Tonight we are pushing an update of our V4 beta APIs at beta.developer.echonest.com. This is major milestone - the V4 APIs now implement all V3 functionality (along with much more). Here’s what’s new in this beta release:
* song/identify - Identifies a song given Echo Nest Musical Fingerpint hash codes.
* track methods - upload, analyze and profile - are now fully supported
* artist search - now supports extended constraints and sorts, query by description
* artist similarity - now supports extended constraints and sorts
* more artist data - like top terms (still very much in beta)
* improved song search (with super powerful boosting)
* Data Feeds - we’ve got rss feeds for everything
There are updates to our client libraries to support all the new features: beta_pyechonest and jEN.
