= 2.2.0 =
**Major Update: Queue-Based Architecture**
* NEW: Database-backed email queue for persistent, reliable email delivery.
* NEW: External CLI worker script for asynchronous email processing.
* NEW: Queue Status widget showing real-time statistics (pending, processing, sent, failed).
* NEW: Recent Campaigns section with key metrics in settings page.
* NEW: Email Queue admin page to view all queued and sent emails.
* NEW: Statistics admin page with campaign performance metrics.
* NEW: Parallel worker support for high-volume sending (10+ workers simultaneously).
* NEW: Automatic retry with exponential backoff (up to 3 attempts: 5min → 15min → 30min).
* NEW: Campaign statistics tracking (start time, duration, speed, success rate).
* CHANGED: Emails are now queued to database instead of sent immediately.
* CHANGED: Settings page reorganized with Queue Status, Recent Campaigns, and Worker Configuration sections.
* CHANGED: Campaign statistics now grouped by unique Newsletter ID instead of campaign name.
* REMOVED: max_per_connection setting (no longer needed with worker architecture).
* REMOVED: Direct PHPMailer usage (replaced with wp_mail() in workers).
* FIXED: Duplicate campaign statistics for campaigns with same name but different IDs.
* FIXED: Worker command documentation (corrected parallel worker syntax).
* BREAKING: Manual worker setup required - emails no longer send automatically.
* BREAKING: System cron or process supervisor required for production use.
* Technical: New database tables for queue and statistics with automatic creation on activation.
* Technical: Microsecond precision timestamps for accurate performance metrics.
* Security: CLI-only worker script with SQL injection prevention and capability checks.
= 2.1.0 =
* Changed uninstall behavior: plugin no longer performs cleanup on uninstall, all data cleanup is now handled by the core SMTP plugin.
