Hi Sebastian,

matrices seem to work fine here (using beta tagged as 2016.04.01 13:01
[see my previous message to the list]).

If you allow me some suggestions, I think it may be worth considering
the following when dealing with betas:

1. Always give the beta version, otherwise it may be impossible in some
cases to know whether something behaves as expected or not.

2. Always backup your previous beta before upgrading it. New betas can
contain bugs or unexpected features and you may want to stick to your
old beta while things are fixed.

Just in case it helps,
