🛑 Breaking changes 🛑

all: Latest supported k8s version is moved from 1.17 to 1.21. (#43891)
cmd/otelcontribcol: Removing unmaintained component extension/ecstaskobserver (#43818)
exporter/elasticsearch: Upgrade profiles proto to 1.9.0 (#44031)
extension/googlecloudlogentry_encoding: Parse cloud armor logs into log record attributes instead of placing it in the body as is. (#43389)
pkg/ottl: Upgrade profiles proto to 1.9.0 (#44031)
processor/filter: Upgrade profiles proto to 1.9.0 (#44031)
processor/tail_sampling: Replace policy latency metric with total time spent executing specific sampling policy. (#42620)
The existing latency metric was misleading and expensive to compute. The new cpu time metric can be used to find expensive policies instead.
receiver/pprof: Upgrade profiles proto to 1.9.0 (#44031)
receiver/prometheus: The prometheus receiver no longer adjusts the start time of metrics by default. (#43656)
Disable the receiver.prometheusreceiver.RemoveStartTimeAdjustment | feature gate to temporarily re-enable this functionality. Users that need | this functionality should migrate to the metricstarttime processor, | and use the true_reset strategy for equivalent behavior.

🚀 New components 🚀

pkg/translator/pprof: move code from receiver/pprofreceiver to pkg/translator/pprof (#43975)
pprof is an established format. For a better integration with OTel move code to a dedicated component.
receiver/awslambda: Add scaffolding for the new awslambda receiver, for event-triggered receiving of data from S3 and CloudWatch. (#43504)
receiver/googlecloudpubsubpush: Add skeleton to the google pub sub push receiver. (#43503)
receiver/systemd: Report active state of systemd units. (#33532)
receiver/yanggrpc: New component YANG gRPC (#43840)

💡 Enhancements 💡

exporter/azureblob: Added serial_num_enabled and time_parser_enabled options to blob_name_format in Azure Blob Exporter to control random serial number appending and time parsing behavior. (#43603)
exporter/elasticsearch: Add support for latest OTEL SemConv version and fix Elasticsearch exporter ECS mapping for message.destination.name which is different for Elastic spans or transactions (#43805, #43806)
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)
Since franz-go now defaults to 10ms, it's best to allow users to configure this option to suit their needs.
extension/datadog: Adds collector resource attributes to collector metadata payload (#43979)
The Collector's resource attributes can be set under service::telemetry::resource.
extension/encoding: Add most of the AWS ELB fields to the AWSLogsEncoding. (#43757)
receiver/datadog: Adding log telemetry functionality to the existing datadog receiver component. (#43841)
receiver/github: Add include_span_events for GitHub Workflow Runs and Jobs for enhanced troubleshooting (#43180)
receiver/journald: Add root_path and journalctl_path config for running journald in a chroot (#43731)
receiver/prometheusremotewrite: Skip emitting empty metrics. (#44149)
receiver/prometheusremotewrite: prometheusremotewrite receiver now accepts metric type unspcified histograms. (#41840)
receiver/redis: Add redis metrics that are present in telegraf: cluster_enabled, tracking_total_keys, used_memory_overhead, used_memory_startup (#39859)
receiver/splunkenterprise: added pagination for search cases which may return more than the default 100 results (#43608)
receiver/webhookevent: Allow configuring larger webhook body size (#43544)
The receiver allows configuration a larger body buffer if needed.
It also returns an error if the body exceeds the configured limit.

🧰 Bug fixes 🧰

cmd/opampsupervisor: Redacts HTTP headers in debug message (#43781)
connector/datadog: Datadog connector no longer stalls after a downstream component errors (#43980)
exporter/awsxray: Fix conversion of the inProgress attribute into a Segment field instead of metadata (#44001)
exporter/datadog: Fix a panic from a race condition between exporter shutdown and trace export (#44068)
exporter/elasticsearch: Handle empty histogram buckets to not result in an invalid datapoint error. (#44022)
exporter/elasticsearch: Update the ecs mode span encode to correctly encode span.links ids as trace.id and span.id (#44186)
exporter/elasticsearch: Improve error message when an invalid Number data point is received. (#39063)
exporter/loadbalancing: Ensure loadbalancing child exporters use the OTLP type so backend creation succeeds (#43950)
exporter/stef: Fix STEF connection creation bug (#44048)
On some rare occasions due to a bug STEF exporter was incorrectly disconnecting just | created STEF connection causing connection error messages in the log. This fixes the bug.
extension/bearertokenauth: Remove error messages fsnotify: can't remove non-existent watch when watching kubernetes SA tokens. (#44104)
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.
This is acceptable as the component is in alpha stability.
receiver/sqlserver: Resolved inaccurate data sampling in query metrics collection. (#44303)
receiver/sqlserver: Fix incorrect logic in query metrics window calculation. (#44162)
receiver/sqlserver: Fixed a bug in effective value calculation of lookback time in top query collection. (#43943)
receiver/windowsservice: Fixed an error where incorrect permissions and bad error handling were causing the receiver to stop reporting metrics (#44087)
