0.11.5

• Implement an AST folder, syn::fold::Folder (#85, thanks @gnzlbg)

• Expose parsers and parser combinators for parsing custom function-like macro input

  extern crate syn;
  #[macro_use] extern crate synom;
  
  use syn::Expr;
  use syn::parse::expr;
  
  // An expression surrounded by [[ ... ]].
  named!(double_bracket_expr -> Expr,
      delimited!(punct!("[["), expr, punct!("]]"))
  );
  
  fn main() {
      let input = "[[ 1 + 1 ]]";
  
      let parsed = double_bracket_expr(input).expect("double bracket expr");
  
      println!("{:?}", parsed);
  }

0.11.4

AST changes to reflect changes in rustc

• Rename ExprKind::Vec to ExprKind::Array
• Change the content of ExprKind::Closure from a Block to Expr
• Support expression values for break statements
• Support attributes on fields in a struct literal expression (FieldValue) and pattern (FieldPat)
• Add a new type of where predicate - EqPredicate
• Combine Ty::ObjectSum and Ty::PolyTraitRef into Ty::TraitObject
• Add Ty::Mac to support macros in type position

Other breaking changes

• Remove the custom-derive registry that was used for expanding derives on stable rust; real custom derives will be stable very soon
• Unify BlockCheckMode and Unsafety (#66, thanks @shepmaster)

Non-breaking changes

• Rename parse_macro_input to parse_derive_input and MacroInput to DeriveInput now that there are other types of procedural macros that are not derives; the old names will continue to work because they have appeared in so many Macros 1.1 guides (#63, thanks @SimonSapin)
• Support parsing macro invocations that use namespaced paths like a::b!(...)
• The AST walker syn::visit::Visitor now supports all AST types (#79, thanks @mystor)

0.10.6

• #[derive(Hash)] for all the syntax tree types (#73)

0.10.5

• Add syn::parse_ident (#71)
