We're scheduled to present our final review to NASA for the project in

The software has been available in alpha release form for a while, and
we continue to update that frequently, but the alpha release needs
more testing and release engineering before a beta release will be
ready.  The beta release will also get rid of artifacts in the alpha
release format that are just placeholders for new HDF5 enhancements,
such as dimension scales.  The HDF5 enhancements we depend on are
available in an HDF5 development snapshot but not yet in a general
HDF5 release.

So if you choose to try testing with the alpha release, you should be
warned that the beta and subsequent releases will not support reading
files created by the alpha release that contain these development

The development and release schedules are available from:


and you will note from those plans that we're close to being on
schedule, but the beta release has been delayed due to a few
unanticipated problems, dependencies with the next HDF5 release, and
the need for work on ncdump and ncgen utilities that wasn't included
in the original proposal.  We'll update the online schedule soon.
