• Fixed Click 8.3 compatibility with rendering defaults in help text.

Version 1.9.0 (2025-09-16)

[!WARNING] Version 1.9.0 deprecates support for a lot of old versions of things:

• Python 3.7 support is removed. The minimum supported Python version is 3.8.
• Click 7 support is removed. The minimum supported Click version is 8.0.
• Rich 10 and 11 support is removed. The minimum supported Rich version is 12.

[!WARNING] Version 1.9.0 introduces a minor breaking change: The DEFAULT_STRING, ENVVAR_STRING, REQUIRED_STRING, and DEPRECATED_STRING config options are now rendered with Text.from_markup. So for example, REQUIRED_STRING = "[required]" would be rendered as Rich markup. You must now escape the rich markup: REQUIRED_STRING = "\\[required]"
