laserchicken - v0.4.2
This release includes:
* an improvement in the performance of spatial filtering;
* some changes in how multipolygons are dealt with in spatial filtering;
* a bug fix in the copy_point_cloud function.

laserchicken - v0.4.0
This releases introduces several improvements and functionalities, among which: - a simplified structure for the computed neighborhood list; - additional IO tools, which make laserchicken able to read and write LAZ and binary PLY files; - utility functions to merge point clouds, update point-cloud features and classify points on the basis of polygons.
Some refactoring has also been performed to improve the code organization. For the complete list of changes, have a look at the CHANGELOG

laserchicken - v0.3.2
This release introduces feature extractors that work on the intensity attribute of points. Many feature extractors have been restructured and are now parameterized meaning that they can do their computation on an arbitrary input attribute. Because of this restructuring, and for consistency purposes, many features have been renamed. See the CHANGELOG for a list of these.

laserchicken - laserchicken v0.1.1
Added tests and many bug fixes. These are mostly fixes for corner cases in feature extractors. For instance some feature extractor used to crash when they were processing a point cloud with zero points. This has been solved for every feature extractor.
