The documentation at https://orientdb.com/docs/3.2.x/ contains many references to OrientDB enterprise edition. This seems strange given that as far as I know enterprise edition no longer exists as a separate product.
Some examples:
https://orientdb.com/docs/3.2.x/misc/Overview.html#enterprise
https://orientdb.com/docs/3.2.x/admin/Backup-and-Restore.html#backup--restore (also has broken links to enterprise edition related materials)
https://orientdb.com/docs/3.2.x/index.html?search=enterprise%20edition lists 15 pages with references to enteprise edition.
