By popular demand, I've added a "wind direction indicator" option that you can turn ON/OFF in the "Other" tab. Some found it hard to look up to the top of the mast to see the indicator. Download the latest Version 2.81 and enjoy!
BTW: what changed...you may ask? You can always check this link to see a fairly detailed log and history: Latest Changes you can also see this from within the program using the menu option Help / What Changed?
