Yes, this is a miss. The package is still there, it's just not exported in pyproject.toml. I'll also have to check why the tests didn't flag this.
@danielballan Thanks for the report. We'll get this back into v1.4.1.

The package is working again on my branch, but I seem to have hit a little snag with the adbc-driver-manager on Windows which makes my tests fail in CI.
The tl;dr is this:
adbc_get_objects(depth="all").to_pylist()returns an a list of catalog dicts that, only on Windows, have an empty string where the keycatalog_namekey is supposed to be. Example catalog dict from the test output:I'm expecting this:
The tests run fine in CI on Windows and OSX, but they fail on Windows.

I'll merge the fix today, should be working again starting with the next 1.4.1 nightly (not the 1.5.0 nightly yet).
There might be an unrelated issue with the adbc-driver-manager on Windows. I'll keep an eye on that, and if it turns out this is an issue on our end I'll fix it. In any case that is a different issue than this.
