# Changelog
## `v0.12.0`
* Introduced `Language::static_text` to optimize tokens that always appear with the same text (estimated 10-15% faster tree building when used, depending on the ratio of static to dynamic tokens).
* Since `cstree`s are lossless, `GreenNodeBuilder::token` must still be passed the source text even for static tokens.
* Internal performance improvements for up to 10% faster tree building by avoiding unnecessary duplication of elements.
* Use `NonNull` for the internal representation of `SyntaxNode`, meaning it now benefits from niche optimizations (`Option<SyntaxNode>` is now the same size as `SyntaxNode` itself: the size of a pointer).
