## Features

The KFP SDK 2.0.0 release contains features present in the KFP SDK v1's v2 namespace along with considerable additional functionality. A selection of these features include:
* An improved and unified Python-based authoring experience for [components](https://www.kubeflow.org/docs/components/pipelines/v2/components/) and [pipelines](https://www.kubeflow.org/docs/components/pipelines/v2/pipelines/)
