+- [#141](https://github.com/ruby-syntax-tree/syntax_tree/pull/141) - Use `q.format` for `SyntaxTree.format` so that the main node gets pushed onto the stack for checking parent nodes.
+- [#147](https://github.com/ruby-syntax-tree/syntax_tree/pull/147) - Fix rightward assignment token management such that `in` and `=>` stay the same regardless of their context.
