0.12.3

• Add Value::car and Value::cdr.

0.12.2

• Added Env::cons.

0.12.1

• Added Env::make_user_ptr, Value::get_user_ptr, Value::get_user_finalizer.

0.12.0

• Added Env::make_vector and Env::vector functions.
• Added a default implementation for Transfer::type_name. This raised the minimum supported Rust version to 1.38 (for std::any::type_name()).
• Added function to copy a Lisp string's content to a buffer Value::copy_string_contents.
• Deprecated unwrap_or_propagate, and marked it as unsafe.

0.11.0

• Made env.call a lot more flexible. Also added value.call.
• Added rust-wrong-type-user-ptr to wrong-type-argument classification.
• Deprecated emacs::module_init! and emacs::export_functions!.
• ReplacedIntoLisp implementation for AsRef<str> with separate implementations for &str and &String.

0.10.3

• Made #[defun] function signatures display correctly in help-mode and helpful-mode.

0.10.2

• Added defun_prefix option to #[module].
• Fixed #[defun] not handling raw identifiers correctly.

0.10.1

• Made Vector::get generic by return type.
• Added FromLisp and IntoLisp implementations for most integer types, and an optional feature lossy-integer-conversion to control their behavior. This allows them to be used in #[defun] signatures.
• Made Env::message take AsRef<str>, not just a &str.

0.10.0

Various ergonomics improvements

• Added Vector type to represent Lisp's vectors.
• Allowed Rc and Arc to be embedded in user-ptr by marking them as Transfer.
• Removed libc dependency.
• Removed Transfer::finalizer.
• Deprecated env.is_not_nil(value) in favor of value.is_not_nil().
• Deprecated env.eq(value1, value2) in favor of value1.eq(value2).
• Improved Lisp-to-Rust string conversion's performance by making utf-8 validation optional, behind a feature, utf-8-validation.
• Improved Rust-to-Lisp string conversion's performance by not creating a temporary CString.
• Fixed a safety bug in which short-lived references were allowed to be embedded in user-ptr.
