Summary

AI summary

New --check-update and --update flags add version selection with release notes, plus macOS SSL certificate fix.

Full changelog

--check-update — Show available updates with categorized release notes (security fixes, bug fixes, new features, performance, improvements) color-coded by category before deciding to update
--update [VERSION] — Optionally specify a target version to update to instead of always installing the latest (e.g. --update v2.4.1). Lists all available versions when multiple updates are pending
Release notes in --update — The update flow now displays categorized release notes for all versions between current and target before downloading

macOS SSL certificate fix — Fixed CERTIFICATE_VERIFY_FAILED error when running --update or --check-update on macOS PyInstaller-bundled binaries. The bundled OpenSSL now explicitly loads system certificates from /etc/ssl/cert.pem and other common paths
--help completeness — --version, --check-update, --update, --log-file, --overwrite, and --exclude now all appear in --help output
