- No changes.
- Java bindings are not packaged with OpenStudio. To use them see our [developer page](https://openstudio.nrel.gov/developers) for guidance on building OpenStudio.

OpenStudio RunManager
- The RunManager application has been deprecated in favor of the OpenStudio and ParametricAnalysisTool applications. The RunManager library will remain available.

Known Issues

The following are issues known at the time of publication of these release notes. Please contact openstudionrel.gov if you require further assistance.

Known Issues Common to All Platforms

OpenStudio SketchUp Plug-in
- If you use copy multiple on group-level OpenStudio objects, you will get one extra copy. The extra group is created by the first copy-and-paste operation and is not removed when the copy multiple occurs. To address this, after you perform a copy multiple procedure on groups or spaces, press delete. The objects you need to delete should already be selected. If you are copying loose surfaces such as windows, there are no problems, as SketchUp will merge equivalent surfaces. [issue 28]
- Using SketchUp's undo operation on OpenStudio model elements may produce unexpected results. [issues 54 and 150]
- SKP and OSM link is not maintained when files are relocated. However, you can manually re-establish that link. When opening a SketchUp file, launch SketchUp and then open the SketchUp file. If that doesn't work you can also directly load the OSM file, bypassing the SKP file. [issue 409]
- It is possible for the OpenStudio plug-in to conflict with other SketchUp plug-ins. If you suspect this is a problem, try testing with other plug-ins disabled, or contact openstudionrel.gov for assistance. [issue 26]
- Using "Intersect" in the surface matching dialog can result in a crash or unexpected results. This is more common with models that were imported from other CAD formats at some point in the workflow. It is a good idea to save prior to using this to avoid any loss of data. This is related to an underlying SketchUp bug. [issue 168]
- "Project Loose Geometry" can crash SketchUp. It is a good idea to save prior to using this to avoid any loss of data. [issue 484]
- Adjacent stacked spaces in same zones may result in incorrect area and likely loads as well. [issue 561]
- SaveAs in SketchUp corrupts measures in model. To avoid this, only add measures into model after work in SketchUp is done. [issue 754]
- Using AutoSave in SketchUp can overwrite changes made in OS app if the file is open in both locations. [issue 899]

If your OpenStudio model crashes SketchUp or has unexpected behavior please forward it to OpenStudioNREL.gov with a description of the problem. Please also include the directory that has the same name as the OSM file. You can attach it as a zip file.

OpenStudio Application
- Similar thermostats assigned in the SketchUp Plug-in are shared across thermal zones in the OpenStudio application. Changing or turning off one will do the same to others. [issue 123]
- The view does not always refresh correctly when you delete a material from a construction. If you still see a material after clicking the "x", switch away from and back to the object to refresh the view. [issue 196]
- OS App Schedule Editor allows entering values outside of type limits. [issue 531]
- All drop zones under Water Use Equipment Definitions doesn't enforce schedule types. [issue 532]
- Removing CoilHeatingWater objects can result in orphaned hot water coils. [issue 594]
- Some HVAC components in OpenStudio are missing from the HVAC Library (e.g. Fan:OnOff). [issue 599]
- Several objects in OpenStudio appear to accept erroneous input values, but seems like it is just displaying the erroneous value and not storing it. [issue 656]
- Attempting to autosize a WaterHeater will result in an error. [issue 669]
- Entering an invalid date on the Utility Bills subtab crashes OpenStudio. [issue 739]
- To enable set point schedule drop zones on the Thermal Zones tab, you need to first turn on the thermostat.
- The Site / Utility Rates subtab in the workflow is marked as "coming soon," and will be completed in an upcoming release of OpenStudio.
- The default reporting measures used for the results tab show results in IP units, and do not react to changes in the user's unit preferences. That will be addressed in future versions of OpenStudio. The measure can be altered to show SI units instead.
- It is not possible to choose or define a refrigeration case (or walkin) re-stocking schedule in the "Grid" view or the "Layout" view; the drop down list is blank. [issue 966]
- Report web views may load slower than they use to with the update to Qt5. [issue 1211]
- With larger models, GridView's performance may slow. Performance improvements are currently being implemented and will be available soon in a minor release.

OpenStudio ParametricAnalysisTool
- NOTE: Cloud functionality is temporarily disabled. This issue is planned to be resolved shortly.
- NOTE: when using cloud service please make sure to stop the cloud using the cloud button in PAT when your simulation session is done, and after you have downloaded all of the detailed results you want. You are also strongly encouraged to go to the AWS Management Console to confirm that all instances are terminated. If they are not terminated, you will need to manually terminate them from the console. We have a sticky post on our forum with best practices for cloud simulation in OpenStudio.
- Daylighting control object variables can't be requested in the output variables tab. [issue 355]
- Adding a design alternative using measure groups will remove any design alternatives made from external files. However, you can add a design alternative made from external files without losing design alternatives made from measure groups. [issue 369]
- Always Run measures are applied to externally constructed design alternatives. This may result in unexpected results or errors. [issue 369]

OpenStudio ResultsViewer
- Alias changes do not update in table view until the data are read in again. [issue 25]
- Re-arranged column order doesn't stick next launch. [issue 30]

OpenStudio RunManager
- EnergyPlus ForwardTranslator errors do not appear in the RunManager GUI elements. [issue 181]

OpenStudio Platform, Including SWIG Bindings
- IdfObject::getQuantity and IdfObject::setQuantity functionality is not comprehensive. The quantity getters and setters for fields whose units are "BasedOnField AX" are not expected to work at the IdfObject level, but are to be handled only for OS: prefixed objects by the specific interfaces of classes derived from ModelObject.
- The default naming scheme of WorkspaceObject (base class for ModelObject, etc.) sometimes results in undesired name clashes when transferring objects between models, including in the EnergyPlus translators. Therefore, some objects may be unexpectedly renamed or copied.
- OpenStudio::Model::ComponentVector objects may be inaccessible from the Ruby bindings. [issue 239]
- If schedule type limits fields are not set properly, OS will not give error but also will not hook up affected schedules. [issue 967]
- There is no default construction for adiabatic surfaces. [issue 974]
- Cloning a building disconnects spaces from thermal zones. [issue 980]
- The simulation fails if ground preprocessor boundary conditions are used. [issue 1127]

Known Issues Specific to OS X
- The SketchUp Plug-in toolbar tooltips do not work correctly on OS X if you have made your toolbars horizontal. The tooltips never show on OS X in the status bar. The button state may also be incorrect. This is a bug in SketchUp versus the plug-in. [issue 45]
