It is my pleasure to announce the release of PDAL 1.4.0. Numerous features, bug fixes, and enhancements have been added since the 1.3.0 release in August. I would like to especially thank Andrew Bell and Brad Chambers for their significant enhancements to this release. Andrew coordinated the development of 'writers.gdal', which is a much more flexible points2grid replacement that does not require any external library. Brad refactored many of the PCL-dependent filters into stock PDAL ones, and he added a ton more capability for those looking to use PDAL in algorithm processing chains.
PDAL 1.4.0 also significantly enhances other language extensions with a preview Java/JNI binding by Rob Emanuel and Grisha Pomadchin of Azavea, and a significant refactor of the Python extension https://pypi.python.org/pypi/PDAL
