CZMQ 4.2.0
CZMQ version 4.2.0 stable, released on 2019/02/10
-
Note for packagers: as pkg-config's Requires.private is now used to properly
propagate dependencies for static builds, the libczmq*-dev or czmq-devel or
equivalent package should now depend on the libfoo-dev or foo-devel packages
of all the libraries that czmq is linked against, or pkg-config --libs libczmq
will fail due to missing dependencies on end users machines. -
New STABLE APIs have been added to wrap new libzmq context
