Concatenation based on `anndata.concat` should now work since v0.3. But this is a new API so please report any issues with it!

The API should come in v0.3. As the `split_by` PR hasn't been merged, the `to_mudata` functionality might be a bit basic but should cover the main use case.

This now works: ```python import jax import numpy as np from mudata import * x = np.array(jax.random.normal(jax.random.PRNGKey(1), (100, 300))) adata = AnnData(x) adata.var["split"] = np.array(jax.random.binomial(jax.random.PRNGKey(1), 1, .5, (adata.n_vars,))) adata.var["split"] =...

Thank you, @racng! As this seems to be a warning, it shouldn't generally stand in the way of adding modalities. So far I see that this warning might be related...

This should be warning-free in v0.3 but please feel free to open a new issue if there's something else we can improve.

v0.3 supports this via `fsspec`, namely this should work: ```python from mudata import read # OpenFile and BufferedReader from fsspec are supported for remote storage, e.g.: mdata = read(fsspec.open("s3://bucket/file.h5mu"))) #...

There's a step in this direction with #24: if the hashes of both row and column indices in the modalities haven't changed, the `.update()` doesn't need to do anything at...

Thanks, there's [this](https://codecov.io/github/PMBio/mudata?branch=master) available from codecov.io now, and I've also added [this workflow](https://github.com/PMBio/mudata/blob/master/.github/workflows/codecov.yml) to update it.

I am not sure this adds a coverage comment in the pull request thread though yet.

This might have already been fixed in `mudata` [v0.2.3](https://github.com/scverse/mudata/releases/tag/v0.2.3), could you give it a try?
