I have a peplink 20x. Is there any way to get an alert/notification by e-mail, text, etc when new firmware is released, or if there are critical security fixes available? Or… back to the old check-each-month method?
You can try to subscribe to the “announcement” category so when there is a new announcement (eg. new firmware release), you will be notified. You can choose the category to subscribe by going to your profile (your icon, top right) > User Preference > Settings > CATEGORIES > Watching First Post.
You can check out the Security Advisory from the Support section.
