v0.14.3

• Re-export syn from darling to avoid requiring that consuming crates have a syn dependency.
• Change <SpannedValue<T> as FromMeta> impl to more precisely capture the value span, as opposed to the span of the entire item.
• Add darling::util::{AsShape, Shape, ShapeSet} to improve "shape" validation for structs and variants. #222

v0.14.2

• Derived impls of FromMeta will now error on literals, rather than silently ignoring them. #193
• Don't include property paths in compile errors when spans are available. #203

v0.14.1

• Fix a bug where using a trait that accepts #[darling(attributes(...))] without specifying any attributes would emit code that did not compile. #183
• Impl Clone for darling::Error #184
• Impl Fromdarling::Error for syn::Error #184
• Add Error::span and Error::explicit_span methods #184

v0.14.0

• BREAKING CHANGE: Remove many trait impls from util::Flag.
  This type had a number of deref and operator impls that made it usable as sort-of-a-boolean.
  Real-world usage showed this type is more useful if it's able to carry a span for good errors,
  and that most of those impls were unnecessary. #179
• Remove need for #[darling(default)] on Option<T> and Flag fields #161
• Improve validation of enum shapes #178
• Bump proc-macro2 dependency to 1.0.37 #180
• Bump quote dependency to 1.0.18 #180
• Bump syn dependency to 1.0.91 #180

v0.13.4

• Impl FromMeta for syn::Visibility #173

v0.13.3

• Add error::Accumulator #164
• Impl FromMeta for syn::Type and its newtype variants #172

v0.13.2

• Impl FromMeta for syn::ExprPath #170

v0.13.1

• Add FromAttributes trait and macro #151

New Contributors
