The old API (1.0) will be shut down on December 15!
It looks like the API-List of all releases by one artist, which dano's and my scripts use, will not work with the new API (2.0).
The new version lists only the master releases when more then one versions of a release exist. And this master release has unfortunately only one release id, the other versions are missing.
Releases with only one version are still all displayed. But these come now without the album artist.
Have a look a these links:
Normal Artist page:
http://www.discogs.com/artist/Lester+Jones
Old API Artist page:
http://www.discogs.com/artist/Lester+Jones..._key=41e338cd4e
New API Artist page:
http://api.discogs.com/artist/Lester+Jones...&releases=1
Notice the second release "Kurbel Compilation 4". In the old API it had two entries for every version. In the new one, there is only one entry for the master release with a id of the main release.
