The repro does not say released against the 1.0.4/1.1.1 - and in fact says there are one active branches (sic) and goes on to list three, so YMMV.
The issue here is the body of collective knowledge - if you want to go Chris Columbus and explore new territories, that’s great, but it will leave you figuring some stuff out alone.
Plus 1.0.4 requires us to track the DevNonce - there’s lots of little subtle changes - so navigation can need more than no map and just a sextant.
