Changes of Note

Python support now requires at least version 3.5+ of Python and version 1.13 of Numpy.
filters.icp is no longer a plugin and provides options not previously available.
Linear algebra that was using single-precision math is now using double-precision math.
Support was added for GDAL version 3+.
PCL support has been removed. PCD read/write and filters.icp is now natively supported. The PCL filters have been moved to the unsupported-plugins repository for those that might need functionality they provided.
PDAL now uses a JSON library that doesn't support comments. If your pipelines contain non-standard JSON, they will no longer be accepted.
PDAL now supports GCC 9.2, clang 8.0.1 and Visual Studio 17

filters.covariancefeatures computes statistics about features of points in a neighborhood. (#2455 - Thanks Helix.re!)
readers.e57 reads the E57 format. (#2442 - Thanks Helix.re!)
writers.e57 writes the E57 format. (#2442 - Thanks Helix.re!)
writers.gltf provides simple glTF mesh output support. (#2643)
filters.reciprocity computes the percentage of points that are considered uni-directional. (#2504 - @chambbj)
filters.miniball computes a criterion for neighbors based on the miniball algorithm. (#2504 - @chambbj)
filters.planefit computes a deviation of a point from a manifold approximating its neighbors. (#2504 - @chambbj)
readers.memoryview provides an API interface for direct reading of row-oriented point data. (#2620)
filters.projpipeline processes point through a PROJ pipeline. (#2626 - Thanks @vilaa!)

readers.mrsid now supports more recent versions of the Mr. Sid SDK. (#2460)
readers.tiledb and writers.tiledb now support stream mode processing. It also supports an append option.
readers.ept now accepts an optional \<spatial reference> after the bounds specification in the bounds option to indicate the SRS of the provided boundary. (#2295)
filters.hag now supports interpolation from a TIN (triangulated network) of points. (#2520 - Thanks James McClain!)
filters.poisson now properly applies an inverse transform to points it creates. (#1840)
pdal --drivers now shows the file extensions associated with each driver. It also shows when stages are streamable. (#2571, #2528)
Some threaded execution has been added to readers.ept.
Alternate dimension names have been added for "Red", "Green" and "Blue" to better support PLY input. (#2570)

Fixed a problem where data in a forwarded LAS VLR would be lost. (#2542)
Clear dimension list in filters.colorization to eliminate the possibility of writing invalid data. (#2487)
Delete code that removed control characters when converting to JSON. (#2355)
Fixed an issue where nested geometries were being written as invalid WKT in filter.hexbin. (#2507)
Fixed a segmentation fault in readers.bpf if the specified file didn't exist. (#2515)
Fixed an issue in writers.gdal where interpolation would terminate if the process hit the raster edge. (#2545)
Fixed an issue writing JSON when characters needed to be escaped. (#2558)
Delaunay triangulation no longer segfaults with fewer than three points. (#2513)
Issues with reading binary data with filters.ept have been fixed. (#2585)
pdal now errors if an option is provided that wasn't expected. (#2574)
Forwarding for scale with multiple LAS inputs was fixed. (#2663)
