From 32 bits to 64 bits

From 32 bits to 64 bits.

All MultiPress applications will now need a 64 bit OS. Apple has long ago announced that they will stop supporting 32 bits and have recently also confirmed this. Apple announces macOS Catalina. The big difference is that macOS 10.15 Catalina no longer supports 32-bit apps. This means that all MultiPress versions below 5.1.00r1, for which no 64-bit updates are available, will no longer work. In Mojave that was still the case. During the installation of Catalina a message will appear about which apps are still 32-bit and will no longer work. So first request your upgrade to MultiPress version 5.1 before upgrading your Mac. For Windows devices, the same system requirement applies.
