+### 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.
+
+Remove one function (it will be recreated in the next step):
+
+```sql
+DROP FUNCTION create_country(hstore,character varying);

+
+Finally, update all SQL functions:

+./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
