Wait, what?
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.
A first step was to put version 4.60.5 up on PyPI. Version 4.60.5.0 was posted this week so that pip install PySimpleGUI will provide a version of PySimpleGUI that's solid.
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.
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.
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.
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.
You can install the latest released version from PyPI with a simple:
python -m pip install PySimpleGUI
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 .
Changes are rolling out onto GitHub and PyPI every few days. They'll continue until everything gets switched over to Version 6.
