The record

Purpose: Poetry is a tool for dependency management and packaging in Python.
Dependency management: It installs and updates declared project libraries and provides a lockfile for repeatable installs.
Builds: Poetry can build projects for distribution and supports source distributions and wheels.
Publishing: Poetry can publish projects to PyPI and private repositories.
Dependency sources: Poetry uses PyPI by default and supports private repositories for finding packages and publishing projects.
Environment isolation: Poetry manages project environments that are isolated from the global Python installation.
Extensibility: Poetry supports using and building plugins to extend its functionality.
Python requirement: Poetry requires Python 3.10 or later.
Supported operating systems: The documentation describes Poetry as multi-platform, with Linux, macOS, and Windows as its target platforms.
Installation methods: The documentation describes installation with pipx, the official installer, or manual installation.
Shell completion: Poetry supports generating completion scripts for Bash, Fish, and Zsh.
Credential storage: When a supported system keyring is available, Poetry stores and retrieves repository passwords through the keyring; otherwise it falls back to an auth.toml file.
Certificate support: Poetry supports custom certificate authorities and certificate-based client authentication for repositories.
Resolver limitation: Dependency resolution can take time when PyPI package metadata is not available through the PyPI JSON API.
