PDL 2.078 has just been released. Notable changes since 2.077:

• TriD::GL now more resilient and exceptions don't leave GL broken
• Bugfixes including to NiceSlice
• demo 3d now shows off a 3D Earth (with accurate shading), and also a 3D molecule-like graph evolving over time
• The pdl struct now has room for a single value (or if not complex long double, several values of smaller datatypes), avoiding extra memory-management for small ndarrays – but you don’t need to recompile installed modules

The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask questions, or just watch the GitHub messages flow by.

Please give the new PDL a try and report problems.
