### [`v5.4.0`](https://github.com/sahara101/Movie-Roulette/releases/tag/v5.4.0)

[Compare Source](https://github.com/sahara101/Movie-Roulette/compare/v5.3.0...v5.4.0)

#### New Features

- **Watch Together - Watchlist & Library modes** (Plex only) - find movies to watch with a partner via two modes: **Watchlist** (intersects plex.tv watchlists, no app account needed) or **Library** (intersects local watch-status caches, instant). Enable via `PLEX_WATCH_TOGETHER=true` or Settings -> Plex
- **Multi-arch Docker manifest** - `latest` and version tags are now multi-arch manifests (AMD64, ARM64, ARMv7). `arm-latest` kept for backward compatibility
- **Filter panel redesign (HeroUI)** - filter is now a full-height right sidebar on desktop and a bottom-sheet on mobile, with open/close animations and an active-filter-count badge (or **W** for Watch Together)

#### Security

- **cbor2 -> 5.9.0** (CVE-2026-26209, high) - DoS via uncontrolled recursion in `cbor2.loads()`; affects WebAuthn/Passkey flow
- **requests -> 2.33.0** (CVE-2026-25645, medium) - insecure predictable temp filename in `extract_zipped_paths()`

#### Bug Fixes

- **Plex managed/home user cache not building** - resilient fallback chain (`switchUser()` -> `switchHomeUser()`) handles Plex CVE-2025-34158 / CVE-2025-69417 endpoint restriction
- **Empty cache file suppressing rebuilds** - cache build now also triggers when the file exists but is <= 2 bytes
- **Slow search** - queries local cache instead of media server API; drops from \~3-10 s to <50 ms; debounce reduced to 150 ms
- **Search modal uncloseable on mobile/PWA** - uses centered modal with tappable backdrop on mobile
- **Watchlist pool stall (3-5 s) after reset** - TTL is now sliding with 15-minute idle timeout instead of fixed 5-minute expiry
- **"All movies seen" toast missing in HeroUI** - pool reset surfaced in Watch Together response; toast uses glassmorphism styling
- **Filter close animation missing on mobile (HeroUI)** - bottom-sheet now slides down correctly instead of using the desktop keyframe
- **Update notification wrong theme on main page** - `heroui-theme.css` and `aceternity-effects.css` now loaded in HeroUI main page block
- **Login card off-center on mobile** - switches to `justify-content: center` at <=480px
- **Collection warning x button visible on mobile** - hidden at <=480px across all stylesheets
- **User Management usernames hidden on mobile** - scoped hide rule to `.user-item .user-name` to avoid conflict with `auth.css`

**Full Changelog**: <https://github.com/sahara101/Movie-Roulette/compare/v5.3.0...v5.4.0>
