+✨ Added `<pf-v6-helper-text>` replacing `<pf-v5-helper-text>`. Helper text now follows
+PatternFly v6 design specs.
+
+```html
+<pf-v6-helper-text variant="error" has-icon>Password is too short</pf-v6-helper-text>
+```
+
+**Breaking Changes from v5**
+
+- Renamed tag from `<pf-v5-helper-text>` to `<pf-v6-helper-text>`
+- Update bare module import to point to v6: `import '@patternfly/elements/pf-v6-helper-text/pf-v6-helper-text.js'`
+- ✨ Added `has-icon` boolean attribute for opt-in default variant icons
+- ✨ Added `dynamic` boolean attribute for dynamic validation contexts
+- ✨ Added `screen-reader-text` attribute for custom assistive announcements
+- ✨ Added `icon` slot for custom icon markup (replaces `icon` and `icon-set` attributes)
+- ✨ Added `icon` and `text` CSS parts
+- ✨ Added `color-scheme` support via `light-dark()`
+- ✨ Added v6 design tokens
+- CSS custom properties renamed from `--pf-v5-c-helper-text--*` to `--pf-v6-c-helper-text--*`
+- Removed `icon` attribute (use `has-icon` for default icons or `icon` slot for custom)
+- Removed `icon-set` attribute
+- Removed dependency on `<pf-v5-icon>` (uses inline SVG icons)
