The concurrency limit for Logs Insights queries per account increased from 30 to 100, allowing more users to run queries and dashboards simultaneously. API limits for StartQuery and GetQueryResults increased to 10 calls per second per region per account.

These enhancements improve query throughput and reduce throttling, benefiting large-scale monitoring and log analysis workloads. Availability spans many global AWS regions, though user experience and performance impact depend on individual workloads and infrastructure.
