Fiona

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

New features:

* Add listdir and listlayers method to io.MemoryFile (resolving 754).
* Add support for TIN and triangle geometries (1163).
* Add an allow_unsupported_drivers option to fiona.open() (1126).
* Added support for the OGR StringList field type (1141).

Changes and bug fixes:

* Missing and unused imports have been added or removed.
* Make sure that errors aren't lost when a collection can't be saved properly
(1169).
* Ensure that ZipMemoryFile have the proper GDAL name after creation so that we
can use listdir() (1092).
* The fiona._loading module, which supports DLL loading on Windows,
has been moved into __init__.py and is no longer used anywhere else (1168).
* Move project metadata to pyproject.toml (1165).
* Update drvsupport.py to reflect new format capabilities in GDAL 3.6.0
(1122).
* Remove debug logging from env and _env modules.

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

Packaging:

* Builds now require Cython >= 0.29.29 because of
* https://github.com/cython/cython/issues/4609 (see #1143).
* PyPI wheels now include GDAL 3.5.2, PROJ 9.0.1, and GEOS 3.11.0.
* PyPI wheels are now available for Python 3.11.

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

Deprecations:

- Fiona's API methods will accept feature and geometry dicts in 1.9.0, but this
usage is deprecated. Instances of Feature and Geometry will be required in
2.0.
- The precision keyword argument of fiona.transform.transform_geom is
deprecated and will be removed in version 2.0.
- Deprecated usage has been eliminated in the project. Fiona's tests pass when
run with a -Werror::DeprecationWarning filter.

Changes:

- Fiona's FionaDeprecationWarning now sub-classes DeprecationWarning.
- Some test modules have beeen re-formatted using black.

New features:

- Fiona Collections now carry a context exit stack into which we can push fiona
Envs and MemoryFiles (1059).
- Fiona has a new CRS class, like rasterio's, which is compatible with the CRS
dicts of previous versions (714).

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

Deprecations:

- The fiona.drivers() function has been deprecated and will be removed in
version 2.0. It should be replaced by fiona.Env().
- The new fiona.meta module will be renamed to fiona.drivers in version 2.0.

Packaging:

- Source distributions contain no C source files and require Cython to create
them from .pyx files (1096).

Changes:

- Shims for various versions of GDAL have been removed and are replaced by
Cython compilation conditions (1093).
- Use of CURL_CA_BUNDLE environment variable is replaced by a more specific
GDAL/PROJ_CURL_CA_BUNDLE (1095).
- Fiona's feature accessors now return instances of fiona.model.Feature instead
of Python dicts (787). The Feature class is compatible with code that
expects GeoJSON-like dicts but also provides id, geometry, and properties
attributes. The last two of these are instances of fiona.model.Geometry and
fiona.model.Properties.
- GDAL 3.1.0 is the minimum GDAL version.
- Drop Python 2, and establish Python 3.7 as the minimum version (1079).
- Remove six and reduce footprint of fiona.compat (985).

New features:

- The appropriate format driver can be detected from filename in write mode (948).
- Driver metadata including dataset open and dataset and layer creations
options are now exposed through methods of the fiona.meta module (950).
- CRS WKT format support (979).
- Add 'where' SQL clause to set attribute filter (961, 1097).

Bug fixes:

- Env and Session classes have been updated for parity with rasterio and to
resolve a credential refresh bug (1055).

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

Builds now require Cython >= 0.29.29 because of
https://github.com/cython/cython/issues/4609 (#1143).

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

Changes:

- Driver mode support tests have been made more general and less susceptible to
driver quirks involving feature fields and coordinate values (1060).
- OSError is raised on attempts to open a dataset in a Python file object in
"a" mode (see 1027).
- Upgrade attrs, cython, etc to open up Python 3.10 support (1049).

Bug fixes:

- Allow FieldSkipLogFilter to handle exception messages as well as strings
(reported in 1035).
- Clean up VSI files left by MemoryFileBase, resolving 1041.
- Hard-coded "utf-8" collection encoding added in 423 has been removed
(1057).
