Improvements:

First release with wheels for Python 3.11 (thanks cibuildwheel!).

linux aarch64 wheels now bundle the same libzmq (4.3.4) as all other builds, thanks to switching to native arm builds on CircleCI.

Fixes:

Some type annotation fixes in devices.

Improvements:

Use zmq.Event enums in parse_monitor_message for nicer reprs

Fixes:

Fix building bundled libzmq with ZMQ_DRAFT_API=1

Fix subclassing zmq.Context with additional arguments in the constructor. Subclasses may now have full control over the signature, rather than purely adding keyword-only arguments

Typos and other small fixes

Fixing some regressions in 23.0:

Fix global name of zmq.EVENT_HANDSHAKE_* constants

Fix constants missing when using import zmq.green as zmq

Compatibility fixes:

zmq.utils.monitor.recv_monitor_message() now supports async Sockets.

Fix build with mingw

Changes:

all zmq constants are now available as Python enums (e.g. zmq.SocketType.PULL , zmq.SocketOption.IDENTITY ), generated statically from zmq.h instead of at compile-time. This means that checks for the presence of a constant ( hasattr(zmq, 'RADIO') ) is not a valid check for the presence of a feature. This practice has never been robust, but it may have worked sometimes. Use direct checks via e.g. zmq.has() or zmq.zmq_version_info() .

A bit more type coverage of Context.term and Context.socket

Compatibility fixes:

Remove all use of deprecated stdlib distutils

Update to Cython 0.29.30 (required for Python 3.11 compatibility)

Compatibility with Python 3.11.0b1

Maintenance changes:

Switch to myst for docs

Deprecate zmq.utils.strtypes , now unused

Updates to autoformatting, linting

New wheels for PyPy 3.9

Manylinux wheels for CPython 3.10 are based on manylinux2014

Fixes:

Fix strlcpy compilation issues on alpine, freebsd. Adds new build-time dependency on packaging .

In event-loop integration: warn instead of raise when triggering callback on a socket whose context has been closed.

Bundled libzmq in wheels backport a patch to avoid crashes due to inappropriate closing of libsodium’s random generator when using CurveZMQ.

Changes:

New ResourceWarnings when contexts and sockets are closed by garbage collection, which can be a source of hangs and leaks (matches open files)

Fix bundling of wepoll on Windows.

New features:

IPC support on Windows: where available (64bit Windows wheels and bundled libzmq when compiling from source, via wepoll), IPC should work on appropriate Windows versions.

Nicer reprs of contexts and sockets

Memory allocated by recv(copy=False) is no longer read-only

asyncio: Always reference current loop instead of attaching to the current loop at instantiation time. This fixes e.g. contexts and/or sockets instantiated prior to a call to asyncio.run .

ssh: $PYZMQ_PARAMIKO_HOST_KEY_POLICY can be used to set the missing host key policy, e.g. AutoAdd .

Fixes:

Fix memory corruption in gevent integration

Fix memoryview(zmq.Frame) with cffi backend

Fix threadsafety issue when closing sockets

Changes:

pypy Windows wheels are 64b-only, following an update in cibuildwheel 2.0

deprecate zmq.utils.jsonapi and remove support for non-stdlib json implementations in send/recv_json . Custom serialization methods should be used instead.

New features:

asyncio: experimental support for Proactor eventloop if tornado 6.1 is available by running a selector in a background thread.

Fixes:

Windows: fix type of socket.FD option in win-amd64

asyncio: Cancel timers when using HWM with async Sockets

Other changes:

Windows: update bundled libzmq dll URLs for Windows. Windows wheels no longer include concrt140.dll.

adopt pre-commit for formatting, linting

Fix fork-safety bug in garbage collection thread (regression in 20.0) when using subprocesses.

Start uploading universal wheels for ARM Macs.

Add workaround for bug in DLL loading for Windows wheels with conda Python >= 3.8

Fix type of Frame.bytes for non-copying recvs with CFFI backend (regression in 21.0)

Add manylinux wheels for pypy

This is a major release due to changes in wheels and building on Windows. Code changes from 21.0 are minimal.

Some typing fixes

Bump bundled libzmq to 4.3.4

Strip unused symbols in manylinux wheels, resulting in dramatically smaller binaries. This matches behavior in v20 and earlier.

Windows CPython wheels bundle public libzmq binary builds, instead of building libzmq as a Python Extension. This means they include libsodium for the first time.

Our own implementation of bundling libzmq into pyzmq on Windows is removed, instead relying on delvewheel (or installations putting dlls on %PATH%) to bundle dependency dlls.

The (new in 21.0) Windows wheels for PyPy likely require the Windows vcredist package. This may have always been the case, but the delvewheel approach doesn’t seem to work.

Windows + PyPy is now the only remaining case where a wheel has libzmq built as an Extension. All other builds ship libzmq built using its own tooling, which should result in better, more stable builds.

Fix wheels on macOS older than 10.15 (sets MACOSX_DEPLOYMENT_TARGET to 10.9, matching wheel ABI tag).

pyzmq-21.0.1 only changes CI configuration for Windows wheels (built with VS2017 instead of VS2019), fixing compatibility with some older Windows on all Pythons and removing requirement of VC++ redistributable package on latest Windows and Python < 3.8.

There still appears to be a compatibility issue with Windows 7 that will be fixed ASAP. Until then, you can pin pip install pyzmq<21 .

There are no changes from 21.0.0 for other platforms.
