The PostGIS development team is super excited, can hardly believe that they are actually doing this, aren't maybe even sure that they are ready to make this kind of commitment, not so young, and not when we have so much more living to do, but:
PostGIS 2.0.0 is complete and available for download.
The development process for 2.0 has been very long, but has resulted in a release with a number of exciting new features.
Raster data and raster/vector analysis in the database
Topological models to handle objects with shared boundaries
PostgreSQL typmod integration, for an automagical geometry_columns table
3D and 4D indexing
Index-based high performance nearest-neighbour searching
Many more vector functions including
ST_Split
ST_Node
ST_MakeValid
ST_OffsetCurve
ST_ConcaveHull
ST_AsX3D
ST_GeomFromGeoJSON
ST_3DDistance
Integration with the PostgreSQL 9.1 extension system
Improved commandline shapefile loader/dumper
Multi-file import support in the shapefile GUI
Multi-table export support in the shapefile GUI
A geo-coder optimized for free US Census TIGER (2010) data
We are greatly indebted to our large community of beta testers who valiantly tested PostGIS 2.0.0 and reported bugs so we could squash them before release time.
And also we want to thank our parents for making PostGIS possible.
Yours,
The PostGIS development team
