Key Changes

LitmusChaos 3.29.0, a minor update released on 2026-05-18, focuses on enhancing observability, security, and overall stability for chaos engineering workflows.

New Features:

  • Prometheus Metrics Integration: This release introduces new Prometheus metrics, providing deeper insights into chaos experiments and system behavior. A dedicated getting started guide is also available to help users configure and utilize these metrics effectively.

Security & Stability Fixes:

  • gRPC Dependency Update: A critical security fix bumps google.golang.org/grpc to v1.79.3, addressing CVE-2026-33186 and bolstering the tool’s security posture.
  • Experiment Trigger Prevention: The event-tracker now prevents duplicate chaos experiment triggers under concurrent reconciles, ensuring more reliable experiment execution.
  • Improved Experiment Control: Users can now stop experiments even when the underlying infrastructure is disconnected, enhancing operational control and recovery capabilities.
  • UI/UX Enhancements: Several user interface issues have been resolved, including a blank page for CronWorkflow run history and improved navigation refresh logic when projectID or scope changes. Documentation typos and outdated links were also corrected.

Impact for QA Teams

For QA engineers, LitmusChaos 3.29.0 brings significant improvements. The new Prometheus metrics offer enhanced visibility into system resilience during chaos experiments, aiding in more precise validation of failure scenarios. Increased stability, particularly the fix for duplicate experiment triggers and the ability to stop experiments reliably, means more consistent and trustworthy test results. The security update also ensures a safer testing environment.
