Expect Leo 6.8.7 on Friday, October 10

[Edward K. Ream]

Python 3.14 is planned for Tuesday October 7, so it would be convenient to release the next version of Leo three days later. Of course I'll release Leo 6.8.7 earlier if there is reason to do so.

I have just installed Python 3.14 without incident. All of Leo's tests pass on Windows. I plan to release Leo 6.8.7 this Friday, October 10, as scheduled.

Hi,

yesterday I updated my machine from Windows 10 to Winddos 11. Today, I completely removed all my old Python installations and then installed the new Python 3.14. From Python I did a fresh install of Leo from PyPi (`python -m pip install leo`) as described on the Leo website. During the install I got the following WARNING:

When I start leo, I get the following error:

The environment contains the correct paths to Python and Python\Scripts.

You installed the latest version of Leo from PyPI, which is version 6.8.6.1.

This version does NOT yet support Python 3.14.0 !

If you want to try it out before Edward releases version 6.8.7, you have to use the 'devel' branch from GitHub.

See https://leo-editor.github.io/leo-editor/installing.html#installing-leo-from-github

With kind regards,

I don't think that's it - PyQt6.sip normally gets installed during a PyQt6 installation.

I just installed Python 3.14 on Windows 11. Then I created a new virtual environment and pip-installed Leo into it. PyQt6.sip got installed and Leo ran normally. Something went wrong when @rengel tried installing Leo, I think, because PyQt6 didn't install normally.

I'd suggest creating a venv like I did and trying it that way.
