End User Changelog

🛑 Breaking changes 🛑

• cmd/opampsupervisor: Remove the reports_package_statuses capability config option. The accepts_packages option now enables both the AcceptsPackages and ReportsPackageStatuses OpAMP capabilities. (#49762) Neither capability was functional; the supervisor exits with an error at startup when configured, so no working configuration is affected.

• processor/drain: Add masking rules for named parameter extraction. Removes the extract_parameters and params_attribute config fields released in v0.157.0. (#48914) Adds masking_rules, an ordered list of {name, pattern} regex substitutions applied to a copy of the log body before it is fed to the Drain tree. Matched substrings become named mask tokens in derived templates (for example <ip>), stabilising the tree on high-cardinality values. Each masked position writes a dynamic attribute at <parameter_key_prefix>.<mask name> (default prefix log.record.template.parameter), matching the OTel semantic-convention pattern used by http.request.header.<key> and db.query.parameter.<key>.

  Adds emit_wildcards (default false): when true, Drain's own <*> positions are written to a positional string slice attribute at wildcards_attribute (default log.record.template.wildcards). Independent of masking_rules, so users can enable it without any rules to see raw variable values before deciding what to mask.

  When a mask name matches multiple positions in the same template, first-match wins and the losing values are dropped. The otelcol_processor_drain_masks_duplicates counter is incremented once per record per duplicated mask name, tagged with a mask attribute for observability.

  Breaking: the positional-only extract_parameters and params_attribute fields released in v0.157.0 are removed. Collectors with either field set will fail to start after upgrading. To migrate, replace extract_parameters: true with emit_wildcards: true, and rename params_attribute to wildcards_attribute. The behaviour is identical; only the field names change. Note the default output attribute also renames from log.record.template.params to log.record.template.wildcards, so downstream consumers of the old attribute key should either update their references or set wildcards_attribute: log.record.template.params to keep the old key.

• processor/dynamic_sampling: Flatten sampler config, rename key_fields to key_attributes, drop initial_sampling_rate. (#49311) Sampler fields no longer live under a per-type sub-block (sampler.<type>.<field>); they move up one level under sampler: with type acting as the discriminator. key_fields is renamed to key_attributes to match OTel attribute vocabulary used elsewhere in the processor. The rarely-used initial_sampling_rate on ema_throughput is removed; dynsampler-go's default applies. goal_throughput_per_sec is now int for both throughput samplers. Fields set for a sampler type that does not use them are rejected at config validation.

• processor/dynamic_sampling: Replace the custom rule condition parser with OTTL expressions and add a match field to control same-span vs any-span semantics. (#49311) Rule conditions: are now OTTL boolean expressions evaluated in the ottlspan context. Path expressions must be qualified with a context prefix (span.attributes["k"], resource.attributes["k"], span.status.code, etc). A new per-rule match: field selects any_span (default, each condition

v0.158.0

🛑 Breaking changes 🛑

• all: Stops embedding all configuration fields (#49797, #49913, #49914, #49915, #49965, #49966, #49972, #49973, #49974)

  • Embedded fields do not work well with tooling and libraries such as mapstructure and should be avoided.

• pkg/ottl: OTTL context path setters now handle nil values based on the path type (#49728)

v0.157.0

🛑 Breaking changes 🛑

• pkg/ottl: Break lambda arity validation into a separate function. (#49421) This allows statically verifying arity.

💡 Enhancements 💡

• internal/k8sinventory: Extract checkpoint package and update Observer interface to return startup errors. (#43602)

  • Extracted internal/k8sinventory/checkpoint as a shared package so checkpoint logic can be reused across observer implementations.
  • The Observer interface's Start method now returns an error, allowing callers to detect and propagate startup failures.

• pkg/ottl: Add LambdaActivation.IsArgBound and variadic lambda argument evaluation helpers. (#49191)

  • IsArgBound reports whether a positional argument maps to a named formal parameter or a blank ("_") placeholder.
  • Lambda evaluation helpers now normalize only bound arguments.

• pkg/pdatatest: Add IncludeHistogramExplicitBounds option to pmetricassert snapshot generation. (#49732) The option includes histogram explicit bounds without including other histogram datapoint values. Snapshot compaction preserves selected histogram datapoint assertion fields, including empty explicit bounds.

v0.156.0

🛑 Breaking changes 🛑

• all: handle breaking change in pdata/pprofile (#49373)
• pkg/ottl: Switch LambdaExpression arguments to be pointers. (#49420) These values are intended to be mutable and are passed by reference in normal use, so this keeps symmetry between the argument declaration and their use by the function.

💡 Enhancements 💡

• pkg/ottl: Add ottl.NewTestingLambdaExpression and internal helpers for implementing lambda-based OTTL functions. (#49180) Adds ottl.NewTestingLambdaExpression, a test helper that builds a LambdaExpression with a custom value body. The callback receives resolveBinding func(string) any to

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (#8511)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/metrics")) to preserve the previous behavior. (#8538)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/traces")) to preserve the previous behavior. (#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.
• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp.

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (#8511)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/metrics")) to preserve the previous behavior. (#8538)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/traces")) to preserve the previous behavior. (#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.
• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8383)
