Gregory's ServerGeoPandas has released an alpha of v1.0.0 - time to check it works with your code.
Details at https://martinfleischmann.net/geopandas-1.0-is-coming.-what-will-change/, changes include switching default loader from fiona to pyogrio (nice! I often forget to use pyogrio and it'll save me time), requiring Shapely 2.0, removing built-in datasets, and deprecating some stuff.
