Check out docs:

"Starting with GDAL 3.7, this metadata item is no longer used, as the Int8 data type is used for signed bytes."

I see one failing test, but I think it's not related to this change. I think it's related to 1b754d6

FAIL: test_centroid_collect_filter (gis_tests.relatedapp.tests.RelatedGeoModelTest.test_centroid_collect_filter)

I tested with:

@smithdc1 Thanks for the review ⭐

Yes, it's not related I have the same error with GDAL 3.5 and 3.6, will fix it separately.
