 ### Changed
 
 - [#45](https://github.com/ruby-syntax-tree/syntax_tree/issues/45) - Fix parsing expressions like `foo.instance_exec(&T.must(block))`, where there are two `args_add_block` calls with a single `&`. Previously it was associating the `&` with the wrong block.
+- [#47](https://github.com/ruby-syntax-tree/syntax_tree/pull/47) - Handle expressions like `not()`.
+- [#48](https://github.com/ruby-syntax-tree/syntax_tree/pull/48) - Handle special call syntax with `::` operator.
+- [#49](https://github.com/ruby-syntax-tree/syntax_tree/pull/49) - Handle expressions like `case foo; in {}; end`.
+- [#50](https://github.com/ruby-syntax-tree/syntax_tree/pull/50) - Parsing expressions like `case foo; in **nil; end`.
