The bug difference for users is that this version is compiled with postgresql support, but I didn't test it as I have no test postgresql database available nor ever worked with it.
It is necessary to completely remove older PSPP version from your MSWindows computer before installing this version.
I would love to see your reports.
Ps: If anybody can test it with a postgresql server, I would love to hear what happens when
libecpg.dll
libecpg_compat.dll
libpgtypes.dll
is removed from \Program Files\PSPP\bin Is the postgresql support still working?
Have fun
