Changes
=======
0.18.0 (2019-06-24)
-------------------
This release includes initial support for the evolving OGC API - Features
standard (aka WFS 3), which represents a clean break from the traditional
design patterns of OGC interface specifications. This release also includes
a refactoring of authentication support into a common approach for all parts of the codebase to use.
Thanks to Eric Spitler for this enhanced functionality!
Users are strongly encouraged to use OWSLib via Python 3 as Python 2 support
(Travis, python-six) will be removed in the future.
