@elramirez1976 Are you referring to the message that says that in the future, some applications may not be supported? The likelihood is that the next version of OS X after Mojave won't run any 32-bit apps at all. This includes TS3 but not TS4. There are still questions about whether updates to other features of the operating system would be incompatible with TS4, but those of us who don't work at Apple really have no idea.
Still, the best thing to do is to wait to update your OS until you're sure that all of your preferred apps will still run, or that you can install new versions. But you have almost a year before the next OS is released, so I wouldn't worry about it right now.
@puzzlezaddict thank you for the response! At least I can rest easy for a while!
