Release 4.142 (5 Feb 2026)
====================
- RainViewer Radar is now gone :-( The service has been discontinued.
- NEW: Added low, mid and high cloud layers to the graph. This will default to total cloud data if cloud layers don't exist.
- If you prefer the total cloud layer, edit the graph and toggle the cloud elements.
- Improved OpenZones with automatic zones generated for storms. See side menu for OpenZones.
- Disabled radar for free users. I accidentally made it freely available.
- Major update to UI library.
- Improved loading of data and streamlines.
- Added Graph Editor option to add fixed data levels to graphs.
Bug Fixes:
- panning and timezones.
- map and graph mismatch.
- app opening to 00:00.
- daylight savings bug.
- PM2.5 air quality values in gauges.
- NOTE: RainViewer data will stop JAN 2026. See forum for more details.
