CDF V3.8.1 is released.
This version has various improvements and bug fixes: including adding
support for Unicode in UTF-8 encoding, handling reverse leap seconds
(from second 58 to second 0) in the CDF_TIME_TT2000 time routines,
adding CDF-JSON conversion and enhanced CDF-netCDF conversion, support for ARM
and Apple M1 processors, and adding a suite of easy-to-use functions:
readCDF and readVariable, for Java/Perl/C#/IDL
to read the CDF/variable in a single call with the retrieved information in
the key/value pair form.
Refer to the respective document in cdf_docs
for its interface or information.
C, FORTRAN, C#, Java and Perl interfaces, MATLAB and IDL plugins
have been updated. For further details and changes, see
