  • Updated the java library to support remote file transfers on secure ssh servers. Apache Mina SSHD SSHD Overview — Apache MINA

The following issues were fixed:

  • The error associated with layer_sum/layer_mean tile plots for unconventional 3D variables (#352)
  • Incorrect maximum value in tile plot legend when load a configuration file with a logarithmic scale (#353)
  • Unable to choose layer ranges with two or more datasets in the Dataset Panel (#356)

Known Issues

  • Tile plots created from datasets that use a Polar Sterographic Projection may be unable to display the satellite image layer due to transforming issues.

2.1.6 (previous release)

The following new features were added:

  • Visualize differences between time-independent model files #341
  • Reading netCDF files with unconventional dimension names #344
  • Calculate layer (sum and mean) statistics for all layers or a subset of layers chosen in the dataset panel followed by creation of a new tile plot. #345

The following issues were fixed:

  • Incorrect values for probed grid cells for statistics “maximum 8hr mean” in tile plot #325
  • Batch script does not turn off column/row labels and legends as specified in the configuration file #347
