I plan to update nauty from the 2.6 series to the 2.7 series soon.
The new version is *almost* backwards compatible with 2.6. However,
one member of the optionstruct structure changed size (from 32 bits to
64 bits), so out of an abundance of caution I am going to rebuild all
consumers. The packages to be rebuilt are:
coin-or-Cbc
coin-or-Couenne
gap-pkg-nautytracesinterface
giac
Macaulay2
normaliz
polymake
I have done successful mock builds of all except Macaulay2, which
appears to be suffering from a garbage collector issue. I'm looking
at how to fix that. Once I figure it out, I will start these builds,
with the goal of completing them before the datacenter move starts.
