+Added `<pf-v6-tooltip>` replacing `<pf-v5-tooltip>`. Tooltip now follows
+PatternFly v6 design specs.
+
+```html
+<pf-v6-tooltip content="Copy to clipboard">
+  <button>Copy</button>
+</pf-v6-tooltip>
+```
+
+**Breaking changes from v5:**
+
+- Tag name changed from `pf-v5-tooltip` to `pf-v6-tooltip`
+- `visible` attribute replaces programmatic-only visibility
+- `entry-delay` and `exit-delay` attributes added (300ms default)
+- `alignment` attribute replaces `isContentLeftAligned` (accepts `start`/`end`)
+- `no-flip` inverted boolean replaces `enableFlip`
+- `content` slot added for rich HTML content
+- Cancelable `show`/`hide` events with `reason` property
+- `silent` attribute for suppressing screen reader announcements
+- CSS custom properties replace inline style props (`maxWidth`, etc.)
+
+Users who need the react component's `trigger` prop are advised to use `<pf-v6-popover>` instead, or to use the cancellable `show`/`hide` events to prevent default behaviour.

+### Use a static live-region announcer for tooltip/popover content
+Tooltip and popover content lives in shadow DOM, which prevents `aria-describedby` from working cross-root. Use a shared static `role="status"` announcer element (visually hidden, appended to `document.body`) to announce content to screen readers. Announce on show, clear on hide. Provide a `silent` boolean attribute to opt out when authors provide their own accessible label.
+
+> Pattern established in `rh-tooltip` (RHDS): static `initAnnouncer()` + `announce(text)` in `show()`, clear in `hide()`. Adopted in `pf-v6-tooltip` (PFE).

 ### Consider cross-root ARIA limitations
-When composing elements across shadow boundaries, cross-root ARIA references don't work declaratively yet. This may require duplicating internal elements as a workaround. Client-side, ARIA IDL DOM properties (baseline 2025) can resolve cross-root references imperatively via JavaScript. Upcoming APIs like Reference Target will provide declarative solutions.
+When composing elements across shadow boundaries, cross-root ARIA references don't work declaratively yet. `ariaDescribedByElements` and similar IDL properties silently fail for light-to-shadow references. The [WPT test](https://github.com/web-platform-tests/wpt/blob/master/custom-elements/element-internals-aria-element-reflection.html) explicitly asserts cross-root refs produce an empty computed label. See also [WICG/aom#192](https://github.com/WICG/aom/issues/192) and [whatwg/html#5401](https://github.com/whatwg/html/issues/5401). Upcoming APIs like Reference Target ([WICG/webcomponents#1086](https://github.com/WICG/webcomponents/issues/1086)) will provide solutions. Keep cross-root IDL assignments as progressive enhancement.
