Changelog

Sourced from extendr-api's changelog.

0.9.0 — 2026-04-16

Added

• Implements CanBeNa for u8 and Rcomplex [#1000](extendr/extendr#1000)
• References to R native types are strictly checked &/&mut T, where T is a R native data type namely i32, f64, Rint, Rfloat, Rcplx, Rbool, and u8. We cannot perform coercion on borrowed data only owned data. [#1000](extendr/extendr#1000)
• Support for tuple-structs in IntoList and TryFromList [#985](extendr/extendr#871)
• Strings, Doubles, Integers, Complexes, and Logicals structs now have associated method new_with_na() to construct empty vectors of NA values [#871](extendr/extendr#871)
• It is now possible to provide your own Error-type in custom TryFrom<Robj>/ TryFrom<&Robj> calls. [#977](extendr/extendr#977)
• Implements ToVectorValue for Rstr enabling the creating of character matrices
• Added #[extendr(invisible)] attribute to allow functions to return invisibly in R [#946](extendr/extendr#946)
• An ignore field attribute to the macro derive(IntoList) called #[into_list(ignore)] [#864](extendr/extendr#864)
• Added TryFrom<Robj> for Vec<bool>—an Error::MustNotBeNA is returned if an NA is present [#864](extendr/extendr#864)
• Added impl From<&Vec<Robj>> for Robj [#864](extendr/extendr#864)
• Struct-level docs are now carried into generated wrapper documentation [#913](extendr/extendr#913)
• Impl-level docs are now appended to the struct-level documentation block in generated wrapper docs [#913](extendr/extendr#913)
• fn-level docs in impl blocks are now emitted in generated R docs with roxygen-style sections [#913](extendr/extendr#913)

Changed

• Breaking: Removed is_unbound_value() and unbound_value() as R_UnboundValue has been removed from the R-API [#1067](extendr/extendr#1067)
• Breaking: Removed R_NamespaceRegistry binding from extendr [#1069](extendr/extendr#1069)
• Breaking: MSRV has been bumped to 1.71
• Breaking: extendr_api::error::Result<> has been removed from the prelude
• Deprecates List::from_hashmap() in favor of the idiomatic TryFrom trait. replace List::from_hashmap() with List::try_from() [#982](extendr/extendr#982)
• Deprecates List::into_hashmap() in favor of the idiomatic TryFrom trait. replace List::into_hashmap() with HashMap::<String, Robj>::try_from() [#982](extendr/extendr#982)
• Deprecates Scalar::new() in favor of the idiomatic From::from() and Into traits [#971](extendr/extendr#971)
• Deprecates #[default = "value"] and replaces it with #[extendr(default = "value)] [#952](extendr/extendr#952)
• Deprecates Rstr::from_string() and Rstr::as_str() in favor of the standard library's From and AsRef traits. Use .from() and .as_ref() instead [#972](extendr/extendr#972)
• Breaking renamed TryFromRobj and the associated derive-macro to TryFromList [#]
• Breaking extendr_engine::with_r() requires a closure that returns a result [#1005](extendr/extendr#1005)
• Breaking removes Scalar trait in favour of providing read-only access to the wrapped types. [#1020](extendr/extendr#1020)
• Breaking we no longer permit TryFrom<Robj> for &T/&mut T as this violates Rust's memory model. [#1000](extendr/extendr#1000)

Fixed

• Panics raised in #[extendr] functions are now rethrown without prepending the unwrap message [#1055](extendr/extendr#1055)

0.8.0

Added

• Added ndim() method for RArray to get the number of dimension [#898](extendr/extendr#898).
• Added get_dim() method for RArray to get the dimension vector [#898](extendr/extendr#898).
• Added implementations for Index<[usize; 3]> and IndexMut<[usize; 3]> traits in RMatrix3D [#897](extendr/extendr#897)
• Type aliases RMatrix4D and RMatrix5D have been added [#875](extendr/extendr#875)
• ExternalPtr<T> and &ExternalPtr<T> can now be used as function arguments with appropriate type checking [#853](extendr/extendr#853)
