My Xiphos Disk 1 is different to SPS #1062
 

Seems my Disk 1 of Xiphos is different to Disk 1 from SPS #1062, file dates are newer (SPS #1062 = 12 Oct 90, My Disk 1 = 23 Oct 90) and seems to affect the French language file:

SPS #1062 Disk 1: French/a 7036 12 Oct 90
My Disk 1: French/a 6955 23 Oct 90

My Disk 2 is the same as Disk 2 from SPS #1062, same 23 Oct 90 file dates!

Was this a bug fix release?

It also has Speedlock on track 56.0 of both disks, rather than the usual tracks to find protection either on track 0.1 or 79.0/79.1!
