Right now the latest source code is r999, so in my own concern, i think the next release will be FPS 1.5 to the public.
But there's still some important changes you need to do after the release. Here are some:
OrderView Layout needs to be STATE, not STATELESS.
We have to customize the layout every time we restart the system.
Server/Waitress Name on Kitchen Display Tickets.
It'll be confusing when the Bartender have a couple of tickets to serve, being able to see the name would be helpful.
