DG have a new website, and it is a poor substitute for what was there before.
Instead of the familiar RESTful URLs to find a release from its catalog number (ex: https://www.deutschegrammophon.com/cat/4796038) the release now has a words-plus-a-few-digits identifier (ex: https://www.deutschegrammophon.com/catalogue/products/tchaikovsky-sibelius-batiashvili-5292) which does not seem to be deterministic. So all our links into the catalog are broken and probably unfixable.
Moreover, even once you have found the entry you want, the information is much more limited. You still get the performers on each track, but not the date and place of recording or the engineers and producers.
Obviously the import-from-DG script no longer works.
At the time of writing, the Decca catalog, which to a large extent duplicates the DG one, still presents the old interface (ex: https://www.deccaclassics.com/cat/4796038). It would be therefore be possible to change the links from MBz to refer to the Decca catalogue instead, Who knows how long that will last though?
