Dear GAP Forum,

I am pleased to announce that a new release of GRAPE,
version 4.8.2, is available in the newly released GAP 4.10.2.

The main changes in GRAPE 4.8.2 which affect users are: 

- The new version fixes a bug, which had caused a wrong answer to be 
returned for an input complete graph on more than one vertex for the 
functions MaximumClique, MaximumCompleteSubgraph, 
and CliqueNumber.

- A new function, GeneralizedOrbitalGraphs, was added, which returns a list of 
all the simple graphs for which a given transitive permutation group is a group
of automorphisms. 

- Certain efficiency improvements were made to the functions 
Diameter, Girth, GlobalParameters, and IsDistanceRegular.

I highly recommend upgrading to GAP 4.10.2 to include GRAPE 4.8.2.

Regards,
Leonard
