Wait, what?

6-Apr-2026

As we've been winding down the commercialization effort, shutting down servers and archiving materials, I saw this week that the PySimpleGUI repositories are going to be of little use. Everything was switched over to using PySimpleGUI 5. The documentation is PySimpleGUI5 specific as well. So, I made a decision a couple of days ago to get the project into a state where it's at least usable and hopefully even useful.

Version 4 on PyPI 4.60.5.1

A first step was to put version 4.60.5 up on PyPI. Version 4.60.5.1 was posted this week so that pip install PySimpleGUI will provide a version of PySimpleGUI that's solid.

PySimpleGUI 6 - Back to LGPL3

There were several years of development that went into the PySimpleGUI 5 effort. Rather than have those bug fixes and new features languish and be useless, I'm releasing them as Open Source.

Not all of the Version 5 code is in 6. Things like the upgrade mechanism and of course the licensing has been removed. As far as functionality, it matches the SDK posted in the Docs.PySimpleGUI.com documentation.

What to expect ahead

Applications, Demo Programs, etc

The applications psgdemos, psgfiglet, psghotkey have all been upgraded to 6 and posted on GitHub and PyPI. The remaining applications are being updated as well.

Version 6 Uploaded to PyPI

On Tues 14-Apr-2026 PSG Version 6 was posted to PyPI. There were a LOT of changes that have been made over the years since version 4 was released. Hoping that it all goes well! Feel free to open an issue if you run into trouble.

Maintenance & Support

I don't have a firm grasp of the future beyond a few weeks at this point. If the past 8 years is any indication, I'm not very good at making predictions.

Installing

You can install the latest released version from PyPI with a simple:

PyPI

python -m pip install PySimpleGUI

Github

You can install the latest version straight from the PySimpleGUI GitHub repo without downloading the repo by running:

python -m pip install --upgrade https://github.com/PySimpleGUI/PySimpleGUI/zipball/master

If you want to download the repo then download/close and run in the downloaded folder:

python -m pip install .

More updates coming...

Changes are rolling out onto GitHub and PyPI every few days. They'll continue until everything gets switched over to Version 6.
