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.
