# Meshes.jl v0.45

### New transforms:

- `Proj` for changing the CRS of geometries, domains and geotables

- `Shadow` for computing the “shadow” of a 3D domain onto XY, XZ or YZ

- `LenghtUnit` for changing the lenght unit of geometries and domains

### New discretization/tesselation:

- `DelaunayTriangulation` of geometries

- `DelaunayTesselation` of point sets

- `VoronoiTesselation` of point sets

### Breaking changes

(Multi-)polygons with more than 5000 vertices are now discretized with `DelaunayTriangulation` by default. `DehnTriangulation` is preferred for smaller polygons because it is faster.

- `FIST` renamed to `HeldTriangulation`
- `Dehn1899` renamed to `DehnTriangulation`
