+## New line breaking mode
+
+So far, `babel/lua` provided three linebreaking modes in the `ini`
+settings, for ‘hyphenated’ (the default), ‘CJK’ and ‘Southeast Asian’. A
+new mode has been added for ‘unhyphenated’ languages, like Arabic or
+Malayalam. It adjusts the paragraphs parameters to allow large spaces
+between words. Although for European standards the result may look odd,
+in some scripts this has been the customary practice. It works with
+`xetex`, too.
+
+So, currently there are two modes for scripts that separate words with
+spaces, and two modes for scripts with no word separator.
+
 ## Transforms added to `ini` files
 
 **Czech, Polish, Portuguese, Slovak, Spanish** `hyphen.repeat` Explicit hyphens behave like `\babelhyphen{repeat}`.
