GEOS 3.3.0 is out:
http://download.osgeo.org/geos/geos-3.3.0.tar.bz2

This release introduces a fair amount of new C-API interfaces
and a brand new PHP binding. Full details in the NEWS file:
http://trac.osgeo.org/geos/browser/tags/3.3.0/NEWS

As with any release since 3.0.0 there is complete binary
compatibility with clients linked against the C-API.
These include, but are not limited to, PostGIS.
For a list of known clients: http://trac.osgeo.org/geos/wiki/Applications
(add yours, if not already listed!)

GEOS is a C++ port of the JTS Topology Suite.
This release targets version 1.12 of the library, but doesn't reach full
feature parity yet. Missing JTS functionalities:

 From JTS-1.11

 - Densifier class
 - 'match' package, for geometric similarity detection
   (HausdorffSimilarityMeasure, AreaSimilarityMeasure)
 - MinimumDiameter.getMiminumRectangle()
 - Triangulation API
 - VoronoiDiagramBuilder
 - createSquircle and createSuperCircle in GeometricShapeFactory

 From JTS-1.12

 - MinimumClearance class
 - nearestNeighbours method to STRtree
 - RandomPointsBuilder / RandomPointsInGridBuilder
 - KochSnowflakeBuilder
 - SierpinksiCarpetBuilder

If you'd like to sponsor development of any of the above items (or others)
for next feature release of GEOS (3.4.0) please drop me a note.
