All the changes (that I could remember) are listed below:

• Hyperlinked and bookmarked the PDFs
• Justified text throughout 
• Revised prose for coherence, grammar, general flow, etc.
• Moved starting clues to the quest-giver table on p. 2
• Added slightly more details to keyed locations on p. 6 (emphasis on slightly)
• Upscaled Faction Relations chart to take up a full two-page spread (p. 9-10) 
• Fleshed out a description of the "Silver Pool" encounter on p. 12
• Added provision to give Wardens more room for providing clues (p. 17)
• Revised Clues (p. 17) and spread them out farther across the map
• Condensed Rival Parties (p. 18) to a single page and changed part of the rival party procedure to take place in between sessions
• Moved NPC tables (Knights of Prytania, Roll-a-Bandit, Roll-a-Fairy)  to p. 19 and rewrote a few entries to better match the setting
• Changed the Lost Pride side-quest (p. 22) so that Dojn Dugal gives players the tracker's tongue as an advance for taking the job
• Revamped adventure site encounter tables 
• Tweaked logic and added slightly more details to each of the adventure sites (emphasis on slightly)
  • 1 exciting example---I incorporated the shiny fruit from the illustration into the text
• Changed the logger ants to "crofter ants," mostly the same with some different behaviors
• Adjusted diredew's function as a "trap" and added some detail to make it stand out from the other carnivorous plants in the book

P.S. There's been some interest in print copies of WOTWW. I hope to find a good merch option to sell them online in the new year!
