At the moment, I can barely update my own code bases to 9.6.x (lots of small problems)

If you have the energy, it would be great if you could write down what problems you ran into

These look primarily like the busywork of bounds bumps, is that right? Perhaps due to some packages not building under 9.6 on some architectures?

There are some toolchain issues too:

• macOS stopped working with brew provided toolchain (that is supposed to work, although some sources say you should use the “system toolchain”)
• FreeBSD bindist (which I built myself) fails with: libHSghc-9.6.5.a: error adding symbols: malformed archive

The other seem mainly to do with streamly, which is why I’m now considering to move away from it: Move away from streamly? · Issue #1051 · haskell/ghcup-hs · GitHub

The issue is the toolchain is that it mixes a clang and gcc based toolchain, not that it’s provided by brew or otherwise.
