The NWWS-OI Era · 2026
v0.0.63 Latest October 11, 2026

The Streamer Update: a new live radar warnings map, a full set of redesigned stream overlays, and tools built for storm streamers.

What's New
  • Radar Spotlight: The Warnings tab is now a live radar map with every active warning drawn on top. It auto-jumps to each new warning, offers General, Detailed, Velocity or no radar, and can be popped out or docked beside any other tab.
  • Watches, MCDs and SPC Outlooks: A new polygon style with an optional radar layer, plus fixed lag when zooming in close.
  • Alert Map Radar: The alert card map can now switch between Composite, Reflectivity and Velocity radar.
  • Storm Arrival Times: Warnings with a storm motion show which towns are in the path and when the storm should arrive, on alert cards, notifications, stream popups and the Streamer Remote.
  • Streamer Remote: A control panel for your stream: pause popups, map auto-jump and the Emergency Takeover, spotlight, re-announce or hide alerts, post a breaking banner, and more. It can sit in a tab, float, or dock to the side.
  • Full Stream Overlay: A complete broadcast layout in a single OBS source, with slots for radar, facecam and extra cameras, a built-in alert map, counts, SPC risk, popups, ticker and clock. The frame takes the color of the highest active alert. Includes optional socials, layout options, placement guides and a Reset to Default button.
  • New Stream Overlays: Emergency Takeover, SPC Risk widget, Sponsors, Socials, and Radar Spotlight as a stream overlay.
  • Redesigned Overlays and Notifications: Every stream overlay was rebuilt with the new look and loads reliably in OBS. In-app notifications gain a mini map, tags, expiry and arrival times, and the Alert Ticker has a custom bar height.
  • Test Alerts: Injected test alerts are never saved and are cleared from your stream on logout. A new "Send on alert map" option controls whether a test alert moves your stream map.
Fixes and Improvements
  • Overlay Warnings After Restart: Fixed stream overlays losing active warnings after restarting the app.
  • Jump to Card: Fixed Jump to Card not working for real alerts.
  • Radar Fixes: Fixed radar not returning after switching modes, a faint composite showing behind Detailed radar, and a square glow around warnings when zoomed out.
  • Streamer Remote and Sponsors: Fixed the sponsor card being cut off and spotlighting real alerts from the Streamer Remote.
v0.0.60 October 10, 2026

A major update featuring an overhauled stream elements system, reworked cloud services, custom audio volume management, a remade notification system, new sounds, a new Watch tab, a draggable and expandable alert popup map, and a new generic installer with in-app update banners.

What's New
  • Stream Elements Overhaul: Stream elements have been rebuilt from the ground up for cleaner, more reliable broadcast overlays.
  • Cloud Services Rework: Cloud services that use custom settings have been completely reworked.
  • Custom Audio Volume Management: Set and manage audio volume to your liking with new custom controls.
  • Remade Notification System: Notifications have been rebuilt for more dependable, clearer alerting.
  • New Sounds: A fresh set of alert sounds.
  • Active Alerts While Away: Alerts that are still active now appear even if the app was closed when they were issued, so you never miss what happened while you were away.
  • Alert Popup Map: The alert popup map now works across tabs and can be dragged and expanded.
  • New Watch Tab: Watches now have their own tab and alert cards, separating them from warnings.
  • Generic Installer with In-App Updates: A new generic installer means future updates no longer need a fresh download. When a new version is out, a banner appears automatically in the app and you update right from there.

v0.0.52 September 25, 2026

A small map patch swapping in a new tile provider after the previous one changed its free-tier usage policy.

Fixes and Improvements
  • Map Tile Source: Switched to a new map tile provider after the previous free provider changed its usage policy. No other changes in this release.
v0.0.51 Beta August 9, 2026

A performance and infrastructure patch headlined by a new dedicated relay server for a stable, 24/7 Central Feed connection, alongside large performance upgrades and reduced storage requirements across the app.

What's New
  • New Relay Server: Central Feed now runs through a new dedicated relay server built for 24/7 uptime, delivering a far more stable connection with fewer drops and reconnects.
v0.0.51 or higher is required to use Central Feed. The new relay server replaces the old one, so builds prior to v0.0.51 can no longer connect to Central Feed. Update here if you are on an older version.
Fixes and Improvements
  • Performance Upgrades: Large performance improvements throughout the app for smoother, faster day-to-day operation.
  • Reduced Storage Requirements: Cut down the app's on-disk footprint significantly.
v0.0.5 Beta July 16, 2026

A data and routing release headlined by the new MCD Archive tab and Discord webhook alerts, alongside a deeper SPC Archive, a new Glass theme, and major connection fixes.

What's New
  • MCD Archive Tab: A dedicated tab for pulling up past Mesoscale Convective Discussions by date, with the full discussion text and its associated graphic, bringing MCDs in line with the existing SPC outlook archive.
  • Discord Webhook Alerts: Route live alerts straight out of StormSync into any Discord channel through a configurable webhook. Pick which alert types get forwarded, and your server is notified the moment a warning is issued.
  • SPC Archive Expansion: Historical convective outlook retrieval now reaches back to 2003, up from October 2019.
  • New Glass Theme: A translucent, layered interface theme built to match the website's design language, selectable alongside the existing themes in settings.
Fixes and Improvements
  • Central Feed Reliability: Repaired the issues that were causing Central Feed to stall or drop alerts. Relayed alerts now arrive consistently.
  • Private Account Freezes: Fixed the sudden freezes that could occur while connected with your own NWWS-OI credentials.
  • Stream Tab: Temporarily disabled while its elements are reworked. It returns in the next patch.
v0.0.4 Beta June 25, 2026

A major access update headlined by Central NWWS-OI Mode, alongside a new Stream tab, an expanded SPC Archive, and a refreshed settings panel.

What's New
  • Central NWWS-OI Mode: A new connection mode that lets anyone receive instant NWWS-OI alerts without needing their own NWWS-OI credentials, removing the single biggest barrier to entry.
  • Stream Tab: A dedicated tab introducing three new stream elements for use with broadcasting software, alongside major fixes to existing ones. More fixes and additions are planned with every upcoming patch.
  • GUI Color Refresh: Interface colors updated to better match the website's design language.
  • New Settings: Enable notifications individually for every type of severe alert, and assign sound effects across the board.
