Version 1.9.4 has important bug fixes and improvements and, in the PyPI wheels, updates GDAL to 3.6.4.
- The performance of Feature.from_dict() has been improved (#1267).
- Several sources of meaningless log messages from fiona._geometry about NULL geometries are avoided (#1264).
- The Parquet driver has been added to the list of supported drivers and will be available if your system's GDAL library links libarrow. Note that fiona wheels on PyPI do not include libarrow as it is rather large.
- Ensure that fiona._vendor modules are found and included.
- Bytes type feature properties are now hex encoded when serializing to GeoJSON (#1263).
- Docstrings for listdir and listlayers have been clarified and harmonized.
- Nose style test cases have been converted to unittest.TestCase (#1256).
- The munch package used by fio-filter and fio-calc is now vendored and patched to remove usage of the deprecated pkg_resources module (#1255).
