doc/vimwiki.txt

@@ -3024,7 +3024,6 @@ Limitations:
   - Opening very large files may be slow when folding is enabled.
   - 'list' folding is particularly slow with larger files.
   - 'list' is intended to work with lists nicely indented with 'shiftwidth'.
-  - 'syntax' is only available for the default syntax so far.
 
 The options above can be suffixed with ':quick' (e.g.: 'expr:quick') in order
 to use some workarounds to make folds work faster.
