And should appear at a mirror near you soon.
This release has the usual polishing and bugs fixed
but the highlight is completed support for 64bit
integers as PDL_Indx type.Thanks to the many developers
and users whocontributed to make this release possible.
Enjoy and happy PDL-ing!

General Notes:
* This is PDL-2.014 introducing full support for
64bit indexing operations using 64bit PDL_Indx
data type.
* PDL can now create and use piddles having more
than 2**32 elements. Of particular use is that
you can now use PDL::IO::FlexRaw to memory map
piddles from files on disk which can allow for
simplified processing and IO on extremely large
data.
* Due to the new PDL_Anyval type changes, existing
PDL::PP modules may need to be updated to support
the new PDL Core version 12 API. Authors, please
see PDL::API for macros to ease the porting.
Users, be aware that some modules may not work
until they are updated by their maintainers.
Highlights:
* Implement PDL_Anyval data type as union to support
64bit indexing
This adds a union data type to add 64bit integer support to
the original PDL-2.x types which assumed that double was
capable of holding all the "lesser" types. With the PDL_Anyval
type, we can correctly handle 64bit integer data types and
avoid errors and loss of precision due to conversions to or
from PDL_Double. Special thanks to kmx and zowie for their
help to complete and debug this implementation.
* Many fixes to the build process to make PDL more robust
to build, test, and install. This takes advantage of new
automated CI testing via Travis CI on the github site.
Thanks much to Ed and Zakariyya for their work to get
this started and maintained. This CI testing makes
this the best tested and best testing PDL release ever!
* Various documentation clean-ups and work to improve
on-line viewing at http://metacpan.org and others.
(Thanks kmx and Derek!)
* A new ipow() method haw been added with 64bit integer
support. ipow() calculates the integer exponentiation
of a value by successive multiplications. This allows
one to avoid loss of significance in integer exponents.
pow() converts the value to double and will always have
<52bits precision.
* nbadover and ngoodover now return indx type (PDL_Indx)
* PDL now detects when your perl installation has been
built with floating point longer than 8 bytes and gives
a one time warning that precision will be lost converting
from perl NV to PDL_Doubles. This warning is given on
"use PDL;"
* "use PDL" now includes "use PDL::IO::Storable"
This avoids a hard to diagnose crash that can
occur when a user tries using Storable without the
necessary "use PDL::IO::Storable".
* MANY sf.net bugs fixed:
400 dataflow slice crash around 2**31 boundary
