Mailman 3.1 is "close" to release (how close is for Barry, Florian and
Aurelian to say, but the improvements over 3.0 in the dev branches are
substantial).  I strongly (as co-mentor :-) recommend using the dev
branches.

I'm not sure how far bundler has been updated, but the kind of issue
you are likely to run into is, for example,
       <https://gitlab.com/mailman/mailman-hyperkitty/issues/10>
This is a problem with the environment that tox sets up for standalone
testing, not with interoperability of current Mailman components with
each other.  However, as stated in
            <https://gitlab.com/mailman/mailman/issues/181>
this kind of thing is generally not going to get timely fixes in static
bundles.

Aside to devs: I think we should toxify the procedure at
<https://wiki.list.org/DEV/SetupDevEnvironment>, and allow
specification of a ref tuple for the mailman components.
