Release v0.2.0 - Notifications, Activity Logging & Cluster Replication 🔔

Release Date: 2026-03-01

🎉 What's New in UpservX v0.2.0

This release focuses on observability, alerting and cluster operations. Every important action on your node is now logged to a structured activity log, critical events trigger instant push notifications via Email or Webhook (Discord, Slack, custom), and the cluster now supports full container and VM replication between nodes.

✨ Highlights

🔔 Notification System

• Email (SMTP) and Webhook (Discord / Slack / custom) push notifications
• Node hostname included in every message — useful in multi-node setups
• 12 per-event toggles: Container create/start/stop/crash/delete, VM create/start/stop/delete, Backup success/failure, System alert
• Rich context per event (image, ports, CPU, memory, backup size/path, error messages)
• New Notifications tab in Settings UI

📋 Structured Activity Logging

• All service modules write to /var/log/upservx/activity.log
• Consistent YYYY-MM-DD HH:MM:SS [TAG] Message format with INFO / ERROR levels
• 174 cluster print() calls now dual-write via _clog() helper

🔁 Cluster Replication

• Replicate Docker containers and KVM VMs between nodes from the Cluster UI
• Full export/import including volumes, disk images, port mappings and environment variables
• Manual trigger per replication entry

🗄️ Persistent Storage Mounts

• Drives mounted via UI are persisted to /etc/fstab with UUID-based identification
• Automatic fstab cleanup on unmount, backup before every modification

🔒 12 Security Fixes

WebSocket shell auth, debug endpoint removal, path traversal (ISO, tarfile, SSH keys), SSRF, exception leak, rate limiting, input validation, shell allowlist, logout bug.
