• animationDuration config to control how long the highlight transition takes. (#104)
• allowScroll config to lock body scroll while a tour is active.
• onDoneClick hook, fired when the done button on the final step is clicked. (#500)
• data property on a step for passing arbitrary data, accessible from hooks for custom per-step logic. (#539)

• Breaking - Custom popover footer buttons no longer get auto styled, style them using .driver-popover-footer button selector (#555)
• The popover exposes driver-popover-side-* and driver-popover-align-* classes as per the rendered side and alignment https://github.com/nilbuild/driver.js/issues/608
• Arrow positioning has been fixed https://github.com/nilbuild/driver.js/issues/558 https://github.com/nilbuild/driver.js/issues/429 https://github.com/nilbuild/driver.js/issues/406

• Document event listener leak in onDriverClick that left handlers attached after the tour was destroyed. (#452)
• Dropped the CSS :has() selector for broader browser compatibility. (#586)
• Positioned highlighted elements and their children (e.g. dropdown menus) no longer get clipped. (#454, #563)
• removeChild DOMException when re-rendering a popover whose wrapper was already detached from the DOM. (#572)
• Close button on a single-element highlight() popover did nothing when clicked. It now closes the popover by default, respecting allowClose and any custom onCloseClick. (#444)
