At least the following options should be different per server:
@table @code
@item port=#
@item socket=path
@item pid-file=path
@end table
The following options should be different, if they are used:
@table @code
@item log=path
@item log-bin=path
@item log-update=path
@item log-isam=path
@item bdb-logdir=path
@end table
If you want more performance, you can also specify the following differently:
@table @code
@item tmpdir=path
@item bdb-tmpdir=path
@end table
@xref{Command-line options}.
If you are installing binary @strong{MySQL} versions (.tar files) and
start them with @code{./bin/safe_mysqld} then in most cases the only
option you need to add/change is the @code{socket} and @code{port}
argument to @code{safe_mysqld}.

@item @code{AUTO_INCREMENT} will not work with negative numbers. The reason
for this is that negative numbers caused problems when wrapping from -1 to 0.
@code{AUTO_INCREMENT} is now for MyISAM tables handled at a lower level and

bug fixes and minor enhancements to existing features will be
added to 3.23.
The replication code and BerkeleyDB code is still not as tested and as
the rest of the code, so we will probably need to do a couple of future
releases of 3.23 with small fixes for this part of the code. As long as
you don't use these features, you should be quite safe with
@strong{MySQL} 3.23!
Note that the above doesn't mean that replication or Berkeley DB doesn't
work; We have done a lot of testing of all code, including replication
and BDB without finding any problems. It only means that not as many
users uses this code as the rest of the code and because of this we are
not yet 100 % confident in this code.
