+# Changelog
+
+## 4.0.0
+
+- Improve performance by changing the method for detecting whether a DOM node is focusable or not. It's expected that this change will *not* affect results; but this is a major version bump as a warning for you to check your edge cases before upgrading.
+
+## 3.1.2
+
+- Fix reference to root element that caused errors within Shadow DOM.
+
+## 3.1.1
+
+- Allow module to be imported by non-browser JavaScript.
+
+## 3.1.0
+
+- Add `tabbable.isFocusable` and `tabbable.isTabbable` functions.
+
+## 3.0.0
+
+- Add `[contenteditable]` elements.
+
+## 2.0.0
+
+- Add `<audio>` and `<video>` elements with `controls` attributes.
+- Only consider radio buttons tabbable if they are the `checked` on in their group, or if none in their group are `checked`.
+
+## 1.1.3
+
+- Fix bug causing SVG elements to precede elements they should follow in the tab order in IE.
+
+## 1.1.2
+
+- Ensure `querySelectorAll` receives a string argument.
+
+## 1.1.1
+
+- Fix crash when you call `tabbable(document)` (passing the `document` element).
+
+## 1.1.0
+
+- Add `includeContainer` option.
+
+## 1.0.8
+
+- Allows operation against elements that reside within iframes, by inspecting the element to determine its correct parent `document` (rather than relying on the global `document` object).
+
+## 1.0.7
+
+- Ensure stable sort of `tabindex`ed elements even in browsers that have an unstable `Array.prototype.sort`.
+
+## 1.0.6
+
+- Check `tabindex` attribute (via `getAttribute`), in addition to `node.tabIndex`, to fix handling of SVGs with `tabindex="-1"` in IE.
+
+## 1.0.5
+
+- Children of `visibility: hidden` elements that themselves have `visibility: visible` are considered tabbable.
+
+## 1.0.4
+
+- Fix IE9 compatibility.
+
+## 1.0.3
+
+- Further improvements to caching.
+
+## 1.0.2
+
+- Fix overaggressive caching that would prevent `tabbable` from knowing an element's children had changed.
+
+## 1.0.1
+
+- Fix handling of `<a>` elements with `tabindex="0"`.
+
+## 1.0.0
+
+- Initial release.
