The GeoServer project has announced the release of version 1.3.2. They write in, "Though an inconspicuous number, the latest release of GeoServer is one to get excited about. It includes a number of great features, including speed increases of up to 60-70% from GeoTools optimizations, pdf output, cache control of headers, and numerous bug fixes. GeoServer also received support from Google to improve GeoServer to be compatible with Google Earth, with great KML/KMZ output through WMS using the standard GeoServer SLD-based styling, an SLD creation wizard, and a KMScore optimization to return Ground Overlays when the number of Placemarks might slow Google Earth."
