PDL::Delta - PDL changes between V1.0 and V2.0

ndarraysarenothashesanymore:
           $x = zeroes 10,10;
           $$x{FOO} = "bar"

       doesn't work. They are currently scalar references (to opaque C structures in finer terms) because of
       speed as well as syntactic issues. If you want to have a hash, use

           $x->hdr()

       which returns a reference to an anonymous hash. Also, subclassing works if you store an ndarray in the
       hash member ``PDL''.

       There are also many core enhancements to support Dataflow and Slicing tricks, but these do not introduce
       any incompatibilities.

           Order of the arguments has changed.

       copy method
           No longer copies the header. This may not be a misfeature.

       This file is an attempt to list the major user-visible changes between PDL versions 1.0 and 2.0.

       Many of the base and library pods were updated.

       pdldelta was inspired by perldelta  man page in the Perl 5.004 distribution.
