Vicon Evoke 1.7.1 and 1.7 resolve a number of issues, including the following selection.

## Addressed issues in Vicon Evoke 1.7.1

- Fixed crash when repeatedly setting a system frame rate lower than 50Hz then above 50Hz (50Hz is the minimum frame rate supported by Active Wand)
- Fixed rare crash when loading tracking configuration or importing subjects via API
- Fixed unlabeled reconstruction datastream output always being enabled in Evoke Headless
- Fixed ‘F2’ key to rename a subject not working on assigned objects
- Fixed API RadioDeviceServices.WarningsChangedCallback not triggering after first change, or when warnings are cleared
- Fixed API RadioDeviceServices.Warnings returning Result.NotFound when there's no warnings for a device - this is now only returned if the device is not present in the system
- API RadioDeviceServices.SetRadioChannel no longer accepts unsupported channel values

## Addressed issues in Vicon Evoke 1.7

- Empty character slots are now renamed when the character is renamed. The cursor selection and hover highlight work as expected after renaming also.
- Loading tracking config files, with empty characters present, now works as expected.
- Reconstruction Graph Plots no longer take up excessive disk space for large captures.
- The API install script runs as expected for all Windows display languages.
- Smart objects with names that differ using '0' characters (for example, 'Smart Object 1', 'Smart Object 01', 'Smart Object 001') all have unique patterns assigned to them.
- Loading a camera calibration from an .mcp file now creates a *LatestCalibration.xcp* file and the loaded calibration is restored after restarting the application.
- The command-line option `--force-gles` is no longer supported and has been removed.
