February 4, 2010

The PostGIS development team has, after a long course of reflection
and a detailed self-examination of our various personal failings,
decided to release PostGIS 1.5.0 to the public.

 http://postgis.org/download/postgis-1.5.0.tar.gz

This new version of PostGIS includes a new "geography" type for
managing geodetic (lat/lon) data, performance-enhanced distance
calculations, GML and KML format readers, an improved shape loading
GUI, and other new features as well.

Especial thanks to:

* Dave Skea for algorithms and mathematics necessary to support
spherical geometry
* Nicklas Avén for the new performance enhanced distance calculations
and other distance-related functions
* Sandro Santilli for new buffering features (end caps and style options)
* Olivier Courtin for GML/KML input functions
* Guillaume Lelarge for support for the upcoming PgSQL 9.0
* George Silva for an example implementation of history tables
* Vincent Picavet for Hausdorff distance calculations
* The maintainers of GEOS, Proj4, and LibXML, without whom we would
have less of a spatial database

Love, the PostGIS project steering committee,

Mark Cave-Ayland
