End User Changelog

🛑 Breaking changes 🛑

• confighttp: Move confighttp.framedSnappy feature gate to beta. (#10584)

💡 Enhancements 💡

• exporter/debug: Move to alpha stability except profiles (#13487)

• exporterhelper: Enable exporter.PersistRequestContext feature gate by default. (#13437) Request context is now preserved by default when using persistent queues. Note that Auth extensions context is not propagated through the persistent queue.

• pdata: Use pdatagen to generate marshalJSON without using gogo proto jsonpb. (#13450)

• otlpreceiver: Remove usage of gogo proto which uses reflect.Value.MethodByName. Removes one source of disabling DCE. (#12747)
• exporterhelper: Fix metrics split logic to consider metrics description into the size. (#13418)
• service: New pipeline instrumentation now differentiates internal failures from downstream errors (#13234) With the telemetry.newPipelineTelemetry feature gate enabled, the "received" and "produced" metrics related to a component now distinguish between two types of errors:
• "outcome = failure" indicates that the component returned an internal error;

• "outcome = refused" indicates that the component successfully emitted data, but returned an error coming from a downstream component processing that data.

• pdata: Remove usage of text/template from pdata, improves DCE. (#12747)

• architecture: New Tier 3 platform riscv64 allowing the collector to be built and distributed for this platform. (#13462)

🧰 Bug fixes 🧰

• exporterhelper: Prevents the exporter for being stuck when telemetry data is bigger than batch.max_size (#12893)
• mdatagen: Fix import paths for mdatagen component (#13069)
• otlpreceiver: Error handler correctly fallbacks to content type (#13414)
• pdata/pprofiles: Fix profiles JSON unmarshal logic for originalPayload. The bytes have to be base64 encoded. (#13483)
• xpdata: Fix unmarshaling JSON for entities, add e2e tests to avoid this in the future. (#13480)
• service: Downgrade dependency of prometheus exporter in OTel Go SDK (#13429) This fixes the bug where collector's internal metrics are emitted with an unexpected suffix in their names when users configure the service::telemetry::metrics::readers with Prometheus
• service: Revert Default internal metrics config now enables otel_scope_ labels (#12939, [#13344]) Reverting change temporarily due to prometheus exporter downgrade. This unfortunately re-introduces the bug that instrumentation scope attributes cause errors in Prometheus exporter. See http://github.com/open-telemetry/opentelemetry-collector/issues/12939 for details.
• builder: Remove undocumented handling of DIST_* environment variables replacements (#13335)

API Changelog

🛑 Breaking changes 🛑

• configgrpc: Update optional fields to use configoptional.Optional field for optional values. (#13252, [#13364]) Specifically, the following fields have been updated to configoptional:
• KeepaliveServerConfig.ServerParameters (KeepaliveServerParameters type)

• KeepaliveServerConfig.EnforcementPolicy (KeepaliveEnforcementPolicy type)

• xexporterhelper: Remove deprecated NewProfilesExporter function from xexporterhelper package (#13391)

💡 Enhancements 💡

• consumererror: Add new "Downstream" error marker (#13234) This new error wrapper type indicates that the error returned by a component's Consume method is not an internal failure of the component, but instead was passed through from another component further downstream. This is used internally by the new pipeline instrumentation feature to determine the outcome of a component call. This wrapper is not intended to be used by components directly.

• pdata/pprofile: Introduce Equal method on the Function type (#13222)

• pdata/pprofile: Introduce Equal method on the Link type (#13223)
• pdata/pprofile: Add new helper method SetFunction to set a new function on a line. (#13222)
• pdata/pprofile: Add new helper method SetLink to set a new link on a sample. (#13223)
• pdata/pprofile: Add new helper method SetString to set or retrieve the index of a value in the StringTable. (#13225)
