 Nextflow now uses the [Nextflow plugin registry](https://registry.nextflow.io/) to download plugins in a more efficient and scalable manner.

-Plugin developers will not be able to submit PRs to the legacy plugin index once the plugin registry is generally available. Plugins should be updated to publish to the Nextflow plugin registry using the {ref}`Nextflow Gradle plugin <gradle-plugin-page>` instead. See {ref}`plugin-registry-page` for details.
