See the CHANGELOG .

- **added** — Add option neato -n3 for fit ends of edges to nodes' borders when edge trajectory is set
- **added** — Orthogonal edges now support rounded corners via the radius edge attribute, rendering corners as smooth arcs instead of sharp angles when splines=ortho is set and radius > 0
- **fixed** — Remove some Undefined Behavior in sparse matrix calculations
- **fixed** — In the Autotools build system, disable PHP bindings build when PHP interpreter is available but php-config is not

###### Added

- Added option `neato -n3` for fit ends of edges to nodes' borders when edge
  trajectory is set. #2736
- Orthogonal edges now support rounded corners via the `radius` edge attribute.
  When `splines=ortho` is set and an edge has `radius > 0`, corners are rendered
  as smooth arcs instead of sharp angles. The radius value controls the size of
  the corner arc. Default is 0 (square corners).

###### Fixed

- Some Undefined Behavior in sparse matrix calculations has been removed.
- In the Autotools build system, when the PHP interpreter (`php`) is available
  but `php-config` is not, building the PHP bindings is no longer enabled. This
  was a regression in Graphviz 2.42.0. #2788
