Fixed

• The JSON renderer of the core plugin now understands a cluster to be indicated by the common rules, including the “cluster” prefix being case insensitive and the cluster=true attribute as an alternative. #2187
• The description of what defines a cluster subgraph in the gc man page has been updated. #2187
• When rendering multiple files at once (e.g. dot -Tsvg -O file1.dot file2.dot), page numbering state from previous jobs no longer leaks into the current job. This was a regression in Graphviz 2.40.0. #2827
• Logic to determine whether a rendered page is non-first has been corrected.
• gvpr modulo expressions with an out-of-range modulo operand are now detected and result in an error message.
• When gvpr dumps switch statements as text, they are now printed as switch statements instead of an if-else ladder. This avoids incorrect interpretation of break statements in error messages. #2822
• An out-of-bounds read access during gvpr type checking has been fixed.
• A null pointer dereference when freeing xdot objects has been fixed.
