IMPORTANT:
If you are installing this release in place of a previous recent release, the H2 EPSG cache must be cleared (just remove the directory, usually either at /tmp/.h2 or .ncWMS2/.h2), otherwise errors will occur.

Profile / timeseries plot improvments
Exposed dataset metadata from catalgoue
Staggered grid improvements
