 After the stack is parsed, the following validation checks are performed:

-* If the scriptPubKey of ''triggerOut'' is not a witness program of the same version as the currently executing script, script execution MUST fail and terminate immediately.
+* If the scriptPubKey of ''triggerOut'' is not a witness program of the same version and same tapleaf version as the currently executing script, script execution MUST fail and terminate immediately.
 * Let the script constructed by taking the <code><leaf-update-script-body></code> and prefixing it with minimally-encoded data pushes of the <code><n-pushes></code> leaf-update script data items be called the ''leaf-update-script''.
 ** The leaf-update data items will be in the same order in the ''leaf-update-script'' as they appeared on the stack.
 * If the scriptPubKey of ''triggerOut'' does not match that of a taptree that is identical to that of the currently evaluated input, but with the leaf script substituted for ''leaf-update-script'', script execution when spending this output MUST fail and terminate immediately.
