• Round frequency-axis labels in the spectrum and average plots according to
  tick spacing, keeping panned views readable while preserving precision at
  narrow zoom levels.
• Include changelog notes for versions skipped since the latest published stable
  release in stable and development GitHub release descriptions.

0.3.0 — 2026-10-09 — Waterfall navigation and faster analysis

• Parallelize independent FFT windows for exact minimaps, spectral averages,
  exact overviews, and larger previews/waterfalls with a bounded worker count.
  Preserve window-order reductions, cancellation, and progressive snapshots;
  keep small jobs and memory-heavy FFTs serial when appropriate.
• Show an animated status-bar spinner whenever background analysis, waterfall
  refinement, minimap filling, or exports are queued or running. Pointer-driven
  hover FFT updates do not trigger it.
• Add Settings → Waterfall rows to choose automatic display resolution or
  128–4096 rows, saved across launches and sessions and applied to detail and exact overviews.
  Honor explicit densities at large FFT sizes by allowing enough FFT work for the selected rows.
• Add a saved Display option to adapt waterfall colors on zoom or keep the
  current automatic color limits fixed across zoom, pan, and minimap navigation.
• Increase waterfall detail using physical viewport pixels and visible FFT bins,
  with bounded asynchronous refinement and explicit sampling/aggregation labels.
• Add a progressively populated whole-recording waterfall minimap with a movable
  viewport box and independently resizable top/bottom handles. Waterfall pan and
  zoom control the viewport independently of the analysis range; preserve frame
  measurements and freeze across refinement, and export actual viewport metadata.
• Add View → Dark theme to switch controls and dialogs between dark and light
  mode independently of the desktop theme. Save the choice across launches;
  analysis plots keep their existing colors without recomputing results.
• Hide the Baseband waveform panel by default. Enable it from View → Baseband
  waveform or run an Exact waveform analysis; saved workspace visibility is
  preserved.
• Add Help → Plot controls with spectrum, waterfall, and waveform gesture
  instructions in a dialog that can stay open while working. Remove plot hover
  tooltips and display waveform time-range labels to three decimal places.
• Align the average spectrum plot with the waterfall and keep its label and
  max-hold checkbox compact across window sizes and restored workspaces.
• Fix maximized floating panels retaining the mouse grab after a dock drag,
  keeping the rest of the application responsive.
• Open the CroccoSpectrum website from update notifications, and defer browser
  launch until the dialog is destroyed so Wayland can complete the request.
  Show a copyable URL if the browser launch request fails.
• Check for updates on every startup and announce an available version once per
  app session, including versions announced on previous launches. Continue to
  respect disabled automatic checks and GitHub retry limits.
