I have made a minor release of nauty, version 2.4r1.  The changes are:

* The sort command used by shortg now uses the modern way (-k) of
  specifying keys instead of the old way, unless the modern way is
  not available.

* Procedure getline() is renamed to gtools_getline() to avoid a 
  clash with the GNU library function getline().

* Invariants cellinv() and cellcliq() had bugs, now fixed.

* Procedures getecline() and writepc_sg() had bugs, now fixed.

The last four mentioned procedures were not used by default in
any distributed software.

A major new release of nauty is coming up soon.
