   to easily add Senses to Lexemes, has lately been improved significantly
   - 33,000 values of British Museum person or institution ID (P1711)
   <https://www.wikidata.org/wiki/Property:P1711> now have a useful target
   again. After their being mostly inoperative for several years, the new
   British Museum website now has information pages matching these values,
   with links to related objects. (Example
   <https://www.britishmuseum.org/collection/term/BIOG43386>). To work
   around bug T112081 <https://phabricator.wikimedia.org/T112081>, a script
   by Andrew Gray is going through the items making null edits to update the
   relevant URLs.
   - Outdated copy of wb_terms has been dropped on April 29th
