AWS opensearch-service: OpenSearch release notes describe Dashboards 3.5 security patch
Summary
Rewrites two release-note entries to state that consolidated OpenSearch Dashboards 3.5 is a security patch that upgrades Dashboards while keeping the domain version unchanged, is backward compatible with older OpenSearch versions, and requires service software R20260428/R20260626 or later.
Security assessment
The rewritten notes explicitly and repeatedly describe a 'security patch' that delivers 'all the necessary security updates for OpenSearch Dashboards' to domains running versions 1.3 through 3.5, i.e., a vendor-issued fix addressing vulnerabilities in the Dashboards front end. No CVE or advisory identifier is referenced in the diff, and the remediation is applied automatically via service software updates.
