+# Easy Asterisk - Interactive Installer v1.25
 #
-# UPDATES in v1.24:
+# UPDATES in v1.25:
+# - QUICK LOCAL SETUP: New recommended installation path (90% use case)
+#   * One-click local network setup
+#   * PTT with mute-by-default
+#   * Auto-answer for kiosks
+#   * Audio ducking
+#   * No COTURN/internet/certificates needed
+#   * Perfect for intercoms, warehouses, offices
+#
+# - VPN DETECTION: Automatic VPN interface detection
+#   * Detects Tailscale, WireGuard, OpenVPN
+#   * Offers to bind Asterisk to VPN IP
+#   * Shows benefits of VPN vs COTURN
+#   * Stores VPN config (USE_VPN, VPN_INTERFACE, VPN_IP)
+#
+# - SIMPLIFIED COTURN GUIDANCE: Crystal-clear when you need it
+#   * Shows "Do you ACTUALLY need COTURN?" with examples
+#   * ✗ DON'T need: Local network, VPN, simple NAT
+#   * ✓ DO need: Symmetric NAT, VLAN isolation, corporate firewall
+#   * Changed default prompt from [Y/n] to [y/N] (opt-in not opt-out)
+#
+# - TURN DOMAIN: Defaults to SIP domain (same domain is fine!)
+#   * TURN_DOMAIN defaults to DOMAIN_NAME
+#   * Explains single vs separate domain options
+#   * Warns if using separate domains about cert coverage
+#
+# RETAINED from v1.24:
 # - COMPREHENSIVE: Complete OPNsense/pfSense VLAN configuration guide
 #   * Full network topology documentation (LAN + VLAN 20/30/40)
 #   * Step-by-step firewall rules for VLAN isolation
