- Breaking API changes include updated Marshal signatures, removal of many tracer translator functions and OpenCensus constants, rename of IDFromString, and internalization of packages and enums; some translations are now deprecated.
- Added consumerhelper, shared component support, configurable Prometheus remote‑write queue, and use of ComponentID for obsreport receivers/scrapers, expanding exporter and processor capabilities.
- Fixed multiple bugs: Prometheus receiver metric start time logic, exporter counter suffix handling, batch processor reorder/performance, grpc OTLP exporter allocation, and validation of remote‑write queue settings.
