This is a large release!

v0.86.0 Adds an entirely new theming system and an updated demo (Run python -m textual).

The new theming system standardizes the look-and-feel of widgets. This should mean they will look pretty when used in combination, and you will need less tweaking of your UI. If your app already has a customized look and feel, you may need to make a few style changes. Let us know if you need any help with that (jump on the Discord server).

Here's what the demo looks like now:
