Using both versions, I simply wish to inform users that a library saved under 5.60 would NOT be usable in 5.15. The rslib can be loaded but stay invisible in 5.15, which can be very frustrating.
Similarly, a station saved in RS5.60 won’t open up back in 5.15, which is something to consider before using the 5.60.
Maybe one day a 5.15 compatibility saving mode ? A least needed for the librairies ?
