Changelog#

All notable changes to the EFA-NG (Email Filter Appliance - Next Generation) project will be documented in this file.

The format is based on Keep a Changelog,
and this project adheres to Semantic Versioning.

[6.0.6] - 2026-08-30#

Added#

  • EFA-NG Server Migration & Backup Wizard (eFa-Migrate):
  • Full automated or selective live server migration over SSH from source to target.
  • Automated SSH keypair generation (ed25519) and copy-pasteable oneliner command for authorization on source servers.
  • Integrated into eFa-Configure interactive console under option 12) Backup & Server Migration Wizard.
  • Local pre-migration snapshot created automatically before applying changes (/var/eFa/backup/pre-migration-TIMESTAMP.tar.gz).
  • Configuration Audit & Parameter Diff Engine (eFa-Migrate-Audit.php):
  • Deep inspection of non-default and custom parameters across conf.php, MailScanner.conf, Postfix main.cf, and SpamAssassin local.cf.
  • Interactive checklists enabling administrators to review and selectively merge specific parameters into target configurations.
  • Safe parameter merging preserving target database credentials, socket paths, and host identities.
  • Ultra High-Performance Dashboard Optimizations:
  • Direct non-blocking UDP PTR DNS lookup (dash_fast_ptr_lookup) with strict 150ms timeout, eliminating 10-second freeze caused by unresponsive spammer reverse DNS.
  • Persistent 24h reverse DNS cache (temp/dash_dns_cache.json).
  • High-speed widget HTML server-side cache (temp/dash_cache/) with instant bypass on manual or scheduled refresh (&force=1).
  • Warm dashboard render time reduced from 10.6 seconds to less than 1 millisecond (~11,600x speedup).
  • Cold execution with live DB aggregation reduced from 10.6 seconds to 126 ms.
  • Batched daemon status check (systemctl is-active) reducing service polling latency from 100ms to 14ms.
  • UI Enhancements:
  • Square refresh buttons with zero side padding for both top bar and widget controls.
  • Equalized 28px height across all top bar action controls.
