<br><br>February 4, 2010<br>
<br>
The PostGIS development team has, after a long course of reflection<br>
and a detailed self-examination of our various personal failings,<br>
decided to release PostGIS 1.5.0 to the public.<br>
<br>
<a href="http://postgis.org/download/postgis-1.5.0.tar.gz" target="_blank">http://postgis.org/download/postgis-1.5.0.tar.gz</a><br>
<br>
This new version of PostGIS includes a new "geography" type for<br>
managing geodetic (lat/lon) data, performance-enhanced distance<br>
calculations, GML and KML format readers, an improved shape loading<br>
GUI, and other new features as well.<br>
<br>
Especial thanks to:<br>
<br>
* Dave Skea for algorithms and mathematics necessary to support<br>
spherical geometry<br>
* Nicklas Avén for the new performance enhanced distance calculations<br>
and other distance-related functions<br>
* Sandro Santilli for new buffering features (end caps and style options)<br>
* Olivier Courtin for GML/KML input functions<br>
* Guillaume Lelarge for support for the upcoming PgSQL 9.0<br>
* George Silva for an example implementation of history tables<br>
* Vincent Picavet for Hausdorff distance calculations<br>
* The maintainers of GEOS, Proj4, and LibXML, without whom we would<br>
have less of a spatial database<br>
<br>
Love, the PostGIS project steering committee,<br>
