🛑 Breaking changes 🛑

• all: Added support for go1.24, bumped minimum version to 1.23 (#​12370)
• mdatagen: Removing deprecated generated funcs and a few test funcs as well. (#​12304)
• service: Align component logger attributes with those defined in RFC (#​12217)
  See Pipeline Component Telemetry RFC

💡 Enhancements 💡

• otlpreceiver: Update stability for logs (#​12335)
• exporterhelper: Implement sync disabled queue used when batching is enabled. (#​12245)
• exporterhelper: Enable the new pull-based batcher in exporterhelper (#​12291)
• exporterhelper: Update queue size after the element is done exported (#​12399)
  After this change the active queue size will include elements in the process of being exported.
• otelcol: Add featuregate command to display information about available features (#​11998)
  The featuregate command allows users to view detailed information about feature gates
  including their status, stage, and description.

🧰 Bug fixes 🧰

• memorylimiter: Logger no longer attributes to single signal, pipeline, or component. (#​12217)
• otlpreceiver: Logger no longer attributes to random signal when receiving multiple signals. (#​12217)
• exporterhelper: Fix undefined behavior access to request after send to next component. This causes random memory access. (#​12281)
• exporterhelper: Fix default batcher to correctly call all done callbacks exactly once (#​12247)
• otlpreceiver: Fix OTLP http receiver to correctly set Retry-After (#​12367)
• otlphttpexporter: Fix parsing logic for Retry-After in OTLP http protocol. (#​12366)
  The value of Retry-After field can be either an HTTP-date or delay-seconds and the current logic only parsed delay-seconds.
• cmd/builder: Ensure unique aliases for modules with same suffix (#​12201)

🛑 Breaking changes 🛑

• exporterhelper: Rename exporter span signal specific attributes (e.g. "sent_spans" / "send_failed_span") to "items.sent" / "items.failed". (#​12165)

• cmd/mdatagen: Remove dead field telemetry::level (#​12144)

• exporterhelper: Change exporter ID to be a Span level attribute instead on each event. (#​12164)
  This does not have an impact on the level of information emitted, but on the structure of the Span.

• cmd/mdatagen: Remove level field from metrics definition (#​12145)
  This mechanism will be added back once a new views mechanism is implemented.

• service: Value for telemetry exporter otlp.protocol updated from grpc/protobuf to grpc. (#​12337)

• service: internal metrics exported over Prometheus may differ from previous versions. (#​11611)

  Users who do not customize the Prometheus reader should not be impacted. The change to update the internal telemetry to use otel-go config can cause unexpected behaviour
  for end users. This change is caused by the default values in config being different from what the Collector has used in previous versions. The
  following changes can occur when users configure their service::telemetry::metrics::readers:

  • the metric name will append a _total suffix if without_type_suffix is not configured. Set without_type_suffix to true to disable this.
  • units will be appended to metric name if without_units is not configured. Set without_units to true to disable this.
  • a target_info metric will be emitted if without_scope_info is not configured. Set without_scope_info to true to disable this.

💡 Enhancements 💡

• configtls: Allow users to mention their preferred curve types for ECDHE handshake (#​12174)
• service: remove custom code and instead use config package to instantiate meter provider. (#​11611)
• otelcol: Adds support for listing config providers in components command's output (#​11570)
• general: Reduce memory allocations when loading configuration and parsing component names (#​11964)

🧰 Bug fixes 🧰

• exporterhelper: Fix bug that the exporter with new batcher may have been marked as non mutation. (#​12239)
  Only affects users that manually turned on exporter.UsePullingBasedExporterQueueBatcher featuregate.

• service: Preserve URL normalization logic that was present before. (#​12254)

• confighttp: confighttp.ToServer now sets ErrorLog with a default logger backed by Zap (#​11820)

  This change ensures that the http.Server's ErrorLog is correctly set using Zap's logger at the error level, addressing the issue of error logs being printed using a different logger.

• exporterhelper: Fix context propagation for DisabledBatcher (#​12231)

• mdatagen: apply fieldalignment to generated code (#​12125)

• mdatagen: Fix bug where Histograms were marked as not supporting temporal aggregation (#​12168)

• exporterhelper: Fix MergeSplit issue that ignores the initial message size. (#​12257)

• service: Include validation errors from telemetry.Config when validating the service config (#​12100)
  Previously validation errors were only printed to the console

• service-telemetry: pass the missing async error channel into service telemetry settings (#​11417)

💡 Enhancements 💡

• exporterhelper: Add blocking option to control queue behavior when full (#​12090)
• debugexporter: Add EventName to debug exporter for Logs. EventName was added as top-level field in the LogRecord from 1.5.0 of proto definition. (#​11966)
• confighttp: Added support for configuring compression levels. (#​10467)
  A new configuration option called CompressionParams has been added to confighttp. | This allows users to configure the compression levels for the confighttp client.
• exporterhelper: Change the memory queue implementation to not pre-allocate capacity objects. (#​12070)
  This change improves memory usage of the collector under low utilization and is a prerequisite for supporting different other size limitations (number of items, bytes).

🧰 Bug fixes 🧰

• mdatagen: apply fieldalignment to generated code (#​12121)
• otelcoltest: Set DefaultScheme to env in the test ConfigProvider to replicate the default provider used by the Collector. (#​12066)
