### 4.83.1 SP6 Release Notes

| MES-7694 | Bug | Batch | Fixed - Added missing context when resolving parameter paths that contain {} segments so referenced parameters can be found as expected. |
| --- | --- | --- | --- |
| MES-7874 | Bug | Batch | Fixed - an issue where OPC and Reference tags could retain an unresolved initial value when the first read returned Uncertain\_InitialValue. The system now queues those tags for another read attempt so the correct value can be retrieved. |
| MES-7873 | Bug | Batch | Fixed - an issue where writes to OPC and Reference tags could experience an unintended delay of up to 5 seconds. |

| MES-7830 | Bug | Batch | Fixed - Batches no longer get stuck in ABORTING if an active phase transitions to IDLE before all phase have gone to ABORTED |
| --- | --- | --- | --- |
| MES-7828 | Bug | Batch | Fixed - Electronic Batch Record history preserves step-specific parameter names |
| MES-7821 | Bug | Batch | Fixed - Commas are allowed in batch names. |
| MES-7792 | Bug | Batch | Fixed - Rapidly writing to Batch tags no longer triggers a race condition where stale writes overwrite fresh writes.<br><br><br><br>Fixed - De-syncs between State, State\_Number, State\_Number\_Ack, and the Batch Recipe Monitor have been prevented. |
| MES-7756 | Bug | Batch | Fixed - Equipment Phases can no longer get an unexpected HOLD command after going back to RUNNING |
| MES-7378 | Bug | Batch | Fixed - Disable\_Complete now correctly functions as intended and phases remain active until the next instance of Disable\_Complete = False completes. |
| MES-7186 | Bug | Batch | Fixed - Disable\_Complete now correctly functions as intended and phases remain active until the next instance of Disable\_Complete = False completes. |
| MES-4899 | Improvement | Batch | **Fixed:**<br><ul><li>Fixed parameter path handling in Batch Recipe Editor component so valid parameter paths are handled correctly<br><br></li><li>Fixed parameter path handling when the placeholder {} segment is used for referencing a parameter on a Unit Procedure or Operation step in the calculation expression of a parameter on that Unit Procedure or Operation logic. e.g., param(&quot;{}.SomeParam&quot;)<br><br></li><li>Changed parameter path handling for Transition_Expression and Parameter_Path (for SetParameter and ValuePrompt phases) back to previous behavior that allows Parameters to be referenced without specifying a step or logic identifier (e.g., &quot;MyParam&quot;)<br><br></li><li>Fixed issue causing inline calculation expression error to not have a clickable link to the error position when only a single error is returned<br><br></li><li>Fixed issue causing validation for SetParameter and ValuePrompt phases to fail when used in a template and the Parameter_Path is for a parameter &quot;outside&quot; of the template logic (e.g., path to a procedure param)<br><br></li><li>Fixed issue causing validation for Transitions to fail in templates when the Transition_Expression contains a path to a parameter &quot;outside&quot; of the template logic (e.g., path to a procedure param)</li></ul><br>**Improved:**<br><ul><li>Updated calculation expression error messages to use &quot;friendly paths&quot; instead of UUID paths so it&#39;s easier for users to diagnose issues with calculation expressions during recipe execution<br><br></li><li>Changed default stepName generation when a stepName is not provided when adding steps to a logic object in scripting to use the same generation as the Recipe Editor component (first char of logicType + stepOrder)</li></ul><br>**Added:**<br><ul><li>Added more function overloads for addStep method on batchMasterLogic objects to give scripting users more ways to easily add a step to a masterLogic object. At minimal, the phaseName or a phaseLink must be provided. The rest of the arguments can be omitted and will be generated/use the next available stepOrder or name. If the phase type is Unit Procedure or Operation, the logic link or logic object reference must also be provided.<br><br></li><li>Added convenience synonym methods to BatchQueueEntry and BatchRecipe objects for scripting</li></ul> |
| MES-4182 | Improvement | Batch | Added - Templates used in Batch Recipes are read-only blocks that can be synchronized with the source template. Breaking the link to the source template turns the template into a normal recipe element that can be modified. |
| MES-7857 | Bug | Core | Fixed - Prevent invalid JSON from being generated by system.mes.exportConfiguration |

| MES-7692 | Bug | Perspective | Perspective components bound to MESObjectSelector now clear their displayed data when &lt;None&gt; is selected (empty equipment/location path), instead of showing stale results from the previous selection. |
| MES-7647 | Bug | SPC | Fixed - The Perspective SPC attributes will no longer cache incorrect calculations in Analysis, when they should have been invalidated.<br><br><br><br>Fixed - The Vision SPC attribute value charts will no longer assign measurements to the wrong attributes.<br><br><br><br>Fixed - The Vision SPC charts will no longer allow the same attribute filter to be used multiple times.<br><br><br><br>Fixed - The Perspective P, NP, C, and U charts will no longer show attributes in the table that were explicitly filtered out. |
| MES-7634 | Bug | SPC | Fixed - Pareto and Box-and-Whisker SPC charts return expected data after sample definition renames, including names that contain dashes. |
