CHANGELOG.md

Changelog

0.9.3 (2026-02-18)

• Lower requires-python to >=3.8; add typing_extensions runtime dependency
• Add from __future__ import annotations to io.py, helpers.py, and entry.py

0.9.2 (2026-02-18)

• Fix off-by-one in Entry.seek() at exact sector boundaries (< → <=)

0.9.1 (2026-02-18)
