March 2025 monthly summary for open-telemetry/semantic-conventions focused on delivering the CPU Metrics Namespace Consolidation. Implemented migration of CPU-related system metrics to a dedicated 'cpu' namespace and deprecated system.cpu.* to improve organization and clarity of metrics. No major bugs reported this month. This change lays groundwork for consistent metric naming across exporters and dashboards, enabling clearer instrumentation and easier onboarding for contributors. Key commit driving this work: bdb26d929b45e73222b7a3602f56f439b1ee8ebf (refactor: move system cpu-related metrics to cpu namespace, #1896).

February 2025 Monthly Summary: Delivered security-conscious container runtimes, scalable deployment configurations, and robust OTLP ingestion improvements across two repositories, with a focus on reliability, maintainability, and business value.
