February 2026 monthly summary for wazuh/wazuh: Delivered two major features across agent data handling and cross-module synchronization, resulting in improved data consistency, reliability, and maintainability. Agent metadata now uses a structured wazuh.agent JSON key with references updated across codebase. Synchronization framework enhancements include refined tracking limits, standardized sync flags, DB sync refactor, removal of deprecated methods, improved orphaned-delete handling, and expanded test coverage and documentation. Together, these changes reduce data drift, enhance cross-module integrity, and set a clearer path for future feature work.

Month: 2026-01 — Focused on strengthening test reliability for FIM file handling in wazuh/wazuh by delivering a targeted test verification refactor that improves determinism and speeds up CI feedback.

December 2025 monthly summary for wazuh/wazuh focusing on data integrity, recovery, and test observability. Delivered multiple features with strong business value: database entry versioning and enhanced data integrity, C-based recovery enhancements with checksum integration, proactive integrity configuration, and enhanced integration test reporting. These deliverables reduce data loss risk, improve recoverability, and provide better visibility into system health and performance.

November 2025 highlights wazuh/wazuh: delivered robust scan initialization and recovery capabilities, strengthened registry scan concurrency, and enhanced observability, while stabilizing the build and CI pipeline. The month focused on enabling reliable first scans, deterministic recovery data handling, and improved incident response through new logging and documentation, supported by memory hygiene before sync and module integrations.

For 2025-10, wazuh/wazuh delivered a precision improvement in File Integrity Monitoring by including file path in the FIM checksum. The fim_file_data data model was extended with a path field and the checksum generation logic updated to incorporate the path, resulting in more accurate integrity verification and stronger audit trails. No major bugs fixed this month. Overall impact includes improved security monitoring reliability, better change detection, and stronger compliance posture. Key technologies demonstrated: data model extension, checksum algorithm integration, and incremental feature delivery with traceable commits.

September 2025 monthly summary for wazuh/wazuh: Focused on strengthening the upgrade experience and stabilizing the build/runtime path across platforms. Delivered Agent Upgrade Process Enhancements and Testing with improved upgrade filtering, extraction/validation of agent configurations, expanded error reporting, and updated test coverage including deprecated option warnings. Completed Legacy Upgrade Cleanup and Build/Runtime Fixes, including removal of legacy databases during upgrades (4.x → 5.x), corrected wazuh-lib runtime rpath in the manager Makefile, and cleanup of SunOS-specific Makefile rules. These efforts reduce upgrade risk, improve stability and maintainability, and demonstrate cross-team collaboration on testing, build systems, and platform support.

August 2025 monthly summary: Delivered significant features and stabilizing fixes across wazuh/wazuh and wazuh/qa-integration-framework, emphasizing business value through reliability, clarity, and safer upgrade paths. Key outcomes include Windows log collector glob improvements, standardized deprecation messaging, WPK upgrade validation/testing enhancements, preservation of NFS skip behavior, and restoration of essential agent management modules. QA improvements corrected authentication path references and aligned tooling with a stable baseline.

For 2025-07, delivered a focused decommissioning and maintenance initiative across wazuh/wazuh and wazuh-documentation, targeting deprecated components, improved test coverage, and cleaned release artifacts. The work reduces risk, simplifies future maintenance, and enhances build/release reliability by removing obsolete features, updating documentation, and tightening CI/packaging processes.
