If the <code>$LATEST</code> version of this intent hasn't changed since you last updated it, Amazon Lex doesn't create a new version. It returns the last version you created.</p> <note> <p>You can update only the <code>$LATEST</code> version of the intent. You can't update the numbered versions that you create with the <code>CreateIntentVersion</code> operation.</p> </note> <p> When you create a version of an intent, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see <a>versioning-intro</a>. </p> <p>This operation requires permissions to perform the <code>lex:CreateIntentVersion</code> action. </p>

If you don't specify a checksum, Amazon Lex publishes the <code>$LATEST</code> version.
