v1.5.0 - 2025-09-13

Added

Added support for the rcvtimeo property, now recv(::Socket) and the other receive methods will throw a TimeoutError if the receive times out (#217).

v1.4.1 - 2025-06-13

Changed

Implemented Base.show() methods for Socket and Context for pretty-printing (#255).

Fixed

The precompilation workload now hardcodes the use of IP address 127.0.0.1 instead of resolving localhost, which fixes precompilation on machines that may have localhost resolve to a different node (#257).

v1.4.0 - 2024-11-30

Added

Implemented send_multipart() and recv_multipart() for working with multipart messages (#253).

v1.3.0 - 2024-08-03

Added

Support for creating Message's from the new Memory type in Julia 1.11 (#244).
Full Bindings to libzmq (#232).

Deprecated

The Base.convert(IOStream, ::Message) method has been deprecated due to buggy behaviour, use IOBuffer(msg) instead (#247).

Fixed

Fixed isfreed(), which would previously return the wrong values (#245).

v1.2.6 - 2024-06-13

Added

lib_version() to get the libzmq version (#240).

Fixed

Fixed a precompilation bug that would cause creating a sysimage with PackageCompiler.jl on Julia 1.6 to fail (#242).

v1.2.5 - 2024-05-28

Fixed

Fixed support for Julia 1.3 in the precompilation workload (#237).

v1.2.4 - 2024-05-27

Changed

Refactored the internals to use the public FileWatching.FDWatcher instead of FileWatching._FDWatcher (#215).

Fixed

Docstrings to inner constructors are now assigned properly (#227).
Socket now holds a reference to its Context to prevent it from being garbage collected accidentally (#229).
Changed the precompilation workload to use any available port to avoid port conflicts (#234).

v1.2.3 - 2024-05-12

Added

Support for setting ZMQ_IMMEDIATE and ZMQ_CONFLATE on sockets (#209, #222).
