To help global users use Salesforce in their language, German (Liechtenstein), Spanish (Andorra), Svenska (Finland), and the 30 new English language variations can be used to localize apps, custom labels, custom objects, and field names. These platform-only languages are available everywhere in the application that a language can be selected. However, all standard Salesforce labels default to English. Use Translation Workbench to customize the translations for these languages.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the mobile app in all editions, except Database.com
