v2.0.0

What's New

Instant Visual Feedback

• Active tab class (is-active) is now applied immediately on click — no more waiting for content to finish transitioning.

Full WAI-ARIA Tabs Pattern

• Arrow key navigation: Left/Right/Up/Down to move between tabs, Home/End to jump to first/last.
• Roving tabindex: only the active tab is focusable via Tab key.
• Removed aria-expanded from tabs mode (only used in accordion mode now).
• Focusable panels: tab panels have tabindex="-1" so keyboard users can Tab into content.
• data-tab-list attribute: optional wrapper for correct role="tablist" placement.

Smart Autoplay

• Pauses on hover over the tab container.
• Pauses on keyboard focus within the container.
• Resets timer when user manually switches tabs.
• Pauses when the browser tab is hidden (via visibilitychange).

Deep Linking

• URL hash support (e.g. #tab-2) activates the matching tab on page load.
• Listens for hashchange events for dynamic navigation.

Custom Events

• tabs:change event emitted on the container with { tabId, link, content, instance } detail.

Bug Fixes

• All <video> elements in a panel now play/pause (previously only the first).
• Added missing showAllPanelsPlain() function that caused a ReferenceError when calling disable().
