- Breaking rename of CustomUnmarshable to Unmarshallable and change default OTLP/HTTP port from 55681 to 4318
- Added new data model capabilities: Bytes attribute type, SchemaUrl field, and attributes on NumberDataPoint/HistogramDataPoint/SummaryDataPoint, plus OTLP proto v0.9.0 update and refreshed conventions
- Fixed bugs in gRPC server interceptors, Prometheus receiver interval handling, and Jaeger translator, but note the release is marked as bad due to metrics pipeline issues
