### 4.83.1 SP3 Release Notes

| MES-7681 | Core | Production | Fixed - Data retention now purges all batches outside of the cutoff date instead of limiting it to 1000 batches per day. |

| MES-7458 | Batch | **Improved:**<br><ul><li><a href="/smart/project-imported-manual/system-mes-batch-queue-getparametervalue-batchqueueentry-path" target="_blank">batch.queue.getParameterValue(...)</a> and <a href="/smart/project-imported-manual/system-mes-batch-queue-getparametervalueasstring-batchqueueentry-path" target="_blank">getParameterValueAsString(..)</a> script functions have been updated to not require a Batch to be running to get the value of a parameter</li></ul><br><br>| ![Success](/resources/Storage/release-notes-publication/Success.png) | For parameters with a **Calculation Expression**, if the batch is not active, the last calculated value is returned (if available); otherwise, the Calculation Expression is returned. |<br>| --- | --- |<br><br><ul><li>Updated batch.queue.* script methods to accept either a <a href="/smart/project-imported-manual/batchqueueentry-object" target="_blank">BatchQueueEntry object</a> or a <span onclick="showDropdown(this,&#39;chpu17775847862470&#39;);" class=" CHHotspot CHDropdownHotspot">Batch ID</span>, where possible.<br><br><div id="chpu17775847862470" class="Article_hiddenBlock CHDropdown"><h4 style="" id="h4_1785924805" data-has-heading-anchor="true">batchID</h4><p>A&#160;<strong>batch ID</strong>&#160;is a unique identifier assigned to a batch within the Sepasoft MES (Manufacturing Execution System). It is used to reference and manage specific batches during their lifecycle in the batch queue. The batch ID is crucial for retrieving associated control recipes and logic objects, as well as for tracking the status and parameters of the batch.</p>
<p>For example, in the function&#160;<a href="/articles/user-manual/system-mes-batch-queue-getbatchobjects" onclick="return n(&#39;!user-manual/system-mes-batch-queue-getbatchobjects&#39;,this);">system.mes.batch.queue.getBatchObjects(batchID)</a>, the batch ID is passed as a parameter to retrieve the control recipe and logic objects associated with that specific batch.<br></p>
