ATLAS Viewer Release: v11.5.2.537-W19#
This release adds a Recorder Connection Indicator improvement and resolves scatterplot session management, USB Logger stability, missing out-lap detection, and multi-session lap timing issues.
Evaluation Build Notice
This release is provided as an evaluation build, offering early access to a set of completed fixes and features ahead of a full production release. Evaluation builds are intended for validation and early feedback, and while the included changes are functionally complete, there may still be known limitations or issues that are addressed before the final release. We encourage users to report any problems or feedback encountered during evaluation, as this helps ensure the highest quality for the full release.
New Features#
Recorder Connection Indicator#
The recorder connection indicator has been enhanced to reflect the live link status of connected hardware units, giving users clear visual feedback on whether a recorder is connected and ready before recording begins.
The recorder border colour in the Session Browser, Recorder Editor, and Status toolbar now conveys both the recorder state and its link status:
| Recorder State | Link Status | Border Colour | Meaning |
|---|---|---|---|
| Idle | Link NOT OK | Orange | Recorder is waiting but has no active connection to the unit |
| Idle | Link OK | Green | Recorder is waiting with a confirmed connection to ADS or the unit |
| Monitor | Any | Dimmed | Recorder is in monitor mode |
| Recording | Any | Red (flashing) | Recorder is actively recording |
Additional behaviour introduced:
- Automatic stop on link loss — if a recorder loses its link while a manual recording is in progress, the recording is stopped automatically and an error message is shown.
- Invalid configuration detection — if a recorder remains Idle after an attempted state change and the link is not OK, an error is raised:
Recorder '{name}' Offlinefor Ethernet and DST recorders, or{name} configuration is invalidfor other types.
Auto-record behaviour is unaffected; link status is an additional informational layer only.
USB Logger Conversion Improvements (#7353)#
Improved the performance of the USB Logger Recorder when converting .bin files to .ssn2.
Bug Fixes#
Scatterplot Z‑Axis Colour Bar Missing#
Fixed an issue where scatterplots with a Z‑axis colour bar saved on a non‑active page would reopen without the colour bar once data had loaded; displays now initialise fully on page load without requiring a manual refresh.
Event Display Crash Due to Unsortable Header Columns (#7021)#
Fixed a crash that occurred when loading an event display with corrupted or invalid header column sort definitions.
USB Logger Recorder – Crash When Drive Is Unavailable#
Fixed a crash that occurred when USB Logger Recorder searched for files on a drive that no longer exists or has become inaccessible.
Statistics Calculation Failures in Waveform (#7082)#
Fixed an issue where ATLAS Statistics failed to display values for parameters in the Waveform display when any PDA (data provider) threw an exception.
Compressed Timeline and Incorrect Lap Times (#7293)#
Fixed an issue where, after several recordings, the timeline would become compressed with the current lap occupying the majority of the view and all previous laps squeezed to the left.
Incorrect Lap Timing and Naming in Stream Recorder#
Fixed an issue where lap state was not tracked per session, causing incorrect lap numbers and timing when multiple sessions were open simultaneously.
OwnerId Reset to Zero#
Fixed an issue where the OwnerId was being reset to 0 during App merge; the OwnerId is now correctly preserved.
Known Issues#
Stream Recorder doesn't rename final lap#
When using the ATLAS Stream Recorder, the final lap is not automatically renamed to "In Lap" after logging ends and stays as a numbered lap.
