wouldn't run in 2007a. Maybe 2007b is different.
Well, aside from various java related issues, and problems with OpenGL
graphics, the one example which springs to my mind is when using xlsread
under Windows. On 6.5 it used the built in biffread code, but from R14
onwards it chooses to use the COM server if a copy of Excel can be found on
the machine. The big difference I notice with this is that dates are now
treated as strings, not as numbers.
Apart from that, the only time I require different code for later versions
is when saving, in which case I might require the -v6 option to not
compress data on the way to the disk.
