New features and bug fixes in Ferret and PyFerret v7.4.3 and 7.4.4

December 7, 2018

Ferret/PyFerret  version 7.4.4 is the same as v7.4.3, but is linked withNetCDF-4.4.1.1 instead of NetCDF-4.6.x .  Access to some OPeNDAP url's containing large datasets failed when using netCDF 4.6.

 

September 16, 2018

This is primarily a bug-fix release.  Here are the important changes:

  1. Two bugs are fixed having to do with coordinates and attributes for coordinates in netCDF files. 

    - A file with coordinates that have the attribute point_spacing="even", and also has coordinate bounds, but where the coordinates are not evenly spaced, was not initialized correctly.  This is fixed.

    - A file with irregularly-spaced longitudes coordinates having bounds that don't span the entire 360 degree range ran into a crash if strides are requested. This is fixed.
     

  2. The scripts "fland.jnl" and "focean.jnl" are updated so that the option to draw a transparent land or ocean mask is available in both Ferret and PyFerret, using the transparency features of PyFerret.
     
  3. CSV or TSV listings of more than 48 variables to a single file gave garbled results. This is fixed; it was due to loading a large list of variables into memory at once.  There is now no practical limit on the number of variables.
