# frame-metadata

Defines FRAME metadata types for [Substrate](https://github.com/paritytech/substrate) runtimes.

Originally part of the `substrate` repository, it was extracted here as part of https://github.com/paritytech/substrate/pull/8615.

## Versioning
Starting from `v12`, all historical metadata type definitions are retained. These can be enabled via features e.g. `v13`. The latest version is enabled by default.

### Tooling
The intention is to provide tooling here in the future to handle the different versions of metadata.
