The change to 5.0 changes from drawing the weather graphics on canvas elements and instead uses HTML and CSS to style all of the weather graphics. A lot of other changes and fixes were implemented at the same time.
* Replace all canvas elements with HTML and CSS
* City and airport names are better parsed to only show the city name.
* City and airport names are better parsed to better show location in the available space
* Remove the dependency on libgif-js
* Use browser for text wrapping where necessary
* Some new weather icons
* Refresh only on slideshow repeat
* Removed Almanac 30-day outlook
* Fixed startup issue when current conditions are unavailable
*
## Why the fork?
