fiona 1.10b3

on Python PyPI

Bug fixes

• The sketchy, semi-private Python opener interfaces of version 1.10b2 have been replaced by ABCs that are exported from fiona.abc (#1415). How to implement the interfaces and provide a custom opener is documented in test_pyopener.py and will be included in the documentation for version 1.10.0.
• The truncate GDAL VSI plugin callback has been implemented (#1413).

Please see the CHANGES file for a more detailed enumeration of changes since version 1.9.6. Unless showstopper bugs are found in this release, expect a release candidate in two weeks.
