The fourth (and still hopefully final) release candidate is now available, with bug fixes from RC3. Issues with segfaults in some functions and architectures have hopefully been resolved. Please download it and try it out!
The third (and hopefully final) release candidate is now available, with bug fixes from RC2. Issues with Mapserver and other third-party software connectivity have hopefully been resolved. Please download it and try it out!
The second release candidate is now available, with bug fixes from RC1. Please download it and try it out!
The first release candidate of new PostGIS 1.0 series is now ready for general download and testing. The 1.0 series is actually a departure from the previous 0.X series, in that the underlying disk representation of geometries is completely new. The new "lightweight" geometries are much smaller (particularly for 2D features, points, and short lines) and the indexes are also much smaller. The result is fewer disk accesses needed, better use of memory cache, and a faster system overall, particularly for large databases.
PostGIS 0.9.1 is a minor maintainance release, including the following new features:
The release also includes numerous small bug fixes.
PostGIS 0.9.0 is an important maintainance release, including the following new features:
The release also includes numerous small bug fixes.
PostGIS 0.8.2 is an important maintainance release, including the following new features:
The release also includes numerous small bug fixes, for different platforms and high load use cases.
PostGIS 0.8.1 is a bug fix release with some fixes to memory handling and the interface with GEOS.
We are very happy to announce the release of PostGIS 0.8.0, the first version of PostGIS that supports every function in the OpenGIS "Simple Features for SQL" specification document. The PostGIS 0.8.0 source code includes the OpenGIS SFSQL conformance test suite, so give it a try and see how we do!
Version 0.8 includes such useful SFSQL functions as Within(), Disjoint(), Touches(), GeomUnion(), Intersection(), Buffer(), and many many more! We also include some spatial aggregate functions, GeomUnion() and Collect(), that can roll up spatial result sets into resultants based on attribute grouping.
The first release of GEOS (geometry engine, open source) has been released at https://libgeos.org/. Using the GEOS library, it is possible for PostGIS to perform all the operations in the OpenGIS Simple Features for SQL Specification.
That means that operations like Touches(), Contains(), Intersection(), Buffer(), Centroid(), Union() can all be supported. To try out PostGIS-with-GEOS, download the CVS snapshot of PostGIS and follow the directions in the README file carefully.
