# Changelog

## [1.3.0] - 2026-03-16

### Changed

- Migrate parser from `lib-ruby-parser` (Ruby 3.1.2) to `ruby-prism` (Ruby 3.3+)
- Support Ruby 3.2, 3.3, 3.4+ syntax
- Native handling of all encodings (ASCII, US-ASCII, etc.) — no custom decoder needed
- Error-tolerant parsing: always produces an AST, even with syntax errors
- Prism is Ruby's official default parser since 3.3

### Removed

- `lib-ruby-parser` dependency replaced by `ruby-prism`

## [1.2.5] - 2026-03-16
