It solves the problem of manually tracking which package versions work with which Python versions by providing tools to check package availability, discover compatible versions from PyPI, and validate versions before installation. The core functionality depends only on packaging, with optional dependencies for CLI tools and GitHub integration.\n\nTypically used when you need to support multiple Python versions in a project or when deploying code to environments with different Python versions and package availability. It includes a built-in registry of compatibility information for popular packages like numpy, pandas, and torch, and falls back to PyPI discovery for packages not in the registry.","worth_installing":"Yes, if you need to manage package versions across multiple Python environments or automate version compatibility checks. The low install friction, active maintenance, permissive license, and zero known vulnerabilities make it a safe choice. Start with the basic import/version-check functions; the CLI and GitHub utilities are optional. Not necessary if you only target a single Python version or manually manage dependencies."},"id":"feu","links":{"html":"https://skillfed.io/packages/feu","md":"https://skillfed.io/packages/feu.md","pypi":"https://pypi.org/project/feu/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-10","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"feu","python_support":"supports_current","summary":"A lightweight Python library for managing packages and versions across different Python environments"},"popularity":{"monthly_downloads":938001,"position":4688,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.8.1"}
