The PostGIS development team has, after a long period of meditation<br>
and soul searching, released version 1.4.0 of the spatial data<br>
extension for PostgreSQL.<br>
<br>
<a href="http://postgis.refractions.net/download/postgis-1.4.0.tar.gz" target="_blank">http://postgis.refractions.net/download/postgis-1.4.0.tar.gz</a><br>
<br>
This new version of PostGIS includes substantial performance<br>
enhancements, more detailed reference documentation, new output<br>
formats (GeoJSON) and an improved internal testing system. PostGIS 1.4<br>
also supports the recent PostgreSQL 8.4 release.<br>
<br>
Thanks to everyone who helped by testing during the release candidate process!<br>
