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'.

See the CHANGELOG .

- **added** — Graph attribute svgid sets the id property of the <svg> of a graph
- **fixed** — An sfdp crash has been fixed
- **fixed** — Graphs that induce invalid trapezoids during ortho routing no longer cause Graphviz crashes on non-Windows platforms
- **fixed** — edgepaint no longer crashes when passed the illegal option -s
- **fixed** — cluster no longer crashes when passed single character command-line options without arguments
- **fixed** — cluster of trivial graphs with no nodes no longer crashes
- **fixed** — cluster on large chains of nodes no longer references out-of-bounds memory

###### Added

- Graph attribute `svgid` sets the id property of the &lt;svg&gt; of a graph.
  \#2850

###### Fixed

- An `sfdp` crash has been fixed. This was a regression in Graphviz 15.1.1.
  \#2852
- Graphs that induce invalid trapezoids during ortho routing no longer cause
  Graphviz crashes on non-Windows platforms. These scenarios now exit with
  failure gracefully. #2784
- `edgepaint` no longer crashes when passed the illegal option `-s`. #2857
- `cluster` no longer crashes when passed single character command-line options
  without arguments (e.g. `cluster -C`). #2857
- `cluster` of trivial graphs with no nodes no longer crashes. #2857
- `cluster` on large chains of nodes no longer references out-of-bounds memory.
  This was a regression in Graphviz 7.1.0. #2857
