[Bruce Dubbs]

New point version.

[Joe Locash]

## [14.1.5] – 2026-04-12

### 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.
