## [2.4.1] - 2026-10-28
### Changed
- 100% test coverage

## [2.4.0] - 2026-10-28
### Changed
- Parser regular expressions run in linear time (ReDoS safe)
- **Breaking:** `NaN` and `Infinity` are rejected: the builder throws, parsing and stringifying fail
### Removed
- **Breaking:** deprecated `useSelfAsValueConverter()` and the boolean `combineExpression` overload; use `CombineExpressionFlags`
- **Breaking:** conversion type `'finiteNumber'`; `'number'` is finite only

## [2.3.0] - 2026-10-23
### Added
- `equals`, `notEquals` and the comparisons accept a `number` or `Date` on the left (`lessThan(0, 0)`); an empty string or `0` on the left is no longer rejected
### Changed
- **Breaking:** `ConstructorClass` is `new () => IExpressionParser` instead of `Function`
- **Breaking:** `ExpressionType` and `CombineExpressionFlags` members are PascalCase (`ExpressionType.Equals`, `CombineExpressionFlags.SkipOverwrite`); their values are unchanged
### Removed
- **Breaking:** deprecated `OrderByDirection` and the builder overloads using it; use `CollectionOrderDirection` (`'asc'` / `'desc'`)
