🛑 Breaking changes 🛑

• exporter/otlp: Remove deprecated batcher config from OTLP, use queuebatch (#13339)

💡 Enhancements 💡

• exporterhelper: Enable items and bytes sizers for persistent queue (#12881)
• exporterhelper: Refactor persistent storage size backup to always record it. (#12890)
• exporterhelper: Add support to configure a different Sizer for the batcher than the queue (#13313)
• yaml: Replaced sigs.k8s.io/yaml with go.yaml.in/yaml for improved support and long-term maintainability. (#13308)

🧰 Bug fixes 🧰

• exporterhelper: Fix exporter.PersistRequestContext feature gate (#13342)

• exporterhelper: Preserve all metrics metadata when batch splitting. (#13236) Previously, when large batches of metrics were processed, the splitting logic in metric_batch.go could cause the name field of some metrics to disappear. This fix ensures that all metric fields are properly preserved when metricRequest objects are split.

• service: Default internal metrics config now enables otel_scope_ labels (#12939, [#13344]) By default, the Collector exports its internal metrics using a Prometheus exporter from the opentelemetry-go repository. With this change, the Collector no longer sets "without_scope_info" to true in its configuration.

This means that all exported metrics will have otel_scope_name, otel_scope_schema_url, and otel_scope_version labels corresponding to the instrumentation scope metadata for that metric.

This notably prevents an error when multiple metrics are only distinguished by their instrumentation scopes and end up aliased during export.

If this is not desired behavior, a Prometheus exporter can be explicitly configured with this option enabled.
