July 2025 monthly summary for wazuh/wazuh focusing on delivering features, stabilizing builds across platforms, and advancing SCA integration. Key feature work includes integrating the file_helper submodule with updated CMake, enabling unit tests, and cleaning up subdirectory inclusions; additional progress on linking FilesystemWrapper; and SCA startup/configuration improvements, including installation-time library handling. Testing and infrastructure improvements reduced build/test friction and improved observability during startup. These efforts deliver tangible business value through safer deployments, faster validation, and stronger cross-platform support.

June 2025 monthly work summary for wazuh/wazuh: Focused on stabilizing the Windows agent FlatBuffers build by restructuring how the flatc compiler is built and used, using ExternalProject to host a build tool, enabling schema generation without pre-built binaries or system installations, improving cross-environment reliability and maintainability.

May 2025 for wazuh-agent: Delivered observability, reliability, and maintainability improvements that translate to safer operations and faster triage across agent policy checks. Business value delivered includes reduced wasted compute from gating SCA, stronger policy enforcement, and improved incident response through richer diagnostics. Technical highlights include extensive logging for SCA lifecycle and policy evaluation; gating SCA execution when disabled; per-Run IO context reset to prevent state leakage; major architectural refactors with TaskManager integration and API/name parity (e.g., LoadPolicies, CheckResultToString), DirRuleEvaluator improvements, and Run/QueryEvents refactor; PCRE2 pattern matching enhancements; improved filesystem checks and NotFound handling; and expanded unit tests for TaskManager and rule evaluation. These changes collectively decrease runtime overhead, improve reliability, and accelerate issue diagnosis and onboarding.

April 2025 monthly summary focuses on building a scalable, testable, and cross-platform policy evaluation framework across wazuh-agent and wazuh. Key features delivered included foundational SCAPolicyLoader infrastructure that enables policy loading via a pluggable loader and optional filesystem wrapper, plus tests validating policy retrieval. Groundwork was laid for SCA configuration parsing with default configuration scaffolding, enabling more robust configuration testing. A major architectural shift introduced modular, multi-instance capable components, with IModule interfaces and a refactored PushMessage system, setting the stage for easier testing and deployment at scale. The evaluator framework was expanded with RuleEvaluator and supporting components (CheckConditionEvaluator, PatternMatches, and content/file rule evaluators), and subsequent Run/Stop control flow improvements for policy evaluation. Additional work covered extensive bug fixes, documentation updates, and platform/tooling enhancements to improve reliability and performance, including cross-platform OsUtils, dynamic PID retrieval, YAML loading centralization, and platform-specific logic separation.

March 2025 monthly highlights across wazuh-agent, wazuh, and qa-integration-framework. The team delivered a robust set of documentation, packaging, CI, and SCA platform improvements, underpinned by strong testing and cross-language tooling. Improvements span documentation quality, packaging reliability, SCA API modernization, and cross-repo versioning consistency, driving faster release cycles and safer deployments.

February 2025 (2025-02) focused on strengthening configuration defaults, improving testability, and reinforcing cross‑platform reliability in wazuh-agent. Delivered centralized GetConfigOrDefault usage across ConfigurationParser and related modules to ensure consistent default handling, reducing configuration drift. Implemented in-range defaults and parsing methods for time/value ranges with accompanying tests, and added default range validation for time settings. Reorganized agent lifecycle by consolidating enrollment workflows under AgentRunner and completing lifecycle orchestration (RegisterAgent/StatusAgent/StartAgent) in a single flow, while modernizing naming to Enrollment. Standardized versioning and packaging through VERSION.json integration across workflows and install paths, enabling consistent builds and releases. Initiated CI/CI hygiene improvements (removing unused Actions) and platform-specific fixes to Windows, along with broader code quality improvements (const correctness, chrono types, structure bindings) to improve maintainability, portability, and performance.

January 2025 monthly summary for wazuh-agent focused on delivering cross-platform Apple OS log ingestion capabilities, strengthening reliability through tests, and modernizing the build and packaging stack to improve reproducibility and CI efficiency. Key outcomes include a new OS Log Reading Framework with OSLogStoreWrapper, ULSReader, and platform-specific readers; expanded unit tests and mocks for ULSReader/macOS readers; and a set of architecture and build improvements that reduce dependencies and improve maintainability.

December 2024 was characterized by architectural refinements, stability improvements, and enhanced observability in wazuh-agent. Key progress includes centralizing and hardening timeout handling by moving it to HttpClient, enforcing safe batching through upper limits on batch interval and size, and replacing the refresh interval magic number with a named constant. Batching behavior is further clarified by centralizing max batch size usage in the Communicator. A series of TaskManager and ModuleManager improvements established clearer ownership, improved startup/shutdown sequencing, and stronger thread-safety controls, including enforcing a minimum thread count at init and moving the TaskManager to its own build target. Logging and traceability were enhanced by adding a taskID to EnqueueTask methods and attaching task names to EnqueueTask calls, aiding debugging and operational visibility. Additional reliability improvements include catching exceptions in Agent execution, enhanced HTTP error reporting, and improved resource cleanup during failures. Broad test coverage enhancements were delivered via parameterized HTTP status tests and test refactors, and several stabilization fixes in tests and shutdown order. Combined, these changes reduce runtime errors, improve throughput, and make wazuh-agent more maintainable and observable in production.

November 2024 performance summary: Delivered core feature integrations, reliability hardening, and scalable configurations across wazuh-agent and wazuh. Key business value includes improved data persistence reliability, safer startup defaults, configurable batching and thread pools, stronger error handling, and enhanced security posture through JWT/mocking improvements.
