src/getdatapath.cc
Fixes small memory leak -
17/08/2010 src/lhaglue.f
PDFsets.index
Allows number usage of CT10f3 etc.. and NNPDF20_heraold etc. -
03/09/2010 PDFsets/CT09MC1.LHgrid
PDFsets/CT09MC2.LHgrid
PDFsets/CT09MCS.LHgrid
PDFsets/cteq66alphas.LHgrid

Fixes problem causing these files to fail in the --enable-low-memory mode. -
29/10/2010 src/wraphkn-lite.f
Fixes the problem of the wrong alphas code being called for the HKN sets in the --low-memory-mode causing the progamme to crash. -
11/11/2010 src/wrapacfgpg.f
Parton PDFs for the AFG set were 2x too high. This fixes the problem dividing them (not the gluon) by 2. -
29/11/2010 PDFsets/NNPDF21_100.LHgrid
lhaglue.f
PDFsets.index
The latest NNPDF fit (2.1) including heavy quark effects (100 replicas as=0.119) -
26/01/2011 src/wrapmstw.f
src/wrapmstw-lite.f
Fixes the "NaN" problem for scales q < m_c for the sets with the lowest charm-quark masses m_c = 1.05 GeV and m_c = 1.10 GeV. -

To apply the patches please replace the file in the relevant directory (normally src) and make/make install again (not necessary for grid file replacements).
