 - **Breaking**: Using Graphviz as a library on Windows now requires the `GVDLL`
   symbol to be set to ensure correct linking.
+- **Breaking**: Graphviz headers no longer define the `boolean` type. A

   be a pointer to a function returning a C99 `bool` instead of a
   Graphviz-specific `boolean`.
