6.12 is is latest tag, but also include one fix past that, v923z/micropython-ulab#750, which is meant to be 6.12.1 but hasn't been released yet.

FYI @v923z

ulab: disable ndarray modulo and scipy.integrate to reduce build size
be87246 
The 6.12 ulab update added the ndarray % operator (~3.9kB) and a new
scipy.integrate module (~4.0kB), pushing size-constrained boards over.
Disable both by default.

The scipy.integrate disable is groundwork: ULAB_SCIPY_HAS_INTEGRATE_MODULE
does not yet drop the module's code upstream (the flag only gates the scipy
namespace entry). It becomes an actual size win once the upstream ulab fix
lands and the submodule is bumped.

No, sorry, there are several issues and pull requests in ulab that haven't been acted on, including failing tests. I can push this forward later, forking if needed. Or I will submit easy PR's to approve.

Which are the critical bugs that should be fixed?

Hi @v923z: v923z/micropython-ulab#753 and v923z/micropython-ulab#755 should be addressed. See v923z/micropython-ulab#756 as well. The tests are failing without those, so we can't upgrade as is.

You talked about using isclose() v923z/micropython-ulab#755 (comment), and I had a mind to do that across all the tests with an LLM, but haven't gotten to it.

I've merged the first PR, the second is a draft. You're right, isclose would be the right fix, but I'd be OK with merging v923z/micropython-ulab#755.

@v923z Thank you! I'm going to submit a PR is just the break vs. continue fix in v923z/micropython-ulab#755. That will not pass tests, but it will set the stage for an isclose() PR, which I'll then have an LLM do.
