Release Asuswrt-Merlin 3004.388.10 is now available

[RMerlin]

Asuswrt-Merlin 3004.388.10 is now available for legacy devices still on the 388 code branch. The focus of this release is the merge of new GPL, the new Connections tracking page, and the reorganization of the Tools pages.

3004.388.10 (4-Oct-2025)
  - NOTE: For developers, please note that the new default branch
          is now called "main" - it's what was previously the
          3006.102 branch.
          The "master" branch has been renamed "master-old", and
          is no longer actively used.  Due to how the 3006.102
          branch diverged, it was easier to do it this way than
          to fold back 3006.102 on top of master.
          3004.388 remains where 3004.388 models live.

  - NOTE: Due to numerous webui changes, it's recommended to
          force refresh the page after first login, or clear
          your browser cache.

  - NOTE: Asus has made some security related changes.  Password
          requirements are stricter, and UPNP is no longer
          enabled by default.  New password rules were
          slightly loosened for Asuswrt-Merlin, repeating
          characters are still allowed.

  - NEW: Completely redesigned System Log -> Connections page.
           - You can now filter the list
           - You can set the page to auto-refresh itself
           - Public IP addresses can be looked up on
             WhatismyIPaddress.com
           - Local hostnames will be resolved and shown
           - Routed IPv6 connections will be shown

  - NEW: Added Control-D servers to DNS-over-TLS
         presets (dave14305)
  - UPDATED: Merged GPL 388_25523.
  - UPDATED: dropbear to 2025.88.
  - CHANGED: Setting DNS Director to "Router" will now always
             redirect to the router's own IP.  Previously it
             would redirect to the first DNS server configured
             on the DHCP page (which defaults to the router
             itself).
             If you need DNS Director to redirect to an IP
             configured in your DHCP settings, use a Custom DNS
             entry in DNS Director.  This makes it more consistant
             with what the name implies, and was also necessary
             for improved Guest Network support.
  - CHANGED: Replaced netstat-nat by a fork called netstat-nat-ng.
             This fork fixes a number of issues with IPv6 and
             field size.
  - CHANGED: Optimized performance when refreshing the Sysinfo
             page on a network with thousands of tracked
             connections.
  - CHANGED: Modified the Quick Internet Setup wizard so not
             to attempt downloading firmware updates from Asus
             (which would fail anyway).
  - CHANGED: Tools category renamed System Info.
  - CHANGED: Tools -> Other Settings were moved to new tabs
             (Administration -> Tweaks, and
             Traffic Analyzer -> Settings).
  - CHANGED: Moved "Redirect to asusrouter.com" to the new
             Tweaks tab, and moved "Enable JFFS Custom Scripts"
             to the Basic Config section on the System page.
  - CHANGED: Backported Wireless Log hostname retrieval code
             from 3006 (based on IP instead of MAC)
  - FIXED: DNSDirector "Router" mode would not always work properly
           with IPv6 (now uses REDIRECT instead of DNAT, which was
           backported from iptables 1.4.19).
  - FIXED: Additionnal fix for the status frame missing from
           Network Map under certain hostnames.
  - FIXED: CVE-2025-9230 in OpenSSL (backport by RSDNTWK).

Upgraded a AX88U that is a AIMesh node. No issue(s) identifed. Looks good.

Thanks for your hard work and time RMerlin.

Dirty upgraded my RT-AX86U from 3004_388.9_2 ("dirty" because I only disabled Skynet and stopped AdGuard Home before doing the upgrade), update went fine and router rebooted well.
Cleared my browser cache before connecting to Admin Web page, look nice and look like smoother than before.
I read that some optimization and tweaks have been done and can't tell if it is linked, but:

• Before doing the upgrade, I was around 100 MB free RAM
• After the upgrade, I am now at 200 MB free RAM (same addons, no change)

Thank you very much for your work
