[`v2.7.2`](https://redirect.github.com/ether/etherpad/blob/HEAD/CHANGELOG.md#272)

[Compare
Source](https://redirect.github.com/ether/etherpad/compare/2.7.1...2.7.2)

##### Notable enhancements and fixes

- Accessibility pass: corrected dialog semantics, improved focus
management, added missing icon labels, and set the `html lang` attribute
correctly.
- Chat: clicking the chat icon works again, disabled toggles render
properly, and the username layout no longer overflows.
- `/export/etherpad` now honors the `:rev` URL segment, so
revision-specific exports return the requested revision instead of the
latest.
- Undo / redo now scrolls the viewport to follow the caret, so reverted
edits stay in view.
- Page Down / Page Up now scrolls by viewport height instead of a fixed
line count, matching standard editor behavior on tall and short windows
alike.
- Editbar: caret is restored to the pad after changing a toolbar select,
so typing continues in the document instead of falling through to the
toolbar.
- Admin: i18n is restored on `/admin` so the admin UI is translated
again.
