ShapeOut 2.16.0

The major achievement in this release is the support for mapped basin features. You can read up on basin features in the documentation of dclab (https://dclab.readthedocs.io/en/stable/sec_av_basins/index.html) and Shape-Out (https://shapeout2.readthedocs.io/en/stable/sec_qg_batch_stats.html). In addition, the QuickView panel now highlights the origin of features as described in the documentation (https://shapeout2.readthedocs.io/en/stable/sec_interface.html#quick-view).
