Sep 1, 2025September 2025: Delivered Linux cgroups CPU constraints integration for oneTBB (uxlfoundation/oneTBB). This feature constrains default concurrency calculations using CPU quotas and periods to align thread management with allocated CPU resources in containerized deployments. The work is captured in commit aea8ce893c8ec758db604292edd3c031f513c057 with description 'Support CPU resource constraints set using cgroups (#1777)'. This release improves resource isolation, predictability, and efficiency for multi-tenant workloads, enabling safer scaling of workloads on shared hosts.
