🛑 Breaking changes 🛑

• all: fix pprofile DurationNano to be a TypeUint64 (#​44397)

• cmd/otelcontribcol: Removing unmaintained component exporter/carbon (#​38913)

• connector/spanmetrics: Add a feature gate to use the latest semantic conventions for the status code attribute on generated metrics. | This feature gate will replace the status.code attribute on the generated RED metrics with otel.status_code. | It will also replace the values STATUS_CODE_ERROR and STATUS_CODE_OK with ERROR and OK to align with the latest conventions. (#​42103)
  This change is made to align with the latest semantic conventions. | The feature gate is disabled by default, but can be enabled with --feature-gates spanmetrics.statusCodeConvention.useOtelPrefix | or explicitly disabled with --feature-gates -spanmetrics.statusCodeConvention.useOtelPrefix.

• exporter/clickhouse: Add EventName column to logs table (#​42584)
  This column is optional for existing deployments. See project README for notes on how to upgrade your logs table.

• exporter/clickhouse: Add columns for tracking JSON paths in logs + traces (#​43109)
  The JSON columns now include a helper column for keeping track of what keys are inside of the JSON object.
  This change also introduces schema detection logic to reduce breaking changes whenever a column is added.
  Existing users can enable these features by manually adding all the new columns to their table.

• exporter/kafka: exporter.kafkaexporter.UseFranzGo feature gate moved to Stable and is now always enabled (#​44565)

  • New config: create_directory (bool) and directory_permissions (octal string, e.g. "0755").
  • When enabled, the exporter creates the parent directory of path on start.
  • group_by uses the configured permissions when creating per-attribute directories.

• exporter/googlecloudpubsub: Update to cloud.google.com/go/pubsub/v2. (#​44465)

• exporter/googlecloudpubsub: Add encoding extension support (#​42270, #​41834)
  Add encoding extension support for the payload on Pub/Sub. As having custom extensions means the Pub/Sub attributes
  cannot be auto discovered additional functionality has been added to set the message attributes.

• exporter/prometheus: Add without_scope_info to omit otel scope info from prometheus exporter metrics (#​43613)

• exporter/prometheus: Add support to exponential histograms (#​33703)

• exporter/signalfx: Makes sending tags from SignalFx Exporter configurable (#​43799)

  This includes adding support for the new gcp.load_balancing.proxy_nlb attributes.
  See the README for more details.

• extension/headers_setter: Add support for chaining with other auth extensions via additional_auth configuration parameter. This allows combining multiple authentication methods, such as OAuth2 for bearer token authentication and custom headers for additional metadata. (#​43797)
  The additional_auth parameter enables the headers_setter extension to work in conjunction
  with other authentication extensions like oauth2client. The additional auth extension is called
  first to apply its authentication, then headers_setter adds its configured headers on top.

• extension/observer: Add container name, container ID, and container image to port endpoint (#​41309)

• pkg/ottl: Add ParseSeverity function to define mappings for log severity levels. (#​35778)

  • Collectors not running on Oracle Cloud return an empty resource and no error, since we don't expect this case to work.
  • If the Oracle Cloud platform is detected but metadata fetch fails, the error is now logged and signaled to the processor, since we do expect this case to work.

• processor/tail_sampling: Add bytes_limiting policy type, sample based on the rate of bytes per second using a token bucket algorithm. (#​42509)

• processor/tail_sampling: Adaptive expected_new_traces_per_sec to improve performance lower bound (#​43561)

• receiver/googlecloudpubsub: Update to cloud.google.com/go/pubsub/v2. (#​44466)

🧰 Bug fixes 🧰

• cmd/opampsupervisor: Fix supervisor passthrough logs overflow by using bufio.Reader instead of bufio.Scanner (#​44127)

• cmd/opampsupervisor: Fix data race in remoteConfig field by using atomic pointer for thread-safe concurrent access (#​44173)

• connector/routing: Fix routing to default route when error occurs (#​44386)
  Before we used to send everything (even records match without error) to the default pipeline, |
  after this change only entries that return error will be "ignored" and if no other rule in the |
  table picks them will be sent to the default rule.

• exporter/clickhouse: Fix TLS configuration being ignored when only ca_file is provided and no cert/key files are set. (#​43911)
  This change ensures server-side TLS validation works correctly even without client certificates.

• exporter/elasticsearch: Fix CloudID parsing to correctly handle Elastic Cloud IDs when sent with multiple dollar sign separators (#​44306)
  The CloudID decoder was incorrectly using strings.Cut() which only splits on the first delimiter,
  causing malformed URLs when the decoded CloudID contained multiple $ separators. Changed to use
  strings.Split() to match the reference implementation from go-elasticsearch library.

• extension/awslogs_encoding: address the SIGSEGV occurring when processing control_message messages. (#​44231)

• extension/awslogs_encoding: Fix ALB log request_line parsing for valid formats and avoid errors (#​44233)

• pkg/ottl: Fixed OTTL grammar to treat the string literal "nil" as ordinary text instead of a nil value. (#​44374)

• pkg/ottl: Return errors when OTTL context setters receive values of the wrong type (#​40198)
  Introduces ctxutil.ExpectType and updates log, metric, and scope setters to surface type assertion failures.

• pkg/ottl: Fix TrimPrefix/TrimSuffix function name. (#​44630)
  This change also adds a featuregate "ottl.PanicDuplicateName" to control the behavior of panicing when duplicate
  names are registered for the same function.

• processor/k8sattributes: k8sattributesprocessor now respects semantic convention resolution order for service.namespace (#​43919)
  Previously, when service.namespace was included in the extract metadata configuration, the processor
  would incorrectly allow k8s.namespace.name to override explicitly configured service namespace values
  from OpenTelemetry annotations (e.g., resource.opentelemetry.io/service.namespace). Now the processor
  correctly follows the semantic convention resolution order, where annotation values take precedence over
  inferred Kubernetes namespace names.

• processor/k8sattributes: Fix incorrect pod metadata assignment when host.name contains a non-IP hostname (#​43938)
  The processor now correctly validates that host.name contains an IP address before using it for pod association.
  Previously, textual hostnames were incorrectly used for pod lookups, causing spans and metrics from one workload
  to receive metadata from unrelated pods that shared the same hostname.

• receiver/awsxray: Fix incorrect span kind when translating X-Ray segment to trace span with parent ID (#​44404)

• receiver/azuremonitor: Collect only supported aggregations for each metric (501 not implemented issue) (#​43648)
  Some metrics were not collected because we requested all available aggregation types. This led to 501 errors, as the Azure API returned responses indicating that certain aggregations were not implemented.
  We now use the supported aggregations field from each metric definition to filter and request only the aggregations that are actually supported.
  The user can expect less 501 errors in the logs and more metrics in the results.

• receiver/datadog: Utilizes thread safe LRU packages (#​42644)

• receiver/github: Adds corrections to span times when GitHub sends incorrect start and end times. (#​43180)

• receiver/libhoney: Allow single events and uncompressed requests (#​44026, #​44010)
  The receiver required events to be wrapped in an array before. The single-event format
  was allowed by Honeycomb's API so we have added it here.
  This fix also allows uncompressed requests again

• receiver/sqlquery: Fix a bug in the sqlqueryreceiver where an error is returned if the query returned a null value. This is now logged as a warning and logs with null values are ignored. (#​43984)

• receiver/systemd: This allows systemd receiver to be used in collector config (#​44420)

• exporter/elasticsearch: Add helpful error hint for illegal_argument_exception when using OTel mapping mode with Elasticsearch < 8.12 (#​39282)
  When using OTel mapping mode (default from v0.122.0) with Elasticsearch versions < 8.12,
  the exporter now provides a more descriptive error message explaining that OTel mapping mode
  requires Elasticsearch 8.12+ and suggests either upgrading Elasticsearch or using a different
  mapping mode. This helps users who encounter the generic illegal_argument_exception error
  understand the root cause and resolution steps.

• exporter/googlecloudstorage: Add googlecloudstorageexporter to the contrib distribution (#​44063)

• exporter/kafka: Adds a new configuration option to the Kafka exporter to control the linger time for the producer. (#​44075)

• processor/k8sattributes: The fix is on k8sattributes processor to only set k8s.pod.ip attribute when it is requested in the extract.metadata configuration. (#​43862)
  Previously, the k8s.pod.ip attribute was always populated, even if it was not included in the extract.metadata list.
  This fix ensures that k8s.pod.ip is set only when explicitly requested, aligning the processor behavior with configuration expectations.

• receiver/ciscoos: Rename receiver component name from ciscoosreceiver to ciscoos to follow naming conventions. (#​42647)
  Users must update their collector configuration from ciscoosreceiver/device to ciscoos/device.

• exporter/kafka: franz-go: Fix underreported kafka_exporter_write_latency metric (#​43803)

• exporter/loadbalancing: Fix high cardinality issue in loadbalancing exporter by moving endpoint from exporter ID to attributes (#​43719)
  Previously, the exporter created unique IDs for each backend endpoint by appending the endpoint
  to the exporter ID (e.g., loadbalancing_10.11.68.62:4317). This caused high cardinality in metrics,
  especially in dynamic environments. Now the endpoint is added as an attribute instead.

• receiver/icmpcheckreceiver: Add initial skeleton of ICMP check receiver (README, config, factory, metadata) with In Development stability. (#​29009)
• receiver/redfish: adds a redfish receiver (#​33724)

💡 Enhancements 💡

• all: Changelog entries will now have their component field checked against a list of valid components. (#​43179)
  This will ensure a more standardized changelog format which makes it easier to parse.

• cmd/telemetrygen: Enable creation of attributes with values of slice type (#​39018)

• exporter/coralogix: Add HTTP/protobuf protocol support alongside existing gRPC transport. (#​43216)
  The exporter now supports both gRPC (default) and HTTP/protobuf protocols for sending telemetry data.
  HTTP transport enables proxy support and provides an alternative for environments where gRPC is restricted.
  Configure using the protocol field with values "grpc" or "http".

• exporter/datadog: Make defaults for sending_queue::batch section to work out of the box with Datadog API intake limits. (#​43082)

• exporter/elasticsearch: Support experimental 'encoding.format' scope attribute for dataset routing. (#​42844)

• exporter/kafka: Add support for partitioning log records by trace ID (#​39146)

• exporter/prometheus: Enable sending_queue section for the Prometheus exporter. (#​42629)

• extension/awslogs_encoding: Add feature gate to set aws.vpc.flow.start timestamp field to ISO8601 format (#​43392)
  Feature gate ID: extension.awslogsencoding.vpcflow.start.iso8601
  When enabled, the aws.vpc.flow.start field will be formatted as an ISO-8601 string
  instead of a Unix timestamp integer in seconds since epoch. Default behavior remains unchanged for backward compatibility.
  Enable with: --feature-gates=extension.awslogsencoding.vpcflow.start.iso8601

• extension/encoding: Add user_agent.original, destination.address, destination.port, url.domain to ELB access logs (#​43141)

• internal/kafka: Log a hint when broker connections fail due to possible TLS misconfiguration (#​40145)

• pkg/ottl: Add XXH3 Converter function to converts a value to a XXH3 hash/digest (#​42792)

• pkg/sampling: Note that pkg/sampling implements the new OpenTelemetry specification (#​43396)

• processor/filter: Add profiles support (#​42762)

• processor/isolationforest: Add adaptive window sizing feature that automatically adjusts window size based on traffic patterns, memory usage, and model stability (#​42751)
  The adaptive window sizing feature enables dynamic adjustment of the isolation forest sliding window size based on:

  • Traffic velocity and throughput patterns
  • Memory usage and resource constraints
  • Model stability and performance metrics
    This enhancement improves resource utilization and anomaly detection accuracy for varying workload patterns.

• processor/resourcedetection: Add Openstack Nova resource detector to gather Openstack instance metadata as resource attributes (#​39117)
  The Openstack Nova resource detector has been added to gather metadata such as host name, ID, cloud provider, region, and availability zone as resource attributes, enhancing the observability of Openstack environments.

• processor/resourcedetection: Add Azure availability zone to resourcedetectionprocessor (#​40983)

• receiver/azuremonitor: parallelize calls by subscriptions in Batch API mode (#​39417)

• receiver/ciscoosreceiver: Add ciscoosreceiver to collect metrics from Cisco OS devices via SSH (#​42647)
  Supports SSH-based metric collection from Cisco devices including:

  • System metrics (CPU, memory utilization)
  • Interface metrics (bytes, packets, errors, status)
  • Configurable scrapers for modular metric collection
  • Device authentication via password or SSH key

• receiver/gitlab: Add span attributes in GitLab receiver ([#​35207](https://redirect.github.com/open-telemetry/opentelemetry-c
