Release Notes for Harmony 20.0.0, build 15996 (2020-06-11):

Important enhancements have been done to the Harmony Server database. As such, in order for Harmony 20 clients to function properly, the database server must be updated to Harmony 20.

Furthermore, the dictionary files (.dict) in the database must be updated with the ones included in the Harmony 20 packaging. To do this, copy the files from the following location:

• Windows: C:\Program Files (x86)\Toon Boom Animation\Toon Boom Harmony 20 Premium\etc\USADB_templates\dicts
• macOS: /Applications/Toon Boom Harmony 20 Premium/Harmony Premium.app/Contents/tba/etc/USADB_templates/dicts
• GNU/Linux: /usr/local/ToonBoomAnimation/harmonyPremium_20/etc/USADB_templates/dicts

And paste them in the following location in your database, replacing the existing files:

/USA_DB/dicts

Note that a database server running Harmony 20 is backward compatible with clients running older versions of Harmony.
