WordPress 5 Database Changes?

I know the version number of the database changed with the 5 release from 38590 to 43764 (https://codex.wordpress.org/Current_events), but did the schema change at all? Were there any changes to the v5 database as compared to v4.9.8?

As far as I can see from https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/upgrade.php, the updater only looks for databases less than 37965 (if ( $wp_current_db_version < 37965 )), which indicates to me that nothing has changed between 4.9.8’s database and 5.0. Is this accurate?
