- HTTPS on 8443 – Management interface now served over TLS by default.
- UPnP Disabled – Universal Plug and Play starts in the off state for reduced surface exposure.
- AiCloud Authentication Hardening (CWE-287) – Added layered verification.
- Authentication Logic Refactor – Removed redundant code paths for a lean sign-in flow.
- Memory Safety Guard (CWE-476) – Introduced null-reference protections across critical services.
- Enhanced IPsec Parameter Validation – The existing input checks have been hardened.
- Data Exposure Mitigation (CWE-200) – Reinforced controls on sensitive pathways.
- Detailed Audit Trails – Expanded logging within the authentication module.

System Improvements
- Connection Stability – Core algorithms refined for steadier links.
- Scheduling Accuracy – Timed tasks execute reliably under PPPoE, PPTP and L2TP WAN modes.
- Client List Maintenance – Resolved an issue that prevented offline devices from being removed from the client list.

I've never ever done that after updating firmware. I have like 20+ DHCP assignments I make, and I assume they would be lost. Is it permissible to load a saved configuration file to restore them, or would that defeat the purpose of the factory reset?

Is it permissible to load a saved configuration file to restore them

I don't think anyone here can answer that with certainty, and probably no one will be able to understand exactly which changes might be undone by restoring a configuration backup. I personally would be very reluctant to perform a factory reset on all my XT8 Mesh devices, but given the various security changes, it seems necessary in this case. Otherwise, Asus probably wouldn't have pointed this out so explicitly.

Since I don't use my Asus XT8 as a router but only as an access point in the LAN, I don't really see any urgency in doing the update.

I have never ever reset my router (any of them in 25 years), after an update, and I'm not going to do it (too much time setting all again).

And... suppose yo have "auto update" set. If I do not read Asus support page, I would no know there is an update nor the advice to reset.

I upgraded and it slowed my internet connection down to 1Mbps, I generally have 300+Mbps. I called Asus and they escalated the ticket, so I'm just waiting now. I tried downgrading to the previous firmware and it did NOT fix the issue so who the heck knows. Maybe a factory reset would help but I'm not in a hurry to do that right now as I'm headed out of town for two weeks. I've definitely disabled auto-updates after this though.

That's brutal. I was wondering if anyone had installed it yet to check if this release is stable or not. I have three XT8s in a wireless backhaul mesh: two V1s and one V2. I'm having very good luck on 24710, so I'm hesitant to upgrade, especially considering ASUS recommends a full factory reset to activate all the new security features.

Installed some minutes ago. My 300 ftth (DIGI Spain) is performing as usual:

Did you did the factory reset on the settings?
