     - ESRI mapping interface has been upgraded from 3.x to 4.x (3.x is being retired soon).
     - When adding points of interest, converting a street address to a geographic location is no longer possible because ESRI has blocked remote public access to the online resource needed to perform this operation. As such, this feature had to be removed.

     - Help graphics and Point Of Interest Tutorial graphics have been updated.
     - Error messages are no longer blocked by the full map.
     - Data requests are now processed individually rather than in bulk. If one request produces an error, the webpage will process whatever data was obtained and display a notice next to what wasn't updated.

     - Added a utility section to the main page, which allows users to remotely query technical forecast discussions. This is primarily intended for meteorological use, but is available to anyone.
     - A minor issue occurred when an improperly formatted severe thunderstorm warning was recently issued. The text parsing algorithm has been made more robust incase this happens again.
     - Fixed an intermittent bug that could arise when odd behavior occurred with SPC-related data on the full map.


-- 6/21/2021 Beta 0.8.6
     - Adjusted text parsing algorithm to accommodate a recent change made to NOAA's servers.

     - For the panel that appears when new SPC products are detected, the top button now says "Open Map" instead of "View On Map".
     - Fixed a bug that would prevent mesoscale discussions from being processed correctly if a public severe weather outlook was in effect (don't ask me why this needed to be "fixed").
     - If storm tracks are enabled on the full map, toggling the severe thunderstorm warning layer should no longer leave behind an errant line (this only occurred if a warning was for a line of storms).


-- 2/19/2021 Beta 0.8.1
     - Storm reports that occur in Gulf of Mexico Zones (GMZs) are now more properly presented.

     - Fixed a bug that would cause a display issue and an incorrect sound to play if an "Evacuation Immediate" alert was issued on the Virtual Weather Radio.
     - If the possibility of a tornado is mentioned in the hazard section of a severe thunderstorm warning, the one-line summary should no longer display redundant information (i.e. it should no longer say something like "Quarter size hail with an enhanced risk of a brief tornado and a possible tornado").


-- 3/21/2020 Beta 0.7.5
     - When the individual polygon of a warning is being viewed, selecting a different warning while the map is still visible will no longer cause a confusing display issue.
