I don't know whether we plan to do another release from the GDB 10 branch. Maybe Joel could say. Also, is there a way to test that this works correctly? I'd imagine there just has to be a flag day sometime and then we find out? Or has someone built Rust and tried it with GDB trunk? Anyway, it's fine by me to do this. If there's no objections I can do it sometime. You may want to ping after a week or so in case I forget. thanks, Tom
