Page 6 of the new Seafarers rulebook states:
"A general note on Catan rules. This is the 5th English-language edition of Catan Seafarers. Over the years, the rules have been clarified, refined, and occasionally updated. As of January 1, 2015, all of the rules in this version of Catan take precedence over any previously-published rules."
Is this notice simply a formality for the 5th edition release, or is there actually something that was changed, refined, clarified? (And I ask regarding any of the expansions, not just this one.) Because I can't find what it is.
Also, does anyone know if any of the default map layouts changed?
