[0.1.7] - 2026-05-14

Auto-detect and ROI improvements

  • Overhauled the auto-detect window with a dual-pane overview/detail timeline, interactive ROI selection, grid opacity control, and per-cell border rendering for clearer event visualization.
  • Added incremental algorithm rerun scheduling so parameter changes (scale, opacity, ROI) trigger a debounced re-evaluation without blocking the UI.
  • Active-cell overlay and cell-border rendering are now cached by pipeline generation, avoiding redundant recomputation across frame scrubs.
  • Exporter now selects ROI-scoped speed metrics when an ROI is defined, falling back to full-frame metrics otherwise.

Performance

  • Added DownsampledFrameSource (sdapp/shared/frame_source/downsampled.py) and compute_visualization_stats_for_preview to compute visualization stats at 0.25× resolution during the analysis-launch preview, then upsample the baseline back to full resolution — significantly reducing preview wait time on large stacks.
  • Added sdapp/shared/diagnostics/ with OpenPerfTrace: a lightweight wall-clock stage/mark tracer for the analysis-window open path. Traces are dumped to the app log on completion and silently discarded on failure.
  • Analysis launch flow now wraps the full open sequence in a perf trace, attributing time to import, preview preparation, frame rendering, and options-dialog interactions.

Model/checkpoint compatibility

  • No checkpoint format or project schema bump in this release; existing managed and local SAM2 model selections remain compatible.

Platform/backend limitations

  • No platform-specific regressions are known from the automated suite.
  • DC trace controller and host window controller received minor fixes to align with the updated auto-detect and analysis launch flows.

.sdproj/migration notes

  • No .sdproj schema version bump is required; existing projects remain loadable.
  • _save_project_after_metrics_apply now persists project state immediately after metrics are applied from the host window, reducing the chance of unsaved metric changes.

Known segmentation caveats/regressions

  • No new release-blocking segmentation regressions are known from the automated suite (708 tests pass).
  • SAM2 post-processing/native extension availability may still vary by environment.
  • Auto-update behavior still depends on platform packaging/signing state; validate against final signed release artifacts.
