Hi, I'd like to make sure I understand. Is it the case that ideally, if we
could go back in time, we'd like to change the client so it defaults to
1.1? But since we can't, the next client that we ship/release will have the
most reasonable oldest version? If so, then since the most recent client
shipped is at 1.6, then I think we should put it back to 1.6 even though it
is 1.9 on master. Regardless of whether there are no backwards incompatible
changes between 1.6 & 1.9 -- because we need to stick to some
way-of-doing-things, and if we use 1.9, I suspect it will be confusing. At
least 1.6 was what we had at the end of kilo.

What we're saying is that for M*, N*, O*, ..., the version used in the
client will be the higher of server's MIN_VER_STR or 1.6, right?

Hey Lucas, Maybe I missed something about the client. If no version is
specified to the (next-released) client, won't it use 1.6? How are we going
to move it back to 1.1?
