+=== Important pre-upgrade notes for 1.31 ===
+* If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
+ schema changes, and cannot have downtime to run migrateArchiveText.php and
+ apply patch-drop-ar_text.sql manually, you'll have to apply a default value
+ 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.
+* The CologneBlue and Modern skins are no longer bundled with the tarball. You
+ will need to remove the wfLoadSkin() calls from your LocalSettings.php or
+ download them separately
+ (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).
