+### New Wikipedia/Wikidata importance tables
+
+The `wikipedia_*` tables have a new format that also includes references to
+Wikidata. You need to update the computation functions and the tables as
+follows:
+
+ * download the new Wikipedia tables as described in the import section
+ * reimport the tables: `./utils/setup.php --import-wikipedia-articles`
+ * update the functions: `./utils/setup.php --create-functions --enable-diff-updates`
+ * compute importance: `./utils/update.php --recompute-importance`
+
+The last step takes about 10 hours on the full planet.
