Changes in version 2.1.1:

• Updated data from the ATLAS project
• The new function EvaluatePresentation computes the images of the relators of a presentation
• The new function StandardGeneratorsData allows one to compute standard generators from given generators, provided a recipe for that task (a find straight line program) for the group in question is available.
• The function AtlasGroup sets known information about the group and the representation, such as IsPrimitive. (Thanks to Steve Linton for suggesting this feature.)
• The function ResultOfBBoxProgram now admits an optional argument, which is used as options record in calls to RunBBoxProgram.
• The new user preference AtlasRepJsonFilesAddresses allows one to use Json format data files for matrix representations in characteristic zero, which in turn makes it possible to create the matrices over prescribed fields, for example fields returned by AlgebraicExtension. The information stored in the table of contents file about the field of entries of the matrix representations has been extended by a GAP independent description of this field and the defining polynomial used in the Json format data files.
• When the value of the user preference AtlasRepDataDirectory is an empty string then data files that are fetched from remote servers are read into the GAP session without storing the files. (An advantage is that one need not care about where one has permissions for storing files. A disadvantage is of course that one has to fetch a file again whenever it is needed.)

Changes in version 2.1.2:

• The testfile mentioned in PackageInfo.g exits GAP in the end
• The external links in the package documentation were corrected (the links in version 2.1.1 pointed to a wrong directory)
