The PostGIS development team has, after a long period of meditation
and soul searching, released version 1.4.0 of the spatial data
extension for PostgreSQL.

  http://postgis.refractions.net/download/postgis-1.4.0.tar.gz

This new version of PostGIS includes substantial performance
enhancements, more detailed reference documentation, new output
formats (GeoJSON) and an improved internal testing system. PostGIS 1.4
also supports the recent PostgreSQL 8.4 release.

Thanks to everyone who helped by testing during the release candidate process!
