[0.5.0] - 2025-07-25

Note: this is supposed to be essentially a 1.0 release candidate. If there are no problems with this release, it will be released as 1.0 after some time.

• Breaking Bump MSRC from 1.54 to 1.56
• Breaking: Remove proc-macro2 from default features
• Breaking: Make StringLit<String>::into_value return String instead of Cow<'static, str>. Make ByteStringLit<String>::into_value return Vec<u8> instead of Cow<'static, [u8]>.
• Add support for C string literals
• Limit number of # as delimiter of raw string literals to 256 (to align with spec)
• Fix license in Cargo.toml to use proper SPDX format (in #19, thanks @​atouchet)
• Fix error span for InvalidStartOfUnicodeEscape errors

[0.4.2] - 2025-07-25

• Fix incorrect byte string value with non-ASCII \xHH byte string escapes
  • ByteStringLit::parse(r#"b"\xff""#).unwrap().value() would return [0xc3, 0xbf] instead of [0xff].
• Remove CR LF normalization to align with spec
  • This is technically a breaking change, but released with a minor version bump as it just aligns with the specification. It is extremely unlikely to affect any real world use case.
• Fix incorrect error span for out-of-range Unicode escapes

[0.4.1] - 2023-10-18

• Fixed incorrectly labeling 27f32 a float literals in docs.
• Added hint to integer literal docs about parsing as u128.

[0.4.0] - 2023-03-05

Added

• Add ability to parse literals with arbitrary suffixes (e.g. "foo"bla or 23px)
• Add suffix() method to all literal types except BoolLit
• Add IntegerBase::value
• Add from_suffix and suffix methods to FloatType and IntegerType
• Add FromStr and Display impls to FloatType and IntegerType

Changed

• Breaking: Mark FloatType and IntegerType as #[non_exhaustive]
• Breaking: Fix integer parsing for cases like 27f32. Literal::parse and IntegerLit::parse will both identify this as an integer literal.
• Breaking: Fix float parsing by correctly rejecting inputs like 27f32. A float literal must have a period OR an exponent part, according to the spec. Previously decimal integers were accepted in FloatLit::parse.
• Improved some parts of the docs

Removed

• Breaking: Remove OwnedLiteral and SharedLiteral

[0.3.0] - 2022-12-19

Breaking

• Bump MSRV (minimal supported Rust version) to 1.54

Added
