ZLD 5.x firmware development status

mMontana

According to this page

https://support.zyxel.eu/hc/en-us/articles/360005438274-Weekly-Firmware-Support-Version-Lab-Version

latest pubblication of Lab Firmware for ZLD 5.x is dated november 2024, 1 month after 5.39P1, roughly 20 weeks ago.

Is there a new way for access Lab Firmwares?
Is Lab Firmware release suspended?
Is Lab Firmware development suspended?
Which is the ETA of the next 5.x release?
Is any EOS date support that Zyxel is willing to share for these devices?

I'd like to report that the community backlashed at the announcement of EOS date for ZLD 4 devices.

I was incorrect, I apologize.

ZLD 5.39P1 seems released at the same time of the latest Lab Firmware Release, WK47.

Hi @mMontana ,

The latest weekly firmware for version 5.39 is 5.39WK10 (2025). However, we recommend users wait for the official 5.40 firmware scheduled for release this April (2025).

These 5.x ZLD devices are expected to reach end-of-life (EOL/EOS) in 2030.

Is there a new way for access Lab Firmwares?
