 <summary>Highlights from the upstream Collector changelog</summary>
 
-### 💡 Enhancements 💡
-- `cmd/mdatagen`: Improve validation for resource attribute `enabled` field in metadata files (#12722)
-  Resource attributes now require an explicit `enabled` field in metadata.yaml files, while regular attributes
-  are prohibited from having this field. This improves validation and prevents configuration errors.
-- `all`: Changelog entries will now have their component field checked against a list of valid components. (#13924)
-  This will ensure a more standardized changelog format which makes it easier to parse.
-- `pkg/pdata`: Mark featuregate pdata.useCustomProtoEncoding as stable (#13883)
-- all: Mark configoptional as stable (#13403)
-- all: Mark configauth module as 1.0 (#9476)
-- `pkg/pdata`: Mark featuregate pdata.useCustomProtoEncoding as stable (#13883)
-- `redactionprocessor`: Add support for URL sanitization in the redaction processor. (#41535)
-- `receiver/k8seventsreceiver`: Added support for Leader Election into k8seventsreceiver using k8sleaderelector extension. (#42266)
-- `receiver/k8sobjectsreceiver`: Switch to standby mode when leader lease is lost instead of shutdown (#42706)
-- `processor/resourcedetection`: Add support for DigitalOcean in resourcedetectionprocessor (#42803)
-- `processor/resourcedetection`: Add support for upcloud in resourcedetectionprocessor (#42801)
-- `hostmetricsreceiver`: Add useMemAvailable feature gate to use the MemAvailable kernel's statistic to compute the "used" memory usage (#42221)
-- `tailsamplingprocessor`: Add support for extensions that implement sampling policies. (#31582)
-  Extension support for tailsamplingprocessor is still in development and the interfaces may change at any time.
-- `telemetrygen`: Add span links support to telemetrygen (#43007)
-  The new --span-links flag allows generating spans with links to previously created spans.
-  Each span can link to random existing span contexts, creating relationships between spans for testing
-  distributed tracing scenarios. Links include attributes for link type and index identification.
-- `telemetrygen`: Add load size to telemetrygen metrics and logs. (#42322)

-- `receiver/k8seventsreceiver`: Prevent potential panic in the events receiver by safely checking that informer objects are *corev1.Event before handling them. (#43014)
-- `processor/k8sattributes`: Use podUID instead podName to determine which pods should be deleted from cache (#42978)
-- `telemetrygen`: Publish int and bool attributes for logs (#43090)
-- `statsdreceiver`: Fix a data race in statsdreceiver on shutdown (#42878)
-
-🛑 Breaking changes 🛑
-- `pkg/exporterhelper`: Remove all experimental symbols in exporterhelper (#11143)
-  They have all been moved to xexporterhelper
-- `spanmetricsconnector`: Exclude all resource attributes in spanmetrics (#42103)
-  This change aligns with the ServiceGraph implementation and may introduce a breaking change:
-  Users utilizing Prometheus remote write will not experience a breaking change.
-  Users using OTLP/HTTP may encounter a breaking change.
-  The change is currently guarded by the feature gate connector.spanmetrics.excludeResourceMetrics and is disabled by default.
-  It will be enabled by default in the next release.
-- `spanmetricsconnector`: Change default duration metrics unit from ms to s (#42462)
-  This change introduces a breaking change, which is now guarded by the feature gate connector.spanmetrics.useSecondAsDefaultMetricsUnit.
-  Currently, the feature gate is disabled by default, so the unit will remain ms. After one release cycle, the unit will switch to s and the feature gate will also be enabled by default.
-
-  🚩 Deprecations 🚩
--  all: service/telemetry.TracesConfig is deprecated (#13904)
-  This type alias has been added to otelconftelemetry.TracesConfig,
-  where the otelconf-based telemetry implementation now lives.
-
-🚀 New components 🚀
-
-- `resourcedetectionprocessor`: Added Oracle Cloud resource detection support to resourcedetectionprocessor, enabling automatic population of Oracle Cloud-specific resource attributes. (#35091)
-  This update allows the OpenTelemetry Collector to detect and annotate telemetry with Oracle Cloud resource metadata when running in Oracle Cloud environments.
-  Includes new unit tests and documentation.
