A language pack is not a release for its own and has to be installed over a stable release with the same version number and platform. It contains resource files for a specific language and platform to show, e.g., menus, dialogs, error messages in your language. It may contain translated Help content. Language packs are created if at least 80% of the user interface (UI) is translated. In case it is not fully localized, some elements of the UI or help topics will display in English as default language.
