# Review and publish

> Validate a draft, follow compilation, and activate a new version.

Publishing turns an editorial draft into a version the runtime can execute.

## Before publishing

Studio distinguishes between:

* **blocking errors**, which must be fixed before publishing;
* **warnings**, which deserve review but may not prevent publishing;
* the **diff**, which summarizes changes from the active version.

## Three stages

<Steps>
  <Step title="Validation">
    The server checks identifiers, references, question types, sub-objectives, and success information.
  </Step>

  <Step title="Compilation">
    An asynchronous job prepares the decision artifact. You can leave Studio; the job continues on the server.
  </Step>

  <Step title="Activation">
    If compilation succeeds, the new version becomes active for sessions created afterwards.
  </Step>
</Steps>

A failed compilation never replaces the active version. Fix the reported cause or publish again; visitors continue using the latest valid version.

<Note>
  An existing session keeps the version it was created with. Publishing therefore does not alter an ongoing conversation.
