[[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:
