- No domain predicates needed in (stratified) aggregates
- Arbitrary literals in aggregates
- Lua scripting language to write custom functions
- #include directives
- #minimize statements with priorities
- #domain statements
- #show/#hide statements with extended functionality
- #external statements (extends lparse counterpart)
