 ### Fixed
 - **Webhook Notifications Missing Camera Snapshot** ([#679](https://github.com/maziggy/bambuddy/issues/679)) — Webhook notification providers did not include camera snapshots (e.g. from First Layer Complete notifications), even though providers like Telegram, Pushover, ntfy, and Discord already attached them. The webhook payload now includes a base64-encoded `image` field when a snapshot is available (generic format only, not Slack format). Reported by @Arn0uDz.
+- **Mobile Sidebar Not Scrollable** — On mobile devices with many navigation items, the sidebar did not scroll, making bottom items unreachable. Added overflow scrolling to the nav section while keeping the logo and footer pinned.
+- **User Notification Ruff/Lint Fixes** ([#693](https://github.com/maziggy/bambuddy/pull/693)) — Fixed missing `timezone` import in email timestamp, unused lambda argument, PEP 8 blank line spacing for `mark_printer_stopped_by_user`, and SQLAlchemy forward reference in `UserEmailPreference` model.
