[LHAPDF-announce] LHAPDF V5.7.1 released

[Mike Whalley]

Dear LHAPDF user,

We are pleased to announce the release of version 5.7.1 of LHAPDF.  This
can be downloaded as usual from our website:

http://projects.hepforge.org/lhapdf/

or directly at:

http://www.hepforge.org/archive/lhapdf/lhapdf-5.7.1.tar.gz

======================================================================

This release differs from previous releases in that the PDF input grid
files are not bundled with the tarball.

The grid files are obtained either individually or en-mass using the
script "lhapdf-getdata" which is located in the "install-path"/bin
directory after building and installing LHAPDF.

Alternatively the input grids can be downloaded from the SVN repository
at the url  http://svn.hepforge.org/lhapdf/pdfsets/tags/5.7.1.  A link
to this is on the LHAPDF web page.

This release contains several new PDF sets:

MSTW2008(nlo)(nnlo)_asmz (fits for range of alpha_S values + error sets)
HKN (nuclear PDFs)
NNPDF (sub-versions 1.1 and 1.2)

It also has several bug fixes and improvements since the last release,

These can be viewed in the ChangeLog on the lhapadf web site:
