I really don't understand why so many people are bashing Stardock over this one.
First and foremost, Stardock already did what they could when they partnered with Accuweather some time ago and *hosted* the weather feed themselves. This means Stardock is the company providing and paying for the bandwidth used by their Accuweather widgets, not Accuweather.
Second, DX widget authors are the *only* people responsible for choosing to use Weather.com over Accuweather.
Third, ALL applications using Weather.com's feed were affected, (and this is the important part) REGARDLESS of them following Weather.com's rules or not!!! Weather.com couldn't care less if you're one of the 'good' or the 'bad' guys, they knew this change would affect us ALL and they went ahead anyway!
Weather.com unilaterally and without warning CHANGED the format of the request string (they did the same last year, but at least then they sent out a warning before to everyone who had a valid license key).
Since most of us are using hard coded request strings (Winstep Xtreme included, but I changed that now) the only way to solve this is by issuing a new release. Fool me once...
