Suggestion: Bump only at the major stable releases (e.g. from v3 to v4).

Currently in Fedora/EPEL we are supporting parallel installation of
of ZeroMQ v2 (2.2.0) and ZeroMQ v3 (3.2.4) libraries; and
we are also interested in supporting the parallel installation
of the ZeroMQ v4 libraries.

Current package contents in Fedora:
# rpm -ql zeromq

# rpm -ql zeromq3

  * you can't parallel install the zeromq[n]-devel packages
    (will cause file conflicts; e.g. libzmq.so)
