OpenWrt v.21.02.x is TurrisOS (TOS) v6.x. This is in HBL branche and maybe used for daily use (installed on any of my 3 TO and 2 MOX and running like a charm), if you are an experienced user. Yet with Foris and some other implementations, it is not considered stable by the developers. If you want to help switch to HBL and report bugs to gitlab/developers.
OpenWrt v.22.03.x is TOS v7.x and should be in HBD branche (and OpenWrt Master by now in crashlab - @Pepe correct?) .
Please don’t ask for ETA on TOS v.7 when TOS v.6 isn’t available yet
