    Hi @mMontana

    Since the firmware V5.41 just released, may I know the reason you want to know the next firmware release date?

    At date of writing I was not aware of version 5.41 published the day before.
    After your post, I knew it was available and I expedited update due to CVE resolved into release.

    Still the question remains. :)
    Knowin in precedeing time the availability of the updates ease the maintenance window planning. Due its role, firewalls are most of time critical devices to update: most of the times a vulnerability is solved.

    Hi @mMontana

    Fortunately, I have received the schedule for the upcoming firmware release, which is scheduled for Q1 2026. However, the timeline for the subsequent firmware release has not yet been established, and therefore, I am unable to provide additional details at this time.

    @Zyxel_Melen I'd love to say "thanks to the shared info from tech department", not pure luck.

    And anyway, thanks for sharing. Is not the most precise date but I understand that close to a release the future "deadline" could be adjusted several times.

    I hope that Zyxel will improve, in coming months, the capability to schedule and adhere to deadlines, for allowing scheduling of maintenance windows.

    I mean… almost any CVE on perimeter is a ticking alarm to be snoozed ASAP before issues.
