 ## Plugin System
 
 Since v2, semantic-release is equipped with a plugin system. The plugins are standalone binaries that use [hashicorp/go-plugin](https://github.com/hashicorp/go-plugin) as a plugin library. `semantic-release` automatically downloads the necessary plugins if they don't exist locally. The plugins are stored in the `.semrel` directory of the current working directory in the following format: `.semrel/<os>_<arch>/<plugin name>/<version>/`. The go-semantic-release plugins registry (https://registry.go-semantic-release.xyz/) is used to resolve plugins and to download the correct binary. With the new [plugin-registry](https://github.com/go-semantic-release/plugin-registry) service the API also supports batch requests to resolve multiple plugins at once and caching of the plugins.
