March 2026 highlights: Delivered a critical bug fix in elastic/elastic-agent for protected file permission handling. Implemented logic to gracefully handle permission errors during the fix-permissions process, preventing failures when files are protected and ensuring the agent continues to operate. This improves robustness, reliability, and uptime of the permission management workflow in the agent.

February 2026 highlights for elastic/elastic-agent focused on governance, security, and maintainability. Key features delivered include: 1) PII Handling Documentation to clarify where PII can appear, how to limit exposure, and redaction methods, improving data privacy compliance. 2) Privilege Level Change Mechanism with Deduplication to ensure privilege actions run only when necessary, reducing privilege changes and surface area for misconfigurations. 3) Removal of Agentless backstage definitions to simplify configuration and streamline future focus. These changes are supported by targeted commits and align with the roadmap to enhance security and maintainability.

During January 2026, focused on stabilizing and expanding visibility for the elastic-agent run-time, with three key deliverables across the repository. Upgraded core dependencies for improved stability and performance, enhanced on-windows usability, and introduced on-demand container profiling to improve observability without impacting baseline performance. These changes collectively reduce friction for users, improve monitoring fidelity, and set the foundation for further performance optimizations and easier maintainability.

December 2025 monthly summary highlighting key accomplishments, features delivered, major fixes, and business impact across fleet-server and elastic-agent. The month focused on reliability, configurability, and test coverage to support safer upgrades, more flexible fleet configuration, and operational resilience.

Monthly summary for 2025-11 focused on security, reliability, and migration resilience in the elastic-agent repository. Delivered three primary updates that enhance deployment stability, error handling, and backup reliability across Elastic Agent deployments.

Monthly work summary for 2025-10 focusing on Elastic Agent; container migration safety guard implemented to prevent migrations in container environments and to signal unsupported scenarios via ErrContainerNotSupported.

September 2025: Delivered security, reliability, and API robustness improvements across fleet-server, Kibana Fleet, and Elastic Agent. Implemented secure handling of secrets in action data, corrected a fleet feature flag routing issue, updated API migration schemas for compatibility, preserved enrollment tokens and agent IDs during migrations, and enhanced migration orchestration by forwarding migrate actions to components. These changes reduce security risk, improve data integrity, ensure correct feature rollout, and strengthen agent lifecycle management—driving stability and business value for fleet operations.

2025-08 Monthly Summary: Focused on strengthening agent migration flows, improving enrollment reliability, and aligning internal semantics across fleet-server and elastic-agent to boost stability and maintainability. Delivered migration tracking and state management in fleet-server, including MIGRATED unenrollment reason and MIGRATE action handling, with API validation and tests updated. Aligned unenroll reason semantics across components. Hardened migrate action with refined tamper protection evaluation and safer ID persistence, preventing unintended deletions. Improved enrollment reliability by ensuring enrollment URLs include a protocol. These changes reduce migration risk, improve data integrity, and provide a stronger foundation for onboarding/offboarding and automation.

July 2025 monthly summary focusing on key accomplishments across Elastic Agent, Fleet Server, and Kibana agent actions. Delivered secure, scalable enhancements with emphasis on migration workflows, service reliability, privileged access control, and platform-specific packaging improvements.
