Changelog

vNext

0.33.0

Released 2026-Sep-18

• Bug fix: Keep OTLP logs with the same target but different scope versions, attributes, or schema URLs in separate groups. Target still overrides the scope name. Export each scope's schema URL instead of the resource's schema URL.

• Bug fix: Accept empty AnyValue objects in OTLP/JSON payloads instead of rejecting the entire request.

• Bug fix: Accept omitted resource fields in empty OTLP/JSON collector requests.

• Bug fix: Accept null fields in OTLP/JSON AnyValue objects as unset.

• Bug fix: Accept OTLP/JSON partial-success responses when protobuf default fields are omitted.

• Performance: group_spans_by_resource_and_scope no longer clones every SpanData. The batch is owned by the function, so spans are now moved into the proto conversion instead of being grouped by reference and cloned. This cuts the transform time of a 512-span batch roughly in half. (#3652)

0.32.0

Released 2026-May-08

• Update proto definitions to v1.10.0.
• Updated schemars dependency to version 1.0.0.
