What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **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
- **fixed** — The description of what defines a cluster subgraph in the `gc` man page has been updated
- **fixed** — When rendering multiple files at once, page numbering state from previous jobs no longer leaks into the current job
- **fixed** — Logic to determine whether a rendered page is non-first has been corrected
- **fixed** — gvpr modulo expressions with an out-of-range modulo operand are now detected and result in an error message
- **fixed** — When gvpr dumps switch statements as text, they are now printed as switch statements instead of an if-else ladder
- **fixed** — An out-of-bounds read access during gvpr type checking has been fixed
- **fixed** — A null pointer dereference when freeing xdot objects has been fixed

###### 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.
