 ## Unreleased
+### Added
+* New language available: Arabic (MSA) (`'ar'`). Add language code constants and tests.
+
+  Note: older library versions also support the new language, this update only
+  adds new code constants.
 ### Fixed
 * Change document upload to use the path `/v2/document` instead of `/v2/document/` (no trailing `/`).
   Both paths will continue to work in the v2 version of the API, but `/v2/document` is the intended one.
