coverage, reduced build-time issues, and streamlined deployment workflows for on-prem and cloud tenants.
