Fiona

-------------------

Packaging:

- Wheels include GDAL 3.2.1 and PROJ 7.2.1.

Bug fixes:

- In fiona/env.py the GDAL data path is now configured using set_gdal_config
instead by setting the GDAL_DATA environment variable (1007).
- Spurious iterator reset warnings have been eliminatged (987).

-------------------

- The precision option of transform has been fixed for the case of
GeometryCollections (971, 972).
- Added missing --co (creation) option to fio-load (390).
- If the certifi package can be imported, its certificate store location will
be passed to GDAL during import of fiona._env unless CURL_CA_BUNDLE is
already set.
- Warn when feature fields named "" are found (955).

-------------------

- To fix issue 952 the fio-cat command no longer cuts feature geometries at
the anti-meridian by default. A --cut-at-antimeridian option has been added
to allow cutting of geometries in a geographic destination coordinate
reference system.

-------------------

- More OGR errors and warnings arising in calls to GDAL C API functions are
surfaced (946).
- A circular import introduced in some cases in 1.8.15 has been fixed (945).

-------------------

- Change shim functions to not return tuples (942) as a solution for the
packaging problem reported in 941.
- Raise a Python exception when VSIFOpenL fails (937).

-------------------

- When creating a new Collection in a MemoryFile with a default (random) name
Fiona will attempt to use a format driver-supported file extension (934).
When initializing a MemoryFile with bytes of data formatted for a vector
driver that requires a certain file name or extension, the user should
continue to pass an appropriate filename and/or extension.
- Read support for FlatGeobuf has been enabled in the drvsupport module.
- The MemoryFile implementation has been improved so that it can support multi-part
S3 downloads (906). This is largely a port of code from rasterio.
- Axis ordering for results of fiona.transform was wrong when CRS were passed
in the "EPSG:dddd" form (919). This has been fixed by (926).
- Allow implicit access to the only dataset in a ZipMemoryFile. The path
argument of ZipMemoryFile.open() is now optional (928).
- Improve support for datetime types: support milliseconds (744), timezones (914)
and improve warnings if type is not supported by driver (572).
- Fix "Failed to commit transaction" TransactionError for FileGDB driver.
- Load GDAL DLL dependencies on Python 3.8+ / Windows with add_dll_directory() (851).
- Do not require optional properties (848).
- Ensure that slice does not overflow available data (884).
- Resolve issue when "ERROR 4: Unable to open EPSG support file gcs.csv." is raised on
importing fiona (897).
- Resolve issue resulting in possible mixed up fields names (affecting only DXF, GPX,
GPSTrackMacker and DGN driver) (916).
- Ensure crs_wkt is passed when writing to MemoryFile (907).
