+=== Important pre-upgrade notes for 1.31 ===
+* If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply

+  to the ar_text and ar_flags columns of the archive table or make those
+  columns nullable before upgrading to MediaWiki 1.31.
+  maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
