+.[Otel] Disable Process Scraper Of Hostmetrics Receiver. {elastic-agent-pull}https://github.com/elastic/elastic-agent/pull/7894[#https://github.com/elastic/elastic-agent/pull/7894]
+[%collapsible]
+====
+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.

+[[new-features-9.1.0]]
+=== New features
+
+The 9.1.0 release adds the following new and notable features.
+
+elastic-agent::
+
+* Adds A New Configuration Setting, `Agent.upgrade.rollback.window`. {elastic-agent-pull}https://github.com/elastic/elastic-agent/pull/8065[#https://github.com/elastic/elastic-agent/pull/8065] {elastic-agent-issue}https://github.com/elastic/elastic-agent/issues/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. {elastic-agent-pull}https://github.com/elastic/elastic-agent/pull/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' guidance:
