PDL 2.081 has just been released. Notable changes since 2.079:

• Most of PDL::VectorValued has now been incorporated into PDL::Primitive
• Bugfixes including the t_rot one in 683514, and to MatrixOps::inv, conv2d and MatrixOps::identity
• inflateN added
• allow [o] on OtherPars, which helps towards PDL::OpenCV

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.
