OpenWrt 21.02.0 - First Stable Release

Release and security announcements
168

Hi OpenWRT enthusiasts,

I was searching for a couple of hours how to interpret following:

Direct sysupgrade from 18.06 (or earlier) to 21.02 is not supported. To upgrade, you should backup your configuration, install 21.02.0, and then manually re-create your configuration.

In particular: "install 21.02.0", all guides say from original firmware use the "factory" image (this does not match for me, I have 18.06) and the other solution is to upgrade using sysupgrade which leads to the error message. Therefore I propose to elaborate a bit the install versus sysupgrade.

You message linked to a conversation with the problem: linksys-wrt3200acm-21-02-0-rc1-popup-message

Which proposes following solutions:

sysupgrade -Fn /tmp/openwrt-YOUR_DEVICE-sysupgrade.bin

So if this is confirmed (please confirm), I propose to add it to the documentations about the upgrade information for 21.02.

Thanks ! and special thanks to the OpenWRT contributors doing such a great job !
