Greetings Developers:
We are releasing an update to our API that may affect your application. Here's what's changing:
As described in our API documentation here:
http://developer.echonest.com/docs/v4/catalog.html#update
our catalog (a.k.a. Taste Profile) API has a documented limit of 100,000 items per taste profile. Although this is a documented limit, until today, this limit has never been enforced. Starting today we are enforcing this limit. This means if you try to add more than 100K items to a Taste Profile, the call will fail with an error. Taste Profiles that are already larger than 100K items will retain their full set of items, but you will not be able to add any more items to them. You may want to check your catalog update code to make sure that you handle this new behavior properly.
