Sourced from chumsky's changelog.

[0.11.2] - 2025-11-05

Added

• Implement Default, PartialOrd, and Ord for SimpleSpan
• Implement PartialOrd and Ord for Rich

[0.11.1] - 2025-09-12

Fixed

• Patched compilation error that only appeared in release builds

[0.11.0] - 2025-09-11

Added

• The set(...) combinator, which may be used to conveniently parse a set of patterns, in any order
• Support for non-associative infix operators are now supported by the .pratt(...) combinator
• Parser::try_foldl, allowing folding operations to short-circuit in a manner similar to Parser::try_map
• Parser::contextual, which allows a parser to be disabled or enabled in a context-sensitive manner
• Implemented ValueInput for IterInput, which was previously missing
• More types that implement the State trait:
  • RollbackState, which reverts parser state when a parser rewinds and may be used to, for example, count the number of times a pattern appears in the input
  • TruncateState, which truncates a vector when a parser rewinds, and may be used to implement an arena allocator for AST nodes
• Implemented IterParser for a.then(b) when both a and b are both IterParsers that produce the same output type

Changed

• Made lifetime bounds on recursive and ParserExtra more permissive
• Improved support for grapheme parsing
• Text parsers now report labels
• Parser::filter now generates a DefaultExpected::SomethingElse label instead of nothing (this can be overridden with the .labelled(...) function)
• Improved areas of documentation
• Make whitespace parsers reject codepoints that are vulnerable to CVE-2021-42574
• Maybe the select! parser more permissive, accepting any implementor of Input instead of requiring ValueInput too

Fixed

• Many minor incorrect debug-only sanity checks have been fixed
• Many minor span and error prioritisation behavioural problems have been fixed (most notably, Parser::try_map)
• The .rewind() parser no longer rewinds any secondary error that were encountered
• Accidental text::ascii::keyword lifetime regression

[0.10.1] - 2025-04-13

Added

• Implemented Container for VecDeque
• New section covering recursion in the guide
