PDL 2.079 has just been released. Notable changes since 2.078:

• Badflag propagation is much more automatic, as well as fixing a long-standing bug in it if type-conversion of a parameter happened - see https://github.com/moocow-the-bovine/PDL-CCS/pull/5 for more
• PDL::Dataflow doc brought up to date
• PDL::IO::STL added to read 3D-printable items from e.g. Thingiverse
• PDL::Graphics::TriD::trigrid3d completed from a 2000-era prototype which can display the above or other “indexed face-set” type content
• A long-standing bug that affected Windows with parallel processing has been fixed (see 11116094 for more - thanks marioroy for the report!)
• PDL::Image2D::crop added (see 11143251 for more)

Future plans, in something like intended order:

• Restructure the TriD stuff so there is a consistent API between OpenGL and X3D/VRML - see 11143037 for more
• fix more open GitHub issues
• add event-handling hooks for ndarrays - see PDL::Dataflow for more
• finish the independent C interface for making PDL usable from e.g. Python - see https://github.com/PDLPorters/pdl/issues/358 for more
• “loop fusion” techniques to maximise locality of computation, minimising data’s trips through the “straw” between CPU and main RAM
• use OpenCL or other means to also utilise GPUs if available - see https://github.com/PDLPorters/pdl/issues/349 for more on this and the above

Please give the new release a try and report problems.
