Just in time for the holiday season the GeoServer team is happy to announce the coming of a new SLD editor extension based on the newly founded GeoExt project. Download the new extension and try it out. It also requires the installation of the rest plugin. A quick walk through of the installation and functionality can be found here.

The GeoExt library is a javascript framework for building rich web based mapping applications which is built on top of the the OpenLayers and Ext libraries. The project has recently kicked itself off with the forming of a mailing list, and a call for participation.
