v0.4.0

Stable release

Version: 0.4.0

CI run: https://github.com/gioeleminardi/CroccoSpectrum/actions/runs/38302810241

• Shorten the waveform scan button and menu action to Exact Waveform. Add
  independent mouse-wheel waveform zoom and drag panning down to single samples,
  with connected I/Q traces and sample markers. Waterfall time navigation resets
  waveform zoom; Exact Waveform scans its current visible interval.
• Synchronize waveform time bounds with the waterfall viewport through full views,
  zoom, pan, and minimap navigation. Distribute the bounded waveform preview across
  the visible interval, label sampled coverage, and keep hover from replacing it
  with a local interval. Exact waveform scans the visible waterfall interval.
• Separate waterfall wheel zoom: scroll to zoom only time, or Ctrl + scroll to
  zoom only frequency around the pointer.
• Rework Time selection into a compact Analysis interval section for exact frame
  entry, averages, and sample exports. Remove the duplicate timeline
  and zoom buttons; Use waterfall view applies the minimap's visible interval.
  Move precise time seeking to View → Seek to time.

v0.3.1

Stable release

Version: 0.3.1
Commit: 84f4f83
Build date: 2026-10-09T17:41:54Z
CI run: https://github.com/gioeleminardi/CroccoSpectrum/actions/runs/37968010875

• 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.

v0.2.0

Stable release

Version: 0.2.0
Commit: f8fe621
Build date: 2026-10-09T13:10:20Z
CI run: https://github.com/gioeleminardi/CroccoSpectrum/actions/runs/37934867523

• Identify development builds with the planned release version, CI build number,
  and source commit in the application, exports, packages, and build manifests.
  Publish verified devel pushes as distinct GitHub prereleases and stable tags
  as releases after all packages, sources, and checksums are ready. Offer stable
  and development downloads separately on the website; development applications
  recognize the corresponding final stable release as an update.
• Add automatic stable-release checks and update notifications with a release
  page link for manual installation. Help actions check on demand or disable
  automatic checks; incomplete release uploads, offline failures, and rate
  limits are handled without interrupting analysis. Bundle Qt Network's TLS
  backend and OpenSSL runtime libraries in Linux packages.
• Add File → Open recent for the ten most recently opened recordings and
  sessions, with history saved across launches and a Clear recent files action.
  Metadata recordings reopen through their original metadata file.
• Automatically enable absolute-frequency display when opening or changing a
  recording interpretation with a known center frequency. Rename the display
  checkbox to Absolute frequency.
• Round spectrum crosshair frequency labels and cursor status readouts to the
  nearest whole Hz.
• Extend the spectrum's vertical frequency cursor through the waterfall to
  correlate signals across both plots. Keep it aligned during zooming and
  resizing, and clear it when the spectrum cursor disappears.
• Add mouse-wheel zoom around the pointer and left-drag pan for both frequency
  and time in the waterfall. Keep frequency navigation linked to the spectra
  and time navigation within the current preview, preserving measurements,
  click-to-freeze, and double-click seeking. Hold Ctrl when starting a drag to
  pan only time without changing the frequency range. For a selected recording
  slice, move the interval with its width fixed and update the Start/End fields
  live. Move cached rows immediately and refresh newly exposed data in the
  background while dragging, preserving frequency zoom and the active gesture.
  Clamp the interval to the recording bounds; whole-recording views pan preview
  rows instead.
• Complete spectrum and waterfall measurements with a plain left-click after
  Shift-clicking the start. Update plot hints and the keyboard shortcuts
  cheatsheet to describe the gesture.
