[geos-devel] GEOS 2.2

GEOS 2.2 is on the street, from the change log:

Changes in 2.2.0

- Performance improvement in OverlayOp::insertUniqueEdge()
- CoordinateSequence copy removal in EdgeRing
- Minor memory allocation improvements
- Higher dimensions interface for CoordinateSequence
- Added getCoordinatesRO for Point class
- NEW WKB IO
- NEW Simplified and stabler C API

I believe 2.2 includes a change in the binary interface, which means  
you will have to recompile PostGIS and other dependent client  
programs, but not in the source interface, so the old programs should  
still compile sucessfully against it.  Strk can correct me if I am  
wrong.

The performance improvements can be quite large for some use cases.
