Before running this new beta, I file-compared back to my current installation to look for what's changed:
1. D008.DAT file still needs updating to include military flags, etc. from my latest version. Same applies to the FLAGS folder.
2. The following files are newer in this new installation. I'm assuming this is another update to the navigation aids database.
D009.DAT - completely new file
L004.DAT
L006.DAT
L009.DAT
I'll now get on with testing this installation.
