By means of the opkg package management system there is the possibility to determine for yourself what the router can and cannot do. Also on GoT there are several people actively working on it, see this topic. You can simply update the version with sysupgrade from the web interface.

- Device support: images for some device became too big to support a persistent overlay, causing such devices to lose configuration after a reboot. If you experience this problem, please report the affected device in the forum and consider downgrading to OpenWrt 18.06 or using the Image Builder to pack a smaller custom image
- Device support: conversely, certain images for devices with small flash (4 MB) are no longer built for the release
