Hi -

Reading Pieter's above listed blog post, he noted:

> we introduced the rule that new stable releases of the software must (a)
talk to old stable releases and (b) they must support existing apps,
without changes. We more or less succeeded with that, so ZeroMQ versions
3.2 and 4.0 work nicely with 2.2 and 2.1, for example.

I am interested to learn what this means.

Does the above example mean that a 3.2 PUB could talk to a 2.2 SUB, for
example?

Thank you,
Kevin
