NetCDF 3.5.0 Release Notes
The source distribution for netCDF 3.5.0 is now available in ZIP or compressed tar
form. Instructions for installation are available in the INSTALL.html file that
accompanies the software or online.
Release 3.5.0 is mostly bug fixes and portability enhancements to version 3.4,
but also includes Robert Pincus's Fortran90 interface. The netCDF file format
is still unchanged, so files written with previous versions can be read or written
with version 3.5.0.
There is a change in behavior: In netCDF 3.4, calling nc_close() or nc_endef()
would remove any extra space in the header, causing all the data values to be
moved up (towards the beginning of the file) if the space needed for the file
header had decreased due to deleting an attribute or decreasing the number of
attribute values. This was not the intended behavior and could be very costly
for large datasets. In this version, extra space in the header persists and
the size of the header will never shrink as the result of netCDF function calls.
Hence space "reserved" by calling the nc__endef() function (or its
equivalent in other language interfaces) will be preserved for later efficient
additions of new attributes or non-record variables.
