What's new in 3.5.1
- Storm reports in Live Tracking: show tornado, hail and wind reports beside
radar and alerts, with hazard filters, event windows, hover details and past-hour
caching and playback.
- Correct supplemental radar times: use the published observation times for
SAILS and MRLE products, avoiding false future-scan failures.
- Clear overlay recovery: distinguish unavailable radar scans and uncached
alert history from connection or decoding failures, with Return to Live for
missing historical frames.
- Faster first sounding display: ECAPE now uses a native Rust workspace,
reducing first-render delay and initial memory use while preserving scientific
reference checks and missing-data behavior. In the recorded local UHD comparison,
the first-render median improved from 5.15 s to 3.37 s with about 160 MiB less
initial peak working set; repeated-render timings were essentially unchanged.
See the measurement report for the
hardware, comparison method and limits. This patch also includes the public-updater
acceptance check for the existing install review.
Included from 3.5.0
- Australian radar: search 67 sites and view MRRL Base Reflectivity or
Doppler Velocity, with actual scan times and distinct range-folded values.
- Updraft tracks: view 1-hour and 3-hour maximum updraft helicity for
2–5 km AGL on HRRR and supporting models, with a shared colour table.
- Map details: toggle OpenStreetMap roads per panel, read full storm-report
hazard names and use consistent surface-station symbols.
- Sounding controls: pick sources and forecast times in compact glass
popups, switch chart panels, and edit one level at a time with undo/redo.
This release includes the Rust migration baseline
for downloads, live providers, map processing and sounding calculations.
Weather analysis
- Model Viewer: compare forecast fields in one, two or four synchronized
maps. Models are grouped into CONUS, Global and Regional, with NAM and RAP
under Regional. Parameter choices follow the selected run's published fields.
- More model coverage: explore supported GFS, ECMWF, ECMWF 9km, NAM and HRW
parameters. GDPS provides point soundings; AIGFS provides map analysis only.
- Live Tracking: follow radar, satellite imagery, surface observations,
warnings and watches. Compare available radar products and tilts, inspect
measured values and replay cached observations with their source times.
- Soundings: open observed, model or ERA5 profiles, or import local files.
Inspect linked Skew-T and hodograph levels, edit a profile with undo/redo,
and copy or export HD/UHD PNGs with edited-level annotations.
Clearer controls
Find parameters by category or search, preview descriptions in a separate glass
card, and switch between navigation and point inspection beside playback.
Readable glass readouts follow saved temperature and wind units. Graphics
settings compare Automatic, Low, Balanced and High in one view.
Logs can copy a diagnostic summary with the operation, provider, time, error
category and recovery action, excluding credentials and raw request details.
Before an update installs, review which preferences and caches remain and which
open soundings, edits and history will be lost.

Get started
Windows installers and portable ZIPs are distributed through
GitHub Releases.
Both include the analysis backend and Python. Extract the complete portable
folder before launching it. Existing installations can check Settings →
Updates. Release assets include checksums and build provenance; the Windows
