 ### Known issues
-- stepping in imported inline functions does not work
+- performance of Python bindings.
-- single stepping sometimes works incorrectly in some other scenarios
-- variable inspections may not work properly
 
 _Note:_ Supporting the DWARF 2 specification means that the debugger tool recognizes Kotlin as C89, because before the DWARF 5 specification, there is no identifier for the Kotlin language type in specification.
