Refer to the project's GitHub releases for specific changes.","message":"The library is currently in 'Beta' development status (Development Status :: 4 - Beta). This implies that APIs and core behaviors might still evolve and change in future versions without strict adherence to semantic versioning until a stable 1.0 release.","severity":"gotcha","affected_versions":"All 0.x.x versions"},{"fix":"Wrap `download()` calls in `try...except` blocks to handle potential exceptions such as `requests.exceptions.RequestException`, `IOError`, or other custom exceptions the library might raise.","message":"While designed for robustness, the basic `download` function, as shown in minimal usage examples, does not explicitly include `try-except` blocks for error handling. For production-ready applications, it is essential to implement comprehensive exception handling for network issues, file system errors, or unexpected server responses.","severity":"gotcha","affected_versions":"All versions"},{"fix":"Pass the `sha256` argument to the `download` function, e.g., `download(url, filename='my_file.zip', sha256='expected_sha256_hash')`.","message":"Version 0.0.2 introduced an optional SHA256 integrity check. If downloading critical files where data integrity is paramount, it is highly recommended to provide the expected SHA256 hash to the `download` function to verify the file's authenticity and ensure it hasn't been corrupted during transfer. This check is not enabled by default.","severity":"gotcha","affected_versions":"0.0.2 and later"},{"fix":"Review the project's documentation and source code to confirm specific feature support if your use case requires complex download management scenarios.","message":"The library describes itself as a 'minimal' downloader. While it supports resumable downloads and retries, users accustomed to more feature-rich download managers (e.g., those offering multi-part downloads, advanced proxy configurations, or sophisticated handling of dynamic/expiring URLs) might find certain advanced capabilities or extensive customization options to be limited.","severity":"gotcha","affected_versions":"All versions"}],"env_vars":null,"last_verified":"2026-04-12T00:00:00.000Z","next_check":"2026-07-11T00:00:00.000Z"}
