Product: EDI platform

We released the following EDI platform features:

You can now lock guides in your account to prevent accidental changes or deletions. Any user in your Stedi account can lock a guide, but only an account admin can unlock them. To lock a guide, go to the **Actions** menu and select **Lock**.

When configuring an outbound test file, you can now review the EDI that Stedi will generate from your JSON test data. To generate an outbound test file, go to the [Files page](https://portal.stedi.com/app/core/file-executions), open the **Create file** menu, and select **Test outbound**.
