Yes you will be able to use an 8.3 launcher to launch against 8.1 gateways.

Not an issue necessarily since it's by design, but by default you won't be able to launch against gateways on 8.1.33 or older.

> Testing Ignition 8.3.0 Beta. I had to upgrade my Designer Launcher to 1.3.0 Beta-1 to access the 8.3 designer. However, I'm now unable to open any of my other 8.1.23 designers; I receive a "Launch client jar invalid" message. I ended up downgrading my designer, but this means I can no longer access 8.3. Has anyone else encountered this issue?
