-% SW_NEW    What's new in this version of seawater.
-%
-% 22 April 1998  release 2.0.1 (For version 5.x of Matlab)
-% ********************************************************
-% This version is not optimised but will run under Matlab 5.x
-% sw_satAr    New routine. Solubility of Ar in seawater
-% sw_satN2    New routine. Solubility of Ar in seawater
-% sw_satO2    New routine. Solubility of Ar in seawater
-% sw_test     Updated to include tests for above
-% 
-% April 1998  release 1.2e (For version 4.x of Matlab)
-% ************************
-% sw_alpha    Fixed bug where temp used in calculations regardless of
-%             whether 'temp' or 'pmpt' was passed as keyword.
-%
-% sw_info     Shorter version. Refer users to web pages
-%             http://www.marine.csiro.au
-%
-% sw_ver      New routine. Returns version number of SEAWATER
-%
-% sw_test     New Routine. Run a test on the SEAWATER routines
-%             and compare results with literature values
-%
-% 94/11/15 release 1.2d
-% **********************
-% sw_bfrq.m   Now also returns potential vorticity.
-%             Thanks to Greg Johnson (gjohnson@pmel.noaa.gov)
-%
-% sw_gvel.m   OMEGA=7.29e-5 changed to OMEGA=7.292e-5 to be
-%             consistent with sw_f.m
-%
-%             IMPORTANT CHANGE: The usage of the following 
-%             routines has changed!
-%
-% sw_alpha.m |    All these routines expect (S,T,P) to
-% sw_beta.m  |--  be passed instead of (S,PTMP,P) as in 
-% sw_aonb.m  |    previous releases of seawater.
-%                 Fast execution can still be obtained by passing
-%                 ptmp with a string flag 'ptmp' see help.
-%
-% 94/10/19 release 1.2c
-% **********************
-% Added routine sw_new.m to inform of updates and new features.
-% sw_bfrq.m   Fixed bug where LAT = [] was needed as argument when
-%             no latitude values are being passed.
-%             Now pass PRESSURE instead of DEPTH -> more consistent
-%             though only a negligible change is answers.
-%
-% sw_info.m   Updated to include a registration section.
-%             Noted that software is FREE.  
-%             Noted best email address is seawater@ml.csiro.au
