Enlightenment Research LLC is happy to announce the availability of PyQ 4.1.0, a minor release that includes the following new features as well as performance improvements.

New features:

  • Improved calling Python functions from q.

    • Objects of any type supported by the K() constructor can be returned to q.
    • Python functions can be called from multiple q threads.

  • Calls from Python to q will now release GIL allowing concurrent execution of q code from multiple threads.

  • Added a backtrace mode (requires kdb+ 3.5 or later) in which q stack trace is printed on q errors.

  • Experimental Windows support.

For an overview of changes see “What’s new in PyQ 4.1”.

To upgrade, run

$ pip install -i https://pyq.enlnt.com --no-binary pyq -U pyq

Enjoy!

Thanks to everyone who tested PyQ on Windows and provided feedback on Github.  Based on your feedback, we have issued a bug-fix release, PyQ 4.1.1.  See release note at 1.  This release is only of interest for those testing PyQ on Windows.  We still consider Windows support to be experimental and not ready for production use.

If you would like to install PyQ on your Windows host, please follow the installation instructions at 2.  Please report any issues on our Github page. 3
