### Features and enhancements

- Add support for logstash output to elastic agent standalone helm chart. [#10644](https://github.com/elastic/elastic-agent/pull/10644)
- Enable cpu and disk hostmetrics scrapers for Darwin configurations. [#11423](https://github.com/elastic/elastic-agent/pull/11423)
- Add support for downgrading a running Agents privileges from Fleet. [#10231](https://github.com/elastic/elastic-agent/pull/10231)
- Add awss3receiver to EDOT. [#10515](https://github.com/elastic/elastic-agent/pull/10515) [#604](https://github.com/elastic/obs-integration-team/issues/604)
- Add awslogsencodingextension to EDOT. [#11107](https://github.com/elastic/elastic-agent/pull/11107)
- Add opex to elastic-agent helm chart. This change adds the Opex-CCM support to the offical elastic-agent helm chart deployment. [#9363](https://github.com/elastic/elastic-agent/pull/9363)
- Add windowseventlogreceiver to EDOT. [#11418](https://github.com/elastic/elastic-agent/pull/11418)
- Allow setting component runtime per input type. [#11186](https://github.com/elastic/elastic-agent/pull/11186)
- Improve metrics monitoring coverage for OTel-based ingestion. [#11813](https://github.com/elastic/elastic-agent/pull/11813)
  Extend ingestion of OTel collector internal telemetry to give more detailed metrics, including support for both monitoring and non-monitoring components in the same collector.
- Allow manually initiating an upgrade rollback within a configurable window. [#11955](https://github.com/elastic/elastic-agent/pull/11955) [#6881](https://github.com/elastic/elastic-agent/issues/6881)
- Add SNMP receiver to EDOT Collector. [#12239](https://github.com/elastic/elastic-agent/pull/12239)
- Restore cloud-defend to the basic and complete Docker images. [#11795](https://github.com/elastic/elastic-agent/pull/11795)
- Make otel default runtime for system\metrics input. [#11613](https://github.com/elastic/elastic-agent/pull/11613)
- Update OTel Collector components to v0.141.0. [#11671](https://github.com/elastic/elastic-agent/pull/11671)
- Change default runtime for select metricbeat inputs. [#11754](https://github.com/elastic/elastic-agent/pull/11754)
  The following metricbeat inputs will use the otel runtime by default if the elasticsearch output is used:
  - activemq/metrics
- apache/metrics
- beat/metrics
- containerd/metrics
- docker/metrics
- elasticsearch/metrics
- etcd/metrics
- http/metrics
- jolokia/metrics
- kafka/metrics
- kibana/metrics
- linux/metrics
- logstash/metrics
- memcached/metrics
- mongodb/metrics
- mysql/metrics
- nats/metrics
- nginx/metrics
- rabbitmq/metrics
- sql/metrics
- stan/metrics
- statsd/metrics
- system/metrics
- vsphere/metrics
  This will result in a memory reduction since fewer agentbeat processes are started, because the otel runtime runs within the collector process.  If the policy is not compatible with the otel runtime, it will fall back to the process runtime.
- Improve input not supported error message to reference installation flavors. [#11825](https://github.com/elastic/elastic-agent/pull/11825)
- Add service.instance.id to k8s attributes in helm charts. [#11844](https://github.com/elastic/elastic-agent/pull/11844)
- Reduce installation size for all versions of the Elastic Agent. [#11821](https://github.com/elastic/elastic-agent/pull/11821)
  The Elastic Agent now ships with a single elastic-otel-collector binary that contains both the
  OTEL collector, beats receivers, and beat modules. This reduces the size of the Elastic Agent roughly
  ~200MB (amount depends on the platform). The elastic-agent.exe has also been greatly reduced from ~400M to ~75M.
- Add prometheusremotewrite receiver to EDOT. [#11937](https://github.com/elastic/elastic-agent/pull/11937)
- Replace elastic-agent/collector component name with elastic-otel-collector in self-monitoring. [#12364](https://github.com/elastic/elastic-agent/pull/12364)
  Make self-monitoring metrics consistently use the name of the new elastic-otel-collector binary executing the EDOT collector and beats receivers.
- Rotated container logs can be ingested using the helm-chart by setting `kubernetes.containers.logs.rotated_logs=true`. [#11783](https://github.com/elastic/elastic-agent/pull/11783) [#11559](https://github.com/elastic/elastic-agent/issues/11559)

- Fix kube-stack null template evaluation for Helm v4. [#11481](https://github.com/elastic/elastic-agent/pull/11481)
- Ensure the self-monitoring configuration accounts for the runtime components actually run in. [#11300](https://github.com/elastic/elastic-agent/pull/11300)
- Add environment.yaml file to diagnostics. [#11484](https://github.com/elastic/elastic-agent/pull/11484) [#10966](https://github.com/elastic/elastic-agent/issues/10966)
- Merge multiple agent keys when loading config. [#11619](https://github.com/elastic/elastic-agent/pull/11619) [#3717](https://github.com/elastic/elastic-agent/issues/3717)
- Hide healthcheckv2 from status output. [#11718](https://github.com/elastic/elastic-agent/pull/11718)
- Set path.home for beat receivers to components directory. [#11726](https://github.com/elastic/elastic-agent/pull/11726) [#48010](https://github.com/elastic/beats/issues/48010)
- Fix signature verification using the upgrade command with the --source-uri flag for fleet-managed agents. [#11826](https://github.com/elastic/elastic-agent/pull/11826) [#11152](https://github.com/elastic/elastic-agent/issues/11152)
- Handle curve_types to []curve_types conversion for elasticsearch config translation. [#11892](https://github.com/elastic/elastic-agent/pull/11892) [#11776](https://github.com/elastic/elastic-agent/issues/11776)
- Avoid uninstall and reinstalling service components on policy changes or reassignments. [#11740](https://github.com/elastic/elastic-agent/pull/11740)

- Fix FLEET_TOKEN_POLICY_NAME environment variable for the container command to handle cases where there are more than 20 agent policies available. [#12073](https://github.com/elastic/elastic-agent/pull/12073) [#12069](https://github.com/elastic/elastic-agent/issues/12069)
- This updates the kube-stack otel gateway collector endpoint to be OTEL_K8S_POD_IP as the previous value was causing an undefined log warning. [#12205](https://github.com/elastic/elastic-agent/pull/12205)
- Emit the correct error message when the app lock cannot be acquired. [#12225](https://github.com/elastic/elastic-agent/pull/12225)

## 9.2.6


### Features and enhancements

- Update OTel Collector components to v0.144.0. [#12735](https://github.com/elastic/elastic-agent/pull/12735)
- Add statsd receiver to EDOT Collector. [#12628](https://github.com/elastic/elastic-agent/pull/12628)


### Fixes

- Adds a missing dependency for Synthetics on wolfi docker image. [#12453](https://github.com/elastic/elastic-agent/pull/12453)


## 9.2.5


### Features and enhancements

- Support --prefix flag when installing from RPM. [#12263](https://github.com/elastic/elastic-agent/pull/12263)


### Fixes

- OSQuery - Add list capabilities to directories for interactive users. [#12189](https://github.com/elastic/elastic-agent/pull/12189)
  Fixing file permission issues for osquery extensions on Windows.
  It approches the problem by adding List Content permission to Logged in users so Directory permissions are not altered by UAC when traversing Agent directory structure.
  After this user wont be prompted with UAC and when opening e.g log files, instead user will run into access denied in editor of choice.
  Elevated editor must be used to open files that require elevated permissions.
- Update the kube-stack otel gateway collector endpoint to be OTEL_K8S_POD_IP as the previous value was causing an undefined log warning. [#12205](https://github.com/elastic/elastic-agent/pull/12205)
- Emit the correct error message when the app lock cannot be acquired. [#12225](https://github.com/elastic/elastic-agent/pull/12225)
- Fix elasticsearch retry behavior in OTEL runtime for reliable delivery. [#12455](https://github.com/elastic/elastic-agent/pull/12455)
  Elastic Agent running on the OTEL runtime now retries the same Elasticsearch response codes as standalone Beats, including 5xx errors. Previously, only 429 responses were retried, which could result in dropped events under certain failure conditions.

### Fixes

- Reduce memory usage by executing Elastic Agent self-monitoring inputs as OpenTelemetry collector receivers by default. [#10594](https://github.com/elastic/elastic-agent/pull/10594)
  Self-monitoring inputs which were previously executed as Beat sub-processes are now executed as receivers in a single OpenTelemetry collector sub-process.
  For a Fleet managed Elastic Agent running the default System integration, steady state memory usage is reduced by 11.5% (79.1 MB) on Linux, 34.5% (185.77 MB) on Windows, and 23.0% (115.9 MB) on MacOS.
  This is the first phase of work reducing the Elastic Agents memory footprint, memory reductions will continue in future releases.
- Fix issue where switching to OTEL runtime would cause data to be re-ingested. [#10857](https://github.com/elastic/elastic-agent/pull/10857)

- Agent cleans up downloads directory and the new versioned home if upgrade fails. [#9386](https://github.com/elastic/elastic-agent/pull/9386) [#5235](https://github.com/elastic/elastic-agent/issues/5235)
- When there is a disk space error during an upgrade, agent responds with clean insufficient disk space error message. [#9392](https://github.com/elastic/elastic-agent/pull/9392) [#5235](https://github.com/elastic/elastic-agent/issues/5235)
- Add Headers Setter extension to EDOT Collector. [#9903](https://github.com/elastic/elastic-agent/pull/9903) [#9889](https://github.com/elastic/elastic-agent/issues/9889)
- Update OTel components to v0.132.0. [#10033](https://github.com/elastic/elastic-agent/pull/10033)


### Fixes

- Include aggregated agent status in HTTP liveness checks. [#9673](https://github.com/elastic/elastic-agent/pull/9673) [#9576](https://github.com/elastic/elastic-agent/issues/9576)
- Reduce-default-telemetry-frequency. [#9987](https://github.com/elastic/elastic-agent/pull/9987)
  Reduce the default telemetry frequency to 60 seconds. This change aims to lower infrastructure costs and reduce label churn in time-series storage. High-cardinality labels sampled too frequently inflate storage and index size, and increase query latency with limited added value. Environments that require higher resolution can change the `collection_interval` for `hostmetrics`, `kubeletstats` and `k8s_cluster` receivers to a lower value.
- Fix stuck upgrade state by clearing coordinator overridden state after failed upgrade. [#9992](https://github.com/elastic/elastic-agent/pull/9992)
- Include components units status in HTTP liveness checks. [#10060](https://github.com/elastic/elastic-agent/pull/10060) [#8047](https://github.com/elastic/elastic-agent/issues/8047)

- Enable admin user to re-enroll unprivileged agent for windows. [#9623](https://github.com/elastic/elastic-agent/pull/9623) [#8544](https://github.com/elastic/elastic-agent/issues/8544)
- Treat exit code 284 from Endpoint binary as non-fatal. [#9687](https://github.com/elastic/elastic-agent/pull/9687)
- Ensure failed upgrade actions are removed from queue and details are set. [#9634](https://github.com/elastic/elastic-agent/pull/9634) [#9629](https://github.com/elastic/elastic-agent/issues/9629)


## 9.1.3


### Features and enhancements

- Adjust the timeout for Elastic Defend check command. [#9329](https://github.com/elastic/elastic-agent/pull/9329) [#9521](https://github.com/elastic/elastic-agent/pull/9521) [#9522](https://github.com/elastic/elastic-agent/pull/9522) [#9545](https://github.com/elastic/elastic-agent/pull/9545) [#9213](https://github.com/elastic/elastic-agent/pull/9213)
- Update OTel components to v0.130.0. [#9329](https://github.com/elastic/elastic-agent/pull/9329) [#9521](https://github.com/elastic/elastic-agent/pull/9521) [#9522](https://github.com/elastic/elastic-agent/pull/9522) [#9545](https://github.com/elastic/elastic-agent/pull/9545) [#9362](https://github.com/elastic/elastic-agent/pull/9362)


### Fixes

- Upgrade to Go 1.24.6. [#9287](https://github.com/elastic/elastic-agent/pull/9287)
- On Windows, retry saving the Agent information file to disk. [#9224](https://github.com/elastic/elastic-agent/pull/9224) [#5862](https://github.com/elastic/elastic-agent/issues/5862)
  Saving the Agent information file involves renaming/moving a file to its final destination. However, on Windows, it is sometimes not possible to rename/move a file to its destination file because the destination file is locked by another process (e.g. antivirus software). For such situations, we now retry the save operation on Windows.
- Correct hints annotations parsing to resolve only `${kubernetes.*}` placeholders instead of resolving all `${...}` patterns. [#9307](https://github.com/elastic/elastic-agent/pull/9307)
- Treat exit code 28 from Endpoint binary as non-fatal. [#9320](https://github.com/elastic/elastic-agent/pull/9320)
- Fixed jitter backoff strategy reset. [#9342](https://github.com/elastic/elastic-agent/pull/9342) [#8864](https://github.com/elastic/elastic-agent/issues/8864)
- Fix Docker container failing to start with no matching vars: ${env.ELASTICSEARCH_API_KEY:} and similar errors by restoring support for `:` to set default values. [#9451](https://github.com/elastic/elastic-agent/pull/9451) [#9328](https://github.com/elastic/elastic-agent/issues/9328)
- Fix deb upgrade by stopping elastic-agent service before stopping endpoint. [#9462](https://github.com/elastic/elastic-agent/pull/9462)


## 9.1.2

_No new features, enhancements, or fixes._

## 9.1.1


### Features and enhancements

- Add k8s leader elector Otel extension. [#9261](https://github.com/elastic/elastic-agent/pull/9261) [#9262](https://github.com/elastic/elastic-agent/pull/9262) [#9065](https://github.com/elastic/elastic-agent/pull/9065)


### Fixes

- Dont overwrite elasticsearch output headers from enrollment --headers flag. [#9199](https://github.com/elastic/elastic-agent/pull/9199) [#9197](https://github.com/elastic/elastic-agent/issues/9197)


## 9.1.0

_This release also includes: [Deprecations](/elastic/docs-builder/docs/2659/release-notes/elastic-agent/deprecations#elastic-agent-9.1.0-deprecations)._

### Features and enhancements

- Adds a new configuration setting, `agent.upgrade.rollback.window`. [#8065](https://github.com/elastic/elastic-agent/pull/8065) [#6881](https://github.com/elastic/elastic-agent/issues/6881)
  The value of the `agent.upgrade.rollback.window` setting determines the period after upgrading
  Elastic Agent when a rollback to the previous version can be triggered. This is an optional
  setting, with a default value of `168h` (7 days). The value can be any string that is parseable
  by [https://pkg.go.dev/time#ParseDuration](https://pkg.go.dev/time#ParseDuration).
- Remove resource/k8s processor and use k8sattributes processor for service attributes. [#8599](https://github.com/elastic/elastic-agent/pull/8599)
  This PR removes the `resource/k8s` processor in honour of the k8sattributes processor that
  provides native support for the Service attributes:
  [https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.127.0/processor/k8sattributesprocessor#configuring-recommended-resource-attributes](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.127.0/processor/k8sattributesprocessor#configuring-recommended-resource-attributes)
  This change is aligned with the respective Semantic Conventions guidance:
  [https://opentelemetry.io/docs/specs/semconv/non-normative/k8s-attributes/#service-attributes](https://opentelemetry.io/docs/specs/semconv/non-normative/k8s-attributes/#service-attributes)
- Add elastic.agent.fips to local_metadata.  [#7112](https://github.com/elastic/elastic-agent/pull/7112)
  Add elastic.agent.fips (bool) attribute to local_metadata sent with enroll and checkin requests.
  The value of this attribute indicates if the agent is a FIPS-capable distribution.
- Validate pbkdf2 settings when in FIPS mode. [#7187](https://github.com/elastic/elastic-agent/pull/7187)
- FIPS-capable agent file vault. [#7360](https://github.com/elastic/elastic-agent/pull/7360)
  Change elastic file vault implementation to allow variable length salt sizes
  only in FIPS enabled agents.  Increase default salt size to 16 for FIPS
  compliance. Non-FIPS agents are unchanged.
- With this change FIPS-capable agents will only be able to upgrade to other FIPS-capable agents. This change also restricts non-fips to fips upgrades as well. [#7312](https://github.com/elastic/elastic-agent/pull/7312) [#4811](https://github.com/elastic/ingest-dev/issues/4811)
- Updated the error messages returned for fips upgrades. [#7453](https://github.com/elastic/elastic-agent/pull/7453)
- Retry enrollment requests on any error. [#8056](https://github.com/elastic/elastic-agent/pull/8056)
  If any error is encountered during an attempted enrollment, the elastic-agent
  will backoff and retry. Add a new --enroll-timeout flag and
  FLEET_ENROLL_TIMEOUT env var to set how long it tries for, default 10m. A
  negative value disables the timeout.
- Remove deprecated otel elasticsearch exporter config `*_dynamic_index` from code and samples. [#8592](https://github.com/elastic/elastic-agent/pull/8592)
- Include the forwardconnector as an EDOT collector commponent. [#8753](https://github.com/elastic/elastic-agent/pull/8753)
  [https://github.com/open-telemetry/opentelemetry-collector/tree/main/connector/forwardconnector](https://github.com/open-telemetry/opentelemetry-collector/tree/main/connector/forwardconnector)
- Update OTel components to v0.129.0.
- Update APM Config extension to v0.4.0.
- Update Elastic Trace processor to v0.7.0.
- Update Elastic APM connector to v0.4.0.
- Update API Key Auth extension to v0.2.0.
- Update Elastic Infra Metrics processor to v0.16.0.


### Fixes

- Upgrade to Go 1.24.3. [#8109](https://github.com/elastic/elastic-agent/pull/8109)
- Correctly handle sending signal to child process. [#7738](https://github.com/elastic/elastic-agent/pull/7738) [#6875](https://github.com/elastic/elastic-agent/issues/6875)
- Preserve agent run state on DEB and RPM upgrades. [#7999](https://github.com/elastic/elastic-agent/pull/7999) [#3832](https://github.com/elastic/elastic-agent/issues/3832)
- Use --header from enrollment when communicating with Fleet Server. [#8071](https://github.com/elastic/elastic-agent/pull/8071) [#6823](https://github.com/elastic/elastic-agent/issues/6823)
  The --header option for the enrollment command now adds the headers to the communication with Fleet Server. This
  allows a proxy that requires specific headers present for traffic to flow to be placed in front of a Fleet Server
  to be used and still allowing the Elastic Agent to enroll.
- Address a race condition that can occur in Agent diagnostics if log rotation runs while logs are being zipped.
- Use paths.TempDir for diagnostics actions. [#8472](https://github.com/elastic/elastic-agent/pull/8472)
- Use Debian 11 to build linux/arm to match linux/amd64. Upgrades linux/arm64s statically linked glibc from 2.28 to 2.31. [#8497](https://github.com/elastic/elastic-agent/pull/8497)
- Relax file ownership check to allow admin re-enrollment on Windows. [#8503](https://github.com/elastic/elastic-agent/pull/8503) [#7794](https://github.com/elastic/elastic-agent/issues/7794)
  On Windows, the agent previously enforced a strict file ownership (SID) check during re-enrollment, which prevented legitimate admin users from re-enrolling the agent if the owner did not match. This PR changes the Windows-specific logic to a no-op, allowing any admin to re-enroll the agent. This restores usability for admin users, but reintroduces the risk that privileged re-enrollment can break unprivileged installs. The Unix-specific ownership check remains unchanged.
- Remove incorrect logging that unprivileged installations are in beta. [#8715](https://github.com/elastic/elastic-agent/pull/8715) [#8689](https://github.com/elastic/elastic-agent/issues/8689)
  Unprivileged installations went GA in 8.15.0: [https://www.elastic.co/docs/reference/fleet/elastic-agent-unprivileged](https://www.elastic.co/docs/reference/fleet/elastic-agent-unprivileged)
- Ensure standalone Elastic Agent uses log level from configuration instead of persisted state. [#8784](https://github.com/elastic/elastic-agent/pull/8784) [#8137](https://github.com/elastic/elastic-agent/issues/8137)
- Resolve deadlocks in runtime checkin communication. [#8881](https://github.com/elastic/elastic-agent/pull/8881) [#7944](https://github.com/elastic/elastic-agent/issues/7944)
- Removed init.d support from RPM packages. [#8896](https://github.com/elastic/elastic-agent/pull/8896) [#8840](https://github.com/elastic/elastic-agent/issues/8840)
