0.11.0

This release corrects the historical misspelling of Delaunay throughout the C and JavaScript APIs. The misspelled names are removed rather than retained as aliases, so callers must update them when upgrading.

C API

Replace the public C names as follows:

0.10 name	0.11 name
`jcv_delauney_edge`	`jcv_delaunay_edge`
`jcv_delauney_iter`	`jcv_delaunay_iter`
`JCV_OPTION_DELAUNEY_ONLY`	`JCV_OPTION_DELAUNAY_ONLY`
`jcv_delauney_generate()`	`jcv_delaunay_generate()`
`jcv_delauney_get_edge_count()`	`jcv_delaunay_get_edge_count()`
`jcv_delauney_begin()`	`jcv_delaunay_begin()`
`jcv_delauney_next()`	`jcv_delaunay_next()`
`jcv_delauney_iter.delauney_only`	`jcv_delaunay_iter.delaunay_only`

Recompile every translation unit that includes jc_voronoi.h after making these changes.

JavaScript API

Replace the JavaScript and TypeScript members as follows:

0.10 name	0.11 name
`voronoi.delauneyEdges()`	`voronoi.delaunayEdges()`
`diagram.numDelauneyEdges`	`diagram.numDelaunayEdges`
`diagram.renderDelauney()`	`diagram.renderDelaunay()`

Serialized diagram objects now use delaunayEdges instead of delauneyEdges. The interactive demo query parameter is likewise renamed from delauney to delaunay.

0.10.0

This release introduces some breaking API changes.

Edge iteration

Edges are now returned by value through jcv_edge_iter. Replace linked-list iteration:

const jcv_edge* edge = jcv_diagram_get_edges(&diagram);
while (edge) {
    use(edge);
    edge = jcv_diagram_get_next_edge(edge);
}

with:

jcv_edge_iter iter;
jcv_edge edge;
jcv_diagram_get_edges(&diagram, &iter);
while (jcv_edge_next(&iter, &edge)) {
    use(&edge);
}

jcv_diagram_get_next_edge and jcv_edge.next were removed. The value written by jcv_edge_next is caller-owned; reusing the output variable overwrites it.

Site edges

jcv_graphedge and jcv_site.edges were removed. Use the same iterator API:

jcv_edge_iter iter;
jcv_edge edge;
jcv_site_get_edges(&diagram, site, &iter);
while (jcv_edge_next(&iter, &edge)) {
    use(&edge);
}

Site edges remain counter-clockwise. edge.sites[0] is the requested site and edge.sites[1] replaces jcv_graphedge.neighbor.

Custom clipper fill_fn implementations that accessed jcv_site.edges must be updated; use src/jc_voronoi_clip.h as the reference implementation.
