All modules that call a Unix library contain WoW64 thunks to enable calling the 64-bit Unix library from 32-bit PE code. This means that it is possible to
run 32-bit Windows applications on a purely 64-bit Unix installation. This is called the new WoW64 mode, as opposed to the old WoW64 mode where 32-bit applications run inside a 32-bit Unix process.
Old Proton builds probably won’t backport this (unless it’s completely isolated, idk the code layout of Wine). But are old Proton builds still necessary? Occasionally there’s regressions, but are there really any games that require like a 2 year old Proton build?

So in the future no need to install 32 bit packages of wine in a 64 system??? 👀
Correcto. Which means Steam will probably drop 32 bit libs soon. Which means Ubuntu will stop shipping 32 libs. The era is truly coming to an end
Let’s call it “soonish”. The old proton versions still need 32 bit libs if they do not backport the feature.
