+- [#169](https://github.com/ruby-syntax-tree/syntax_tree/pull/169) - You can now pass `--ignore-files` multiple times.
+- [#157](https://github.com/ruby-syntax-tree/syntax_tree/pull/157) - We now support tracking local variable definitions throughout the visitor. This allows you to access scope information while visiting the tree.
+- [#170](https://github.com/ruby-syntax-tree/syntax_tree/pull/170) - There is now an undocumented `STREE_FAST_FORMAT` environment variable checked when formatting. It has the effect of turning _off_ formatting call chains and ternaries in special ways. This improves performance quite a bit. I'm leaving it undocumented because ideally we just improve the performance as a whole. This is meant as a stopgap until we get there.

+### Changed
+
+- [#170](https://github.com/ruby-syntax-tree/syntax_tree/pull/170) - We now require at least version `1.0.0` of `prettier_print`. This is to take advantage of the first-class string support in the doc tree.
