📋 更新摘要

4 outdated dependencies identified. decorator/pyte have hard caps in setup.py; mock is deprecated (absorbed into stdlib); setuptools minimum is 10+ years old. The project's Python 2.7/3.x compatibility shims (pathlib2, backports.shutil_get_terminal_size) suggest deep abandonment. Unpinned deps in requirements.txt (flake8, pytest, pexpect, pypandoc, twine, etc.) — their actual installed versions are unknown; they should be audited against current major releases if the project is revived.

📦 变更清单

🔴 decorator: <5 → >=5.0,<6
decorator<5 excludes modern 5.x versions; current is 5.2.x with Python 3.8+ support

🔴 pyte: <0.8.1 → <0.9.0
pyte<0.8.1 is a hard cap from ~2017; pyte 0.9.0+ is stable and compatible

🟡 mock: latest available (unpinned) → remove dependency (use unittest.mock)
mock package is deprecated; builtin unittest.mock has been standard since Python 3.3

🔴 setuptools: >=17.1 → >=70.0
setuptools>=17.1 from ~2014 is severely outdated; current is 70.x with important security/feature updates
