Version 3.02

Improved computation efficiency.

Minor bug fixes.

Version 3.01

Bug fix in gsw_SA_Sstar_from_SP (line 182).

Version 3.0

Major improvements

48-term density equation introduced (intended for use by observational,
theoretical oceanographers and ocean modellers). The use of a single
density equation will ensure a unified field.

the Absolute Salinity Anomaly takes into account evaporation and
dilution.

Version 2

Absolute Salinity Anomaly extended to cover all areas of the ocean
