+Refreshed correlation sets and data sources including updating to 2019
+US Census locations and incorporating public domain airport information
+from the wonderful ourairports.com community, stopped using the long
+defunct metar.tbl and zonecatalog.curr.tar files, switched to HTTPS
+protocol since all the URLs had started redirecting from HTTP to HTTPS
+anyway, added functionality for fetching forecasts from HTML pages where
+they're wrapped in preformat tags and included a new forecast zone for
+the Hong Kong Observatory using this, fixed a few bugs when running
+under recent Python 3 versions.
