v2.0.1

NexView v2.0.1 — Performance Edition

New Features

• Multi-radar group animation — Ctrl+Click radars to add to group, synced loop animation across all active radars with parallel S3 download
• Composite GIF export — Export multi-radar groups as composited GIF animations (1920x1080)
• Bilinear interpolation renderer — GR2Analyst-quality smooth rendering with gate and azimuth interpolation
• Dynamic resolution scaling — Render resolution adapts to zoom level (1024/2048/4096px)
• 3D cross-section view — Perspective-projected vertical cross-section with drag-to-rotate, ground plane grid
• Custom color tables — Load GR2Analyst (.pal) and RadarScope color table formats, 6 built-in presets

v1.5.1

NexView v1.5.1

Bug Fixes

• Sounding render freeze fixed — Root cause: pressure loops in Skew-T renderer got stuck at floor value forever (p.max(P_TOP) = infinite loop). Now terminates correctly.
• HRRR soundings re-enabled — Click anywhere in CONUS for HRRR model sounding with 30s timeout, falls back to IEM/rucsoundings
• CIN clamped — CIN values capped at -2000 J/kg to prevent absurd numbers
• Drawing safety — NaN guards on all line-drawing functions, Bresenham length caps, moist lapse rate safe defaults

v1.5.0

NexView v1.5.0

New Features

• HRRR model soundings — Click anywhere in CONUS for a full sounding with SHARPpy-equivalent parameter computation (CAPE/CIN, STP, SCP, SHIP, Bunkers, SRH, etc.)
• HRRR map overlay — View HRRR weather model data (reflectivity, 2m temp, wind, precip, and more) directly in the radar viewer
• Bundled basemap — No internet needed for map tiles, just extract and run

Bug Fixes

• Sounding freeze fix — NaN guards and iteration limits prevent infinite loops in CAPE/CIN computation
• Sounding timeout — HRRR sounding fetch capped at 30 seconds with proper fallback to IEM/rucsoundings
• Basemap visibility — Map borders and coastlines now render on top of all weather data layers

Bug Fixes

• Sounding crash fix — Skew-T renderer no longer crashes the app on bad data
• Super-res tilt filtering — Only valid tilts shown for super-res products
• GPU rendering defaults to off — CPU+Rayon is faster

v1.3.0

NexView v1.3.0

New Features

• Settings window - Gear icon opens full settings panel with opacity controls, overlay toggles, GPU rendering toggle, default station config, and GIF export
• Warning opacity slider - Adjustable opacity for NWS warning polygons
• GIF export in toolbar - Quick-access GIF button appears when animation frames are loaded

Fixes

• GPU rendering on Windows - Dedicated wgpu device for compute prevents display pipeline interference. Falls back to CPU if GPU output is empty.
• Sounding freeze - Drop guard ensures fetch flag is always cleared, even on task panic

Previous (v1.2.0)

• Multi-radar support (Shift+Click)
• GPU rendering on macOS (Metal Rgba8Uint)
• NWS polygon alignment fix
• 19 bug fixes

v1.2.0

NexView v1.2.0

New Features

• Multi-radar support - Shift+Click any radar station to load multiple radars simultaneously on the map. All radars render at their geographic positions. Cyan chips in toolbar show loaded secondaries with remove buttons.

Fixes

• GPU rendering on macOS - Fixed Metal compatibility by using Rgba8Uint storage texture format
• NWS warning polygon alignment - Fixed south/east offset caused by Mercator projection nonlinearity in radar image positioning
• Warning polygons in quad mode - Polygons now render in all quad panes
• Dual/quad mutual exclusivity - Can no longer have both modes active simultaneously
• 19 bug fixes from v1.1.1 (SRV computation, sounding freeze, memory leaks, etc.)

v1.1.1

NexView v1.1.1

Bug Fixes (19 fixes)

• Fixed sounding mode freeze - NaN data caused async task panic, leaving fetching flag stuck (infinite spinner + 100% CPU)
• Fixed critical SRV (Storm Relative Velocity) computation - was subtracting knots from m/s, off by ~1.94x
• Fixed crash on volume scans without reflectivity data - graceful handling instead of panic
• Fixed GPU rendering - now defaults to wgpu backend with GPU enabled by default
• Fixed unbounded memory growth - map tile cache (500 max) and site cache (20 max) with LRU eviction
• Fixed potential deadlock in map tile provider switching
• Fixed cross-section clipping values above color table max
• Fixed color legend using premultiplied alpha incorrectly
• Fixed GIF export frame delay rounding
• Fixed velocity display units for SRV product
• Fixed wall mode crash on missing fetcher
• Fixed concurrent download race condition
• Fixed color table producing wrong colors for extreme values
• Fixed macOS Gatekeeper "damaged app" error with ad-hoc code signing
• Various other stability improvements
