New Features: For the first time in a Mac weather application, view a custom-drawn surface analysis plotted on the radar and satellite map! The surface analysis (covering North America) shows current fronts and centers of high and low pressure and is natively drawn to any map zoom level. Enable this setting in the map's gear menu. Some other great new features include: • An option to show the first location's temperature in the Dock icon. • A new probability of precipitation graph. • A "Scroll to Now" button in the graph settings. • The graph scroll position is now saved to the settings and restored at the next application launch. • The text on the map is now outlined black so it's readable over snowy terrain. • HiDPI support. Bug Fixes: • Adjusted the resolution thresholds on the radar images so they look nicer at certain zoom levels. • The radar image time in the map settings now shows the time the radar image was generated, not the time it was last downloaded. • Check to make sure observed dew points are less than temperatures before displaying them. • Made several areas of the code more robust when running in parallel. • Make sure all observations database connections are closed before allowing the app to quit. • Fixed a bug when detecting precipitation type from a METAR. • Fixed a bug in the relative humidity calculation. • Fixed a bug where old forecasts could remain in the cache. • Fixed a bug where some locations in South America would incorrectly show sand in the current conditions. • Fixed a bug where some wind speeds would show n-n mph when n was the same value. • Fixed a formatting bug in the visibility strings. • Fixed a bug where if past graph data was missing and the forecast scrolls of the graph, then data would never be loaded. • Fixed a bug where forecasted values would sometimes show up on the graphs even if the time period had already passed. • Fixed a bug that resulted in some images displaying upside-down. • Fixed the animation curve when moving between cities on the map that are close to each other (less bounciness). • Fix a bug in the graph display when dew point temperatures are missing. • Fixed a bug where adding a custom location wouldn't load the graph data automatically. • Fixed a localization decimal bug in latitude/longitude fields. • Fixed a bug in the map code when running on displays that don't support 3D acceleration. • Fixed a bug that would cause the radar image to not update when the animation was paused. • Fixed a bug when there weren't enough graphs to cause the display to scroll. • Added locations in British Columbia, the Netherlands, Australia, and the British Virgin Islands. • Fixed the Athens, Greece and Burbank, CA locations.

• Moved the play/pause button for the map out onto the map (lower left corner). • Pressing the spacebar will now play/pause the map. • Moved the location info panel into a new location inspector HUD. • Several new locations and corrections worldwide. • Updated old US time zones to the appropriately named new ones. • Spaced the graphs apart a little bit more so they are easier to distinguish. • Made the weather database update code much more reliable. • Fixed a bug where the app would wipe out configured locations if the app quit before completing the initial setup. • Fixed an incompatibility with the nVidia 7300 and 7600 graphics cards. • Fixed a bug causing the current conditions wind direction arrow to be drawn in the wrong direction. • Fixed a bug where resizing the window to be really small and then back would mess up the graph display. • Fixed a bug where localized decimals were not being accepted in latitude/longitude fields. • Fixed a bug causing the last updated string to be updated every minute instead of just during an update. What's new in Seasonality Core 2: • New maps with changing terrain each month. • Higher resolution radar and satellite imagery with animation. • Graphs for liquid precipitation, snow amounts, cloud cover, and even wave height in supported locations. • New 7 day forecast with improved legibility and new icons. • New current conditions view. • Full screen and gesture support in Lion. • Several other features and bug fixes, too numerous to name…

Some users are seeing a "hash mismatch" error while upgrading Seasonality. This is a bug in Apple's App Store app and has been fixed in Lion 10.7.2. Please use Software Update to upgrade to 10.7.2 and then try the Seasonality Core upgrade again. Overview Seasonality Core 2.0 is a major new release with new features in just about every part of the application. The map generator has been completely rewritten using higher resolution maps with animation and dynamic terrain. Significant improvements to the graphs are also included, with 7 day hourly forecasts plotted and entirely new graphs for liquid precipitation, snow amounts, cloud cover, and wave height. This release also includes a new application icon, new weather forecast icons, full screen support on Lion, a new current conditions view, and an optimized 2nd generation weather back-end among many other improvements. View a complete list of improvements below. Maps • New map terrain with over 2 gigapixels of resolution. • Support for dynamic terrain. Terrain images change every month of the year, so you can watch the foliage change and snow line move throughout the seasons. • Support for animated radar/satellite imagery and control over animation duration and speed. • Powerful new mapping framework that uses multiple processors to render as efficiently as possible. • The map view can now be maximized to take the full area of the window. Graphs • New graphing framework with improved graph look and performance. • Added graphs for liquid precipitation, snow amounts, cloud cover, and wave height. • 7 day hour-by-hour forecasts added to most graphs. • New graph hover showing exact graph values in a bubble. • Added status overlays to the graphs. • The graph view can now be maximized to take the full area of the window. Forecast • New forecast layout that is more readable. • New weather icons. • Forecast data is now cached for quick display when the app is first launched. Back-end Data and Locations • Pre-index the location database, so no long waits the first time launching a new update of Seasonality. • Switch the weather and location databases to SQLite 3. • Improved the speed and fixed bugs in the METAR decoder. • Update locations in Serbia, Montenegro, Yosemite, & Berlin. Lion • Fullscreen support on Lion! • Added gesture support for the graphs and radar/satellite imagery (pinch to zoom and pan). User Interface Improvements • Adjusted the text colors and fonts to make things easier to read. • Optimized the location table to be more readable. • Removed borders from the modules to make them look cleaner on screen. • Darkened the blue heading color. • Changed the colors used in the graph settings to better match the new UI. Preferences • New graph and map settings interfaces. • Automatically close the graph/map view settings if the user clicks in another area of the window. • Removed extra units strings from the preferences to make it easier to read. • Added height units to the preferences. General Improvements • Changed the name of the app to Seasonality Core. • New application icon. • Added a new current condition view across the top of the window. • Added a Last Updated line to the bottom of the window (click to reload data). • Optimized the launch speed of the app. Will now launch in one bounce and update as modules become available.
