This document summarizes the state of GeoServer and outlines key developments over the past two years. It discusses improvements to rendering, projections, styling, raster support, web services (WMS, WCS, WPS), monitoring/auditing, and new data stores. Upcoming work includes WFS 2.0, enhanced security, scripting integration, and version control via GeoGit. GeoServer continues to expand capabilities for open source geospatial data sharing and analysis.
