End User Changelog

🛑 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.

💡 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 temporaly 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)
