Release Notes: This release fixes an important bug introduced in previous release that broke the ability to use Mapserver LINE layers with PostGIS.
Release Notes: This release added an ST_AsGeoJSON() function, PostgreSQL 8.4 support, performance improvements with GEOS 3.1, memory leak fixes, documentation improvements, and more reliable handling of curve types.
Release Notes: Improvements in the shp2pgsql/pgsql2shp utilities (better Windows support, DBF-only loading support, support for OS X 10.5, and output for Date types in DBF). A new function ST_SimplifyPreserveTopology(geometry, float8) to simplify polygons without creating invalid geometry. KML support updates and SVG support updates.
Release Notes: Improvements in the TIGER geocoder. A fix for an ST_EndPoint() crash bug. ST_AsGML() has been modified, improving v2 and adding v3 support. A fix to ensure ST_Envelope() returns valid geometries. The JDBC build has been changed to use Ant. A fix for better OS X support. A fix to the WKB parser to do simple validity checks.
Release Notes: A bug in Within() caused by a point-in-polygon performance shortcut was fixed. A bug in indexes with null on PostgreSQL 8.2 was fixed. JTS handling of multi-dimensional data was fixed. GCJ Java support was fixed. A fix was made for JDBC compatibility in PostgreSQL 8.2. The AsKML() function was added. Transform() performance was improved when no transform is actually required.
Release Notes: This release adds support for Curve type, serialization and de-serialization, index bindings, and documentation. There are performance enhancements for Contains and Within for point-in-polygon cases. There is support for basic SQL/MM functions to align with the ArcSDE SQL/MM implementation.
Release Notes: A C API change that broke 64-bit platforms was fixed. Z ordinate was added to reprojections. spatial_ref_sys.sql was updated to be synchronized with EPSG 6.11.1.
Release Notes: Support for the upcoming PostgreSQL 8.2 release was fixed. A bug in which the collect() function discarded the SRID of input was fixed. An SRID match check was added in MakeBox2d and MakeBox3d. The regression tests were fixed to pass with GEOS-3.0.0.
Release Notes: New affine transformation functions, bugfixes in grid snapping and vertex ordering functions, an improved JDBC library, and better 64-bit architecture support.
