2.0.0

This release contains a batch of syntax tree improvements to incorporate ongoing Rust language development from the past 3.5 years since syn 1.

It never seems like an ideal time to finalize a syntax tree design, considering the frankly alarming number of syntax-disrupting language features currently in flight: keyword generics, restrictions, capabilities and contexts, conditional constness, new varieties of literals, dyn revamp such as explicitly dyn-safe traits and dyn-star, expression syntax in various phases of being added or being torn out (const blocks, try blocks, raw references), auto traits and negative impls, generalizations to higher rank trait bounds, async closures and static async trait methods, postfix keywords, pattern types, return type notation, unsafe attributes, …

The plan continues to be the same as laid out originally in the 1.0.0 release announcement:
