0.9.2

• Add syn::parse_token_trees to parse tokens from a string. Token trees are much simpler than an AST. This makes them easier to work with when they are sufficient for the task at hand, such as for example expanding a function-like macro. (#52, thanks @SimonSapin)

0.9.1

• Make the fields of syn::Crate public (1271b29)
• Fixes to parsing of tokens within a macro invocation (f7922e3 and e6042a6)
• Parsing of byte and char literals (615cf6a)

0.9.0

• Enum discriminant values and array lengths now support expressions instead of just usize literals (#31).
• Update quote dependency to 0.3. Make sure to check those release notes for an important update affecting repetitions.
• Lots of progress on parsing Rust syntax beyond structs and enums (#4).

0.8.7

• Add Generics::split_for_impl which simplifies the handling of complex generic type signatures in a trait impl.

let (impl_generics, ty_generics, where_clause) = generics.split_for_impl();

quote! {
    impl #impl_generics MyTrait for #name #ty_generics #where_clause {
        // ...
    }
}

0.8.6

• Add VariantData::fields_mut to view the fields of a struct or tuple variant as a mutable slice (#26)

0.8.5

Some helper functions to simplify working with lifetimes and attributes:

• Lifetime::new("'a") -> Lifetime
• LifetimeDef::new("'a") -> LifetimeDef
• attribute.name() -> &str (equivalent to the previously existing attribute.value.name())

0.8.4

• Parsing for raw string literals like r"..." and r##"..."##.

0.8.3

(yanked)

0.8.2

• Fix a literal "///" appearing at the beginning of generated docstrings: rust-lang/rust#35900 (comment).

0.8.1

• Workaround for a compiler bug when building in release mode with rustc 1.12.0. Versions before and after 1.12.0 were not affected. rust-lang/rust#36875
