+      description: |
+        The process scraper collects metrics for all available processes of a host without an easy way to limit
+        this to only report top N process for example. This results in quite big amount of timeseries.
+        Since this is not quite critical for any of the available UIs or dashboards we decide to disable
+        it temporarily until we find a better solution. Users that specifically need these metrics
+        can also enable it back manually.
+        Related to https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/39423.

+      description: |
+        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.

+::::{dropdown} Removed username and password default values for {{agent}}
+The default values for `username` and `password` have been removed for when {{agent}} is running in container mode. The {{es}} `api_key` can now be set in that mode using the `ELASTICSEARCH_API_KEY` environment variable.
+
+For more information, check [#5536]({{agent-pull}}5536).
+::::
+
+::::{dropdown} Changed Ubuntu-based Docker images for {{agent}}
+The default Ubuntu-based Docker images used for {{agent}} have been changed to UBI-minimal-based images, to reduce the overall footprint of the agent Docker images and to improve compliance with enterprise standards.
+
+For more information, check [#6427]({{agent-pull}}6427).
+::::
+
+::::{dropdown} Removed --path.install flag declaration from {{agent}} paths command
+The deprecated `--path.install` flag declaration has been removed from the {{agent}} `paths` command and its use removed from the `container` and `enroll` commands.
+
+For more information, check [#6461]({{agent-pull}}6461) and [#2489]({{agent-pull}}2489).
+::::
+
+::::{dropdown} Changed the default {{agent}} installation and upgrade
+The default {{agent}} installation and ugprade have been changed to include only the `agentbeat`, `endpoint-security` and `pf-host-agent` components.
+
+Additional components such as `apm` or `fleet` require passing the `--install-servers` flag or setting the `ELASTIC_AGENT_FLAVOR=servers` environment variable.
+
+For more information, check [#6542]({{agent-pull}}6542).

+## 9.0.1 [elastic-agent-9.0.1-breaking-changes]
+
+::::{dropdown} [otel] Disable process scraper of hostmetrics receiver.
+The process scraper collects metrics for all available processes of a host without an easy way to limit
+this to only report top N process for example. This results in quite big amount of timeseries.
+Since this is not quite critical for any of the available UIs or dashboards we decide to disable
+it temporarily until we find a better solution. Users that specifically need these metrics
+can also enable it back manually.
+Related to https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/39423.
+
+
+For more information, check [#7894](https://github.com/elastic/elastic-agent/pull/7894).

+
+
+### Fixes [elastic-agent-9.0.3-fixes]
+
+* Address a race condition that can occur in Agent diagnostics if log rotation runs while logs are being zipped. [#8215](https://github.com/elastic/elastic-agent/pull/8215) 
+* Use paths.TempDir for diagnostics actions. [#8472](https://github.com/elastic/elastic-agent/pull/8472) 
+* 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.

+
+  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.

+## 9.1.0 [elastic-agent-release-notes-9.1.0]
+
+_This release also includes: [Deprecations](/release-notes/deprecations.md#elastic-agent-9.1.0-deprecations)._
+
+### Features and enhancements [elastic-agent-9.1.0-features-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.
+  
+* 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
+  
+  This change is aligned with the respective Semantic Conventions&#39; guidance:
+  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
+* 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 [elastic-agent-9.1.0-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/arm64&#39;s 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
+* 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)

+
+### Fixes [elastic-agent-9.1.3-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)

+:::{dropdown} [Windows] {{agent}} does not process Windows security events
+
+**Applies to: {{agent}} 8.19.0, 9.1.0 (Windows only)**
+
+On August 1, 2025, a known issue was discovered where {{agent}} does not process Windows security events on hosts running Windows 10, Windows 11, and Windows Server 2022.
+
+For more information, check [Issue #45693](https://github.com/elastic/beats/issues/45693).
+
+**Workaround**
+
+No workaround is available at the moment, but a fix is expected to be available in {{agent}} 8.19.1 and 9.1.1.
+:::
+
+:::{dropdown} {{agents}} remain in an "Upgrade scheduled" state
+
+**Applies to: {{agent}} 8.18.0, 8.18.1, 8.18.2, 8.18.3, 8.18.4, 8.19.0, 9.0.0, 9.0.1, 9.0.2, 9.0.3, 9.1.0**
+
+On July 2, 2025, a known issue was discovered where {{agent}} remains in an `Upgrade scheduled` state when a scheduled {{agent}} upgrade is cancelled. Attempting to restart the upgrade on the UI returns an error: `The selected agent is not upgradeable: agent is already being upgraded.`.
+
+For more information, check [Issue #8778](https://github.com/elastic/elastic-agent/issues/8778).
+
+**Workaround**
+
+Call the [Upgrade an agent](https://www.elastic.co/docs/api/doc/kibana/operation/operation-post-fleet-agents-agentid-upgrade) endpoint of the Kibana Fleet API with the `force` parameter set to `true` to force-upgrade the {{agent}}:
+
+```powershell
+curl --request POST \
+  --url https://<KIBANA_HOST>/api/fleet/agents/<AGENT_ID>/upgrade \
+  --user "<SUPERUSER_NAME>:<SUPERUSER_PASSWORD>" \
+  --header 'Content-Type: application/json' \
+  --header 'kbn-xsrf: true' \
+  --data '{"version": "<VERSION>","force": true}'
+```
+
+To force-upgrade multiple {{agents}}, call the [Bulk upgrade agents](https://www.elastic.co/docs/api/doc/kibana/operation/operation-post-fleet-agents-bulk-upgrade) endpoint of the Kibana Fleet API with the `force` parameter set to `true`:
+
+```powershell

+
+:::{dropdown} [Windows] {{agent}} is unable to re-enroll into {{fleet}}
+
+**Applies to: {{agent}} 9.0.0, 9.0.1, 9.0.2 (Windows only)**
+
+On April 9, 2025, a known issue was discovered where an {{agent}} installed on Windows and previously enrolled into {{fleet}} is unable to re-enroll. Attempting to enroll the {{agent}} fails with the following error:
+
+```shell
+Error: the command is executed as root but the program files are not owned by the root user.
+```
+
+For more information, check [Issue #7794](https://github.com/elastic/elastic-agent/issues/7794).
+
+**Workaround**
+
+Until a bug fix is available in a later release, you can resolve the issue temporarily using the following workaround:
+
+1. Change the ownership of the {{agent}} directory:
+
+  ```shell
+  icacls "C:\Program Files\Elastic\Agent" /setowner "NT AUTHORITY\SYSTEM" /t /l
+  ```
+
+2. After the output confirms all files were successfully processed, run the `enroll` command again.

+
+:::{dropdown} [macOS] Osquery integration fails to start on fresh agent installs
+
+**Applies to: {{agent}} 9.0.0 and 9.0.1 (macOS only)**
+
+On May 26th, 2025, a known issue was discovered that causes the `osquery` integration to fail on new {{agent}} installations on macOS. During the installation process, the required `osquery.app/` directory is removed, which prevents the integration from starting.
+
+For more information, check [Issue #8245](https://github.com/elastic/elastic-agent/issues/8245).
+
+**Workaround**
+
+As a workaround, you can manually restore the `osquery.app/` directory as follows:
+
+1. Extract the {{agent}} package, but do not install it yet.
+
+2. Open the following file in the extracted directory:
+
+   ```
+   data/elastic-agent-68f3ed/components/agentbeat.spec.yml
+   ```
+
+3. Locate the `component_files` section at the top of the file. It should look similar to this:
+
+   ```yaml
+   version: 2
+   component_files:
+     - certs/*
+     - lenses/*
+     - module/*
+     - "osquery-extension.ext"
+     - "osquery-extension.exe"
+     - osqueryd
+     - "osqueryd.exe"
+   ```
+
+4. Add the following entry to the end of the list:
+
+   ```yaml
+     - "osquery.app/*"
