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

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:

We appreciate all possible testing and feed-back you can provide to
make the upcoming 1.4 release a high quality affair. The sooner we get
feedback, the sooner we can release 1.4.0!
