 - Session naming: `/name <name>` command sets a display name shown in the session selector instead of the first message. Useful for distinguishing forked sessions. Extensions can use `pi.setSessionName()` and `pi.getSessionName()`. ([#650](https://github.com/badlogic/pi-mono/pull/650) by [@scutifer](https://github.com/scutifer))
 - Extension example: `notify.ts` for desktop notifications via OSC 777 escape sequence ([#658](https://github.com/badlogic/pi-mono/pull/658) by [@ferologics](https://github.com/ferologics))
 - Inline hint for queued messages showing the `Alt+Up` restore shortcut ([#657](https://github.com/badlogic/pi-mono/pull/657) by [@tmustier](https://github.com/tmustier))
+- Page-up/down navigation in `/resume` session selector to jump by 5 items ([#662](https://github.com/badlogic/pi-mono/pull/662) by [@aliou](https://github.com/aliou))
