Note: This patch was made available on NI Update Service.
| ID | Description |
| 610384 | .NET methods are not available if a .NET class uses a 64-bit enum. |

| 710211 | LabVIEW can crash when you drag nodes out of a Flat Sequence structure. |
| 710323 | LabVIEW can appear to hang when loading a VI that contains a variant on its front panel when that variant contains a large number of variant attributes. |
| 710553 | Saving a copy of a typedef takes longer than expected. |
| 711411 | LabVIEW edit-time performance is severely reduced when you edit large tabs after performing the maximum number of undo steps. |
| 714264 | LabVIEW can crash when you drag structures out of a Flat Sequence structure. |

| 714945 | (macOS and Linux) Help documentation is missing for many LabVIEW properties. |
| 715018 | In rare cases, VIs can be saved into a bad state which causes LabVIEW (32-bit) to crash when running the VIs. |
| 715178 | Reduced the overhead for drawing images and text on Windows 10. This was most noticeable when there were many different controls with text and/or images to draw. |
| 715347 | Reduced the overhead for updating front panel controls with new data from the block diagram. This was most noticeable for applications with a large number of VIs. |
