This release is unsupported. It is only used as an intermediate version in the 0.2-to-0.5 upgrade path. Read the 0.5 release notes for more information.
At the time of this writing (2014-07-06), openmeteo.org and hydroscope.gr run this branch. The master branch has large and important changes but it is still in heavy development.
Very old and mostly unsupported. Avoid using it unless you are somehow stuck with one of the applications that have been removed (hrain, contourplot, gis_objects).
