v2.9.0 — Media Server Analytics, Notifications, Library Cleanup, Hunting Overhaul & Runtime Validation

The largest feature release since 2.0 — adding media server awareness, a full notification system, library lifecycle management, and a comprehensive hunting overhaul.

Highlights

🎬 Plex/Tautulli Integration

• Now Playing dashboard with live session monitoring
• On Deck & Recently Added poster carousels
• Watch history with user attribution
• Session snapshot analytics (bandwidth, transcode, device trends)

📬 Notification System (10 Channels)

Discord, Slack, Telegram, Email, Gotify, Ntfy, Pushover, Webhooks, Browser Push, Apprise — with event subscriptions, routing rules, aggregation batching, and retry with dead-letter tracking.

🧹 Library Cleanup

Rule-based evaluation (size, quality, age, codec, watch status) with approval workflow, dry-run preview, and circuit breaker safety.

📺 Jellyseerr/Overseerr Integration

View, approve, and decline media requests directly from the dashboard with CSRF handling and circuit breaker resilience.

🔍 Hunting Overhaul (#187)

• Fetches complete wanted list (up to 10K items) — fixes dead-page pagination bug
• "Include all monitored items" toggle for upgrades after quality profile changes
• Diagnostic funnel messages: "Fetched 500 → 320 passed filters → all 320 recently searched"

✅ Runtime Validation

Zod validation on all upstream API responses with schema drift detection, quarantine ring buffer, and health dashboard.

🎨 UI Consistency

Three-tier card system, backdrop-blur cleanup, light/OLED mode fix, form input standardization across 53+ files.

⚡ Performance

• Batched Plex cache upserts (10-50x faster on RPi/NAS)
• Database indexes for analytics queries
• Smart polling (disabled on inactive tabs, reduced intervals)
• ColorThemeProvider memoization, NavContent module-scope, lazy-loaded modals

🔒 Security

• 11 CVEs resolved (next 16.1.7, undici 7.24.0, flatted 3.4.0)
• SSRF prevention in Plex image proxy
• 6 silent failure catch blocks now log errors
• Comprehensive security review completed

Upgrade Notes

• SQLite & PostgreSQL: Both upgrade paths tested and verified with data preservation.
• Breaking Changes: None. All existing configurations are preserved.
• Docker: Pull khak1s/arr-dashboard:latest and restart.
