The Freddy's hotfix Release

Hotfix to fix saving screenshots on Windows

[0.85.1] - 2024-10-26

Fixed

• Fixed encoding issue when saving files such as screenshots on Windows #5182

The Freddy's Revenge Release

This versions updates the demo app. The previous demo was written quite a while ago and needed a refresh. It's not quite finished (there are plenty more widgets to cover), but it is still a bug improvement over the old one.

python -m textual

Give it a shot, we think it is pretty fun to play with.
