CZMQ version 4.0.0 stable, released on 2016/11/04

  • v4.0.0 breaks API and ABI compatibility with v3.0.2.
    The ABI version has been bumped to 4.

  • The v2 API, which have been declared DEPRECATED in v3.0.0
    released on 2014/10/15, have now been declared RETIRED
    and removed from this release. The following classes are gone:

    • zauth_v2, use zauth
    • zbeacon_v2, use zbeacon
    • zctx, use zsock
    • zmonitor_v2, use zmonitor
    • zmutex
    • zproxy_v2, use zproxy
    • zsocket, use zsock
    • zsockopt, use zsock
    • zthread, use zactor

    The following DEPRECATED methods have also been declared
    RETIRED and removed from their STABLE classes:

    • zcert_fprint, use zcert_print
    • zcertstore_fprint, use zcertstore_print
    • zhash_foreach (and callback), use zhash_first/next
    • zhashx_foreach (and callback), use zhashx_first/next
    • zhashx_autofree, use zhashx_set_destructor
    • zloop_ignore_interrupts, use zloop_set_nonstop
    • zpoller_ignore_interrupts, use zpoller_set_nonstop

  • Some STABLE APIs unfortunately had to be slightly changed to
    fix critical issues. From v4.0.0 we commit to avoid incompatible changes
    to STABLE APIs.
    The following signatures have changed:

    • v3.0.2: byte * zarmour_decode (zarmour_t *self, const char *data, size_t *decode_size)

      zsys_auto_use_fd (see doc/zsys.txt for details)

  • New DRAFT APIs early-release mechanism. New APIs will be introduced early
    in public releases, and until they are stabilized and guaranteed not to
    change anymore they will be unavailable unless the new build flag
    --enable-drafts is used. This will allow developers and early adopters to
    test new APIs before they are finalized.
    NOTE: as the name implies, NO GUARANTEE is made on the stability of these APIs.
    They might change or disappear entirely. Distributions are recommended NOT to
    build with them.

    The following DRAFT classes were added:

    • zproc
    • ztimerset
    • ztrie

    The following DRAFT methods were added to their respective STABLE class:

    • zcert_unset_meta
    • zcertstore_set_loader, zcertstore_empty
    • zframe_routing_id, zframe_set_routing_id, zframe_group, zframe_set_group
    • zhashx_unpack_own, zhashx_pack_own, zhashx_serializer_fn, zhashx_deserializer_fn
    • zmsg_routing_id, zmsg_set_routing_id
    • zstr_str

  • Support for new libzmq DRAFT socket types was added to zsock. See libzmq 4.2.0
    release notes and doc/zsock.txt for more details. NOTE: until libzmq declares
    these as STABLE, the CZMQ support will be in DRAFT state as well.

  • Support for all new libzmq socket and context options was added to zsock. See
    libzmq 4.2.0 release notes and doc/zsock.txt for more details.

  • Many, many bug fixes. Check git log for the complete set of changes.
