[OSGeo-Discuss] PostGIS 1.4.0 Beta 1

[Paul Ramsey]

The PostGIS team is super happy to announce that a beta release of
PostGIS 1.4.0 is now available for download and testing!

  http://postgis.refractions.net/download/postgis-1.4.0b1.tar.gz

The 1.4 series includes a large number of new features, fixes,
speed-ups and mini chocolate chip cookies.

PostGIS 1.4 is best consumed along side helpings of the latest Proj4
and GEOS libraries:
