By default Multi Language support should be included - Customers would like Multi Language support by default for the K2 Product, specifically K2 Five (and K2 Cloud).
In the past, customers could download and use the Multi-language control from the Community site, which is no longer available.
This is now available with the 5.8 release, with German, French, Spanish and Arabic available for all system or designer UIs, and capabilities to have a single SmartForm in multiple languages OOB.
This applies for K2 designer/K2 package and deployment tool/K2 websites having them available in multiple languages (French being the one we need for our customers) but also in Business User Interfaces like K2 Smartforms/K2 workspace to have it available in different languages and being able to save as a user his favorite language.
