**Full Changelog**: https://github.com/furbrain/CircuitPython_async_button/compare/1.2.1...1.2.2

This release includes the MultiButton, which allows waiting on clicks from multiple buttons simultaneously

This release introduces the `interval` parameter for `SimpleButton` and `Button` - this lets you set the underlying polling rate both for the keys object and the background task. This improves performance by reducing unnecessary polling.

The `Button` task now pays attention to the timestamp on `keypad.Event` so clicks received during a long running task are processed appropriately even if the background task did not run at the correct time. This does not apply to Blinka based systems.
