March 2026 monthly summary for rancher/stackstate-product-docs focusing on delivering an AI Assistant experience and strengthening MCP security, with targeted bug fixes and comprehensive documentation. The AI Assistant now ships with a user-facing UI, MCP-based tool integrations, and cloud-provider backends (AWS Bedrock and Anthropic), accompanied by usage guidance, cost transparency, and visuals. MCP authentication is hardened with service tokens, token requirements, and standardized headers. Reliability improvements were achieved through targeted fixes to UI/workflow flows. Documentation was expanded to cover Anthropic API Key usage as an alternative to Bedrock. These efforts deliver measurable business value by accelerating AI-enabled workflows, reducing security risk, and improving onboarding and cost visibility.

In Sep 2025, delivered a focused feature improvement in StackVista/stackstate-docs to clarify Elasticsearch Snapshot Restore prerequisites and warnings, strengthening data safety in restore workflows. The change documents that existing Elasticsearch indices must be deleted before restoring a snapshot; restoration will fail if prerequisites are not met, and explicit data-loss warnings are shown before indices are recreated from the snapshot. Updated Kubernetes backup documentation to reflect the new restore workflow. This work reduces the risk of unintended data loss and improves disaster-recovery readiness for customers. Key commits include c5bb54c30a423ea43eb424085d504840613530dc (STAC-23332) and a7723b28e985672fd481577acdcc76048ae5a323 (docs update).

Monthly summary for 2025-04 (StackVista/stackstate-docs): Key features delivered include RBAC Security Hardening and Analytics/Metrics UI Documentation Updates. RBAC Security Hardening involved removing execute-scripts and access-analytics permissions from roles, plus documenting the process to disable SecurityContext for ClickHouse on OpenShift with Helm upgrade steps to ensure runAsUser is null for sidecars. Analytics and Metrics UI Documentation Updates involved documenting how to enable Analytics in the SUSE Observability self-hosted product, including permissions and deprecation guidance, and updating MetricBinding layouts to reflect new field names and sorting logic. Major bugs fixed: no critical defects reported this month; security hardening addresses potential misconfigurations and reduces risk. Overall impact and accomplishments: strengthened security posture for the self-hosted stack, clearer deployment and upgrade guidance, and improved onboarding documentation for customers deploying Analytics. Technologies/skills demonstrated: RBAC configuration and OpenShift SecurityContext management, Helm upgrade workflows, and professional technical writing/product documentation for analytics features and data models.
