The old 432 infoboxes are a bit vague about the "limitations" of 432 devices.
Time for an update and to make certain things crystal clear to the readers of the wiki.
Goals of the new 432 infoboxes:
make clear, that 4/32 devices should not be bought any more for using them with up-to-date OpenWrt (18.06 onwards)
make clear, that “limited” can mean that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless
make clear that 19.07 will be the last official build for 4/32 devices . After 19.07, no further images will be built for 4/32 devices, i.e. you have to build your own image with the known space saving measures
Feel free to edit https://openwrt.org/inbox/infobox/432_infobox_new so the NEW infoboxes meet the goals shown at the beginning of this page.
Once we agree on a good wording, I will implement the new infoboxes for productive use.
