Release v1.31.0/v0.53.0/v0.7.0/v0.0.10

Overview

Added

• Add go.opentelemetry.io/otel/sdk/metric/exemplar package which includes Exemplar, Filter, TraceBasedFilter, AlwaysOnFilter, HistogramReservoir, FixedSizeReservoir, Reservoir, Value and ValueType types. These will be used for configuring the exemplar reservoir for the metrics sdk. (#5747, #5862)
• Add WithExportBufferSize option to log batch processor.(#5877)

Changed

• Enable exemplars by default in go.opentelemetry.io/otel/sdk/metric. Exemplars can be disabled by setting OTEL_METRICS_EXEMPLAR_FILTER=always_off (#5778)
• Logger.Enabled in go.opentelemetry.io/otel/log now accepts a newly introduced EnabledParameters type instead of Record. (#5791)
• FilterProcessor.Enabled in go.opentelemetry.io/otel/sdk/log/internal/x now accepts EnabledParameters instead of Record. (#5791)
• The Record type in go.opentelemetry.io/otel/log is no longer comparable. (#5847)
• Performance improvements for the trace SDK SetAttributes method in Span. (#5864)
• Reduce memory allocations for the Event and Link lists in Span. (#5858)
• Performance improvements for the trace SDK AddEvent, AddLink, RecordError and End methods in Span. (#5874)

Deprecated

• Deprecate all examples under go.opentelemetry.io/otel/example as they are moved to Contrib repository. (#5854)

Fixed

• The race condition for multiple FixedSize exemplar reservoirs identified in #5814 is resolved. (#5819)
• Fix log records duplication in case of heterogeneous resource attributes by correctly mapping each log record to it's resource and scope. (#5803)
• Fix timer channel drain to avoid hanging on Go 1.23. (#5868)
• Fix delegation for global meter providers, and panic when calling otel.SetMeterProvider. (#5827)
• Change the reflect.TypeOf to use a nil pointer to not allocate on the heap unless necessary. (#5827)
