I'd like to announce the immediate availability of
org.zeromq/jeromq-0.4.2 on Maven central. The single biggest change is
now JeroMQ now has full native java security support! Special thanks
to Frédéric Déléchamp for updating the codebase to v4.1.7.

There wasn't an announcement for v0.4.1 because it was quickly
realized that adding security via kalium (libsodium) broke JeroMQ on

0.4.2 includes the following changes:

#443: Fix issue where JeroMQ was broken on Android. Security no longer
depends on libsodium and is now pure Java

v0.4.1 (2017-06-28)


JeroMQ is now based of of 4.1.7 of libzmq which means it also now
support security


#413: fixed a NullPointerException when ZMQ.ZMQ_TCP_ACCEPT_FILTER is used
