LXEdge Version 1.5.0
Released: June 12, 2026
Major Updates
- Implement updated feature extraction for OSS-3 scoring.
- Allow review of chart “As Recorded” or as dressed up by “Examiner” or “Reviewer”. User can toggle among the various profiles.
- Significant changes to settings. Most notably, the “Chart” settings tab has been reorganized into “Chart Recording” and “Chart Appearance” tabs.
- Significant behind-the-scenes improvements related to settings.
Minor Updates
- Changes related to windows used to record or review video associated with chart:
- Make smaller by default, with ability to resize
- Always keep in front
- Allow window used to review media outside a chart to be resized
- Make thinner the lines used to indicate response and beginning and end of response onset window.
- Added white as an option to primary color picker.
- Remove the “More” button from the color picker.
- Add “Custom” question set type that should be used when none of the available question set types are appropriate. Replace “None” question set type with indication that user should select a valid question set type.
- Refine the appearance of the question label that appears inside chart by removing the box and increasing the range of the Question Label Font Size setting.
- Move setting to shrink chart to fit on a single page when printing to the System settings tab. Removed the Print setting tab.
- Added the ability to modify hotkeys related to running a chart to the Chart Recording tab.
- Modify implementation of “Very Low” audio setting so that post-conversion is no longer needed. This allows the LXEdge installer and footprint to be significantly smaller.
- Allow import of some older NCCA export files with non-numeric exam or chart numbers.
- Modify so simulator only creates data when needed behind the scenes. Slightly improves software performance.
Bug Fixes
- Navigating away from a chart while a note with unsaved changes was open would cause all sensor data to be lost for the chart.
- Charts would fail to load when .lxw file is corrupted in a certain way (missing File Reference).
- Two cameras of the same make and model could not be used at the same time.
- Import would fail for NCCA files with extremely low data rates.
- Software would crash when attempting to NCCA export a chart that had been created using NCCA import.
- Traces would not appear in imported charts for completely flatlined data in NCCA files.
- Charts with rare unusual traces would cause OSS-3 scoring to fail.
- Response Onset Window line widths would change with zoom level.
- Data rate was incorrect in NCCA export of charts created using Simulator.
- NCCA import would fail for files with unexpected label for Sample Rate.
- Memory usage by LXEdge would increase substantially over time while running and/or reviewing charts; this usage has been reduced significantly. Issues associated with the high memory usage included:
- Short segments of dropped data in charts
- Decreasingly responsive software performance, to the point the software was unusable
- LXEdge would crash when attempting to open a report that contains merge fields not found in the associated Personal History or Series information.
- In rare cases, failure of audio/video recording would result in empty recording files, even though recordings appeared to be working as expected.
- In rare cases, PF could be corrupted when a recording split occurred while recording audio in “Very Low” mode.
