## [0.3.0] - 2026-09-16

### Fixed
- Scanning is linear in the length of the document instead of quadratic. The scanner
addresses text by character offset, and resolving one against a UTF-8 string means
walking it from the start, so calling `mb_substr()` once per character made the cost
grow with the square of the length. The document is now split into characters once
and indexed. Measured over a 183 KB document, a parse/modify/serialize round trip
drops from 21.4s to 128ms.

### Added
- Scanner complexity tests, asserting a ratio between two input sizes rather than a
wall-clock budget so they mean the same thing on any machine.
- Scanner multibyte tests covering offsets, token values, lengths, line and column
numbers and the token stream across 2-, 3- and 4-byte characters, Greek, Thai,
Cyrillic, CJK and emoji. Output is unchanged by this release: all 31 storefront
locale files of a production Shopify theme round-trip byte-identically.

## [0.2.0] - 2026-01-26

### Fixed
- Edits landing at the wrong position when a multibyte character preceded the target.
`Editor` and `Formatter` measured in bytes while the parser reported character
offsets; both now agree on characters.
