0.11.1

• Update unicode-xid dependency to 0.0.4 (#83, thanks @SimonSapin)

0.10.7

• Update unicode-xid dependency to 0.0.4 (backport #83, thanks @SimonSapin)

0.11.0

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)

0.10.4

(yanked)

0.10.3

0.10.2

• Make the fields of Expr public (#65, thanks @shepmaster)

0.10.1

• Export ExprKind which was mistakenly not public (#64, thanks @KodrAus)
