## ✨ Highlights

### New CLI command `sanity migration create|list|run`

You can now create, list, and run content migrations from the Sanity CLI. The new tooling lets you scaffold content migrations as code and run them in dry and production mode. It also introduces a new API for defining content migration with helper functions (`defineMigration()`).

You can explore [the documentation for schema and content migrations](https://www.sanity.io/docs/content-lake/schema-and-content-migrations); or learn more by running the following CLI commands in a Sanity Studio project folder:

```
sanity migration --help

```

You can run `sanity migration create` to explore our new content migration templates.

### New CLI command: `sanity schema validate`

You can now validate a Sanity Studio schema with the CLI command `sanity schema validate`. Among other things, it will identify problems with your schema-type definitions. This tooling can be useful for running in CI/CD pipelines or debugging your schema configuration.

Learn more by running:

```
sanity schema validate ---help

```
