Version 1.0  26th Sept 1994.
This was the first version put onto the anonymous ftp server 
medphys.ucl.ac.uk

Version 1.01 30th Sept 1994.
This corrected a number of problems with the original code, so that it now runs
properly on the acc (Sun ANSI C) and gcc (GNU C/C++) compilers. The original 
version only compiled properly only on g++ (GNU C++) and CC (Sun C++) 
compilers. Some of my code was obviosly C++, when I though it was ANSI C!

Version 1.02 14 Oct  1994
This release corrected a number of memory allocation errors in 'yagi', 'output'
and 'optimise'. Memory was not always freed in earlier releases. Also, a for
loop in all 3 programs had a calls to routines which allocated memory many 
times, when it was only needed once. The output file now has # to mark comments,
which the gnuplot (GNU plotting program) recognises.

Version 1.03
'optimise' was compleatly re-written, so that it no longer used lots of
tempory files on disk. This makes it much faster (6-7x on a 6ele beam ).

Version 1.04 First DOS based version.

Version 1.05 26 Oct 1994.

Optimise now takes lots of options. You dont need such a complex command to get it to work. There are sensible defaults. Some options dont work on optimise - '-g' , '-T' , -t' and '-p'.

Version 1.06 28/10/94

Released on to one user. Options 'T' and 't' now work. Genetic algorithm still does, although man page mention them.

Version 1.07 31/10/94

Added option '-w' that averages data of 3 frequencies to build wide-band antenna. A lot of integers for best/latest design were removed, puting them instead in a structure. 

Version 1.08 5/11/94.

Genetic algorithm works now. Parameters used internally (probability of crossover etc) may not be anywhere near optimum. GA does not seem to offer any real advantage, but early days yet.

Added a new program 'rantest' to check the randome number generators are working
okay.

Version 1.09

Added a facility in 'output' to print 3dB bandwidths. Removed printing of parameter 'F', as this is of little use and space is needed. 

Changed default elements altering form only parasitic to all elements.

Corrected an error in which the .gai file prints the E-plane data and H-plane data refersed.
