Great news!
A (very) small first observation: The acf_version.txt says 2.0.3 (as to be expected), but the .acf files (xsMU2B60_4B_GLASS.acf etc.) all still contain "P acf/_version 2.0.2". Which obviously means they are displayed in XP with "2.0.2" on their tile for the A/C selection. Just did confuse me a bit at first
