Sourced from darling's changelog.

v0.24.0 (July 30, 2026)

• Update syn to v3 #431
• Add impl ToTokens for SpannedValue #423
• Allow data magic field for FromDeriveInput to be any type that implements TryFrom<&syn::Data, Error = darling::Error> without needing to use #[darling(with = ...)] syntax #391

v0.23.0 (December 3, 2025)

• Bump MSRV to 1.88.0; there have been no code changes that caused this, but due to dependency issues CI no longer works on 1.56.0 #357

v0.22.0 (December 2, 2025)

• BREAKING: Remove fnv dependency, as runtime performance gain does not justify additional dependency. This was exposed to users of darling::usage, so it may be breaking for them #373
• Add #[darling(default = || expr(val))] support, allowing a closure where a path was previously required #380
• Preserve span information for paths given to darling::util::Callable as literal strings
• Fix some documentation typos

v0.21.3 (August 22, 2025)

• Fix: Forward Override::<T>::from_expr to T::from_expr #371

v0.21.2 (August 14, 2025)

• Add #[darling(from_expr = ...)] when deriving FromMeta to support overriding the key-value form #369
• Keep parsing the body and type params even if there are errors from parsing attributes. #7
• Support #[darling(with = ...)] on the generics field when deriving FromDeriveInput.
• Return an error, rather than panicking, when doing shape validation on a union. #365

v0.21.1 (August 4, 2025)

• Track all alternate field names, and show them in error message if there aren't too many. #325
• Track all alternate values for enum variants, and show them in error messages if there aren't too many. #362

v0.21.0 (July 10, 2025)

• Potentially breaking: Emit error when an attribute path is present in both attributes and forward_attrs. #336
• Support parsing attributes which contain keywords #238
• Add SpannedValue::into_inner #342
• Add #[darling(derive_syn_parse)] to also impl syn::parse::Parse when deriving FromMeta #285
• Make impl FromMeta for syn::TypePath support both quote-wrapped and bare values #351
• Add util::PreservedStrExpr #346
• Impl UsesTypeParams and UsesLifetimes for WithOriginal #215
• Update error message emitted by <() as FromMeta>::from_list to allow use of () as a #[darling(flatten)] target #353

v0.20.11 (March 28, 2025)

• Support #[darling(with = ...)] on the data field when deriving FromDeriveInput. This allows the use of simpler receiver types, such as a Vec of enum variants.
